Answer:
Average speed = 15
Step-by-step explanation:
To find the speed of the body, we can take the position equation and take the derivative in relation to time:
Speed = dY/dt = 2*3*t = 6t
Then, we need to find the speed at t=0 and the speed at t=5:
Speed(t=0) = 6*0 = 0
Speed(t=5) = 6*5 = 30
Now, we just need to make the average of both speeds:
Average = (0 + 30) / 2 = 15

Step-by-step explanation:
Answer:
The problem is with the arrangement of the ratios
PQ is the whole line but PR is a part of it only so you need QR to the ratio of PR
Answer:
The first step is Add 6 to both sides
Step-by-step explanation:
we have
Solve for x
That means ----> isolate the variable x
step 1
Adds 6 both sides
step 2
Multiply by 5/2 both sides
therefore
The first step is Add 6 to both sides
