Answer: Choice D. y = (x-1)^2 - 3
The vertex is (h,k) = (1,-3). So h = 1 and k = -3.
We have a = 1 as the leading coefficient.
Plug those values into the equation below
y = a(x-h)^2 + k
y = 1(x - 1)^2 + (-3)
y = (x - 1)^2 - 3
A square has the same length on all of it's sides. The area of a square is side times side. So it's 2.2×2.2=?
Answer:
C
Step-by-step explanation:
Triangle area formula: base*height/2
so, 14*10/2 = 7*10 = 70 sq. in.
