Find a function whose graph is a parabola with vertex (7, 8) and that passes through the point. (6, −9).
lukranit [14]
Work backwards from vertex form. Vertex form of a quadratic equation/parabola is the following: 

f(x) = a(x - h)² + k, where (h, k) is the vertex. 

f(x) = a(x - 6)² - 9 

Now, plug in the point that you're given to SOLVE FOR A. Remember that f(x) is just another way of writing y. 

8 = a(1)² - 9 
8 = a - 9 
a = 17 

So, plug in a = 17 into the equation. 

<span>f(x) = 17(x - 6)² - 9 ←← your answer.


I hope my answer has come to your help. Thank you for posting your question here in Brainly.

Answer:

find total volume to find what amount is 20%

hack, is put the 20% in alreadyy to find 20% volume

20%=1/5

so

vcone=1/3(hpir^2)

times thath by 1/5

vcone=1/15(hpir^2)

d/2=r

given

4.8=d

4.8/2=d/2=r=2.4

10=h

V=1/15(10pi2.4^2)

V=1/15(10pi5.76)

V=1/15(57.6pi)

V=3.84pi

V=12.0637 cubic inches=20% of vase

0.5 cubc inches per min

0.5 times t=12.0637

divide both sides by 0.5

t=24.1237

about 24 minutes
