Evaluate the integral. (remember to use absolute values where appropriate. Use c for the constant of integration.) 5 cot5(θ) sin

ozzi

$I=5\int \frac{cos^{4}\theta }{sin\theta }\times cos\theta d\theta \\\\I=5\int \left ( 1-sin^{2}\theta \right )^{2}\times \frac{cos\theta }{sin\theta }d\theta \\put\ \sin\theta =t\\\\dt=cos\theta d\theta \\\\I=5\int\frac{t^{4}+1-2t^{2}}{t}dt\ \ \ \ \ \ \ \ \ \ \because (a-b)^2=a^2+b^2-2ab\\\\I=5\left ( \int t^{3}dt + \int \frac{1}{t} -2\int t \right )dt$

by using the integration formula

we get,

$\\I=5\left ( \frac{t^{4}}{4} +logt -t^{2}\right )\\\\I=\frac{5}{4}t^{4}+5\log t-5t^{2}+c$

now put the value of t=\sin\theta in the above equation

we get,

$\int 5\cot^5\theta \sin^4\theta d\theta=\frac{5}{4}sin^{4}\theta+5\log \sin\theta - 5sin^{2} \theta+c$

hence proved

G(n)=-n^3+3n^2, find g(-4)

Sauron [17]

Answer:

g(-4) = 112

Step-by-step explanation:

Hi there!

$g(n)=-n^3+3n^2$

To find g(-4), replace all n's with -4:

$g(-4)=-(-4)^3+3(-4)^2\\g(-4)=-(-64)+3(16)\\g(-4)=64+48\\g(-4)=112$

I hope this helps!

Shanice invests $5,887 in a retirement account with a fixed annual interest rate of 4% compounded 12 times per year. How long wi

qwelly [4]

Answer:

It takes 14 years for the account balance to reach $10,296.62

Step-by-step explanation:

Given:

Principal amount = $5,887

Rate of interest = 4% and 12 times per year

Balance amount = $10296.62

To find:

The time to reach $10,296.62 = ?

Solution:

We know that

$N(t) = N_0e^{rt}$

Here,

N(t) = 10,296.62

$N_0$ = $5,887

r = 4 % = 0.04

we have to find the t value

On substituting the given values

$10,296.62 = 5,887e^{0.04t}$

Taking ln to remove e we get

ln $ln(10,296.62) = ln(5887)({0.04t)$

$ln(\frac{10296.62}{5887}) = 0.04t$

ln(1.749) = 0.04t

$t = \frac{ln(1.749)}{0.04}$

$t =\frac{ 0.5590}{0.04}$

t = 13.97

t = 14

an amusement park ride cannot safely restrain people under 50 in tall or over 78 in tall. write two different inequalities that

Tcecarenko [31]

Y>50
y<78

so since u cant be less that 50 u have to be more and since u cant be taller than 78 u have to be less than 78

now:
y<78 but >50
