Answer:

see explanation

Step-by-step explanation:

To find the terms of the sequence substitute n = 1, 2, 3, 4, 10 into the rule.

n = 1 → 2(1)² = 2(1) = 2

n = 2 → 2(2)² = 2(4) = 8

n = 3 → 2(3)² = 2(9) = 18

n = 4 → 2(4)² = 2(16) = 32

n = 10 → 2(10)² = 2(100) = 200

The first 4 terms are 1, 8, 18, 32 and the 10 th term is 200

Answer:

2, 8, 18, 32.

10th term =  200.

Step-by-step explanation:

The first 4 terms of 2n^2 are

2(1)^2,  2(2)^2,   2(3)^2, 2(4)^2

= 2, 2*4, 2*9, 2*16

= 2, 8, 18, 32.

The 10th term = 2(10)^2

= 200.

Answer:

First of all, before writing the y-intercept you need to make sure that the equation is in slope intercept form.

x + 3y = 14

3y = 14 - x

y = 14/3 -x/3

y= -x/3 + 14/3

                         14/3 is the y-intercept

The y-intercept of the line with equation x + 3y = 14 is 4.67.

The equation of the line is in the form x + 3y = 14. To find the y-intercept, we need to set x = 0 and solve for y. Plugging in x = 0, we get 0 + 3y = 14. Simplifying the equation gives us 3y = 14. Dividing both sides by 3, we find that y = 4.67. Therefore, the y-intercept of the line is 4.67.

Answer: ≈ 8%

Step-by-step explanation:

Total number of students = total number of boys + total number of girls

Total number of students = 88 + 75

Total number of students =  163

10.2% of the boys have blue eyes , this means that 10.2% of 88 have blue eyes

[tex]\frac{10.2}{100}[/tex] x 88 = 8.976

Since we are dealing with humans , therefore , this means that 9 boys have blue eyes.

Also , 5.3% of the girls have blue eyes means that 5.3% of 75 have blue eyes. That is

[tex]\frac{5.3}{100}[/tex] x 75 = 3.975 , therefore : 4 girls have blue eyes.

In total , 13 students have blue eyes

Therefore , to calculate the % of students that have blue eyes , we have :

13/163 x 100 = 7.975460123

Therefore : ≈ 8% of the students have blue eyes

The three important tools of Federal Reserve's monetary policies are as follows:

Step-by-step explanation:

The monetary policies of the United States's central bank, Federal Reserve are the acts of the entity to influence money and raise the country's economy. These policies also helps in looking over the aspects of how the money and credits draw affects on credit rates and the overall performance of the U.S. Economy.

The three prime tools of the Federal reserve's monetary policies are the Open Market Operations, Discount Rates and the Reserve Requirements.

Open Market operations

This involves in purchase and selling process of government securities. The primary dealer with which the Reserve deals compete on the basis of prices and thus the dealer gets decided with whom the reserve deal for the day.

Discount Rates

This is the discount rate charged to depository institutions for short term loans by the Federal Reserve.

Reserve Requirements

This is the money or deposit amount the Reserve Bank must sustain in its vault or depository.

The correct answer is option 1: x = -4y+19

Step-by-step explanation:

Given equations are:

[tex]3x+2y=17\ \ \ Eqn1\\x+4y=19\ \ \ \ Eqn2[/tex]

When we have to solve a system of equations using substitution method we look for a variable in both of equations that is without any co-efficient as it is easy to isolate that variable in the equation and then using substitution method to solve it

We can see that in equation 2, x is without any co-efficient

So,

[tex]x+4y = 19[/tex]

Subtracting 4y from both sides

[tex]x+4y-4y = 19-4y\\x = 19-4y\\[/tex]

Can also be written as:

[tex]x = -4y+19[/tex]

Hence,

The correct answer is option 1: x = -4y+19

Answer:

The correct answer is option 1: x = -4y+19

Step-by-step explanation:

Answer:

1. We can see that salesperson's weekly income is the sum of her constant weekly salary ($760) and a commission which is variable and depends on her weekly sales.

So, if we say that y is her weekly income and x is her weekly sales, we can write this as:

y = 760 + 0.075x

Note that we had to change percentage to decimal number dividing it by 100.

2  Since for each value of x there is only one corresponding value of y, we can say that this is a function. For any value of x we input there is only one solution we get - that is the main feature of function and a way to tell if something is really a function.

Since this is a function, it can also be written as:

f(x) = 760 + 0.075x

3. Domain of a function is, basically, set of all values of x for which the function can work. That practically means that, since x is weekly sale, it can not be negative (one cannot make -$500 sale, for example). However, it is possible that she doesn't make a sale one week, making it possible for x to be 0. Also, the value of her sales doesn't have to be integer (it is quite possible that she makes $673.50 sale).

All this means that appropriate domain for this function are positive real numbers including 0.

