Answer:
<u>answer is C ( </u>
<u> )</u>
Step-by-step explanation:
so here is how you do it.
first you need to find out what 
is
which is the same as 3 X 3 X 3 X 3 X 3 X 3 X 3 X 3
the answer to that is 6,561
then you have to square root that
which looks like this
which is 81
which means that you have to find the same expression that equals to 81
I then did (C) to see if the answer will be 81 and it is. so your answer is C
Answer: NO
Step-by-step explanation:
The functions that models the height of the ball is given as
h(t) = -5t2 + 40t + 100
Where
a = -5, b = 40, c = 100
The time the ball will reach the maximum height will be the vertex of the parabola. At the line of symmetry, the time t will be:
t = -b/2a
Substitute b and a into the formula above.
t = - 40 / -5 = 8
Substitute 8 for t in the function f(t)
h(t) = - 5(8)^2 + 40(8) + 100
h(t) = -5(64) + 40(8) + 100
Open the bracket
h(t) = -320 + 320 + 100
h(t) = 100
The maximum height of the ball is 100m
Given that the power lines is 185 metres above the ground. The golf ball will therefore not hit power lines because the maximum height the ball can go is 100 metres
