Answer:
The letter "i" is used to signify that a number is an imaginary number.
Step-by-step explanation:
An imaginary number is one that gives a negative result when squared. This differs from when you square real numbers where you always get a positive result. For example:
i = √-1
Imaginary numbers can be especially useful when trying to find the square root of a real negative number such as -16. Normally we cannot find the square root of -16 but through the use of imaginary numbers we can:
√-16 = 4i

Answer:
Step-by-step explanation:
Area = L x W gym area is (5x + 5x) ft² if W = 5x Find the L
Area = L x W divide both sides by W
Area/W = (L x W) / W
Area/W = L = Area/W
L = Area/W
= (5x + 5x) / (5x)
= 5x( 1 + 1) / 5x
= 5x(2) / 5x the 5x's cancel each other 5x/5x = 1
= 2 ft I got 2. I suspect the 12 was a typo and should have been 2
Answer:
(x + 3)^2 + (y - 2)^2 = 9
Step-by-step explanation:
<u>Equation for a circle: (x – h)^2 + (y – k)^2 = r^2</u>
<u />
<u>Step 1: Determine what h, k, and r are</u>
<em>h is the x value of the point: -3</em>
<em>k is the y value of the point: 2</em>
<em>r is the radius of the circle: 3</em>
<u>Step 2: Plug in and solve</u>
(x – h)^2 + (y – k)^2 = r^2
(x – (-3))^2 + (y – (2))^2 = (3)^2
<em>(x + 3)^2 + (y - 2)^2 = 9</em>
<em />
Answer: (x + 3)^2 + (y - 2)^2 = 9
Answer:
13x + 7 = 5x - 20
Step-by-step explanation:
SOLVE for X
13x + 7 = 5x - 20
-------------------------
-5x -7
------------------------
8x=-27
x= -3.375 or -27/8
