Answer: Yes, because you only need 249 in^2 and it will cover 280 in^2
Step-by-step explanation:
SA=LW+2WH+2LH
SA=13(9)+2(9)(3)+2(13)(3)
SA=249 IN
Answer:
Step-by-step explanation:
There are several possible outcomes. If your cross section is created by intersecting the cone with a plane parallel to the base of the cone, the cross section is a circle. If the plane is held vertical, the cross section could be a hyperbola. If the intersecting plane is neither vertical nor horizontal, the cross section could be an ellipse.
Y = x^2 - 2x
y = -2x - 1
x^2 - 2x = -2x - 1
x^2 - 2x + 2x + 1 = 0
x^2 + 1 = 0
x^2 = -1
x = square root (-1).........NO SOLUTIONS
