Find the equation (in standard form) whose center is (5, -3) and goes through (2, 5).

1 answer:

3 0

We can write this as

(x - 5)^2 + (y + 3)^2 = r^2

where r = radius

Plugging in the point (2,5) we have

(2-5)^2 + (5+3)^2 = r^2
r^2 = 9 + 64 = 73
so the required equation is

(x - 5)^2 + (y + 3)^2 = 73

Answer:

Total interest =$1296

Step-by-step explanation:

Kevin invested $8,000 for one year at a simple annual interest rate of 6 percent

Simple interest = $\frac{Pnr}{100}$

P=8000, n=1 year and r=6

interest = $\frac{8000(1)(6)}{100}$

Interest = 480 dollars

$compound \ interest =P(1+\frac{r}{n} )^{nt}-p$

P= 10000, t=1, r=8%=0.08, n=2 for semiannually

$compound \ interest =10000(1+\frac{0.08}{2} )^{2(1)}-10000$

Interest = 10816- 10000=816

Total interest = $480+816=1296$

How can I do this question

TiliK225 [7]

Hello!

First you have to find the area of the floor

To do this you multiply the sides

4 * 4 = 16

Next you find the area of the rug which is a circle

The equation for this is A = $\pi r^{2}$

r is radius

Put in the values you know

$A = \pi 1.5^{2}$

A = 7.07

Subtract this by the area of the floor

16 - 7.07 = 8.93

The answer is 8.93m squared

Hope this helps!

I need help this is half of my grade!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Another easy way to remember the area of a square is s*s, or side times side.

if one side is 6 centimeters, then the other 3 are also 6 because it's a square.

so you can either do 6*6 = 36

or 6^2 = 36
