Im confused could you explain what the questions are better.
49^2 or 7 I just know from 6th grade
Answer:
Yes, see below.
Step-by-step explanation:
Convert the equation to vertex form to find the maximum height:
h = -16t2 + 64t + 5
= -16(t^2 - 4t) + 5
= -16 [(t - 2)^2 - 4] + 5
= -16( t - 2)^2 + 64 + 6
= -16(t - 2)^2 + 69.
So the maximum height the rock reaches is 69 feet.
This height is reached at 2 time seconds.
Answer:
for Part A
Answer is C.
Step-by-step explanation:

Here the angle, a is 60°, Opposite is 20 and adjacent is x.
Therefore we have,

Making x the subject gives us

Part B
Value of x to the nearest tenth
