In a class in which the final course grade depends entirely on the average of four equally weighted 100-point tests, Gloria has scored 95, 90, and 92 on the first three. What range of scores on the fourth test will give Gloria a B for the semester (an average between 80 and 89, inclusive)? Assume that all test scores have a non-negative value. Express your answer in interval notation.

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.

step-by-step explanation:

you put them as all the same denominator and multiply

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
