Y = 3x² - 15x + 30
y = 3(x² - 5x) + 30
y = 3(x² - 5x + (5/2)²) + 30
y = 3(x - 5/2)² + 30
The parabola opens upwards. Vertex at (5/2, 30)

ANSWER:
Let hypotenuse be h.
On using trigonometric function, we get.
sin52° = 12/h
0.788 = 12/h
h = 12/0.788
h = 15.2 rounded.
=-3x +15 -3x + 2
= 15 +2
= 17
Answer: w= -4
Step-by-step explanation:
7w-180=52w
Subtract 7w on both sides.
-180=45w
Divide both sides by 45.
-4=w
