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

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

$R(9) = \$ 876.9$

adam and betty purchased a printer together for $258. If adam paid $18 less than twice betty, how much money did Adam pay for th

LenKa [72]

Answer:

Step-by-step explanation:

Let A = Adam, B = Betty

Adam and Betty purchased a printer together for $258.

This means we can say A + B = 258.

We are also told Adam paid $18 less than twice Betty.

You can write this as:

Adam = 2 x Betty - 18

A = 2B - 18

Substitute "A" into the A + B equation and you get:

A + B = 258

2B - 18 + B = 258

3B - 18 = 258

Add 18 to both sides.

3B = 258 + 18

3B = 276

Divide both sides by 3 to find B

B = 276/3 = 92 (This means Betty paid $92).

Since the total that they paid together was $258.

This means Adam pays the Total - How much Betty paid

Adam = 258 - 92 = $166
