Answer:
<h3>
y = 2(x - 3)² - 20</h3>
Step-by-step explanation:
y = a(x - h)² + k - vertex form of the equation of the parabola with vertex (h, k)
So the equation of the parabola with vertex (3, -20):
y = a(x - 3)² + (-20)
y = a(x - 3)² - 20
The parabola passes through point (7, 12) so if x=7 then y=12
12 = a(7 - 3)² + (-20)
12 +20 = a(4)² - 20 +20
32 = 16a
a = 2
Therefore the equation of the parabola with vertex (3, -20) and that passes through point (7, 12):
y = 2(x - 3)² - 20
Answer:
3
Step-by-step explanation:
Because you can see there was one cube length in figure A and there was 3 cubes length in figure B.
Answer: d^(2) + (ab)/(c)
Step-by-step explanation:
U=-2. Subtract the 10 on both sides of the equal sign to get 4u=-8. After divide both sides by 4 to get “u=-4”
