Answer:
A lot
Step-by-step explanation:
Hello,
I am going to remember:
y'+3y=0==>y=C*e^(-3t)
y'=C'*e^(-3t)-3C*e^(-3t)
y'+3y=C'*e^(-3t)-3Ce^(-3t)+3C*e^(-3t)=C'*e^(-3t) = t+e^(-2t)
==>C'=(t+e^(-2t))/e^(-3t)=t*e^(3t)+e^t
==>C=e^t+t*e^(3t) /3-e^(3t)/9
==>y= (e^t+t*e^(3t)/3-e^(3t)/9)*e^(-3t)+D
==>y=e^(-2t)+t/3-1/9+D
==>y=e^(-2t)+t/3+k
Answer:
1x² + 1x -3
Step-by-step explanation:
A quadratic regression is the process of finding the equation of the parabola that best fits a set of data. As a result, we get an equation of the form:
To compute manually the values of a, b and c is a rather complicated process using a technique known as least squares method.
However, we can use a scientific calculator to compute the three values and arrive at the quadratic equation
Using the points provided, the values are:
a = 1, b = 1, c = -3
The function is 1x² + 1x -3
Note that this is a best-fit function it does not necessarily pass through all 3 points but approximates. The attached graph shows that the function does indeed pass through 2 of the 3 points
The answer is A. Cause it’s the only one the says mi per hour
