Answer:
b
Step-by-step explanation:
no explanation need because it started in MNO
A) Linear velocity, v = ωr ω = Angular velocity, r = radius.
<span>ω = 5 revolutions per minute. 1 minute = (1/60) hour. </span>
<span>= 5*2π radians / (1/60) hour = 600π radians per hour π = 3.14 </span>
= 600*3.14 = 1884 radians / hour
<span>but radius, r = 10 feet, 5280 feet = 1 mile, 10 feet = (10/5280) mile </span>
Linear velocity, v = ωr
<span> v = 1884 radians / hour * (10/5280) mile </span>
v ≈ 3.568 miles / hour<span />
Answer:
1. It has a Maximum value
2. (−3,2)
3. 2

Answer: 50.24
Step-by-step explanation:
area of a quarter circle = area of the whole circle divided by 4
a = 3.14(8)² = 200.96
200.96/4 = 50.24
