(e) The number of bees spotted in Amelie's garden can also be modeled by the function B(x) = 50√ k + 2x where x is the daily hig

h temperature, in degrees Fahrenheit, and k is a positive constant. When the number of bees spotted is 100, the daily high temperature is increasing at a rate of 2 ◦F per day. According to this model, how quickly is the number of bees changing with respect to time when 100 bees are spotted?

Answer:

\frac{dB}{dt}=4

Step-by-step explanation:

Derivative indicates rate of change of dependent variable with respect to independent variables. It indicates the slope of a line that is tangent to the curve at the specific point.

Given:

Number of bees is modeled by the function B(x)=50\sqrt{k}+2x

The daily high temperature is increasing at a rate of 2 °F per day when  the number of bees spotted is 100.

To find:

rate of change of number of bees when 100 bees are spotted

Solution:

B(x)=50\sqrt{k}+2x

Differentiate with respect to t,

\frac{dB}{dt}=0+2(\frac{dx}{dt}) \\\frac{dB}{dt}=2(\frac{dx}{dt}) \\

Put (\frac{dx}{dt}) =2

\frac{dB}{dt}=2(2)=4

At x = 100, \frac{dB}{dt}=4

The answer is [ all real numbers ]

The domain are the input values which makes the function defined and real.

Since we don't have any constraints or any undefined points, the domain could be literally anything. Thus proves out answer.

Best of Luck!
