Answer:
y = ax^2 + bx + c => F(x) = 3x^2 +12x+7; F(x) = 3x^2 +12x+7 is already in standard form for the equation of a parabola.
Step-by-step explanation:
Actually, F(x) = 3x^2 +12x+7 is already in standard form, y = ax^2 + bx + c. Double check the instructions for this problem. Did you perhaps want "vertex form?"

For this case we have the following equation:
sine (40) = b / 20
From here, we must clear the value of b.
Clearing we have:
b = 20 * sine (40)
b = 12.85575219
Rounding to the nearest tenth we have:
b = 12.86 cm
Answer:
b = 12.86 cm
7x-2=-23 add 2 to both sides to get 7x by itself
7x=-23+2 now add the right side
7x=-21 now divide both sides by 7
x=-21/7
x=-3
