√−100 = ___ +_____i
...

Answers

Answer 1
Final Answer:

The square root of -100 is 0 + 10i or simply 10i in the form of a complex number, representing the imaginary part along the complex plane's imaginary axis.

Explanation:

The square root of a negative number is not a real number, but rather a complex number denoted by the imaginary unit i for the square root of -1. To find the square root of -100, express -100 as the product of its prime factors: [tex]\(-100 = -1 \times 2^2 \times 5^2\)[/tex]. Then, applying the properties of square roots, break it down: [tex]\(\sqrt{-1} \times \sqrt{2^2} \times \sqrt{5^2}\)[/tex].

The square root of -1 is represented as i, while the square roots of [tex]\(2^2\)[/tex] and [tex]\(5^2\)[/tex] are 2 and 5, respectively. Combining these results, the square root of -100 is 0 + 10i, or simply 10i in complex number form, indicating that it lies on the imaginary axis of the complex plane.

It's important to note that the square root of a negative number results in a complex number with a real part of 0 and an imaginary part that represents the square root of the positive value of the number. In this case, the square root of -100 yields an imaginary component of 10i, indicating the distance from 0 along the imaginary axis in the complex plane, demonstrating the nature of complex numbers when dealing with square roots of negative values.

Draw to show the numbers write the number to solve. Charlie gathering apples pears and plums the number of apples and plums are 10 partners there are the same number of apples and pears how many pieces of fruit could Charlie gather?

Answers

Answer:

Charlie could gather 30 pieces of fruit.

Fetching Information:

As Charlie has gathered apples pears and plums, and the number of apples and plums are 10 partners, and also there are same number of apples and pears.

What to Determine?

How many pieces of fruit could Charlie determine?

Solution:

Let 'a' be the number of apples, 'b' be the number of plums, and 'c' be the number of pears.

As the number of plums and apples is same i.e both are 10 in numbers.

So, a = b = 10

Note that number of pears and apples is also same. So, the the total number of pears will be 10.

So, c = 10

Total number of pieces of fruit = number of apples + number of plums + number of pears

Hence,

            Total number of pieces of fruit = a + b + c

                                                                 = 10 + 10 + 10

                                                                  = 30

Thus, Charlie could gather 30 pieces of fruit.

Mason has an offer to buy an item with a sticker price of $14,800 by paying

8530 a month for 36 months. What interest rate is Mason being offered?

A 12.8%

B. 25.7%

C6.4%

d8,5%

Answers

Answer:

8.83%

Step-by-step explanation:

Using compound interest formula

A = P ( 1+ r) ^t where A = amount = 530 × 36 = $ 19080, P = the amount of the loan = $ 14800, t = 36 / 12 = 3 years

substitute the values into the equation

19080 = 14800 (1 + r) ^3

19080 / 14800 = (1 + r) ^3  

1.2892 = (1 + r) ^3  

∛(1.2892) = 1 + r

1.0884 = 1 + r

r = 1.0884 - 1 = 0.0884 × 100 = 8.83%

Answer:

d 8,5%, the most probable, provided the error in the question is confirmed!!!

Step-by-step explanation:

Mason has an offer to buy an item with a sticker price of P= $14,800.

He is to pay $8530 a month for 36 months.

Total amount paid by Mason will be

$8530*36= $307,080

This will be very outrageous compared to the sticker price!!!

If we presume he is paying yearly 8530 for 36 months or 3 years.

Then total amount paid will be 8530*3 = $25590

Also very high in my opinion.

Perhaps the dollar sign was wrongly typed as '8' in the question and he pays only $530 monthly,

Then the total amount paid will be $19,080

This is quite reasonable.

If the interest rate is compounded for n (n=3, 36 months = 3 years)

years, thus

19080= ((P*(1+i)^n) , meaning

19080 =((14800(1+i)^3), which when evaluated yields

i=8.8%

Determine whether y2=3x+1 is a function.

Answers

Final answer:

The equation y2=3x+1 is a function.

Explanation:

Determine whether y2=3x+1 is a function

A function is a relation in which each input has exactly one output. To determine if the equation y2=3x+1 is a function, we need to check if each input value of x corresponds to exactly one output value of y.

In this case, the equation represents a quadratic curve, which passes the vertical line test, meaning that it is indeed a function.

For example, when x=1, we can substitute it into the equation as follows: y2 = 3(1) + 1 = 4.

Therefore, for every value of x, there is a unique value of y, indicating that the equation y2=3x+1 is a function.

