Answer:

a. [1,2]

m= \frac{9-0}{2-1}=9

b. [1,3.5]

m =\frac{17-0}{3.5-1}=6.8

c. [1,5]

m =\frac{0-0}{5-1}=0

d. [0,3.5]

m =\frac{17-(-5)}{3.5-0}=6.29

So then we can conclude that the highest slope is for the interval [1,2] and that would be our solution for the fastest average rate.

a. [1,2]

m= \frac{9-0}{2-1}=9

Step-by-step explanation:

Assuming that we have the figure attached for the function. For this case we just need to quantify the slope given by:

m = \frac{\Delta y}{\Delta x}

For each interval and the greatest slope would be the interval on which the volume of the box is changing at the fastest average rate

a. [1,2]

m= \frac{9-0}{2-1}=9

b. [1,3.5]

m =\frac{17-0}{3.5-1}=6.8

c. [1,5]

m =\frac{0-0}{5-1}=0

d. [0,3.5]

m =\frac{17-(-5)}{3.5-0}=6.29

So then we can conclude that the highest slope is for the interval [1,2] and that would be our solution for the fastest average rate.

a. [1,2]

m= \frac{9-0}{2-1}=9

BRAINLIEST. NEED HELP NOW!!!<br> What is the value of x?
Arturiano [62]

Answer:

x=10

Step-by-step explanation:

these are similar triangles

8             12

------   = -----------

x+4          2x+1


using cross products

8* (2x+1) = 12(x+4)

distribute

16x + 8 = 12x+48

subtract 12x from each side

16x-12x +8 = 12x-12x+48

4x+8 = 48

subtract 8 from each side

4x+8-8 = 48-8

4x = 40

divide by 4

4x/4 = 40/x

x =10
