Unfortunately your response would only be true if CD was perpendicular to AB. However we don't know if CD is perpendicular or not. So we don't have enough information. The actual answer is choice E) None of these.
Step-by-step explanation:
you don't know how exponents work ?
the exponent simply says how often the base value has to be multiplied by itself.
e.g. 5³ = 5×5×5 = 125
and when it says x=2, then you need to put 2 at every location, where is says "x".
so,
x⁵ for x = 2 means 2⁵ = 32
8² = 64
2⁴ = 16
Answer
y=5/2x-7/6
Step-by-step explanation:
The rocket will take a time of approximately 2.686 seconds to hit the ground.
<h3>How much time does a rocket need to hit the ground?</h3>
The height of the rocket (h), in feet, is modelled by a quadratic equation, which is used to model free fall motion, that is, the motion of an object solely due to action of gravity. In this problem we must look for the time when the rocket hits the ground:
- 16 · t² + 40 · t + 8 = 0
(t - 2.686) · (t + 0.186) = 0
Only the first root offers a realistic solution, for time is a non-negative variable. The rocket will take a time of approximately 2.686 seconds to hit the ground.

Complementary angles are two angles whose sum adds up to 90 degrees
Za + Zb = 90
You know Za measures 59
59 + Zb = 90
Solution: Zb is 31 degrees
