A circle has its center at (-1, 2) and a radius of 3 units. What is the equation of the circle? (1 point) (x - 1)2 + (y + 2)2 =

Nina [5.8K]

Answer:

(x + 1)^2 + (y - 2)^2 = 3^2 = 9

Step-by-step explanation:

The standard equation of a circle with center at (h, k) and radius r is

(x - h)^2 + (y - k)^2 = r^2.

Here, h = -1, k = 2 and r = 3, so the equation of this particular circle is

(x + 1)^2 + (y - 2)^2 = 3^2 = 9.

Coyne Corporation is evaluating a capital investment opportunity. This project would require an initial investment of $36,000 t

Zarrin [17]

Answer:

$27,643

Step-by-step explanation:

The net present value is the present value of after tax cash flows from an investment less the amount invested.

The formula for the NPV can be found in the attached image.

The NPV can be found using a financial calculator:

The cash flow for year zero = $-36,000

Cash flow from year one to three = $19,000

Cash flow for year four =$19,000 + $5,000 = $24,000

I = 10%

NPV = $27,643
