Answer:

The Ruiz family's laptop has the greater initial resale value.

During the first four years, the resale value of the Sawyer family's laptop decreases at an average rate faster than the resale value of the Ruiz family's laptop.

Explanation: I just took the Edmentum test on this

Also: If you multiply the 620 (the initial resale value of the Sawyer family's laptop)  and multiply it by 0.85 once, you'll get the value of week 1. Take that total and multiply it by 0.85, you'll get the value of week 2.

Like this: 620 x 0.85 = 527 (week 1)

                527 x 0.85 = 447 (week 2)

                447 x 0.85 = 379 (week 3)

                379 x 0.85 = 322 (week 4)

miss Akunina [59]

Answer:

f(t) = -0.05t +12

Step-by-step explanation:

To solve this problem we must pay attention to the following data supplied:

- f It is the number of figurines that remain to be painted.

- t amount of time, in minutes, that Colin spends painting

- Colin takes 20 minutes painting each figurines.

- After painting 60 min, he still has 9 figurines left. f (60) = 9

If he takes 20 minutes painting 1, it means that in 60 minutes he has painted 3 and he has 9 left.

Then, at the beginning he has 9 +3 figurines to be painted.

f (0) = 3 + 9\\f (0) = 12

With these two points we can find the function:

If m is the slope of the line, then:

m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{9-12}{60-0}\\\\m = -0.05\\\\f (t) = -0.05t + c

Where by definition c = f(0) = 12

Finally the formula is:

f(t) = -0.05t +12
