A new DVD is available for sale in a store one week after its release. The cumulative revenue,
ratelena [41]

Answer:

f(2) = $180.22

f'(2) = $130.00/week

f'(2)/f(2) = 72.13%

Two weeks after the DVD was released,  the revenue from sales is $180.22 and is increasing at a rate of $130 per week,  or 72.13% per week.

Step-by-step explanation:

The revenue from sales, in dollars, as a function of time, in weeks, is given by:

f(t)=260ln(t)

After two weeks (t=2), the revenue from sales is:

f(2)=260ln(2)\\f(2) = \$180.22

The rate of change, which is given by the derivate of the revenue function, at t = 2 weeks is:

f'(t)=\frac{d}{dt} 260ln(t)\\f'(t) = \frac{260}{t}\\f'(2) = \frac{260}{2}=\$130.00/week

The relative rate of change is:

\frac{f'(2)}{f(2)}=\frac{130}{180.22}=0.7213=72.13\%

Therefore, Two weeks after the DVD was released,  the revenue from sales is $180.22 and is increasing at a rate of $130 per week,  or 72.13% per week.

6. The height of a triangle is 2 units more than the base. The area of the triangle is 10 square units. Find
Harrizon [31]

Answer:

4.24

Step-by-step explanation:

First, let's set up the equation: \frac{2+x^2}{2}=10

Next, clear the fraction by multiplying both sides by 2:2*(\frac{2+x^2}{2}=10)=2+x^2=20

Then, subtract 2 from both sides: x^2=18

Finally, take a square root of both sides and round: \sqrt{x^2=18} =(Rounded to the nearest hundredth) 4.24
