Not necessarily. Triangle ABC could be isosceles. Since the problem gives no further information about the third side, you cannot conclude definitely that ABC is equilateral.
I got V = X to the power of 5
-9.24 x 10^-5. Scientific notations requires the front number to be between 1-10 and when you move 5 places over, it becomes -9.24
Answer:
Step-by-step explanation:
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 />
