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
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
Hello!
To find this answer you will need find what 1/3 of 153 is so
153/3 = 51 which is the answer
Hope this helps!
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
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.
