Answer:

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

Step-by-step explanation:

Equation for a circle: (x – h)^2 + (y – k)^2 = r^2

Step 1: Determine what h, k, and r are

h is the x value of the point: -3

k is the y value of the point: 2

r is the radius of the circle: 3

Step 2: Plug in and solve

(x – h)^2 + (y – k)^2 = r^2

(x – (-3))^2 + (y – (2))^2 = (3)^2

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

Answer: (x + 3)^2 + (y - 2)^2 = 9

If $25, 000 is invested into an account paying 4.5% per year, compounded quarterly, how much money can be withdrawn from the acc

pogonyaev

The money can be withdrawn from the account every two months for the next 6 years is $20, 625, 000

<h3>What is compound interest?</h3>

The formula for compound interest is given as;

$A = P ( 1 + \frac{r}{n} )^n^t$

P = principal interest = $25, 000

r = rate = 4. 5%

n = 2 months

t = 6 years

A = $25, 000 ( 1 + \frac{4. 5}{2} )^2 ^*^6$

A = $25, 000(1 + 0. 75)^1^2$

A = $25, 000( 825. 00)$

A = $20, 625, 000

Thus, the money can be withdrawn from the account every two months for the next 6 years is $20, 625, 000

Is 15/28 equivalent to 25/45

Lana71 [14]

No, it's not.

15/28 equals to (about) 0.54 while 25/45 is (about) 0.56.
They are close, but not equivalent.

An end point of a line segment is (-10, -2) and the midpoint of the line segment is (0,4). Find the other endpoint.

Dovator [93]

Answer: The other endpoint is (10,10)

Step-by-step explanation:

$\frac{-10 + x }{2} =0$

-10 +x = 0

+10 +10

x= 10

$\frac{-2 + y}{2} =4$

-2 + y = 8

+2 +2

y =10

Benito spent $1837 to operate his car last year. Some of these expenses are listed on the table below:

Dmitry_Shevchenko [17]

Answer:

$0.085 per mile or 8.5 cent per mile

Step-by-step explanation:

We know:

Total expenses = $1837

Gasoline expense = Total expenses - other expenses

= 1837 - 972 - 114 - 105 = $646

Benito drove in total of: 7600 miles

Cost of gasoline per mile = Money spent for gasoline / total miles

= $646 / 7600

= $0.085 per mile or 8.5 cent per mile

Hope this helped :3
