A car travel 35 miles on 3 gallons of gasoline. How many gallons of gasoline will the car need to travel 150 miles?

12.857

Step-by-step explanation:

. you divide 3 by 35 in order to find out how many gallons are used in a mile

. then multiply the number you get by 150 because the number you get is equal to 1 mile and u are finding for 150 miles

. lastly you round your answer (optional) ( i rounded to 3 dp's)

i think 5 miles per hour

step-by-step explanation:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
