If the cost is a function depending in the number of sections, how much will 200 sections cost? a. 7,400 b. 7,439 c. 7,556 d. 7,837

So here we have a function F(x) = y. and you give some of the points (x,y).

this are (10, 409) , (50, 1889) , (125, 4664)

then, if we assume a linear relationship, we could find the slope using the next formula:  

then for the first two points we get:

and the slope between the second and third point is:

So we have the same slope in the two segments, and it's safe to assume that our function is linear. Now we need to find the x-intercept

then F(x) = 37x + b

and F(10) = 370 + b = 409

b = 409 - 370 = 39

So our function is F(x) = 37*x + 39

then if x = 200, F(200) = 37*200 + 39 = 7439.

So the correct answer is B.

a=r

d=q

c=p

b=s

hope this !

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
