Answer:

-4

Step-by-step explanation:

The average rate of change of the interval [a,b] is (f(b)−f(a)) / (b−a)

Replacing a=−5, b=4, f(x)=−x^2−5x+12.

(f(b)−f(a))/(b−a) =12−5x4− 4^2 − (12−5 x(−5)−(−5)^2)/ (4−(−5))= −4.

how much it weighs: if a ball weighs 1 oz it'll bounce higher

its size: if a ball is small and light it will most likely bounce higher but if its large and heavy it probably wont bounce as high.

Obtuse Triangle: the triangle has an angle greater than 90 degrees

Equilateral Triangle: all sides are the same length

Right Triangle: the triangle has a 90 degree angle

Scalene Triangle: none of the lengths are equal to each other
