<h2>Equations of Circles</h2>
Generally, you'd see the equation of a circle organized in the following format:
is the center
is the radius
To determine the equation given the center and the radius:
- Plug both pieces of information into the general equation
- Simplify
<h2>Solving the Question</h2>
We're given:
- Radius: 99
- Center: (-1,-8)
Plug the radius and center into the equation as r and (h,k):
<h2>Answer</h2>
Answer:
*The bar is supposed to go on top of the number, but I will put it at the bottom because I don't know how to do it at the top*
a) 0.<u>5</u>
b) 0.<u>13456</u>
Step-by-step explanation:
a) The 5 is repeating so you put the bar on top of the 5
b) The number 13456 is repeated so you put the bar on top of the 13456
Answer:
Step-by-step explanation:
Because of the power of a power property, which states that 
, where m and n are real numbers, the expression you mentioned can be simplified by applying this property like this: 
David's total income is ($8/hr)x + ($11/hr)y.
This problem requires us to write and solve an inequality:
8x + 11(15)<$200
Solving for x: 8x < $200-$165, or 8x < $35. Strictly speaking, x = 4.375 hrs, but if we assume that David must work an integer # of hours, then x=5 full hours.
Answer:16
Step-by-step explanation:
Since she has 2 pizzas and she can get 8 silces from each it is 16 because 8x2=16
