Answer:

Step-by-step explanation:
We have to find the derivative of the following function:
Now, differentiating both sides with respect to x we get,
⇒
(Answer)
{Since, we know that,
and
}
Answer:
Brand b has a better unit price.
Distance equals rate times time, so:
D = (66 ft/s) * t
This can happen if you add another independent variable to your regression model that is strongly correlated to some other variable already in the model.
This is called multicollinearity.
If there is a high correlation between your independent variables can lead to problems.
<span>It can lead to increased variance of the coefficient estimates and make the estimates very sensitive to minor changes in the model.</span>
If you have covered function tranformations
is an exponential function, likely something like

but shifted upwards by 3 units and with a coefficient multiplying "x" something like "2"
so... try graphing in your calculator
