Answers

Answer 1

Answer:

-1, 2, 0.5, 0.5

Step-by-step explanation:

[tex]4x^4 - 8x^3 - 3x^2 + 7x - 2[/tex]

Using synthetic division for x=-1 we find that

-1             4    -8      -3    7   -2

                    -4       12   -9    2

-----------------------------------------------

              4     -12    9     -2    0

----------------------------------------------

Thus quotient is [tex]4x^3 - 12x2 + 9x - 2[/tex]

Again try synthetic division by x-2

2            4    -12    9    -2

                      8   -8     2

-----------------------------------

             4   -4      1       0

--------------------------------------

Thus quotient is [tex]4x^2-4x+1\\=(2x-1)^2[/tex]

Hence zeroes of the polynomial f(x) are

-1, 2, 0.5, 0.5

A rental company rents a luxury car at a daily rate of ​$37.68 plus​ $.25 per mile. Vanessa is allotted ​$120 for car rental each day. Write an equation to represent the cost C of renting a car and driving x miles. How many miles can Vanessa travel on the ​$120​?

Answers

0.25x + 37.68 = C

[The company charges $0.25 per mile (x) plus $37.68, and C is the total amount of money/cost]


Vanessa has $120 [total amount of money she is given per day],

Since this is the total amount of money she has/can pay with, you can plug in 120 for C

0.25x + 37.68 = 120     Subtract 37.68 on both sides

0.25x = 82.32        Divide 0.25 on both sides

x = 329.28


Vanessa can travel 329.28 miles on the $120

Final answer:

The equation representing the cost of renting a car is C = 37.68 + 0.25x. Setting this equation equal to Vanessa's budget of $120 and solving for x, we find that Vanessa can travel about 329 miles on her budget.

Explanation:

The cost of renting a car for a day can be represented by the equation C = 37.68 + 0.25x, where 'C' is the total cost and 'x' is the number of miles driven. Vanessa has $120 allotted for each day. Therefore to find out how many miles she can travel, we can set the equation equal to 120 and solve for 'x'.

So, 120 = 37.68 + 0.25x

Subtract 37.68 from both sides to isolate the term with 'x'.

82.32 = 0.25x

Finally, divide both sides by 0.25 to solve for 'x'.

x = 329.28

Therefore, Vanessa can travel approximately 329 miles on $120.

A solution is 20% bleach. Which graph represents the number of liters of bleach, y, contained in x liters of solution?

Answers

Answer: Choice D (lower right corner)

If we have x = 0 liters of solution, then we have y = 0.20*x = 0.20*0 = 0 liters of bleach. Therefore the point (0,0) is on the graph.

The point (10,2) is also on the graph because x = 10 leads to y = 0.20*x = 0.20*10 = 2; meaning 10 liters of solution points to 2 liters of bleach.

The only graph that has both points (0,0) and (10,2) is choice D in the lower right corner.

Answers

It all depends on the value of x. Remember that x must be greater than or equal to 2 or else the number under the square root sign will be negative, which will result in a complex number. The domain is 2<=x and the range is 0<=x.

The function h(x) = square root x-2 is a square root function that takes the input x, subtracts 2 from it, and then takes the square root of the result.

Explanation:

The function h(x) = √(x-2) represents a square root function. It takes the input x and subtracts 2 from it, and then takes the square root of the result. The function can be graphed as a curve that starts at (2, 0) and increases as x gets bigger. For example, if we plug in x = 4, h(4) = √(4-2) = √2.

The distance between them is the difference. The mathematical operation for difference is subtraction.

Distance is a unit of measurement. Measurements cannot be negative so the absolute value sign is used to ensure the difference is positive.

Final answer:

The correct expression representing the distance between two points, X and Y, on a number line is D. [-4+3], which uses the absolute value to ensure a positive distance.

Explanation:

The distance between two points X and Y on a number line can be calculated as the absolute value of the difference between their coordinates. In this case, the coordinates of X and Y are not provided, but we know we are looking for an expression that shows a positive distance regardless of whether X is to the left or to the right of Y on the number line. Therefore, we need the absolute value to ensure we get a non-negative result, which correctly represents the concept of distance.

