Answer:
Step-by-step explanation:
According to the Remainder Theorem; when P(y) is divided by y-a, the remainder is p(a).
The first polynomial is :
When p(y) is divided by y-5, the remainder is
When the second polynomial:
is divided by y-5.
The remainder is;
The two remainders are equal;
Answer:
v ≈ 8.5 km/h
Step-by-step explanation:
Since the diameter of the wheel is 3 m the radius will be r = 1.5 m.
Use the radius of the water wheel to find it's circumference C:
[set r = 1.5 m]
⇒
⇒ m
One revolution of the water wheel corresponds to meters so the angular velocity 15 rmp (revolutions per minute) corresponds to:
=
/min
Using this result, the speed of the river in kilometers per hour will be:
×
×
⇒
⇒ ≈
km/h
