Answer:
true
Step-by-step explanation: true
Answer:
Step-by-step explanation:
Simplifying
f(x) = 800(0.85) * x
Multiply f * x
fx = 800(0.85) * x
Multiply 800 * 0.85
fx = 680x
Solving
fx = 680x
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by 'x'.
f = 680
Simplifying
f = 680

Answer:
1024ft
Step-by-step explanation:
height of building = 624ft
h(t) = -16t^2 + 160t + 624
To find the, use -b/2a
a = -16, b = 160, c = 624
t = -160/ 2(-16)
t = -160 / -32
t = 5secs
The object will reach it's highest point after 5 seconds.
To find the highest point the object reaches, put t = 5 in h(t)
= -16(5)^2 + 160(5) + 624
= -16(25) + 800 + 624
= -400 + 800 + 624
= 400 + 624
= 1024ft
