A.)Which two points should you use to find the equation of the model? Explain.

ikadub [295]

Part a)

we know that

to find the equation of the line, I will use the two points that are closest to the line

Let

A(1,14)

B(7,7)

Part b)

Find the slope

we know that

the formula to find the slope between two points is equal to

$m=(y2-y1)/(x2-x1)$

substitute

$m=(7-14)/(7-1)$

$m=(-7)/(6)$

$m=-7/6=-1.167$

the answer part b) is

the slope is $m=-7/6=-1.167$

Part c)

we know that

the equation of the line in point slope form is equal to

$y-y1=m(x-x1)$

use the point B (7,7)

$y-7=(-7/6)*(x-7)$

therefore

the answer part c) is

$y-7=(-7/6)*(x-7)$

Part d)

we know that

the equation of the line in slope-intercept for is equal to

$y=mx+b$

we have

$y-7=(-7/6)*(x-7)$

$y=(-7/6)x+(49/6)+7$

$y=(-7/6)x+(91/6)$

therefore

the answer Part d) is

$y=(-7/6)x+(91/6)$ or $y=-1.167x+15.167$

Tell me whether an object’s surface area has increased or decreased if the size of the object is changed by a factor of 1/3???

ANTONII [103]

The surface area should decrease since the volume of the object is 33% of the original. This means that it will have less area on the surface.
