Answer:
Step-by-step explanation:
hello :
f(x) = a(x - h)²-k ....vertex form when the vertex is : (h,k)
h=1 and k=0 so : f(x) = a(x-1)²
a parabola that passes through the point (2,8) : f(2)=8
a(2-1)² =8
a= 8
f(x) = 8(x-1)²= 8(x²-2x+1)
f(x) 8x²-16x+8 .....standard form
1/12
Work out the area of this circle. Take pie to be 3.142 and give your answer to 2 decimal places.
0.25k + 1.5 - k - 3.5 = -0.75k - 2.
y=5x-2
x= 85°
