A satellite television company charges a one-time installation fee anda monthly service charge. The total cost is modeled by the function
y = 40 + 90x. Which statement represents the meaning of each part
of the function?
(1) y is the total cost, x is the number of months of service,
$90 is the installation fee, and $40 is the service charge per
month.
(2) y is the total cost, x is the number of months of service,
$40 is the installation fee, and $90 is the service charge per
month.
(3) x is the total cost, y is the number of months of service,
$40 is the installation fee, and $90 is the service charge per
month.
(4) x is the total cost, y is the number of months of service,
$90 is the installation fee, and $40 is the service charge per
month.

Answers

Answer 1
Answer:

Answer:

Option (2).

Step-by-step explanation:

A satellite T.V. company charges one time installation fees along with monthly service charge.

Total cost is modeled by the function y = 40 + 90x

Here y = Total cost charged by the company

A one time installation charges = $40

Service charge for a month = $90

and number of months for which service was used = x months

Therefore, Option (2) explains the function well.
Answer 2
Answer: the answer is 2 y= total installation cost. x is the variable representing the number of months of service and $40 is the fixed price while $90 is dependent on the xvalue

Whatis(2+0.4+0.6)

First we have to arrange the numbers in sequence...

2.0 \: + \: 0.4 \: + 0.6 \n 3.0 \: or \: 3

Here I have taken this 0 after the point ..as the rest of the digit are in tenths place or after the point...

The answer is 3.

We will not calculate the 0 as it does not have any value.

You have a bag with 30 fireballs and another bag with 42 jolly ranchers. For a party, you want to repackage the candy into smaller bags, and you want each bag to have the same number of fireballs and jolly ranchers and. How many bags will you be able to make?

Answers

Answer: 6 bags 5 fire balls and 7 jolly ranchers in one bad

Step-by-step explanation:Ok so you got 30 fire balls 42 ranchers what you can do is see like wow more ranchers in a bag we know that hmm 42/6 is ya know 7 and that 6 does it go into 30 yeah it does 30/6=5 so you got 5 fire balls and 7 jolly ranchers is each bag with 6 bags

Answer:

6 bags

Step-by-step explanation:

The GCF of 30 and 42 is 6.

30/6 = 5

42/6 = 7

To use all candy, put 5 fireballs and 7 jolly ranchers in each bag. You will make 6 bags.

Which of the following represents the factored form of f(x) = x3 − 81x?f(x) = x(x − 9)2
f(x) = (x + 9)(x − 9)
f(x) = x(x + 9)(x − 9)
f(x) = x(x2 − 9)

Answers

Factored form of f(x) = x^(3) -81x is equal to x(x+9)(x -9).

What is factored form?

" Factored form is defined as for the given polynomial product of the constant along with linear expressions."

Formula used

a^(2) -b^(2) =(a+ b)(a- b)

According to the question,

Given polynomial,

f(x) = x^(3) -81x

Simplify the given polynomial to get its factored form using formula,

x^(3) -81x\n\n= x(x^(2) -81)\n\n= x(x^(2) -9^(2) )\n\n= x(x+ 9)(x-9)

Hence, Option(C) is the correct answer.

You're original equation has a -81, so the factored form will have to have a positive and negative multiplying one another to achieve that...

0.0091 rounded to the nearest thousandths would be 0.009. This is because the 1 after the 9 is BEFORE 5 so it stays as 9, and we remove the 1.

Calculate the electrical energy consumed by a 1200W toaster in 10 minutes..

Answers

Power is determined through multiplying the square of the current, resistance and time. it is also determined by dividing energy by time

1. P = I^2 Rt = 6^2*1000*10*60 = 21. 6 MW
2. P = 4000 J/4s = 1000 W
3. P = 750 J/ 30 s = 25 W
4. P = 500 J/3600s = 0.139 W ; P = 1200J/10/60s = 2 W ; toaster needs more power
5. P = 1200 J/ 600s= 2 W
