Two trains leave the station at the same time, one heading west and the other east. The westbound train travels at 90 miles per hour. The eastbound train travels at 70 miles per hour. How long will it take for the two trains to be 448 miles apart? Do not do any rounding.

[] hours

homozygous. one is homozygous, while two is heterozygous.

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.

hope this is what you were asking for!
