Jennifer hit a golf ball from the ground, and it followed the projectile h(t)=-16t^2+100, where t is the time in seconds, and h is the height of the ball

Step-by-step explanation:

The complete exercise is: "Jennifer hit a golf ball from the ground and its movement follows the equation , where t is the time in seconds, and h(t) is the height of the ball at a given time "t". Find the time that it took the golf ball to hit the ground."

The quadratic function is:

Since the ground is at , you need to substitute this into the function:

Now you must solve for "t". The steps are:

- You need to subtract 100 from both sides:

- Now you must divide both sides of the equation by -16:

- Applying the square root both sides of the equation, you get:

answer: a. 74

step-by-step explanation:

it shows divided evenly, so add the 37+37 = 74
