It is 56680 square feet.
Step-by-step explanation:
Multiply the two numbers
Both lines AB and CD are secant lines beacuse in two points they are touching the circunference. There is a Theorem which says the following
Since the distance from the center of the circle to each secant line is the same (5 units), we could assume that the both secant lines are similar. saying:
Then the lenght of CD is:
Answer: C. x-2
Step-by-step explanation:
We have the following expression:
Factoring in the numerator:
Factoring again in the numerator with common factor :
Simplifying:
Hence, the correct option is C. x-2
Answer:
( x +2)² + ( y - 4)² = 81
Step-by-step explanation:
The equation for a circle in standard form is ( x – h)² + ( y - k)² = r², where the center is (h, k) and the radius is r.
Putting the question's given information into the formula gives you
[ x – (-2)]² + ( y - 4)² = (9)²
( x + 2)² + ( y - 4)² = 81
Answer:
-4x^2 -2x+6
Step-by-step explanation:
2x^2+(4x-6x^2)+9-(6x+3)
Distribute the minus sign
2x^2+4x-6x^2+9-6x-3
Combine like terms
2x^2 -6x^2 +4x -6x +9-3
-4x^2 -2x+6
