Answer:
i am not 100% sure but i think it would be C
Answer:

Step-by-step explanation:
we have

This is a vertical parabola open downward (the leading coefficient is negative)
The vertex is a maximum
The vertex is the point (h,k)
The range of the function is the interval (-∞,k]
so

Convert the quadratic equation in vertex form
Factor -1 leading coefficient

Complete the square


Rewrite as perfect squares

The vertex is the point (-1,4)
therefore
The range is 
I'm pretty sure he would be 5 ft 3 in. tall.
Answer:
1. (3^3 + 3^2)^2 actually equals (27 + 9)^2
which is the first mistake
2. (27 + 9)^2 does not equal (3^5)2, so (36)^2 does not equal 3^7
3. 3^7 DOES NOT EQUAL 21
Step-by-step explanation:
when you add powered numbers together, it does not multiply it, as your example:
1. (3^3 + 3^2)^2 actually equals (27 + 9)^2
which is the first mistake
2. (27 + 9)^2 does not equal (3^5)2, so (36)^2 does not equal 3^7
3. 3^7 DOES NOT EQUAL 21
