E^x not equal to zero

Zina [86]

Answer:

$e^x \neq 0$

Step-by-step explanation:

We will prove this with the help of a contradiction:

Let as assume that $e^x = 0$

Multiplying both sides by $e^{-x}$

$e^x\times e^{-x} = 0\times e^{-x}\\e^0 = 0\\1 = 0$

which is not possible.

Hence, our assumption was wrong which led us to a contradiction.

Thus,

$e^x \neq 0$

The inverse of G(x) is a function.

poizon [28]

Answer:

False

Step-by-step explanation:

In order for the inverse of a relation to be a function, it must pass the horizontal line test. That is, a horizontal line cannot intersect the graph in more than one place. Here, the x-axis intersects the graph of G(x) in 3 places, so the inverse of G(x) is not a function.

Find the area of the polygon

larisa [96]

Answer:

$687.5 \: {ft}^{2}$

Step-by-step explanation:

Area of polygon = Area of square + Area of triangle

$= {25}^{2} + \frac{1}{2} \times 25 \times (30 - 25) \\ \\ = 625 +\frac{1}{2} \times 25 \times5 \\ \\ = 625 + \frac{1}{2} \times 125 \\ \\ = 625 + 62.5 \\ \\ = 687.5 \: {ft}^{2}$
