xz_007 [3.2K]

Answer:

x^2 + y^2 = 100

Step-by-step explanation:

The general form of the equation of a circle is

(x-h)^2+(y-k)^2 = r^2

where (h,k) is the center and r is the radius

(x-0)^2+ (y-0)^2 = 10^2

Nuetrik [128]

Answer: v= 56 ft per second


Step-by-step explanation:

Given: A quarterback throws a football to a teammate.

Projectile motion formula is given by :-

h(t)=-16t^2+vt+h_0, where h_0=6.5

Now, to find  v at h=5 and t=3.5, substitute these values in the above equations, we get

5=-16(3.5)^2+v(3.5)+6.5\\\Rightarrow5=-16(12.25)+3.5v+6.5\\\Rightarrow5=-196+6.5+3.5v\\\Rightarrow\ 5=-189.5+3.5v\\\Rightarrow\ 3.5v=5+189.5\\\Rightarrow\ 3.5v=194.5\\\Rightarrow\ v=55.57142\approx56
