Pretty sure the answer is 27000000 therefore there are six zeros in the number. <span />
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
1. A squares and square root cancels
2. CE square root of a perfect square is rational square root of non perfect squares are irrational
4. ✓16=4 ✓9 =3 therefore ✓10 will be between 4 and 3 which is 3.1 answer is C
y-2=5(x-(-3))
or
y-2=5(x+3)
(they represent the same thing)
