Use Newton's Law of Cooling to find the temperature of a substance as a function of time t in minutes that it has spent
cooling off. This relationship is given by, y = ae* +, where c is the temperature of the medium surrounding the cooling
object, a is the difference between the initial temperature of the object and the surrounding temperature, and k is a
constant related to the cooling object. Two samples of the substance were heated in a container of boiling water until their
initial temperatures were both 100° C. The first sample will be cooled by being left out at a room temperature of 24°C,
and the second sample of the substance will instead be cooled off in a refrigerator with an inside temperature of 4° C.
The value of a will equal the difference between each sample's initial temperature and that sample's surrounding
temperature, and the cooling constant of the substance is k = 0.12.

A sporting goods store has a sale on soccer balls: if you buy two soccer balls at the regular price, you get a third soccer ball for $1. Coach John bought 24 identical soccer balls during this sale for $136. What is the regular price for one of these soccer balls?
Answer:
The regular price of the balls is $8
Step-by-step explanation:
The sporting goods store sales promotion is as follows;
The price of the third ball after buying two balls at regular price = $1.00
The price of the number of balls Coach John pays for the balls he bought = $136
To buy 24 balls, we have;
2 + 1 + 2 + 1 + 2 + 1 + 2 + 1 + 2 + 1 + 2 + 1 + 2 + 1 + 2 + 1
Therefore;
The number of balls bought at regular price = The sum of the 2s = 16 balls
The number of balls bought for $1 = 24 - 16 = 8 balls
Let x represent the regular price of the balls, we have;
16 × x + 8 = 136
16·x = 138 - 8 = 128
x = 128/16 = 8
The regular price of the balls = x = $8.

The pattern of numbers below is an arithmetic sequence:
14, 24, 34, 44, 54, ...
Which statement describes the recursive function used to generate the sequence?
The common difference is 1, so the function is f(n + 1) = f(n) + 1 where f(1) = 14.
The common difference is 4, so the function is f(n + 1) = f(n) + 4 where f(1) = 10.
The common difference is 10, so the function is f(n + 1) = f(n) + 10 where f(1) = 14.
The common difference is 14, so the function is f(n + 1) = f(n) + 14 where f(1) = 10.
Answer:
The common difference is 4, so the function is f(n + 1) = f(n) + 4 where f(1) = 10.
Step-by-step explanation:
14 + 10 = 24
24 + 10 = 34
34 + 10 = 44
44 + 10 = 54
