The rate of change in revenue for Under Armour from 2004 through 2009 can be modeled by dR /dt = 13.897t + 284.653 t where R is

MakcuM [25]

Answer:

The revenue is $R(9) = \$ 876.9$

Step-by-step explanation:

From the question we are told that

The rate of change in revenue for Under Armour from 2004 through 2009 is

$\frac{d R }{dt } = 13.897t + \frac{284.653}{t}$

Now

$dR = (13.897t + \frac{284.653}{t})dt$

Integrating both sides to obtain R(t)

$\int\limits dR = \int\limits (13.897t + \frac{284.653}{t})dt$

$\int\limits dR = \int\limits (13.897\frac{t^2}{2} + 284.653(ln (t)) ) + C$

=> $R(t) = 6.9485t^2 + 284.653(ln (t) ) + C$

From the question we have that at t = 8 $R(8)= \$ 725.2 \ million$

$725.2 = 6.9485(8)^2 + 284.653(ln (8) ) + C$

=> $C = -311.4$

$R(t) = 6.9485t^2 + 284.653(ln (t) ) -311.4$

At t = 9

$R(9) = 6.9485*(9)^2 + 284.653(ln (9) ) -311.4$

$R(9) = \$ 876.9$

Anna [14]

Answer:

$99

Step-by-step explanation:

Cost of electricity per year= $165

Tax per month= 5%

Amount of tax paid per month= 5% of $165

= 0.05 × 165

= $8.25

Ella's family pays $8.25 tax per month

There are 12 months in 1 year

Ella's family will pay Ina year = $8.25 × 12

= $99

Ella's family will pay $99 tax for an entire year
