An equation of a circle:

(x - a)² + (y - b)² = r²

(a; b) - a coordinates of a center
r - a radius

r = 7; (3; -2) ⇒ a = 3 and b = -2

subtitute

(x - 3)² + (y - (-2))² = 7²

Answer: (x - 3)² + (y + 2)² = 49

10 POINTS + BRAINLIEST TO FIRST CORRECT ANSWER!!! THANK YOU!

Fofino [41]

Answer:

The answer is A (Look at the graph of the relationship. Find the y-value of the point that corresponds to x = 1. That value is the unit rate)

Step-by-step explanation:

Because the proportional relation is defined by k = $\frac{y}{x}$ . If ratio is $\frac{units}{1unit}$ then it is a rate. Unit rate means per 1 unit such as $\frac{amountofmoney}{1kg}$ or $\frac{km}{1hour}$ thus the correct answer is A.

a cylindrical well has a radius of 10 feet and a height of 15 feet what volume of water will it take to fill in the well

vampirchik [111]

Volume of water will it take to fill in the well is 4710 cubic feet

<h3><u>Solution:</u></h3>

Given that a cylindrical well has a radius of 10 feet

Height of cylindrical well = 15 feet

To find: volume of water will it take to fill in the well

Since, the well is in the form of cylinder, This means that we need to find the volume of cylindrical well

<em><u>The volume of cylinder is given as:</u></em>

$\text { Volume of water in the well }=\pi r^{2} h$

Where "r" is the radius and "h" is the height of cylinder

Substituting the given values we get,

$\begin{array}{l}{\text { Volume of water in the well }=(3.14) \times(10)^{2} \times(15)} \\\\ {=(3.14) \times(1500)=4710}\end{array}$

$\text { Volume of water in the well }=4710 \text { feet }^{3}$

Hence, the amount of water that can be stored in the well is 4710 cubic feet

Ok. So she wants to advertise that there are 100 different dolls available. If she adds another category, then at most she already had 99 different types. If I'm right (don't take my word for it) but the minimum she would have to have is one. <span />

Give the equation of the line through the point (14,6) with a slope of -9/7 in slope-intercept form

BigorU [14]

Answer:

Step-by-step explanation:

y - 6 = -9/7(x - 14)

y - 6 = -9/7x + 18

y = -9/7x + 24
