vodka [1.7K]
From information given, we know
208 miles was at rate of 65 mph. so divide total mileage by speed to get time spent.

208 ÷ 65 = 3.2 hours

So the rest of the trip took 6 - 3.2 = 2.8hours to travel another 348 total miles minus the 208 miles driven at 65mph is 140 miles.

140 miles divided by 2.8 hours gives speed

140 ÷ 2.8 = 50 miles per hour

A toy company has determined that the revenue generated by a particular toy is modeled by the following equation: 10x - 0.025x²
Digiron [165]

Answer:

Maximum revenue = 1000 thousands of dollars.

Explanation:

We have the revenue equation r(x)=10x - 0.025x^2, where x is measured in thousands of toys produced, and r(x) is measured in thousands of dollars.

At maximum revenue the derivative of equation is zero

So, r'(x)=0\\ \\10 - 0.025*2x=0\\ \\ x=10/0.05\\ \\ x=1000/5=200

So maximum revenue is when 200 thousands of toys are produced.

Maximum revenue, r(200)=10*200 - 0.025*200^2\\ \\ r(200)=1000

Maximum revenue = 1000 thousands of dollars.
