Write a circle equation for it <br>help please​
melomori [17]

Answer:

(x + 2)² + (y - 4)² = 16

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k ) = (- 2, 4 ) and r = 4 , then

(x - (- 2))² + (y - 4)² = 4² , that is

(x + 2)² + (y - 4)² = 16

sergij07 [2.7K]

an equation for a circle has formula

(x-m)² + (y-n)² = r²

where (m,n) is its center

and r is its radius

so, the equation has center (4,3) and radius 4

the equation is derived from the pythagorean theorem

A clothing store advertises that it is having a 25% off sale. for one day only, the store advertises and additional savings of 1
kogti [31]

Let assume x be the sale price

A clothing store advertises that it is having a 25% off sale.

The sale price with 25% discount is f(x) = sale price - 25% of sale price

f(x)= x - 0.25x = 0.75x

For one day only, the store advertises and additional savings of 10%.

The sale price with 10% discount is g(x) = sale price - 10% of sale price

g(x)= x - 0.10x = 0.90x

Use composition function

g(f(x)) = g( 0.75x) = 0.90(0.75x) = 0.675x

That is 0.675/100 = 67.5%

The total percent discount = 100% - 67.5% = 32.5%

what would be the sale price of a $40 sweater?

Here sale price x= 40

So we plug in 40 for x

g(f(40)) = g( 0.75(40)) = 0.90(0.75(40)) = 0.675(40) = 27

The sale price of sweater = $27

This means that if the length a = 2 then the length b = 3.236. in this case what is the length c
givi [52]
Basically what tou have to do in order to find this answer, is to find the rule. The rule in this partiular problem is 1.236 because 3.236-2=1.236. So since the rule is 1.236, all you have to do is 1.236 to 3.236 which is 2.472.
