Find the center and radius of this

ipn [44]

$\text{Hello there! :)}$

Answer:

$\boxed{\text{Center at } (7, -4), \text{ Radius of } 7.}$

$\text{Formula for a circle: } (x - h)^{2} + (y - k)^{2} = r^{2} \text{ Where:}$

$h = \text{ x-coordinate of center}\\\\k = \text{ y-coordinate of center}\\\\r = \text{ radius}\\\\\text{Therefore:}$

$\text{In the equation } (x - 7)^{2} + (y + 4)^{2} = 49:$

$h = 7\\\\k = -4\\\\r = \sqrt[]{49} = 7 \\\\\text{So:}$

$\text{Center at } (7, -4), \text{ Radius of } 7.$

A rectangles length is 1.5 times its width. The perimeter of the rectangle is four more than 3 times the length. What are the di

vovikov84 [41]

Answer:

8 by 12 units

Step-by-step explanation:

Let w represent the width of the rectangle. Then the length is 1.5w. The perimeter is 4 more than 3 times this, so is (3(1.5w) +4) = 4.5w+4

The perimeter is given by the formula ...

P = 2(length + width)

Filling in the given values for the variables, we have ...

4.5w +4 = 2(w +1.5w)

4 = 0.5w . . . . . . subtract 4.5w and collect terms

8 = w . . . . . . . . . multiply by 2

length = 1.5×8 = 12

The rectangle is 8 units wide and 12 units long. The perimeter is 40 units.
