The top one and bottom one
Both a rhombus and a rectangle have diagonals that are perpendicular bisectors, but the ones formed in a square are all congruent, so that is probably the most descriptive one.
X-intercept
-4x=-2(0)-1
-4x=-1
x=1/4
Y-intercept
-4(0)=-2y-1
0=-2y-1
2y=-1
y=-1/2
Answer:
172.7sqft (square feet)
Step-by-step explanation:
SA = 2(pi)(r)(h) + 2(pi)r^2
plug in the radius, height, and find SA, then multiply by 10 fenceposts.
SA= 2(3.14)(.5)(6)
Solve
SA=14.39166
Multiply by 12
Answer is 172.7sqft
