Answer:

original height = .2(8) + 13.4 = 15 inches

Step-by-step explanation:

To find the original height you multiply .2 by 8 to see how much was burned and then you add that to whats left (13.4) to give you the original height.

Mkey [24]

Answer:

D: $\frac{3}{(6-6)}$

Step-by-step explanation:

Option A equates to $-\frac{0}{2}=0$

Option B equates to $\frac{(-4+0)}{8}=\frac{-4}{8}=-\frac{1}{2}$

Option C equates to $0\div11 =0$

Option D equates to $\frac{3}{(6-6)}=\frac{3}{0}$ which cannot be defined as division by 0 is impossible

Step-by-step explanation:

The first parabola has vertex (-1, 0) and y-intercept (0, 1).

We plug these values into the given vertex form equation of a parabola:

y - k = a(x - h)^2 becomes

y - 0 = a(x + 1)^2

Next, we subst. the coordinates of the y-intercept (0, 1) into the above, obtaining:

1 = a(0 + 1)^2, and from this we know that a = 1. Thus, the equation of the first parabola is

y = (x + 1)^2

Second parabola: We follow essentially the same approach. Identify the vertex and the two horizontal intercepts. They are:

vertex: (1, 4)

x-intercepts: (-1, 0) and (3, 0)

Subbing these values into y - k = a(x - h)^2, we obtain:

0 - 4 = a(3 - 1)^2, or

-4 = a(2)². This yields a = -1.

Then the desired equation of the parabola is

y - 4 = -(x - 1)^2
