Which formula gives the x-coordinates of the maximum values for y = cos(x)?

REY [17]

Answer with explanation:

The given trigonometric Function is,

y= cos x

→The maximum value of , cos x , is 1, at x=0 degree.

Cos x =1

→Cos x = Cos (0)degree,

$x=2 k \pi \pm 0$

→ for, k= An Integer

x=2 k π→→General formula that gives the x-coordinates of the maximum values for y = cos(x)

Ordered Pair =(x,y)=(2 k π, 1)

For, any value of , k in the given equation, y will be always 1.

Peter works at Silly's and makes $33.19 an hour. He also collects a 5.3% commission on final weekly sales. Last month, he worked

Romashka-Z-Leto [24]

Answer:

$10,318.62

Step-by-step explanation:

We have been given that works at Silly's and makes $33.19 an hour. He also collects a 5.3% commission on final weekly sales. If he works over 40 hours during any week, he earns double his hourly wage.

Peter's hourly charges during 1st and 2nd week would be $33.19 and hourly charges during 3rd and 4th week would be 2 times $33.19.

First of all, we will find total hourly income as:

$\text{Total hourly income}=\$33.19(30+40)+2\times \$33.19(49+55)$

$\text{Total hourly income}=\$33.19(70)+\$66.38(104)$

$\text{Total hourly income}=\$2323.3+\$6903.52$

$\text{Total hourly income}=\$9226.82$

Now, we will find income from commission on sales as:

$\text{Income from commission on sales}=\frac{5.3}{100}(4500+5500+3800+6800)$

$\text{Income from commission on sales}=0.053(20600)$

$\text{Income from commission on sales}=1091.8$

Peter's total earnings is the last month: $\$9226.82+\$1091.8=\$10,318.62$

Therefore, Peter's total earnings in last month was $10,318.62.
