Answer:
Step-by-step explanation:
hello :
f(x) =-2x²+4x+1 Completing The Square : f(x) =2(x²+2x)+1
f(x) = -2((x²-2x+1)-1)+1
f(x) = -2((x-1)²-1)+1
f(x) =2(x-1)²+1 ... verex form when the vertex is (1,1)
the axis of symmetry is x=1
Answer:
region D
Step-by-step explanation:
all other regions are higher than $300
Since we know a circle has 360 degrees, the sector bounded by a 90 degree arc will be a quarter of circle (360/90 = 4). Then, to calculate the area of that sector, we can calculate the total area of the circle of radius 10, and then divide it by 4.
The area of a cirlce of radius r is:

Then, the area of the sector would be:
