The radius of the circle would be 10.19 I hope this helped!! :)
Answer:
5ft
Step-by-step explanation:
all sides of a square are equal and there are 4 sides so divide 20 by 4 and you get 5 ft
Answer:
Thus we find that velocity vector at time t is
(5t+15, 5t^2/2, 4t^2)
Step-by-step explanation:
given that acceleration vector is a funciton of time and at time t

v(t) can be obtained by integrating a(t)
v(t) = 
Thus we use the fact that acceleration is derivative of velocity and velocity is antiderivative of acceleration.
The arbitary constant normally used for integration C is here C vector = initial velocity (u0,v0,w0)
Position vector can be obtained by integrating v(t)
Thus we find that velocity vector at time t is
(5t+15, 5t^2/2, 4t^2)
To find A' they used the rule of multiplication, which is:
the derivative of a product of two terms is the first term times the derivative of the second term plus the second term times the derivative of the first.
To find b' they just isolated b'
(5x-12)^2
Square factor of 25 is 5.
Square factor of 144 is 12.
Hope this helps. I didn't understand what to do with it.
