Answer:
undefined
Step-by-step explanation:
slope = ((y2-y1)/2) / ((x2 - x1 )/2)
since x1 = x2
so x2 - x1 = 0
then ((y2-y1)/2) / 0 = undefined
Answer:
5/7 is the only one
Step-by-step explanation:
Answer:
63 yd²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A =
h (a + b)
where a and b are the parallel bases and h the perpendicular height.
Here a = 8, b = 10 and h = 7, thus
A = 0.5 × 7 × (8 + 10) = 0.5 × 7 × 18 = 63 yd²
50 over 360 * 7.2*pi = 3.14159...
