Sure thing!

So if we look at the function, it is an exponential, meaning that it is a number to the power of x
The graph can be described by the equation

y = a^x

If we look at the graph, one of the points on the line is (2, 16), the x value is 2 and the y value is 16

If we consider this along with the function for the graph, we can say that

16 = a^2

Just solve this for a and you’ll have your answer :)

Geri believed the answer to one of her homework problems was 2 cubed. After checking her work, she realized the correct answer w

TiliK225 [7]

Answer:

The correct answer is 64 times Geri’s original answer

Step-by-step explanation:

Given

Gari's Answer: 2³

Correct Answer: 2⁹

Required:

Relationship between both answers

Let Gari's answer be represented by G and the Correct answer be represented by C; Such that

G = 2³

C = 2⁹

Divide C by G

$\frac{C}{G} = \frac{2^9}{2^3}$

From law of indices, $\frac{a^m}{a^n} = a^{m-n}$

Applying this law, we have

$\frac{C}{G} = 2^{9-3}$

$\frac{C}{G} = 2^{6}$

$\frac{C}{G} = 2*2*2*2*2*2$

$\frac{C}{G} = 64$

Multiply both sides by G

$G * \frac{C}{G} = 64 * G$

$C = 64G$

Hence, we can conclude that the correct answer is 64 times Geri’s original answer

P( 4) =<br> 13 and Q( 4) = 8, evaluate P( 4) Q(4).

mariarad [96]

This is a common multiplication problem. Imagine P(4) as x, and Q(4) as y. You are plugging them into the equation x*y. Since x is equal to 13, and y is equal to 8, you are going to plug them into their corresponding variables and multiply. 13 * 8 = 104. The answer is 104.
