Question 1:
The airline cost for x passengers, measured in thousands of passengers, to travel round trip from New York to Atlanta is given by: C(x)=square root 0.3x+1 where C(x)is measured in millions of dollars and x greater than or equal to zero
Find the airline's cost for 10,000 passengers (remember, that would NOT be 10,000) to travel from New York to Atlanta. Use the equation editor to show all work. Write a sentence to explain your answer.
QUESTION 2:
If the airline charges $320 per passenger, find the profit made by the airline for flying 10,000 passengers from New York to Atlanta. Use the equation editor to show all work. Write a sentence to explain your answer. Remember: Profit = Revenue - Cost
QUESTION 3:
Approximate the number of passengers who traveled from New York to Atlanta if the total cost for the airline was $4 million. Use the equation editor to show all work. Write a sentence to explain your answer.
QUESTION 4:
The volume of a rectangular box is 64 ft3. If the width is 3 times longer than the height, and the length is 9 times longer than the height, find the dimensions of the box. Define your variables then show all work using the equation editor. Write a sentence that explains your answer
QUESTION 5:
A model rocket is launched straight upward from the side of a 212-ft cliff. The initial velocity is 86 ft/sec. The height of the rocketh(t) is givenby: h(t)=-16t2 + 86t + 212
whereh(t) is measured in feet andtis the time in seconds. Use the quadratic formula to find the times (t)at which the rocket is 320 ft.above the ground. Round your answers to the nearest hundredth of a second.
QUESTION 6:
Steve and Tammy leave a campground, hiking on two different trails. Steve heads south and Tammy heads east. By lunchtime they are 8 mi apart.
Tammy walked 4 miles more than Steve. Find the distance each person hiked. Use completing the square to find your answer rounded to the nearest tenth of a mile.
