(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

Lunna [17]

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, $\frac{dB}{dt}=4$

Which statement is true? Question 5 options: All rectangles are squares. All quadrilaterals are rectangles. All squares are rect

lozanna [386]

Answer:

All squares are rectangles.

Step-by-step explanation:

The requirements for a shape to be qualified as a rectangle are that there must be four sides, two sets or parallel sides, and four right (90 degree) angles. The requirements for a square are that all sides must be equal in length and that there must be four right angles. Since the requirements of a square fit under those of a rectangle, all squares are rectangles.
