saul85 [17]

Answer:

$85

Step-by-step explanation:

To find the answer, we need to divide 1,615 by 19, since it says he earned 19 times the amount last year.

1,615/19=85

He only earned 85 dollars last year.

Hope this helps!

What are the remaining trig functions? and how do i solve for them? pls help

You're told that tan(<em>θ</em>) is positive, but

tan(<em>θ</em>) = sin(<em>θ</em>)/cos(<em>θ</em>)

and you're also told that sec(<em>θ</em>) = 1/cos(<em>θ</em>) = -3. So if cos(<em>θ</em>) is negative, sin(<em>θ</em>) must also be negative. In turn, both sec(<em>θ</em>) = 1/cos(<em>θ</em>) and csc(<em>θ</em>) = 1/sin(<em>θ</em>) are also negative.

Now, recall the Pythagorean identity,

cos²(<em>θ</em>) + sin²(<em>θ</em>) = 1

Multiply through both sides by 1/cos²(<em>θ</em>) to get an alternate form of the identity,

1 + tan²(<em>θ</em>) = sec²(<em>θ</em>)

Solve for tan(<em>θ</em>) (which we know is positive):

tan(<em>θ</em>) = √(sec²(<em>θ</em>) - 1) = 2√2

Right away, we get

cot(<em>θ</em>) = 1/tan²(<em>θ</em>) = 1/(2√2) = √2/4

Since sec(<em>θ</em>) = -3, it follows that cos(<em>θ</em>) = -1/3.

Then

tan(<em>θ</em>) = sin(<em>θ</em>)/cos(<em>θ</em>)   ==>   sin(<em>θ</em>) = 2√2 × (-1/3) = -2√2/3

and so

csc(<em>θ</em>) = 1/sin(<em>θ</em>) = -3/(2√2)

inessss [21]

Answer:

Roxana's normal hourly pay is $12

Step-by-step explanation:

overtime pay=p

normal hourly rate=r

p=1.5r

72/4=18

p=$18/hr

p=1.5r

18/1.5=1.5r/1.5

<u>12=r</u>
