Which of these functions has an inverse function? Select all that apply.

Goshia [24]

So we want to know which of the following functions has an inverse function. So an inverse function is a function that "reverses" another function. We need to put y instead of x and x instead of y. So for the first case: y=x is x=y so this function has an inverse function. y=x^2 is x=y^2 so y=sqrt(x). y=x^3 is x=y^3 so y=∛x. y=x^4 so x=y^4, y=4√x or forth root of x. So all of our functions have an inverse function.

Sin=oposite side/hyptoonuse
Cos=adjacent side/hypotonuse
Tan=oposite side/hypotonuse

oposite side is the side oposite the angle
adjacent side is the side touching the angle that isn't the hypotonuse
hypotonuse is longest side

1.
first solve for hypotonuse using a²+b²=c²
hypotonuse=13
sinA=12/13
cosA=5/13
tanA=12/5
sinB=5/13
cosB=12/13
toa=5/12

2. the missing side is 8
sinD=15/17
cosD=5/17
tanD=15/5=3
sinE=5/17
cosE=15/17
tanE=5/15=1/3

3. missing side is 25
you should be able to do this
sinG=7/25
do the rest

4.
missing side is 6
sinJ=6/10=3/5
do the rest

Suppose you bought a pizza for $8.00. You also bought a salad but you can not remember how much you paid and you can not find th

Darina [25.2K]

The best equation would be A.

with A you get to calculate what is the value of $.

8 + $ = 10 (10 is the total value of your receipt and 8 is the price of pizza)
$ = 10 - 8 (we transfer the price of pizza on the other side to the total amount of your receipt and calculate the remaining amount)
$ = 2

We see that the remaining amount is 2$, which means the salad cost s2$ :)

The reyes family but for concert tickets for $252 what was the price per ticket

Bas_tet [7]

If you mean "The Reyes Family bought for concert tickets for $252",

Consider the total price is $252 and that there are four tickets. You are looking for the price of one ticket so view it as

Total Price = $252
Total Tickets = 4

Total Price divided by Total Tickets =
$\frac{252}{4}$
Then divide both sides by four because 4 divided by 4 is 1 ticket.
$\frac{252 \div 4}{4 \div 4} = \frac{63}{1}$

Then you should get 63 divided by 1.
63 divided by 1 is 63, So your answer is

"The price of one ticket that the Reyes Family bought is 63 dollars."
