2. You throw a softball straight up into the air at a velocity of 30 feet per second. You release the softball at a height of 5.
nadya68 [22]

Answer:

-16t^2+30t+5.8

Step-by-step explanation:

We are given that

Initial velocity=30 ft/s

Initial position=s_0=5.8 ft

We have to write a mathematical model for height of the softball by using the position equation

The position equation on Earth's surface is given by

h(t)=-16t^2+v_0t+s_0

Where v_0= Initial velocity

s_0=Initial position

Substitute the values in the equation then, we get

h(t)=-16t^2+30t+5.8

Hence, the mathematical model for height of the softball is given by

-16t^2+30t+5.8

Find the measure of the indicated angle to the nearest degree
Alisiya [41]

Answer:

The answer to your question is below

Step-by-step explanation:

14) sin Ф = 32/33

    sin Ф = 0.9697

        Ф = 75.86°

15) sin Ф = 16/36

     sin Ф = 0.444

          Ф = 26.39°

16) sin Ф = 29/36

     sin Ф = 0.806

          Ф = 53.66°

17) cos Ф = 11/34

    cos Ф = 0.324

          Ф = 71.12°

18) sin Ф = 21/40

     sin Ф = 0.525

           Ф = 31.67°

19) cos Ф = 6/14

     cos Ф = 0.429

          Ф = 64.62°

20) cos Ф = 38/39

      cos Ф = 0.974

            Ф = 13°
