Answer: 50.24
Area of a circle is pi times r^2
The r is 1/2 the d
So 8/2 = 4
Pi times 4^2= 50.24
Answer:
A
Step-by-step explanation:
Discriminant= 8^2-4(16)(1)
=0
8 times 3 equals 23 and that is one of the answers
You can use the formula to solve for the y-values in the table. Insert the x-value into the equation: y = 2x - 2
(ex. y = 2(1)-2)
So..
x | y
0 | -2
1 | 0
3 | 4
5 | 8
8 | 14
10 | 18

A number=x
2x/6=42
2x=252 by multiplying both sides by 6
x=126 by dividing both sides by 2 to isolate the variable
