Answer:
Time taken to complete 100 revolutions will be 964 s
Step-by-step explanation:
Diameter of paddle wheel = 4 ft
So, circumference of wheel = C = π d
=> C = 4π
We know, the formula of speed s = d/t
where d is distance traveled and t is time taken.
We are given speed s= 1.3
Distance of wheel is equal to its circumference so, time taken will be:
s= d/t
=> t = d/s
=> t = 4π / 1.3
=> t = 3.07 * 3.14 s
=> t = 9.64 s
So, time taken to complete 100 revolutions will be:
9.64 * 100 = 964 s
Time taken to complete 100 revolutions will be 964 s
0.1639
.6 / 3.66 , just divide it
A=48
b=144
c=-84
First, you simplify the second equation by multiplying 6 to 2x and 6 to 7. Then, you get the two equations, (4x-2) times (12x+42). You then use the FOIL method, multiplying 4x to 12x, 4x to 42, -2 to 12x, then -2 to 42. Simplify. Then number before x squared is your a value, value before x is b, and the value without x is c.