-15x + 4 < 109 or -6x + 70 > - 2

Answers

For this case we must find the solution set of the given inequalities:

[tex]-15x + 4 <109[/tex]

We subtract 4 from both sides of the inequality:

[tex]-15x <109-4\\-15x <105[/tex]

We divide between 15 on both sides of the inequality:

[tex]-x <\frac {105} {15}\\-x <7[/tex]

We multiply by -1 on both sides taking into account that the sense of inequality changes:

[tex]x> -7[/tex]

The solution is given by all values of x greater than -7.

[tex]-6x + 70> -2[/tex]

Subtracting 70 from both sides of the inequality:

[tex]-6x> -2-70\\-6x> -72[/tex]

We divide by 6 on both sides of the inequality:

[tex]-x> - \frac {72} {6}\\-x> -12[/tex]

We multiply by -1 on both sides taking into account that the sense of inequality changes:

[tex]x <12[/tex]

Thus, the solution set is given by:

[tex]x> -7\ U\ x <12[/tex]

Therefore the solution is all real numbers.

Which ordered pair is a solution to the system of inequalities?
y> 2x
y> 7
A. (4,8)
B. (0,0)
c. (3,7)
D. (1,9)

Answers

Answer:

D

Step-by-step explanation:

To determine which ordered pair is a solution.

Substitute the x and y values into the inequalities.

Note that both must be true for the pair to be a solution of the system.

(4, 8)

8 > 2(4) → 8 > 8 ← False

8 > 7 ← True

(0, 0)

0 > 2(0) → 0 > 0 ← False

0 > 7 ← False

(3, 7)

7 > 2(3) → 7 > 6 ← True

7 > 7 ← False

(1, 9)

9 > 2(1) → 9 > 2 ← True

9 > 7 ← True

Thus (1, 9) is a solution to the system of equations. → D

Final answer:

The ordered pair (1,9) is the solution to the system of inequalities.

Explanation:

To determine which ordered pair is a solution to the system of inequalities, we need to check if each pair satisfies both inequalities. Let's check:

A. (4,8): For y > 2x, 8 > 2(4) = 8 > 8, which is false. For y > 7, 8 > 7, which is true. Therefore, (4,8) is NOT a solution to the system.

B. (0,0): For y > 2x, 0 > 2(0) = 0 > 0, which is false. For y > 7, 0 > 7, which is false. Therefore, (0,0) is NOT a solution to the system.

C. (3,7): For y > 2x, 7 > 2(3) = 7 > 6, which is true. For y > 7, 7 > 7, which is false. Therefore, (3,7) is NOT a solution to the system.

D. (1,9): For y > 2x, 9 > 2(1) = 9 > 2, which is true. For y > 7, 9 > 7, which is true. Therefore, (1,9) is a solution to the system.

A rectangular field is 400 meters long and 350 M wide what is the area of the field in square kilometers do not round the answer and be sure to include the correct unit in the answer

Answers

Final answer:

The area of a rectangular field that is 400 meters long and 350 meters wide is calculated by multiplying the length and width in meters to get square meters and then converting to square kilometers. The field's area is 0.14 square kilometers.

Explanation:

To calculate the area of a rectangular field, you multiply the length by the width. The area is usually given in square units.

In this case, the field is 400 meters long and 350 meters wide. To find the area in square meters, we do the following calculation:

Area = Length × Width

Area = 400 m × 350 m

Area = 140,000 m2

To convert square meters to square kilometers, you need to remember that 1 square kilometer equals 1,000,000 square meters. Therefore, you divide the area in square meters by 1,000,000 to get the area in square kilometers:

Area in square kilometers = Area in square meters / 1,000,000

Area in square kilometers = 140,000 m2 / 1,000,000

Area in square kilometers = 0.14 km2

The area of the field is 0.14 square kilometers.

Final answer:

To find the area of the rectangular field in square kilometers, the measurements of 400 meters and 350 meters must first be converted to kilometers, resulting in an area of 0.14 square kilometers.

Explanation:

To calculate the area of a rectangular field in square kilometers, we can use the formula for the area of a rectangle which is length × width. First, we need to convert the measurements into the same unit, so we will convert meters to kilometers. We know that 1 kilometer is equivalent to 1000 meters. Therefore, a field that is 400 meters long is 0.4 kilometers long (400 ÷ 1000 = 0.4 km), and a field that is 350 meters wide is 0.35 kilometers wide (350 ÷ 1000 = 0.35 km).

