You buy a package of cheese for $2.50, a loaf of bread for $2.15, a cucumber for $.65, and some tomatoes for $3.50. find the total cost of the groceries.

8.80

Step-by-step explanation:

2.5+2.15+0.65+3.50

8.80

Step-by-step explanation:

2.50+2.15+0.65+3.50=8.80

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.
