2x^2 - 2x + 7 = 2(x^2 -x +3) + 1 = 2(x-0.5)^2 + 17/6
I think it’s C but I’m not so sure it’s been a while
Answer:
18π or 56.5 (1 d.p) feet squared
Step-by-step explanation:
As the formula for the area of a semi circle is πr²/2 as the area of a circle is πr² so the area would be 18π or 56.5 (1 d.p)
The x-intercept is -45.
Substitute 0 for y to find x-intercept
