What is the average rate of change of f(x)=1/4x^2-4 over the interval from 0 to 3?

Answers

Answer:

1/4

Step-by-step explanation:

To find the average rate of change we find

f(3) -f(0)

----------

3-0

We need to find f(3) = 1/4 (3)^2 -4 = 1/4 (9) -4 = 9/4 -4 = -7/4

f(0) = 1/4 (0)^2 - 4 = -4

f(3) -f(0)

3-0

-7/4 - (-4)

9/12

1/4

Answer:

3/4

Step-by-step explanation:

The x values are 0 and 3. Use the formula y2-y1/x2-x1

Plug in the x factors into the orginal equation. Should look like the equations below:

f(x)=1/4(0)^2-4 -------> -4

f(x)=1/4(3)^2-4 --------> -7/4Now plug it in to the formula we saved earlier.

-7/4-(-4)/3-0= -7/4+4/3= -7/4+16/4/3

Then simplify it.

9/4/3, and in this case we have a fraction in a fraction and when this happens just multiply the equation by the x variables reciprical which in this case the x is 3 so the equation is multiplied by 1/3 and you would get 9/12. Now simplify that and you get 3/4.

You use 6 gallons of water on 20 plants in your garden. At that rate, how much water will it take to water 30 plants?

Answers

9 because every ten plants is equal to 3 gallons. 30 plants are equal to 9 gallons.
tell me if if helps.

9 because if you divide 6 by 2 you get 3 and if per 10 plants you have to use 3 gallons then for 30 you'll have to use nine because 3x3 equals 9

Solve the system of equations below.
(x+y=21
2x = 33+ y

Answers

Answer:

(18, 3 )

Step-by-step explanation:

Given the 2 equations

x + y = 21 → (1)

2x = 33 + y → (2)

Rearrange (2) expressing y in terms of x by subtracting 33 from both sides

y = 2x - 33 → (3)

Substitute y = 2x - 33 into (1)

x + 2x - 33 = 21, that is

3x - 33 = 21 ( add 33 to both sides )

3x = 54 ( divide both sides by 3 )

x = 18

Substitute x = 18 into (3) for corresponding value of y

y = (2 × 18) - 33 = 36 - 33 = 3

Solution is (18, 3 )

Answer:

Step-by-step explanation:

x+y = 21 —> (A)

2x = 33 + y — (B)

Form eq B

2x = 33 + y

Or y = 2x - 33

By putting the value of y in equation A

x + 2x -33 = 21

3x = 21 + 33

3x = 54

x = 54/3

x = 18

Now,

y = 2 (18) -33

= 36 - 33

= 3

Thus, s.s ={( 18,3)}
