Answer:
Center (h,k) = (4,7) and radius r = 7
Step-by-step explanation:
<u><em>Explanation</em></u>
Given that the equation of the circle
( x-4)² + (y-7)² = 49
( x-4)² + (y-7)² = 7²
Comparing the standard circle equation
(x-h)²+(y-k)² = r²
Center (h,k) = (4,7) and radius r = 7
2.9*10^10+ 5.35*10^10
= (2.9+ 5.35)*10^10 (distributive property)
= 8.25*10^10
The correct answer is A. <span>8.25 times 10^10~</span>
Since these are all like terms, you're essentially just adding and subtracting here.
Add and .
Then, subtract.
Your answer is .
We have the equation:
We have to find its roots with the quadratic formula:
Answer:
The roots (or solutions) of the equation are:
x1 = -8
x2 = 5
Answer:
15 1/12 feet
Step-by-step explanation:
Well if he descended 8 1/3 feet below the water, that means he must've went from board to water which is 6 3/4 feet then down 8 1/3 feet
6 3/4 + 8 1/3
= 6 9/12 + 8 4/12
=15 1/12 feet
