Answer:

117.6 ft

Step-by-step explanation:

You have two legs of the triangle and an angle, so you'll use tangent here. Sin and cos both involve hypotenuse, which you're not given.

Remember SOHCAHTOA

Tangent = Opposite / Adjacent

The side opposite the angle is the height, the side adjacent to the angle is the 25 ft.

tan(78°) = height / 25

25tan(78°) = height = 117.6 ft.

F(x) = 2x2 + 12x + 1<br> Determine the vertex

Gnom [1K]

Answer:

Step-by-step explanation:

The vertex would be the highest/lowest point so lets factor this first

when we factor we get

2(x^2+6x+8)

2(x+4) (x+2)

Using zero product property we find the 2 x values and x intercepts are

-4 and -2

the middle point of these points is -3

Substitute -3 for x and solve

2(-3+4) (-3+2)

2 * 1 * -1

2*-1

-2

(-3,-2) is the vertex
