I am not going to do the work for you, since this easy with this information:
Quadratic- involving the second and no higher power of an unknown quantity or variable
Linear- Arranged in straight or almost straight line
Exponential- Increasing
Answer:
y = 3x² + 54x + 240
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
here (h, k) = (- 9, - 3), thus
y = a(x + 9)² - 3
To find a substitute either of the roots into the equation
Using (- 8, 0), then
0 = a(- 8 + 9)² - 3
0 = a - 3 ( add 3 to both sides )
a = 3
y = 3(x + 9)² - 3 ← in vertex form
Expand factor and simplify
y = 3(x² + 18x + 81) - 3
= 3x² + 54x + 243 - 3
= 3x² + 54x + 240 ← in standard form
hi <3
i think this makes more sense if you draw a diagram
so basically, as we are working out the horizontal component, decide if you need to use sin or cos.
as the side is next to the angle, you would use cosine.
thus, your answer would be 27cos49
(the vertical component would be 27sin49)
hope this helps :)
