Alyssa works for Thomas Edison electrical company. She earns $100 for going to a customer's house and 65 per hour, h, for the job. this is model by 65H + 100. Evaluate for H =3 to find how much Alyssa will earn for a job that takes 3 hours.

Answer 1

To evaluate for H = 3, we replace H with 3 in the expression 65H + 100:

65(3) + 100 = 195 + 100 = $295

Therefore, Alyssa will earn $295 for a job that takes 3 hours.

Answer 2

A competitive cliff diver jump from a height of 75 ft. Find the number of feet the diver is above the ocean in 2 seconds. Evaluate for t=2 by using the formula 75 - 16t2, where t is time in seconds.

Answer 3

To evaluate for t = 2, we replace t with 2 in the expression 75 - 16t^2:

75 - 16(2)^2 = 75 - 16(4) = 75 - 64 = 11

Therefore, the diver is 11 feet above the ocean after 2 seconds.
