Answer:
Option C.
Step-by-step explanation:
The equation that models the position of the weight and time will be a sine wave.
y = A sin(bt)
where A = amplitude of the wave
b = time period for a complete oscillation
Since b =
It has been given in the question, Time period t = 3 sec.
b =
Amplitude A = 2 in.
Now we plug in the values of amplitude and time period in the standard equation.
y =
y =
Option C. is the answer.
Answer:
The correct answer is:
Step-by-step explanation:
As stated in the question that x represents the number of minutes his <em>normal</em> commute takes. Here the keyword is normal; in the <em>normal</em> commute, Ken takes side streets instead of the toll road.
However, in this scenario, we have to come up with the equation that takes Ken's commute via <em>toll road</em>.
Ken can travel 3 times faster by taking the toll road (Given), which can be represented in the mathematical terms in terms of x as follows:
<em>Without considering Ken getting late, </em>the equation would become the following:
--- (A)
<em>As Ken is leaving late</em>, we have to incorporate that time as well by <em>adding</em> it in the aforementioned equation (A).
In this case, it's 20 minutes; therefore, the equation (A) will become:
Hence, the correct answer is .
