A wheel with a radius of 7 inches is rotating at 4 revolutions per second. What is the linear speed v, in feet per second
1 answer:
Answer:
Linear speed= V= 175.84 m/s
Step-by-step explanation:
A wheel with a radius of 7 inches is rotating at 4 revolutions per second.
Linear speed v = rw
r= radius
r= 7 inches
w= angular speed
W= 4rev/s
But one rev= 2π
W= 4*(2π)/s
W= 8π/s
V= rw
V=7*8*3.14
V= 175.84 m/s

Answer:
A and C
Step-by-step explanation:
5) logx+log(x+9)=2
log(x(x+9))=2, log(x^2+9x)=2
6) log(x^2+9x)=2
(x^2+9x)=36 or 6^2
