Answer:

$180 {m}^{2}$

Step-by-step explanation:

The area of a trapezoid is given by:

$Area = \frac{1}{2} (sum \: of \: bases) \times h$

From the diagram, the bases are 17m 23m, and the the height is 12m.

We substitute the values into the formula to get:

$Area = \frac{1}{2} (17 + 13) \times 12$

$Area = \frac{1}{2} \times 30 \times 12$

$Area = 6 \times 30$

This implies that

$Area = 180 {m}^{2}$

When the function f(x) = 3(5)x is changed to f(x) = 3(5)x + 22, what is the effect?

Alex787 [66]

Answer:

The original function is an exponential growth function, and so is a new function, but it will be translated in to 2 units.

Step-by-step explanation:

The first function will have a horizontal asymptote at y = 0 and the second function will have a horizontal asymptote at y = 22.
