f(n) = n^3– 2n
g(n)= 2n + 2
Find (f •g)(n)

Answers

Answer 1

Answer:

[tex]\boxed{(f~.~g)(x) = 2n^4 + 2n^3 - 4n^2 -4n}[/tex]

.

Step-by-step explanation:

We know that

[tex]f(n) = n^3 - 2n[/tex]

[tex]g(n) = 2n + 2[/tex]

.

So

[tex](f~.~g)(x) = f(n)~.~g(n)[/tex]

[tex](f~.~g)(x) = (n^3-2n)(2n + 2)[/tex]

[tex](f~.~g)(x) = n^3(2n + 2) - 2n(2n + 2)[/tex]

[tex](f~.~g)(x) = 2n^4 + 2n^3 - 4n^2 -4n[/tex]

Step-by-step explanation:

Looks like a trick question. The first number after the decimal is a tenth, the next one a hundredth. There is no thousandth to round up the hundredth and so the number is already rounded.

Write an express for the perimeter of the figure shown by combing like terms.

Answers

Answer:

  28k

Step-by-step explanation:

The perimeter is the sum of the four equal-length sides:

  P = 7k +7k +7k +7k

  P = k(7 +7 +7 +7)

  P = 28k . . . . perimeter of the rhombus

Of course, multiplication was invented to make repeated addition easier. Here, the perimeter is 4(7k) = 28k, no like terms to combine.

Step-by-step explanation:

A large aquarium should contain 10,000 liters of water when it is filled correctly. Fish will get sick if the aquarium gets down to 4,000 liters or less. One day over the weekend, there is an accident, and the tank cracks in 4 places, causing water to empty out of the aquarium at a rate of 20.5 liters per hour. The aquarium workers did not catch the leaks until 2 days later. How much water was left in the tank when the aquarium workers finally caught the leak? Based on the level of water, were fish sick?

Answers

Answer:

9016 litres left

Step-by-step explanation:

The fish were not sick.

You would multiply 20.5 by 48 which is the amount of hours in 2 days then subtract that amount from 10000 to see how much is left

Grace rakes leaves everyday for one week. She fills the same number of bags with leaves on each of the 5 weekdays. She fills 11 bags over the weekend. At the end of the week, Grace has filled a total of 26 bags. She wants to know how many bags she filled each weekday.

Answers

Answer:

3 bags per weekday

Step-by-step explanation:

Total bags of leaves at the end of the week = 26 bags

Bags of leaves she fills over the weekend = 11 bags

Bags of leaves she fills during weekdays = x bags

Total bags of leaves at the end of the week = Bags of leaves she fills over the weekend + Bags of leaves she fills during weekdays

26 = 11 + x

Subtract 11 from both sides

26 - 11 = 11 - 11 + x

15 = x

x = 15 bags

If she fills the same number of bags with leaves on each of the 5 weekdays.

how many bags she filled each weekday.

Bags she filled each weekday = Total Bags of leaves she fills during weekdays / 5 weekdays

= 15 bags / 5 weekdays

= 3 bags per weekday

Answer:

3

Step-by-step explanation:

1. Bags filled on weekdays + bags filled on weekends = total bags filled

2. 5b + 11 = 26

3. Isolate variable (subtract 11 from both sides) = 5b=15

4. Divide both sides by 5 = 15/5 = 3

5. How many bags does Grace fill each weekday? = 3

Answer:

slope intercept form:

y=mx+b where m is the slope and b is the y intercept.

The y intercept is where the line crosses the y axis which in this example is at (0, 2). The y intercept is 2. The slope can be found by plugging in the x and y values of any 2 points on the line into the equation: y2 - y1 / x2- x1:

y2 - y1 / x2- x1

4-2 / 5-0

2/5 is the slope

therefore, y=2/5x+2 is the equation

In a direct variation equation F(x)=6 when x=4

Answers

Answer: C. f(x)=1.5x

Step-by-step explanation:

Here's the complete question:

In a direct variation equation f(x) = 6 when x = 4. what is the direct variation equation

A-f(x)=6x

B-f(x)=4x

C-f(x)=1.5x

D-f(x)=0.67x

The direct variation equation will be:

6 = kx

When x = 4, this will be:

6 = 4k

k = 6/4

k = 1.5

Therefore, the direct variation equation is: f(x)=1.5x
