How do you find the average rate of change through an interval

soldier1979 [14.2K]

In order to find average rate of change over an interval, do the y2-y1/x2-x1. Solve y for x=9 and x= 4
y2 = -3(9-4)^2 + 3 = -72
y1 = -3(4-4)^2 + 3 = 3

Now, x2 matches with y2 and and x1 matches with y1 obviously...
-72 - 3/9 - 4 = -15

A cone with volume 5000 m³ is dilated by a scale factor of 15. What is the volume of the resulting cone? Enter your answer in th

Rasek [7]

Answer:

$40\ m^{3}$

Step-by-step explanation:

we know that

If two figures are similar then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z-----> scale factor

x-----> the volume of the dilated cone

y-----> the volume of the original cone

$z^{3}=\frac{x}{y}$

In this problem we have

$z=1/5$

$y=5,000\ m^{3}$

substitute and solve for x

$(1/5)^{3}=\frac{x}{5,000}$

$(1/125)=\frac{x}{5,000}$

$x=5,000/125=40\ m^{3}$
