The circle is in A, so (-1, 4) coords
(x - xo)² + (y - yo)² = r²
(x - (-1))² + (y - 4)² = r²
(x + 1)² + (y - 4)² = r²
And the radius is the length of segment AC
distance of AC is






So r = 5
(x + 1)² + (y - 4)² = 5²
(x + 1)² + (y - 4)² = 25
Answer:
23/3 or 7 2/3 units ^3
Step-by-step explanation:
The formula for volume is
V = Bh where B is the area of the base and h is the height
V = 23/4 * 4/3
Rewriting
V = 23/3 *4/4
V = 23/3 units ^3
or if they want a mixed number
V = 7 2/3 units ^3
To make things easier, we can assume a value of x in order to substitute to each expression and obtain the side length of each. We can calculate for perimeter of each square. Then, compare them. We do as follows:
Assume x = 4
Square A
2x - 7 = 2(4) - 7 = 1
P = 4(1) = 4
Square B
-4x + 18 = -4(4) + 18 = 2
P = 4(2) = 8
Therefore, the perimeter of B is 2 than the perimeter of A.
Answer: jjjnknm,m
Step-by-step explanation:
So when you opened up the parenthesis on the right side of the question, you added -2 to 5 instead of multiplying. Since there is no addition sign in between -2 and the parenthesis, it should be multiplication, so -2x + -10.
So now the answer would be 10 = -10.
Which leads me to believe that this question wasn't written correctly because 10 does not equal -10 for sure.
