Answer:

y = x² - 8x + 18

Step-by-step explanation:

vertex form based on vertex of (4,2) and point (2,6)

y = a(x - 4)² + 2

find 'a':

6 = a(2 - 4)² + 2

6 = 4a + 2

4 = 4a

a = 1

Convert y = (x - 4)² + 2 to standard form:

y = x² - 4x - 4x + 16 + 2

y = x² - 8x + 18

What is the circumference, in inches, of a circle with an area of 81π square inches?

Troyanec [42]

If area is 81pi then 81pi=pir^2. Divide both sides by pi and we are left with r^2=81 take the square root of both sides to find the radius is 9 then plug that into the equation for circumference(2pir) so 2pi(9)=18 pi so the answer is E 18pi
