C. 16 feet.
Step-by-step explanation:
<u>How to find the maximum height of a projectile</u>
if α = 90°, then the formula simplifies to: hmax = h + V₀² / (2 * g) and the time of flight is the longest.
if α = 45°, then the equation may be written as:
if α = 0°, then vertical velocity is equal to 0 (Vy = 0), and that's the case of horizontal projectile motion.
Answer:
V=62.8
Step-by-step explanation:
3.14(2)^2(5)
3.14(4)(5)

Answer:
Choice A.
Step-by-step explanation:
tan < ABC = 60/40
So m < ABC = 56.31 degrees.
This makes m < DBC = 56.31 / 2 = 28.15 degrees
tan 28.15 = DC / 40
DC = 40 tan 28.15
= 21.407 ft.
Answer: fifty-two hundredths
Step-by-step explanation:
Answer:
The value of interest charged after 4 years = $ 960
Step-by-step explanation:
Principal amount P = $ 8000
Rate of interest R = 3 %
Time = 4 year
Simple interest = 
⇒ S.I. = 8000 × 4 × 
⇒ S.I. = $ 960
This is the value of interest after 4 years.
