Help please, detailed explanation would be nice too if possible

Step-by-step explanation:

The average rate of change on an interval is given by the rise on the interval divided by the run (the width of the interval). Here, the end points are ...

  (5, -3) and (8, 0)

The rise is 0-(-3) = 3. The run is 8 -5 = 3. The ratio of rise to run is 3/3 = 1.

The average rate of change on [5, 8] is 1.

b) 1

Step-by-step explanation:

hope it's helpful

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.

step-by-step explanation:

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
