Answer:

- the angle at H is 120 degrees

- the missing segment is DC

Step-by-step explanation:

The "roof" FGH is bigger than 90 degrees because FG and GH are not acute. .

Without instruction we can assume FGH is 120 degree.

This means GHF is 30 degrees to complete the triangle FGH.

So the angle around H, or JHG is 90 + 30 = 120 degrees

For the ratio, we can simply look at the comparison between the small figure   DJHGF

and the large figure DCBAE, and we see that the denominator

DJ in the small figure is DC in the large figure.

F(x)=-2x^2+3x+7 find f(3)
Inessa [10]

Answer:

f(3) = -2

Step-by-step explanation:

Given the f(x) = -2x² + 3x + 7, to find f(3):

We can substitute 3 as the value of x in the given function:

f(x) = -2x² + 3x + 7

f(3) = -2(3)² + 3(3) + 7

f(3) = -2(9) + 9 + 7

f(3) = -18 + 9 + 7

f(3) = -9 + 7

f(3) = -2

Therefore, f(3) = - 2.