Now, with both measurements in kilometers, we can find the area:

To find the area of a rectangular field, you need to multiply its length by its width. In this case, the length is 400 meters and the width is 350 meters. So, the area of the field is 400 * 350 = 140,000 square meters.To convert this to square kilometers, we need to divide the area by 1,000,000 (since there are 1,000,000 square meters in a square kilometer). So, the area of the field in square kilometers is 140,000 / 1,000,000 = 0.14 square kilometers.Therefore, the area of the rectangular field is 0.14 square kilometers.

b. Graph the equation using x- and y- intercepts.

Answers

Answer:

linear equation in Standard form that can be used to determine how many of each prize Caleb can buy is [tex]1.25x+ 2.50y = 25[/tex]

Step-by-step explanation:

Given:

Total cost spent on prizes for games = $25

Cost of one lip balm = $1.25

Cost of one mini notebook  = $2.50

A) linear equation in STANDARD FORM that can be used to determine how many of each prize she can buy.

Let the number of lip balms be x and the number of mini note books be y. Then

[tex]1.25x+ 2.50y = 25[/tex]

B. Graph the equation using x- and y- intercepts.

Now by trial and error method

[tex]1.25(0)+ 2.50(10) = 25[/tex]

[tex]1.25(2)+ 2.50(9) = 25[/tex]

[tex]1.25(4)+ 2.50(8) = 25[/tex]

[tex]1.25(6)+ 2.50(7) = 25[/tex]

[tex]1.25(8)+ 2.50(6) = 25[/tex]

[tex]1.25(10)+ 2.50(5) = 25[/tex]

[tex]1.25(12)+ 2.50(4) = 25[/tex]

[tex]1.25(14)+ 2.50(3) = 25[/tex]

[tex]1.25(16)+ 2.50(2) = 25[/tex]

[tex]1.25(18)+ 2.50(1) = 25[/tex]

[tex]1.25(20)+ 2.50(0) = 25[/tex]

Thus Caleb can buy 0,2,4,6,8,9,10,12,14,1,6,18,20 lip balms and

1) [tex]- \frac{4}{5}x (- 2x + 4y - 5)[/tex]

= [tex]- \frac{4}{5}x \times (- 2x) +  - \frac{4}{5}x \times (4y) + - \frac{4}{5}x \times (- 5)[/tex]  

{By distributive property of multiplication}

= [tex]\frac{8}{5} x^{2}  - \frac{16}{5} xy + 4x[/tex] (Answer)

2) [tex]2y^{2}( \frac{1}{2} x + \frac{2}{6}y - 4z)[/tex]

= [tex]2y^{2} \times (\frac{1}{2} x) + 2y^{2} \times ( \frac{2}{6}y) - 2y^{2} \times (4z)[/tex]

{By distributive property of multiplication}

= [tex]xy^{2} + \frac{2}{3}y - 8y^{2}z[/tex] (Answer)

On a coordinate plane, a dashed straight line has a negative slope and goes through (0, 2), and (1, negative 1). Everything to the right of the line is shaded. The solutions to the inequality y > −3x + 2 are shaded on the graph. Which point is a solution? (0, 2) (2, 0) (1, −2) (−2, 1)

Answers

Answer:

(2,0)

Step-by-step explanation:

we know that

If a ordered pair is a solution of the inequality, then the ordered pair must satisfy the inequality

we have

[tex]y > -3x+2[/tex]

Substitute the value of  x and the value of y of each point in the inequality and then compare the results

case a) (0, 2)

[tex]2 > -3(0)+2[/tex]

[tex]2 > 2[/tex] ----> is not true

so

the point not satisfy the inequality

therefore

The point is not a solution of the inequality

case b) (2,0)

[tex]0 > -3(2)+2[/tex]

[tex]0 > -4[/tex] ----> is true

so

the point satisfy the inequality

therefore

The point is a solution of the inequality

case c) (1, -2)

[tex]-2 > -3(1)+2[/tex]

[tex]-2 > -1[/tex] ----> is not true

so

the point not satisfy the inequality

therefore

The point is not a solution of the inequality

case d) (-2, 1)

[tex]1 > -3(-2)+2[/tex]

[tex]1 > 8[/tex] ----> is not true

so

the point not satisfy the inequality

therefore

The point is not a solution of the inequality

Step-by-step explanation:

y=-2x+5 was shifted down 7 units what equation is it now

Answers

Answer:

[tex]y=-2x-2[/tex]

Step-by-step explanation:

we have

[tex]y=-2x+5[/tex]

This is the equation of a line in slope intercept form

where

[tex]m=-2[/tex] ---> the slope

[tex]b=5[/tex] ----> the y-intercept

we know that

If the given line was shifted down 7 units, then the new y-intercept is equal to

[tex]b=5-7=-2[/tex]

The slope of the new line will be the same that the original line, because are parallel lines

so

The new equation is

[tex]y=-2x-2[/tex]

Which input value produces the same output value for the
two functions on the graph?
O
O x=-1
Ox= 0
O
Ox=4

Answers

Answer: [tex]d)x=4[/tex]

Step-by-step explanation:

The missing graph is attached. And the options are:

[tex]a)x=-1\\b)x=0\\c)x=3\\d)x=4[/tex]

By definition, a relation is a function if and only if each input value has one and only one output value.

