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.

Josh works as a tutor for $9 an hour and as a waiter for $8 dollars an hour. This month, he worked a combined total of 101 hours
katovenus [111]
<h3>Answer:   9t+8(101-t)</h3>

Work Shown:

t = number of hours tutoring

101-t = number of hours working as a waiter

The expressions t and 101-t add to 101.

9t = amount earned as a tutor, at $9 an hour

8(101-t) = amount earned as a waiter, at $8 an hour

9t+8(101-t) = total amount earned from both jobs

This does not account for taxes or other fees. Optionally, you can distribute the 8 through the (101-t) terms, then combine like terms to simplify.
