Answer:
725/50= 14.5
14.5 hours is your answer
i think
0+a+b
a=2
b=10
0+2+10=12/3=4
4=2a
5a is the answer.
We do the midpoint formula to find the center of the circle to get the left side of the equation.
Midpoint = [(X₁ + X₂) / 2 , (Y₁ + Y₂) / 2]
Now plug in:
[(8 + 4) / 2 , (- 6 - 2) / 2]
(12 / 2 , - 8 / 2)
(6, - 4)
The center of the circle is (6, -4)
Now we plug it into the equation of a circle:
(x - h)² + (y - k)² = r² where (h, k) is the center of the circle and r is the radius.
(x - 6)² + (y + 4)² = r² is the left side of the equation. This will eliminate options A and C
Now we do the distance formula using the center and an endpoint to get the radius. The formula for distance is:
√((X₂ - X₁)² + (Y₂ - Y₁)²)
We plug in using either of the endpoints.
√((4 - 6)² + (- 2 - (- 4))²)
√((-2)² + 2²)
√(4 + 4)
√8
√8 is your radius
(√8)² = 8
Your correct answer is (x - 6)² + (y + 4)² = 8, Option D
Answer:
14
Step-by-step explanation:
- multiply the parenthesis by 1/4
- multiply both sides by 12
- move terms
- collect the like terms calculate
- change the signs
The answer is <span>-6(m2 - 3m + 6)
</span>
-6m2 + 18m - 36 = - (6m2 - 18m + 36)
= - (6m2 - 6*3m + 6*6)
= -6(m2 - 3m +6)
