Answer:

5 feet & 15 feet

Step-by-step explanation:

The question is to find the lengths of 2 sides of the rectangle.

Solution:

Let shorter side be "x"

Let longer side be "y"

From the question, we can write:

y = 3x

also

y - x = 10

Now, putting the first on second equation, we get:

y - x = 10

3x - x = 10

2x = 10

x = 10/2 = 5

Now, y = 3x, y = 3(5) = 15

So we can say the lengths of 2 sides of the rectangle is 5 feet & 15 feet

The graph of an exponential function, f(x), is shown. Move numbers to the blanks to describe how f(x) increases and grows over d

yawa3891 [41]

By looking at the graph we can see that f(x) increase by 1 (on the vertical axis . or y-axis ) from 2 to 3, over the interval 0 to 1 ( horizontal axis, or x-axis)

It increases by 2 over the interval 1 to 2.

by 4 over the interval 2 to 3.

And by 8 over the interval 3 to 4.

Therefore this exponential function grows by a factor of 2 (since it doubles every by every interval of 1)
