Ahighway engineer wants to estimate the maximum number of cars that can safely travel on a particular road at a given speed. she assumes that each car is 14 feet long, travels at speed s, and follows the car in front of it at a safe distance for that speed. she finds that the number n of cars that can pass a given spot per minute is modeled by the function n(s)=86s14+14(s17)2 at what speed can the greatest number of cars travel safely on that road?
the numbers go up by twelve each time, witch if you add up enough times you will get to 52 and 64
answer:x = 1000
the measure of the exterior angle a is the sum of the opposite angles inside the triangle.
angle a = 90+ 32
it is 15
the prime numbers 5 and 3 are both factors that are common to 30 and 75. thus, the “greatest common factor” of 30 and 75 is 15.
