Kevin recorded the temperature of a mixture at the beginning of a science experiment, and then he recorded the temperature three more times. Each time the temperature dropped 5°F. The final temperature was -7°F. What was the temperature of the mixture when Kevin started the experiment?

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.

2,160 π

step-by-step explanation:

d 600 because 15*10*2=300

300+300=600
