As shown in the question, the translation changes the points as follows:

$(x,y)\rightarrow(x+2,y-2)$

Therefore:

$\begin{gathered} C(-5,-1)\rightarrow C^{\prime}(-3,-3) \\ D(-4,3)\rightarrow D^{\prime}(-2,1) \\ E(-3,2)\rightarrow E^{\prime}(-1,0) \\ F(-2,0)\rightarrow F^{\prime}(0,-2) \end{gathered}$

Write the equation of the line in fully simplified slope-intercept form.

fiasKO [112]

$y = -\frac{1}{2}x - 1$

Step-by-step explanation:

Let's pick two points on the line: $P_1(-4, 1)$ and $P_2(2, -2).$ Let's calculate the slope of this line using these points:

$m = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{-2 - 1}{2 - (-4)} = -\dfrac{1}{2}$

With this value of the slope, we can write the general slope-intercept form of the equation as

$y = -\frac{1}{2}x + b$

To solve for the y-intercept b, let's use either P1 or P2. I'm going to use P2:

$-2 = -\frac{1}{2}(2) + b \Rightarrow b = -1$

Therefore, the slope-intercept form of the equation is

$y = -\frac{1}{2}x - 1$

A spherical water tank holds 7,500 ft3 of water. What is the diameter of the tank?

Alisiya [41]

Answer: 2r=d

d=24.28590063

Step-by-step explanation:

vsphere=4/3pir^3

7500=4/3pir^3

times both sides by 3

22500=4pir^3

divide both sides by 4

5625=pir^3

divide bot sides by pi

1790.4931=r^3

cube root both sides

12.142950=r

2r=d

d=24.28590063 ft
