Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.

The amplitude of sin(x) is 1, so we want

sin (2x) =1

taking inverse sin, we get
2x = $\pi /2$

divide by 2 and we get
x = $\pi /4$

Raul has been offered three different jobs and must choose which one to accept. One of the factors he is considering is the pay

chubhunter [2.5K]

Answer:

As the pay rate for Job C is the highest, so he must accept the offer from Job C.

Step-by-step explanation:

Given that Raul would work 50 weeks of the year,

40 hours each week,

5 days each week,

and he would receive a 1-hour lunch break each day.

Pay rate for Job A = $35,000 / year

For Job B:

Pay rate = $15 / hour

He will work 40 hours each week.

As he works 5 days a week, so in 1 day he will work 40/5 = 8 hours.

He would receive a 1-hour break each day, for which he will not be paid, so he will receive a payment for 8-1=7 hours.

So, payment for 1 day = $15 x 7 = $105

As he works 5 days a week, so payment for 1 week = $105 x 5 = $525

As he works 50 weeks a year, so payment for 1 year = $525 x 50 = $26250.

So, the pay rate by Job B = $26250 /year

For Job C:

Pay rate = $750 / week

As he works 50 weeks a year, so payment for 1 year = $750 x 50 = $37500.

So, the pay rate by Job C = $37500 /year

As the pay rate for Job C is the highest, so he must accept the offer from Job C.

David will spend at most $39 on gifts. So far, he has spent $22. What are the possible additional amounts he will spend? Use c f

iren2701 [21]

Answer:

$c\leq \$17$

Step-by-step explanation:

Let

c -----> the additional amount (in dollars) David will spend

we know that

The word " at most" in this context means "less than or equal to"

The amount David has spent plus possible additional amounts he will spend must be less than or equal to $39

The inequality that represent this situation is

$22+c\leq 39$

solve for c

subtract 22 both sides

$c\leq 39-22$

$c\leq \$17$

The maximum amount he could spend is $17