It is important to remember that the input values are the values of "x" and the output values are the values of "y".

Observe the graph attached.

You can identify in the graph that the function f(x) and the function g(x) intersect each other at the following point:

[tex](4,3)[/tex]

Where the x-coordinate (input value) is:

[tex]x=4[/tex]

And the y-coordinate (output value) is:

[tex]y=3[/tex]

Therefore, you can conclude that the input value that produces the same output value for the  two functions on the graph, is:

[tex]x=4[/tex]

is y=17 a linear function

WHOEVER ANSWERS FIRST WILL RECEIVE BRAINLIEST AND EARN 100 PTS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!Harriet Tubman and the Underground RailroadIn 1849, Harriet Tubman learned that she and her brothers were to be sold. When owners experienced money problems, it often made it necessary for them to sell persons held in slavery and other property. Tubmans family had been broken before. Three of Tubmans older sisters were sold and lost forever to the family and to history.Tubman and her brothers decided to take their lives into their own hands and make the effort to stay together. They left the property in the darkness of night. But they soon turned back when her brothers, one of them a brand-new father, had second thoughts. Punishment for escaping was severe. A short time later, Tubman escaped alone. She made use of the Underground Railroad to go to Pennsylvania and to freedom. All Northern states had voted to not allow slavery by 1804. Tubmans biographer, Sarah Bradford, quoted Tubman recalling, When I found I had crossed that line, I looked at my hands to see if I was the same person. There was such a glory over everything; the sun came like gold through the trees, and over the fields, and I felt like I was in Heaven.As a reaction to the cruel institution of slavery, the Underground Railroad was formed in the early nineteenth century. But this railroad was neither underground, nor did it have anything to do with trains. Instead, it was an organization of people who helped persons held in slavery in the United States travel from the South to the North and to freedom. The network provided transportation, money, safe houses, and other resources to the travelers. Details about the routes and the stops were only shared among a few people to protect the entire group. In Southern states, people caught sheltering the travelers could be jailed up to six months and fined. Once travelers reached Northern cities, they received assistance finding jobs and housing from committees of abolitionists that raised money to help them.Once in Pennsylvania, Tubman could not enjoy her freedom. Too many of her family members and friends still lived in slavery. She returned home in 1850 and helped several family members make the move north. This was the first of many trips for Tubman as a conductor on the Underground Railroad. For almost a decade and in about thirteen separate trips, Tubman led approximately seventy people to freedom. She provided instructions to fifty to sixty others to help them escape.When the Fugitive Slave Act of 1850 was enacted, it meant even greater danger for persons who were held in slavery and especially for those who had escaped. The act stated that the U.S. government must help owners regain control of persons they had once held in slavery. People who had escaped, often called runaways, could be captured and returned to their owners. They had no chance of legal defense or protection from the government. Anyone who refused to follow the orders of the act could be heavily fined. Also, people who captured runaways and returned them to their owners could make a lot of money. Tubman changed the Underground Railroads routes to deal with this added threat. The last stop for travelers became Canada, where slavery was not allowed.Tubman took risks daily. She used her experience to develop strategies to keep the Underground Railroad network safe and running smoothly. For example, she advised persons held in slavery to escape on a Saturday night. Since Sunday was a day of rest, owners would not discover the escape until Monday. People were encouraged to travel at night and to travel in spring and fall, when the days were shorter and the weather was mild. Tubman became well-known in the abolition and womens rights communities because of her intelligence, courage, and leadership.One of Tubmans last trips on the Underground Railroad was to bring her parents north to Canada. It was especially dangerous because Tubmans father was already in trouble for having sheltered runaways in his home. Although her parents were elderly, the trip was a success. Shortly after this, the Civil War began and the Underground Railroad stopped operating. Tubman turned her attention to the war effort. She first worked as a nurse and a cook, but quickly volunteered as a scout and a spy to help the army free persons held in slavery.Tubman was proud of her accomplishments. In 1896, Tubman spoke at a womens suffrage convention, I was the conductor of the Underground Railroad for eight years, and I can say what most conductors can't say I never ran my train off the track and I never lost a passenger.