Answer:

The answer is x = 1

Step-by-step explanation:

Let¿'s solve for x in the equation:

(x + 5)/4 = (2x + 1)/2

x + 5 = 2 * (2x + 1)

x + 5 = 4x + 2

-3x = 2 - 5

-3x = -3

x = 1

Proof of x = 1

1 + 5/4 = 2 + 1/2

6/4 = 3/2

3/2 = 3/2 (Dividing by 2 at the left side)

We proved that x = 1 is correct

m=(-5/4)(-4/15)

m=20/60

m=2/6

m=1/3

Answer:

1/3

Step-by-step explanation:

Question 1:

For this case we must solve the following system of equations by the method of elimination:

[tex]8x-6y=-20\\-16x+17y=30[/tex]

We multiply the first equation by 2:

[tex]16x-12y = -40[/tex]

We have the equivalent system:

[tex]16x-12y = -40\\-16x + 17y = 30[/tex]

We add the equations:

[tex]5y = -10[/tex]

We divide between 5 on both sides of the equation:

[tex]y = - \frac {10} {5}\\y = -2[/tex]

We find the value of the variable "x":

[tex]8x-6 (-2) = - 20\\8x + 12 = -20\\8x = -20-12\\8x = -32[/tex]

We divide by 8 on both sides of the equation:

[tex]x = - \frac {32} {8}\\x = -4[/tex]

Thus, the solution of the system is:

[tex](x, y): (- 4, -2)[/tex]

Answer:

[tex](x, y): (- 4, -2)[/tex]

Question 2:

For this case we must solve the following system of equations by the method of elimination:

[tex]-4y-11x = 36\\20 = -10x-10y[/tex]

We multiply the first equation by 10:

[tex]-40y-110x = 360[/tex]

We multiply the second equation by -4:

[tex]40y + 40x = -80[/tex]

We have the equivalent system:

[tex]-40y-110x = 360\\40y + 40x = -80[/tex]

We add the equations:[tex]-70x = 280[/tex]

We divide by -70 on both sides of the equation:

[tex]x = \frac {280} {- 70}\\x = -4[/tex]

We find the value of the variable "y":

[tex]-4y-11 (-4) = 36\\-4y + 44 = 36\\-4y = 36-44\\-4y = -8[/tex]

We divide between -4 on both sides of the equation:

[tex]y = - \frac {8} {- 4}\\y = 2[/tex]

Thus, the solution of the system is:

[tex](x, y): (- 4,2)[/tex]

Answer:

[tex](x, y): (- 4,2)[/tex]

Answer:

The solved expression is [tex]x=3+\sqrt{2}[/tex] and [tex]x=3-\sqrt{2}[/tex]

Therefore [tex]x=3\pm\sqrt{2}[/tex]

Step-by-step explanation:

Given quadratic equation is [tex]x^2-6x+7=0[/tex]

To solve the given equation by using completing the square :

[tex]x^2-6x+7=0[/tex]

Rewritting the above equation as below :

[tex]x^2-6x+7+2-2=0[/tex]

[tex](x^2-6x+7+2)-2=0[/tex]

[tex](x^2-6x+9)-2=0[/tex]

[tex](x^2-6x+3^2)-2=0[/tex]

[tex](x^2-2(x)(3)+3^2)-2=0[/tex]  ( it is of the form of [tex](a-b)^2=a^2-2ab+b^2[/tex]  heere a=x and b=3 )

[tex](x-3)^2-2=0[/tex]

[tex](x-3)^2=2[/tex]

Taking square root on both sides we get

[tex]\sqrt{(x-3)^2}=\pm\sqrt{2}[/tex]

[tex]x-3=\pm\sqrt{2}[/tex]

[tex]x=\pm\sqrt{2}+3[/tex]

[tex]x=3\pm\sqrt{2}[/tex]

Therefore [tex]x=3+\sqrt{2}[/tex] and [tex]x=3-\sqrt{2}[/tex]

Answer:

(1/5)(10/3) = 10/15 = 2/3 mile

The friend lives [tex]$\frac{2}{5}$[/tex] of a mile away.

To solve this problem, we need to calculate the total distance based on the speed at which the bike is ridden and the time it takes to reach the friend's house.

First, we determine the speed at which the bike is ridden, which is given as [tex]$\frac{1}{5}$[/tex] of a mile per minute.

Next, we calculate the time it takes to reach the friend's house, which is [tex]$3\frac{1}{3}$[/tex] minutes. To work with this mixed number easily, we convert it to an improper fraction. [tex]$3\frac{1}{3}$[/tex] minutes is the same as [tex]$\frac{10}{3}$[/tex] minutes because [tex]$3\frac{1}{3} = 3 + \frac{1}{3} = \frac{9}{3} + \frac{1}{3} = \frac{10}{3}$[/tex].

