Find the vertex of y=-x^2+6x-12

1 answer:

8 0

You find the x coordinates using x = -b/2a = -6/2(-1) = 3

Substitute 3 in the equation and find y

y = -(3^2) + 6(3) - 12 = -9 + 18 - 12 = -3

Vertex (3,-3)

Find tan if sin= 21/35. <br><br>37 points

LekaFEV [45]

Answer:

tan=0.75

Step-by-step explanation:

We know sin=opp/hyp, so 21 is the opposite side length in relation to theta.

To figure out tan, we need to know what the adjacent angle is because tan=opp/adj

21 squared= 441

35 squared =1225

1225-441= 784

The square root of 784 = 28

Now that we know both the opp and adj sides, we can solve for tan.

21/28= 0.75

In AFGH, m_F= 65°, m_G = 55°, and m_H = 60° Which side of AFGH is

zhenek [66]

Answer:

D. FH

Step-by-step explanation:

Angle G is the smallest, so the side of the triangle opposite that angle will be the shortest. That is the side that does not contain G in its segment name:

FH is the shortest side . . . . choice D

_____

The attachment shows a triangle with these angle measures drawn to scale. You will note that FH is the shortest side.

Please be aware that different instances of this question may have different angle measures, or may have answer choices in a different order. The thing to remember is that <em>the lengths of sides have the same ordering (least to greatest) that the angle measures do</em>.
