X = 7 then make it an improper fraction which is 20/5 = 4
Answer:
The Cheetah's initial speed is 19.4 miles per hour
Step-by-step explanation:
Since the Cheetah is initially running and then gradually increases its speed by 50.6 miles per hour to reach a top speed of 70 miles per hour, let the Cheetah's initial speed be u.
Also, let the increase in the Cheetah's speed be Δu and let v be the Cheetah's final speed.
Now, the final speed, v = initial speed, u + change in speed, Δu
So, v = u + Δu
So, the Cheetah's initial speed is u = v - Δu
Now, v = 70 mi/h and Δu = 50.6 mi/h
Substituting v and Δu into the equation, we have
u = v - Δu
u = 70 mi/h - 50.6 mi/h
u = 19.4 mi/h
So, the Cheetah's initial speed is 19.4 miles per hour
Answer:
201.06
Step-by-step explanation:
Diameter: 12
12+4+4=20
R:10
Pi(10)^2
= 314.16
Subtract that from small circle
Pi(6)^2
=113.097
314.16-113.097
The answer is c…the slope is 2
