HELP PLEASE!! TON OF POINTS. RIGHT ANSWERS ONLY REWARDED. MATH GENIUSES?

Nonamiya [84]

Answer:

The graph is shifted 1 unit right

The graph is shifted 2 units down

Step-by-step explanation:

We are given

Parent function as

$f(x)=2^{x+3}-3$

New function as

$g(x)=2^{x+2}-1$

we can also write as

$g(x)=2^{x+3-1}-3+2$

We can see that

1 is subtracted to x-value

and 2 is added to y-value

So, f(x) is shifted right by 1 unit

and

f(x) is shifted up by 2 unit

Use the inverse cosine to find the measure of angle Q.

Rom4ik [11]

Answer:

∠ Q ≈ 53.1°

Step-by-step explanation:

cos Q = $\frac{adjacent}{hypotenuse}$ = $\frac{QS}{QR}$ = $\frac{6}{10}$ , then

∠ Q = $cos^{-1}$ ( $\frac{6}{10}$ ) ≈ 53.1° ( to the nearest tenth )
