Answer:
(x - 3)² + (y + 9)² = 25
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
Given area = 25π , that is
πr² = 25π ( divide both sides by π )
r² = 25 ( take the square root of both sides )
r = = 5
With centre (h, k) = (3, - 9 ) and r = 5 , then
(x - 3)² + (y - (- 9) )² = 5² , that is
(x - 3)² + (y + 9)² = 25

Answer:
C. 8√3/3
Step-by-step explanation:
It can be useful to remember that the ratio of sides in a 30°-60°-90° triangle are ...
1 : √3 : 2
That is the short leg is 1/√3 times the length of the longer leg.
8(1/√3) = 8(√3/3) . . . . . matches choice C
The answer is 340, not super good at math so dont know what scientific notation is but there you go
Answer:
First, I think the right formula is:
A) We first derive the formula given above:
V'(t) represent the drain rate of the tank volume.
B) the units is: gallons/time
C) at V'(10) = 100000/60 = 1666.66 gallons/time.
because the formula V'(t) is constant so it doesn't depend of time.
