To the nearest tenth, find the perimeter of triangle abc with vertices a(3, 2), b(-2, 3), and c(2, 6)

14.2 units

Step-by-step explanation:

To find the distance between the points, you use the formula

 Therefore, we need to get the distances between points A and B, between points B and C and between points A and C.

Perimeter==14.2 units (to the nearest tenth)

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

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.
