Answer:
Equation of circle:
(x-10)² + (y+8)² = 36
Step-by-step explanation:
Given that,
Center of the circle is (10, -8)
and diameter = 12
We know that radius is half of the diameter.
So, radius (r) =
= 6
Now we have standard form of circle :
(x - h)² + (y - k)² = r²
Where (h,k) is the center of circle and r is the radius.
Now put the value of h, k and r in circle's equation
h =10
k = -8
r = 6
Equation of circle:
(x-10)² + (y+8)² = 36
That's the final answer.
I hope it will help you.
Answer:
okay
Step-by-step explanation:
Triangle QTR=~ triangle SRT
(2x^2/(1-x^2)) + 3^(1/x) for the first half you can simply divide all terms by the highest power of x to get:
2/(1/x^2-1) as x approaches infinity you have 2/-1=-2
For the second part the exponent approaches zero as x approaches infinity and anything raised to the zero power is equal to 1 so you have:
-2+1=-1
So the limit as x approaches infinity is -1.
