Answer:
Perpendicular lines
Step-by-step explanation:
MN: (-4, 8) and (-4, -6), This line parallel to y-axis as as x-value doesn't change
KL: (-8, 2) and (6, 2), This line is parallel to x-axis as y-value doesn't change
The given lines are perpendicular as one is parallel to x, another one is parallel to y
Answer:
C) 550 feet squared
Step-by-step explanation:
Imagine how the surface area of the given figure differs from the surface area of a prism 10 ft by 15 ft by 5 ft without the cutout in the top center. The three 5×5 ft squares that would need to be added to make the prism are of exactly the same area as the three 5×5 ft squares that are the sides and bottom of the cutout.
That is, the area is no different from the area of a 10 ft by 15 ft by 5 ft rectangular prism. That area is ...
A = 2(LW +WH +LH) = 2(10·15 +15·5 + 10·5) ft² = 550 ft²
You fill in the formula with the info they give you and solve for v:
5 = -16(3.5)^2 + 3.5v + 6.5 That simplifies to 5 = -196 + 3.5v + 6.5 Now simplify further by combining like terms and getting the v term by itself on one side. 194.5 = 3.5v Now divide both sides by 3.5 to get a velocity of 55.57 feet per second.
