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.

Answer:

5√5

Step-by-step explanation:

Use the distance formula:

d = √((x2 -x1)² +(y2 -y1)²)

d = √((-7-(-2))² +(-7-3)²) = √((-5)² +(-10)²) = √(25 +100)

d = √125 = √(25·5)

d = 5√5 . . . . distance between the points
