diameter is 15 meters then radius is 15/2 = 7.5 meters
so the amplitude is 7.5 m and height will oscillate with amplitude 7.5 m above and below the center.
midline of the oscillation will be 7.5 m
the wheel.take 8 minutes to complete revolution then it means the height will oscillate with a period of 8 minutes
Answer:
60 and 35
Step-by-step explanation:
Let:
First number = x
Second number = y [ y > x ]
According to question:
x + y = 95
= > y = 95 - x .... ( i )
y = x + 25 ...... ( ii )
From ( i ) and ( ii ) we get:
95 - x = x + 25
= > 2x = 70
= > x = 35
y = 95 - x [ x = 35 ]
= > y = 60
Therefore numbers are 60 and 35.

Answer:
216 feet
Step-by-step explanation:
The area is given by the formula ...
A = LW
Solving for width, we have ...
W = A/L = 2835 ft²/(45 ft) = 63 ft
__
The perimeter is given by the formula ...
P = 2(L +W)
P = 2(45 ft +63 ft) = 2(108 ft)
P = 216 ft
216 feet of fencing are needed to enclose the area.
Answer:
Step-by-step explanation:
first, subtract the two fractions
You will have
the un-simplified difference of those expressions
Lets try to simplify that
Lets find the roots of the polynomial from the bottom using the formula for quadratic equation, (-b +/- sqrt( b2-4*a*c)) /(2*a)
Which are x=-3, and x=1
Thus, you have (x+3)*(x-1)
So
