Answer:
47 +3 sin(
)
Step-by-step explanation:
Here temperature of reaction oscillates about 47.
Temperature amplitude is 3.
Most popular and simple function which can describe the temperature is sinosuidal function.
We know sinosuidal function can be negative as well as positive with magnitude as it's amplitude.
We need angular frequency for this.
Time period is given =4 min
Angular frequency =
=![\frac{2\pi }{4}](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Cpi%20%7D%7B4%7D)
So temperature as a function of time is
T(t) = 47 + sin(
)
Answer:
6=-3/4x+(-4)
Step-by-step explanation:
The equation of any straight line, called a linear equation, can be written as: y= mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis. So for the given information you can see that they gave you your slope of -3/4 so you fill that in under the m. The point that would cross the y axis would be -4 because when you think of it on a graph you would see it as (-4 y) and (6 x). When you are writing linear equations you use the form y=mx+b.
Hope this helps
Answer: 2(x^2-7)
Step-by-step explanation:
1.8 TIMES 3 = 5.4. Therefore, the new price is 12.6.
208/100 = 2.8 bc u move the decimal over twice because there are two zeros
