The equation x^2 + y^2 + 21 = 40 + 18y. What is the radius of this cookie?

trapecia [35]

Answer:

The radius is 10

Step-by-step explanation:

Given

$x^2 + y^2 + 21 = 40 + 18y.$

Required

The radius

Rewrite as:

$x^2 + y^2 - 18y = 40-21$

Subtract 81 from both sides

$x^2 + y^2 - 18y +81= 40-21+81$

Expand

$x^2 + y^2 - 9y - 9y +81= 40-21+81$

Factorize

$x^2 + y( y- 9) - 9(y -9)= 40-21+81$

Factor out y - 9

$x^2 + (y- 9) (y -9)= 40-21+81$

Express as squares

$x^2 + (y- 9)^2= 100$

$x^2 + (y- 9)= 10^2$

The equation of a circle is:

$(x - a)^2 + (y- b)= r^2$

By comparison:

$r^2=10^2$

$r = 10$

What is the percent of decrease from 500000 to 60000

DIA [1.3K]

Percent change = (new number - old number)/(old number) * 100

If the percent change is positive, it is a percent increase.
If the percent change is negative, it is a percent decrease.

In our case, the number goes from 500000 (the old number) to 60000 (the new number).

percent change = (new number - old number)/(old number) * 100

percent change = (60000 - 500000)/(500000) * 100

percent change = -88%

Answer: the percent decrease is 88%
