Answer:

<h2>A(55) =  - 201</h2>

Step-by-step explanation:

<h3>A(n) = 15 - 4(n - 1)</h3>

Since we are finding the 55th term, n = 5 .

Substitute this value into the above formula

That's

<h3>A(55) = 15 - 4(55 - 1) \\  = 15 - 4(54) \\  = 15 - 216</h3>

We have the final answer as

<h3>A(55) =  - 201</h3>

Hope this helps you

Cos(x)= 40/41 and x lies in Q4. Find sin(x)
notka56 [123]

Step-by-step explanation:

\sin(x)  =  \sqrt{1 -  {cos}^{2}x }

\sin(x ) =   \sqrt{1 -  { (\frac{40}{41} )}^{2} }

\sin(x)  =  \sqrt{ \frac{1681 - 1600}{1681} }  =  \sqrt{ \frac{81}{1681} }

sin(x)=±9/41

As x lies in Quadrant 4 , sin(x) = -9/41

A 500500-gallon tank initially contains 200200 gallons of brine containing 100100 pounds of dissolved salt. brine containing 11
mixer [17]
Let A(t) denote the amount of salt in the tank at time t. We're given that the tank initially holds A(0)=100 lbs of salt.

The rate at which salt flows in and out of the tank is given by the relation

\dfrac{\mathrm dA}{\mathrm dt}=\underbrace{\dfrac{11\text{ lb}}{1\text{ gal}}\times\dfrac{44\text{ gal}}{1\text{ min}}}_{\text{rate in}}-\underbrace{\dfrac{A(t)}{200+(44-11)t}\times\dfrac{11\text{ gal}}{1\text{ min}}}_{\text{rate out}}
\implies A'(t)+\dfrac{11}{200+33t}A(t)=484

Find the integrating factor:

\mu(t)=\exp\left(\displaystyle\int\frac{11}{200+33t}\,\mathrm dt\right)=(200+33t)^{1/3}

Distribute \mu(t) along both sides of the ODE:

(200+33t)^{1/3}A'(t)+11(200+33t)^{-2/3}A(t)=484(200+33t)^{-1/3}
\bigg((200+33t)^{1/3}A(t)\bigg)'=484(200+33t)^{-1/3}
A(t)=484\displaystyle\int(200+33t)^{-1/3}\,\mathrm dt
A(t)=22(200+33t)^{2/3}+C

Since A(0)=100, we get

100=22(200)^{2/3}+C\implies C\approx-652.39

so that the particular solution for A(t) is

A(t)=22(200+33t)^{2/3}-652.39

The tank becomes full when the volume of solution in the tank at time t is the same as the total volume of the tank:

200+(44-11)t=500\implies 33t=300\implies t\approx9.09

at which point the amount of salt in the solution would be

A(9.09)\approx733.47\text{ lb}