Now, we can find the total distance by multiplying the speed by the time:

[tex]\[ \text{Distance} = \text{Speed} \times \text{Time} \][/tex]

[tex]\[ \text{Distance} = \frac{1}{5} \text{ mile/minute} \times \frac{10}{3} \text{ minutes} \][/tex]

When we multiply these two fractions, we multiply the numerators together and the denominators together:

[tex]\[ \text{Distance} = \frac{1}{5} \times \frac{10}{3} \][/tex]

[tex]\[ \text{Distance} = \frac{1 \times 10}{5 \times 3} \][/tex]

[tex]\[ \text{Distance} = \frac{10}{15} \][/tex]

We can simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 5:

[tex]\[ \text{Distance} = \frac{10 \div 5}{15 \div 5} \][/tex]

[tex]\[ \text{Distance} = \frac{2}{3} \][/tex]

Therefore, the friend lives [tex]$\frac{2}{5}$[/tex] of a mile away.

Answer:

No, the books had more sales by 5/6 being bigger (Greater Than) than 3/4.

By converting both fractions to have a common denominator of 12, it becomes clear that there were more books than toys for sale, as 10/12 (books) is greater than 9/12 (toys).

To determine whether there were more toys or books for sale, we need to compare the fractions ⅓ (representing toys) and ⅗ (representing books). To compare these fractions, they must have a common denominator. The least common denominator for 4 and 6 is 12. Converting both fractions to have the denominator of 12, you would get:

When comparing 9/12 (toys) to 10/12 (books), it is clear that there were more books than toys for sale since 10/12 is greater than 9/12.

Step-by-step explanation:

yes it is a factor because 31 is a factor and if u add there is a one

Final answer:

Yes, 3 is a factor of 81 because the sum of 81's digits (8 and 1) is 9, which is divisible by 3. Also, since 81 is 3 raised to the power of 4, 3 is repeatedly a factor of 81.

Explanation:

To determine if 3 is a factor of 81, we can use the concept of divisibility. A number is divisible by 3 if the sum of its digits is divisible by 3. The number 81 only consists of the digits 8 and 1, and when added together (8 + 1), they equal 9. Since 9 is divisible by 3, so is 81. Therefore, 3 is indeed a factor of 81.

Additionally, the three-factor product rule can confirm this, as combining the factors 3, 3, and 3 (since 3 x 3 x 3 = 27, and 27 x 3 = 81), you end up with 81, which proves that 3 is a factor of 81.

The segment BM is a perpendicular bisector segment AD

so

In the right triangle ABM

Applying the Pythagorean Theorem

[tex]BM^2=AB^2-AM^2[/tex]

we have

[tex]AB=5\ units\\AM=x\ units[/tex]

substitute

[tex]BM^2=5^2-x^2[/tex]

[tex]BM^2=25-x^2[/tex] -----> equation A

In the right triangle BMC

Applying the Pythagorean Theorem

[tex]BM^2=BC^2-MC^2[/tex]

[tex]BM^2=7^2-(9-x)^2[/tex]

[tex]BM^2=49-(81-18x+x^2)[/tex]  

[tex]BM^2=49-81+18x-x^2[/tex]

[tex]\text{Consider the form } x^2+bx+c[/tex]

Find a pair of integers whose product is c and and whose sum is b

[tex]\text{Compare } x^2-2x-3 = 0 \text{ with } x^2+bx +c\\\\\text{We get } b = -2 \text{ and } c = -3[/tex]

Now find, a pair of integers whose sum is -2 and product is -3

The integers that satisfies this condition is -1 and 3

When we add - 1 and 3 we get 2

When multiply -1 and 3 we get -3

Thus the pair of integers are -1 and 3

Write the factored form using these integers.

[tex](x-1)(x+3) = 0[/tex]

The Zero Product Property states that if ab = 0, then either a = 0 or b = 0, or both a and b are 0

Set the factors equal to 0

Given Will ran the diagonal distance across a square field measuring 40 yards each sides .

∴The distance covered by Will was =[tex]\sqrt{40^{2}+40^2 }[/tex] yards

                                                         = [tex]40\sqrt{2}[/tex] yards=56.56 yards

Again James ran diagonal distance across a rectangle field with a length of 25 yards and a width of 35 yards.

So,distance covered by James was =[tex]\sqrt{25^2+35^2}[/tex] yards

                                                             =[tex]5\sqrt{74}[/tex] yards = 43.01 yards

∴Will ran longer distance.

∴Will ran 13.55 yards more than James.

To calculate the longer distance Will ran compared to James, find the diagonal distances each ran. Will ran approximately 13.56 yards longer.

To determine how much longer Will ran compared to James, we need to calculate the diagonal distances for each run.

Will ran 56.57 - 43.01 ≈ 13.56 yards longer than James. Thus, Will ran around 13.56 yards longer than James, as determined by subtracting the diagonal of the rectangular field from that of the square field. This calculation offers a quantitative measure of the difference in running distances, providing insight into their comparative performances.

This equation means what would f(x) be if x was -2. F(x) is another way to write y. So this equation can be rewritten as y = 2(-2) - 3.
