Answer:
Step-by-step explanation:
The formula for a circle of radius r centered at (h, k) is ...
(x -h)^2 +(y -k)^2 = r^2
Both of the given points are on the line y=-1. The distance between them is the difference of their x-coordinates, 2 -(-2) = 4. So, the radius of the circle is 4 and the equation becomes ...
(x -2)^2 +(y -(-1))^2 = 4^2
(x -2)^2 +(y +1)^2 = 16 . . . . . . . . . matches choice A
I'd say angle A = angle B
arc tangent (angle B) = 150 / 555

angle B = 15.124 degrees
By the way 555 feet is the height of the Washington Monument.

Answer:
The domain is (-∞,∞)
Step-by-step explanation:
Since there's no limit to this function, the values are infinity.
Answer:
the amount that should be worth in 25 years is $2,155,770
Step-by-step explanation:
The computation of the amount that should be worth in 25 years is shown below:
As we know that
Future value = Present value × (1 + rate of interest)^number of years
= $250,000 × (1 + 0.09)^25
= $250,000 × 1.09^25
= $2,155,770
Hence, the amount that should be worth in 25 years is $2,155,770
