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
I think it's c I'm not too sure
Answer:
The 3rd one 2.15
Step-by-step explanation:
12.35 in whole
1.25 x 3 = 3.75
12.35-3.75= 8.60
![\sqrt[4]{8.60}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B8.60%7D)
= 2.15

1: 1.19 for 67.2 ounces is about 1.77 cents per ounce. However, $1.50 for 72 ounces is about 2.08 cents per ounce. Clearly, then, the first bottle is cheaper.
2. We simply divide 3/4 by 2 to get (3/4)/2=3/(4*2)=3/8.
3. If the length of the second is 20 feet compared to a 2-foot length for the first, the width of the second rectangle will be ten times the width of the first, so the width of the second rectangle is 10*8=80.
