i haven't submitted a single assignment for this class since winter break bc i didn't realize she was assigning things on goform
rosijanka [135]

Answer and Step-by-step explanation:

<u>Trigonometric Function (These only work for right triangles):</u>

SOH-CAH-TOA

S = Sine = sin

C = Cosine = cos

T = Tangent = tan

O = Opposite (side)

H = Hypotenuse (side)

A = Adjacent (side)

SOH = sin(angle) = \frac{opposite}{hypotenuse}

CAH = cos(angle) = \frac{adjacent}{hypotenuse}

TOA = tan(angle) = \frac{opposite}{adjacent}

1. sinQ (Q is the angle) = \frac{14}{50}  = \frac{7}{25} = 0.28

Use Pythagorean Theorem to find side PQ.  14^{2} + PQ^{2}= 50^{2} \\PQ^{2}  = 2304\\PQ = 48

2. cosQ = \frac{48}{50} = \frac{24}{25} = 0.96

3. tanQ = \frac{14}{48}  = \frac{7}{24}  = 0.29

For the given equation, find the values of a, b, and c, determine the direction in which the parabola opens, and determine the y
mariarad [96]

Answer:

Table A

Step-by-step explanation:

y  = 3x^2 +2x -8

The quadratic is in the form

y = a x^2 +bx+c

a = 3  b = 2 c = -8

Since a > 0 it opens up

The y intercept is c so the y intercept is -8
