Answer:

(1.21875, 23.765625)

Step-by-step explanation:

-b/2a gives you the x value of the maximum point, with b=39 and a = -16

-39/2(-16) = 1.21875 = x

Plug that value back in and get the y value

[tex]-16(1.21875)^{2} + 39(1.21875) = 23.765625[/tex] would be the y value.

I included all the digits because you didn't tell me how many significant figures.
