Its letter D
7(19)-21 (x=19)
133-21=112 (RZ)
112+112=224 (RT)
5π rad/sec= 60 x 2.5 = 150 rpm. The bicycle travels 27π inches per revolution
<span>150 rpm = 150 x 27π in/min = (150 x 27π x 60)/(5280 x 12) = 12.05 mph </span>

Answer:
8
Step-by-step explanation:
0 = –x^2 + 4x – 2
This is of the form

a = -1 b = 4 x = -2
The discriminant is
b^2 -4ac
4^2 - 4(-1)(-2)
16 - 8
8
