12 square inches. It's basically asking for the area of the rectangle.

Yea I agree it is 12 because when u multiply 6*2 you get 12,the area of the rectangle which is the amount of space in it

The measurement of the complement of an angle exceeds the measure of the angle by 25%. Find the measurement of the angle and its

tester [92]

Let the angles be A and C

Complimentary angles, therefor 
A + C = 90 

The measurement of the complement of an angle exceeds the measure of the angle by 25% (you used a % sign so I'll use % instead of degrees) 
C = 1.25A 

Substitute 
A + 1.25A = 90 
2.25A = 90 
A = 40º <----- 
C = 50º <----- 
------------------------------ 

If you meant 25º 
A + (A + 25) = 90 
2A + 25 = 90 
2A = 65 
A = 32.5º 
C = 57.5º

In this exercise, we estimate the rate at which the total personal income is rising in the Richmond-Petersburg, Virginia, metrop

babymother [125]

Answer:

The rate at which the total income is increasing is$1627415600

Step-by-step explanation:

From the given data

Population in the area=P=961400

The rate of increase in population=dP/dt=9200

The Average Income=I=$30593

The rate of increase in Average Income=dI/dt=$1400

Now the total income is given as

Total Income=TI=PI

So the rate of increase of total personal income is given as $\frac{d}{dt}(PI)$

From the product rule of derivatives

$\frac{d}{dt}(P*I)=I*\frac{dP}{dt}+P*\frac{dI}{dt}$

Here

I is the Average Income which is given as $30593

dI/dt is the rate of increase of income which is given as $1400.

P is the population of the area which is given as 961400

dP/dt=9200 is the rate of increase of population which is given as 9200

By substituting the values,

$\frac{d}{dt}(P*I)=I*\frac{dP}{dt}+P*\frac{dI}{dt}\\\frac{d}{dt}(P*I)=30593*9200+961400*1400\\\frac{d}{dt}(P*I)=\$1627415600$

So the rate at which the total income is increasing is$1627415600
