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

D) Last week Lori earned a gross pay of $435 for working 52 hours. She is paid time-and-a-half

rusak2 [61]

Answer:

She makes 7.50 per hour

Step-by-step explanation:

Let x = regular rate

Time and a half = 1.5x

40 hours at x

52-40 = 12

12 hours at 1.5x

40x + 12 * 1.5x = 435

40x + 18x =435

58x = 435

Divide each side by 58

58x/58 = 435/58

x =7.5

She makes 7.50 per hour

miss Akunina [59]

Step-by-step explanation:

$150\geq15x\to15x\leq150\qquad\text{divide both sides by 15}\\\\\dfrac{15x}{15}\leq\dfrac{150}{15}\\\\x\leq10\to x\in(-\infty,\ 10]$
