Solve for the acceleration, a, in terms of the other variables. For this assessment item, you can use ^ to show exponents and type your answer in the answer box, or you may choose to write your answer on paper and upload it. In physics, if a moving object has a starting position at (s0), an initial velocity of (v0), and a constant acceleration (a), then the position S at any time (t>0) is given by: S = ½ at^2 + v0t + s0

S- v0t - s0 = ½ at^2 2 (S - v0t - s0)/ t^2 (S - v0t - s0) (2 + t^2) = a

A business traveler rents a car for $75 a day, and $0.50 for each mile. If the trip will last 3 days and the traveler can spend no more than $400, how many miles can be driven? Explain your reasoning and express the formula as an inequality.

The rental cost for 3 days is 75 • 3 = $225. Then, the cost for the miles is 0.50 m. The total cost is 225 + 0.5 m. The inequality is: 225 + 0.5 m ≤ 400, and m ≤ 350 miles.
