Nookie1986 [14]

Answer:

In Point Slope Form: y+6=4(x-1)

Step-by-step explanation:

<u>First you have to find the points given which are:</u>

  • (1, -6) and (4, 6)

<u>Label the points x1, y1, x2, and y2</u>

  • It already gives you the slope which is 4.

<u>Plot the points in the equation of Point Slope Form:</u>

<em><u>y1-y2=m(x-x1)</u></em>

  • y1-6=4(x-1)

<u>Simplify: y1-6=4x-4</u>

  • y=4x+2

<u>It doesn't ask you to simplify but why not!  </u>

konstantin123 [22]

Answer:

$13.10 represents the rate of change

Step-by-step explanation:

13.1 is the only value in the equation with a variable (g). There is an additional $13.10 charge for every gigabyte used over the limit, and this is the rate of change.

For example, if 5 gigabytes were used over the limit, the charge would be 13.1(5) or $65.50

trapecia [35]

Answer: 3.7 in.

Step-by-step explanation:

Given,   A toy designer is creating a basketball plushy. The designer has fabric that measures 171.9 sq. in.

To find: The maximum radius of the basketball that the designer can create.

For this, Surface area of basketball = area of fabric

Formula: Surface area of sphere = 4\pi r^2, where r is the radius.

Then, 4\pi r^2=171.9

r^2=\dfrac{171.9}{4\pi}=\dfrac{171.9}{4\times3.14}\\\\\Rightarrow\ r=13.6863057325\\\\\Rightarrow\ r=\sqrt{13.6863057325}=3.69950074098\approx3.7

Hence, the maximum radius of the basketball that the designer can create is 3.7 in.
