Answer:

(x + 1)^2 + (y - 4)^2 = 8

Step-by-step explanation:

Midpoint of the diameter is the centre

So....Centre coordinates are ((-3+1)÷2 ; (2+6)÷2) = (-1;4)

Calculate the radius of the circle....

Radius = square root of [(-1+3)^2 + (4-2)^2]

;Radius = square root of 8

Then substitute the x-coordinate of the centre into the first slot....then the y-coordinate into the second slot and the radius(squared) into last slot of the equation......;

(x + 1)^2 + (y - 4)^2 = 8

Which of the following statements must be true based on the diagram below? Select

pentagon [3]

The question is an illustration of equivalent ratios and similar triangles.

The true option is: $\frac{WU}{WV} = \frac{UR}{VS}$

From the diagram, we have:

$WU = UR$ ---- This is so because both lines are marked once

Also, we have:

$WV = VS$ ---- This is so because both lines are marked twice

Divide both equations

$\frac{WU}{WV} = \frac{UR}{VS}$

Hence, the true option is: $\frac{WU}{WV} = \frac{UR}{VS}$

HELP PLEASE, Part a of the question was posted earlier on.

$\bf \lim\limits_{x\to 6}~\cfrac{x^2+x+42}{x-6}\implies \lim\limits_{x\to 6}~\cfrac{(x+7)(x-6)}{(x-6)}\implies \lim\limits_{x\to 6}~x+7
\\\\\\
\lim\limits_{x\to 6}~(6)+7=13
\\\\\\
\textit{since the original equation holds for all, }x\ne 6,\textit{ then it approaches}\\
\textit{the same limit as }x+7$

Answer:

area = pi*24^2/4 = 452 yd^2

so that means you will need 452/59 = 7.6 (or 8) gallons
