Answer:
Price of the printer is = $193.20
Step-by-step explanation:
Office supply store purchased an all in one printer wit a regular price = $240
After 15% off price of the printer = $240 - 15% of $240
=
= 240 - 36
= $204
The store is offering $20 mail in rebate so the price of printer after rebate
= $204 - $20
= $184
Now price of the printer including sales tax = 184 + 5% of 184
= 184 +
= 184 + 9.20
= $193.20
Answer:
(x - 3)² + (y + 9)² = 25
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
Given area = 25π , that is
πr² = 25π ( divide both sides by π )
r² = 25 ( take the square root of both sides )
r = = 5
With centre (h, k) = (3, - 9 ) and r = 5 , then
(x - 3)² + (y - (- 9) )² = 5² , that is
(x - 3)² + (y + 9)² = 25
