Answer:

C

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos45° = \frac{\sqrt{2} }{2} , then

cos45° = \frac{adjacent}{hypotenuse} = \frac{s}{6} = \frac{\sqrt{2} }{2} ( cross- multiply )

2s = 6\sqrt{2}  ( divide both sides by 2 )

s = 3\sqrt{2} → C

Select the correct answer.
Leviafan [203]

Answer:

The graph of function g is the graph of function f shifted 6 units up.

Step-by-step explanation:

Given

f(x) = 2^x

g(x) =2^x + 6

Required

Compare g(x) to f(x)

Substitute f(x) = 2^x in g(x) =2^x + 6

g(x) = f(x) + 6

<em>This implies that f(x) is shifted 6 units upward to give g(x)</em>
