aksik [14]

If the order of the numbers in the question are the order Darrin put theem in then no, his work is not correct. this is because 7.25 is not greater than 7.52. the real order should be 7.52,7.25, 5.72, 5.27

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

$-16t^2+30t+5.8$
