Calculate the area of triangle abc with altitude cd, given a (6,0) b(1,5) c (2,0) and d (4,2)

What is the average rate of change for this function for the interval from x=2 to x=4 ?

The lengths of two sides of a right triangle are given. find the length of the third side. round to the nearest tenth if necessary. a) y = 12/5x + 39/5 b) y = 5/12x + 5/39 c) y = 12/5x - 39/5 d) y = 5/12x - 5/39

8.74 rounded to the nearest whole number
