Answer:

The ratio of side lengths is 4:15

The ratio of areas as a fraction is 16/225

Step-by-step explanation:

We can probably assume the triangles are similar. If that is the case, the smaller triangle is 4/15s the size of the blue triangle. That makes the ratio 4:15.

As for the ratio of areas, areas are expressed in length^2. Inches squared, centimeters squared, meters squared, or whatever length. It is always a length squared.

Similarly, the ratio of the length can be squared to give the ratio of the areas. The ratio of the areas is 4^2 / 15^2 = 16/225

Find the average rate of change of f(x)=2x-1 from x=-1 to x=2

MrMuchimi

The average rate of change from x = -1 to x = 2 is 2

Solution:

Given function is:

f(x) = 2x - 1

We have to find the average rate of change from x = -1 to x = 2

The average rate of change is given as:

$\text {Average rate of change}=\frac{f(b)-f(a)}{b-a}$

The average rate of change from x = -1 to x = 2 is given by formula:

$\text {Average rate of change}=\frac{f(2)-f(-1)}{2-(-1)}\\\\\text {Average rate of change}=\frac{f(2)-f(-1)}{3}$

Find f(2) and f( - 1)

Substitute x = 2 in given function

f(2) = 2(2) - 1 = 4 - 1 = 3

Substitute x = -1 in given function

f( - 1) = 2(-1) - 1 = -2 - 1 = -3

Substitute the values in above formula,

$\text {Average rate of change}=\frac{3-(-3)}{3}=\frac{6}{3}=2$

Thus average rate of change from x = -1 to x = 2 is 2
