Answer:
8.47 Hours
Step-by-step explanation:
The total distance covered in 12 hours with a speed of 60 mph
Distance = 12 x 60 = 720 miles
Now we are required to find the time taken if the same distance is travelled with a speed of 85 mph
Time = 8.47 hours
Answer:
Step-by-step explanation:a/
slope m = [f(x)-f(3)]/(x-3)
b/
tangent y - f(3) = [lim m ,as x-->3](x-3)
Answer:

Step-by-step explanation:
![\sf f(x) = 9x-10\\\\Put\ x = 8\\\\f(8) = 9(8) -10\\\\f(8) = 72-10\\\\f(8) = 62\\\\\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Csf%20f%28x%29%20%3D%209x-10%5C%5C%5C%5CPut%5C%20x%20%3D%208%5C%5C%5C%5Cf%288%29%20%3D%209%288%29%20-10%5C%5C%5C%5Cf%288%29%20%3D%2072-10%5C%5C%5C%5Cf%288%29%20%3D%2062%5C%5C%5C%5C%5Crule%5B225%5D%7B225%7D%7B2%7D)
