I just took the test and i know it is not A
Step-by-step explanation:
Answer:
0.7176 m/s m/s
Step-by-step explanation:
We are given;
Rate = 3 rev/min
Diameter: d = 15 ft
Now, we want to find how fast the stream is flowing which is the linear velocity.
Thus;
linear velocity = circumferential distance × number of revolutions
Now, circumferential distance = πd
Circumferential distance = 15π
Thus;
linear velocity = 15 × π × 3 = 45π ft/min
Converting to m/s gives;
Linear velocity = 45π/197 m/s
Linear velocity = 0.7176 m/s
It would be...
(18 +28) divided by two
then take that and multiply it by the height - 5
the 6 in this equation doesn't matter because it is not the height of the shape
Answer:
-8*2x would be -16x and -8*-8=64 so the ansewer would be _16x+64
