What is the slope of the secant line? Thank you
Burka [1]

Answer:

Given that,

The function is,

f(x)=1.2x^3-37x^2+265x+555

To find: To find the slope of the secant line from x1=0 and x2=4

Explanation:

First we find the corresponding y values that is y1 and y2 for the given x1 and x2 respectively.

we get,

Whwn x1=0,

y1=f(x1)=f(0)

f(0)=1.2(0)^3-37(0)^2+265(0)+555f(0)=555y1=555

When x2=4, we get,

f(4)=1.2(4)^3-37(4)^2+265(4)+555f(4)=1099.8

To find the slope of the line passing the points (0,555), (4,1099.8)

we know that,

Slope of the line passing through the points (x1,y1) and (x2,y2)

m=\frac{y2-y1}{x2-x1}

we get,

m=\frac{1099.8-555}{4-0}m=\frac{544.8}{4}m=136.2

Answer is:

Slope of the secant line from x1=0 and x2=4 is 136.2.

1/5 = 0.2

14/20 = 0.7

24/50 = 0.48

1/2 = 0.5

8/25 = 0.32

4/10 = 0.4

17/20 = 0.85

6 x 4/8 = 3

6 x 4/12 = 2

8 x 18/8 = 18