Distance on a number line is given by the formula “|X - Y|”, which yields the magnitude of the difference between two points without considering direction, making it a positive number. Hence, the expression that represents the distance between two points, X and Y, on the number line in the provided options is D. [-4+3].

Using the provided expressions, [-4+3] means taking the absolute value of the result of “-4+3”, which indeed gives us the distance of 1 between the two points, since |-4+3| = |-1| = 1.

Answers

Final answer:

To find out how much dressing remains in the jar, subtract the amount of dressing poured onto the salad from the total amount of dressing made.

Explanation:

To find out how much dressing remains in the jar, we need to subtract the amount of dressing poured onto the salad from the total amount of dressing made.

Dakota combines 6 1/3 fluid ounces of oil and 2 3/8 fluid ounces of vinegar, which gives us a total of 8 17/24 fluid ounces of dressing.

She pours 2 1/4 fluid ounces of the dressing onto her salad. To find out how much dressing remains, we need to subtract 2 1/4 from 8 17/24. Converting the fractions to a common denominator, we have (55/24) - (9/4) = 46/24 - 9/4 = 37/24. This means that 37/24 fluid ounces of dressing remain in the jar.

2=(1+r)^38
[tex] \sqrt[38]{2} = 1 + r[/tex]
r=0.018
Interest rate:1.8%
Final answer:

The interest rate that will cause Helena's money to double in approximately 38 years is approximately 1.89%.

Explanation:

An interest rate is the percentage at which interest is charged or paid on a loan, investment, or financial instrument over a specified period. It represents the cost of borrowing money or the return on invested capital. Interest rates are set by financial institutions, central banks, and market forces and influence economic activity. They can be calculated by the rule of 72 as well.

To find the interest rate that will cause Helena's money to double in approximately 38 years, we can use the rule of 72. The rule of 72 states that by dividing 72 by the interest rate, we can estimate the number of years it takes for an amount to double. In this case, if we divide 72 by 38, we get an interest rate of approximately 1.89%.  Therefore, an interest rate of approximately 1.89% will cause Helena's money to double in approximately 38 years.

that means each monkey takes 1 min for one bananer so i think 6 monkeys

24 Doughnut will be eaten by 8 students in 9 minutes. 8 monkeys will eat 6 bananas in 6 mins.

Given,

Two students can eat 4 doughnuts in 6 minutes.

On taking time constant (say 6 min), 2 student eat 4 doughnuts,

So 1 student eat 2 doughnuts each in 6 minutes.

So, in 1 minute doughnut eaten by 1 student will be  [tex]\frac{2}{6}[/tex].

So, in 9 minute doughnut eaten by 1 student will be [tex](\frac{2}{6} \times 9=3)[/tex]

Finally, in 9 minute doughnut eaten by 8 student  will be [tex](3\times 8=24)[/tex].

Hence 24 Doughnut will be eaten by 8 students in 9 minutes.

Similarly,

Since 8 monkeys eat 8 bananas in 8 mins.

On taking time constant, 8 monkeys eat 8 bananas.

So, 1 monkey eat 1 banana in 8 min.

So, in 1 min 1 monkey will eat [tex](\frac{1}{8} )[/tex] banana.

So, 1 banana will be eaten by 8 monkeys in 1 min.

So, 6 banana will be eaten by [tex](8\times 6=48)[/tex] monkeys in 1 min.

Finally, the number of monkeys required to  eat 6 bananas in 6 min will be,

To solve this problem, we first need to figure out how much tax will be applied to Neil's purchase.  To do this, we need to multiply the tax rate (5%) by the cost of the washing machine ($445).  But, we can't multiply percentages unless we change them to decimal form first.  To do this, we need to divide the percentage by 100 (because 5 percent is a fraction out of a  total 100 percent) or move the decimal point two spots to the left.  This gives us the following:

0.05 * 445

If we compute this expression, we get:

$22.25

This means that Neil will be charged $22.25 in tax.  However, the question asks for the total cost including tax, so we must add the original cost of the washing machine to the tax.  

$445 + $22.25 = $467.25

Therefore, your answer is $467.25.

Hope this helps!

The answer is $467.25

5% of $445 is $22.25 (that would be tax)
