Answer:
idk refrace your question
Step-by-step explanation:
The domain of the function is \[A \ge0\] If A is negative we get an imaginary number for the radius. This makes sense because the area of a circle cannot be negative.
Answer:
A
Step-by-step explanation:
Its basically whatever point(s) meet exactly the on the x axis
Answer:
Each small candleholder holds 3 candles, and each large one holds 5 candles.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of candles that a small candleholder holds.
y is the number of candles that a large candleholder holds.
24 small candle holders and 3 large candle holders, using a total of 87 candles.
This means that

Simplifying by 3


14 small candle holders and 7 large candle holders, for a total of 77 candles.
This means that 
Simplifying by 7


Since 





Each small candleholder holds 3 candles, and each large one holds 5 candles.
1. vertical angle theorem and triangle angle sum theorem
2. The sum of the interior angles of a triangle = 180
so < x = 180 - (70 + 30) = 180 - 100 = 80
and < y is a vertical angle to < x...and vertical angles are equal..
so < y = 80
