Answer:
D
Step-by-step explanation:
Solution:-
The standard sinusoidal waveform defined over the domain [ 0 , 2π ] is given as:
f ( x ) = sin ( w*x ± k ) ± b
Where,
w: The frequency of the cycle
k: The phase difference
b: The vertical shift of center line from origin
We are given that the function completes 2 cycles over the domain of [ 0 , 2π ]. The number of cycles of a sinusoidal wave is given by the frequency parameter ( w ).
We will plug in w = 2. No information is given regarding the phase difference ( k ) and the position of waveform from the origin. So we can set these parameters to zero. k = b = 0.
The resulting sinusoidal waveform can be expressed as:
f ( x ) = sin ( 2x ) ... Answer
If there were 49 cars in a line that stretched 528 feet, what is the average car length? assume that the cars are lined up bumper-to-bumper
Answer: We are given there are 49 cars
Also these 49 cars are in a line stretched 528 feet.
Now the average length of the car is:
Average length = 
=
Therefore, the average length of car is 10.78 feet
There are 120 blocks left.
Answer:
Option 3
Step-by-step explanation:
We want to work out the surface-area
This is a cylinder and the formula for the surface area of a cylinder is :
2πrh+2πr^2
^ means to the power of
The radius is 15
The length is 18
2(3.14)(15)(18) + 2(3.14){15}^2
Part 1:
(6.28)(15)(18)
(6.28)(270)
1695.6
Part 2:
First, we do the exponents,
15^2 = 225
(6.28)(225)
1413
Part 3:
1695.6 + 1413 = 3108.6
Answer: 3108.6
Hope this helps :)
