A baseball player hits a home run. A spectator observes the trajectory of the ball and expresses the height of the ball using the equation s(t)= -(t-15) + 225. Calculate the instantaneous velocity of the ball at t=4 seconds where the distance is measured in meters. A. 44 m/sec
B. 30 m/sec
C. 26 m/sec
D. 22 m/sec

The appropriate solution is Option D (22 m/sec).

Step-by-step explanation:

The given equation is:

Now,  

The instantaneous velocity at t = 4 will be:

=

=

=

=

Thus, the above is the correct option.

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
