Answer:

The vertex is (-3,-2)

Step-by-step explanation:

We can write the equation for a parabola in the form

y = a(x-h)^2 +k where (h,k) is the vertex

y =-2 (x - 3)^2 - 2

h = -3 and k =-2

The vertex is (-3,-2)

Tom decides to paint one wall in his room green. Use the dimensions below to calculate the area of the this wall.

Anton [14]

Option C:

Area of the wall $=94\frac{15}{16}$ square feet

Solution:

Length of the wall = $12 \frac{1}{4}$ feet

Width of the wall = $7 \frac{3}{4}$ feet

Area of the wall = length × width

$$=12 \frac{1}{4}\times 7 \frac{3}{4}$

Convert mixed fraction into improper fraction.

$$=\frac{12 \times 4+1}{4}\times \frac{7\times 4+3}{4}$

$$=\frac{49}{4}\times \frac{31}{4}$

$$=\frac{1519}{16}$

Convert improper fraction into mixed fraction.

$$=94\frac{15}{16}$

Area of the wall $=94\frac{15}{16}$ square feet

Option C is the correct answer.
