Step-by-step explanation:
<u>Sinusoid</u>
The shape of a sinusoid is well-know because it describes a curve with a smooth and periodic oscillation. The sine and cosine are the two trigonometric functions in which the graph matches the description of a sinusoid. The sine can be identified because its value is zero at time zero.
The graph shown in the figure corresponds to a sine. The other characteristics of the sine function are
* It completes a cycle in
radians
* It has a maximum of 1 and a minimum of -1
* It's increasing for a quarter of the cycle, decreasing for half of the cycle, and increasing for the remaining quarter of the cycle
* The equation is

The function starts decreasing for the first quarter, which only is possible if the amplitude A is negative. We can also see the maximum and minimum values are 2 and -2 respectively. This means the amplitude is A=-2
We can also see the function completes 3 cycles in
radians or 6 cycles in
radians. Or, equivalently



Thus, the function can be expressed as

Let the ratio be 4x,3xand x
Then
According to question 4x+3x+x=64
Or,8x=64
Or,x=8.
Substitute the value of x
4x=32
3x=24
X=8
Answer:
B. 1/24
Step-by-step explanation:
Given: 3 inches = 6 feet
Convert 6 feet into inches.
6 feet = 72 inches
3/72. Simplying it, you get 1/24
