The area of triangle is 210 feet and the height is 30 feet write an equation to find the base of the triangle and use it to solve the problem

Equation:  0.5*30*b = 210

               Base length: 14

Step-by-step explanation: The formula of the area of a triangle is 1/2*b*h, so we can use that and the information given to make a formula then solve.

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.
