The length pf a rectangle is given by 2t +3 and its height is square root t, where t is time in seconds and the dimensions are in centimeters. find the rate of the change of the area with respect to time. a'(t)=

Step-by-step explanation:

Given : Length of rectangle = 2t+3

           Height of rectangle =

To Find: Find the rate of the change of the area with respect to time.

Solution:

Area of rectangle =

                              =

                              =

                              =

So,

Hence the rate of the change of the area with respect to time is                                                                                      

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

step-by-step explanation:

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
