PART A:
x | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 |
y | 6 | 5.5 | 5 | 4.5 | 4 | 3.5 | 3 | 2.5 | 2 | 1.5 | 1 | 0.5 | 0 |

x=hours
y=candle length

PART B:
Yes it is a function because you can input the values

PART C:
Yes, it will still be a function but with a different different y value

Jaime is playing disc golf. He is standing across a creek from the basket at a 60° angle.

Alja [10]

<h3>The equation used to find the distance, r, between him and the basket is:</h3>

$tan\ 60 = \frac{r}{5}\ meters$

<em><u>Solution:</u></em>

Given that,

Jaime is playing disc golf

He is standing across a creek from the basket at a 60° angle

Let "r" be the distance between him and the basket

The figure is attached below

From figure, it is a right angled triangle

By definition of tan,

$tan\ 60 = \frac{opposite}{adjacent}$

From figure,

opposite = r

adjacent = 5 m

$tan\ 60 = \frac{r}{5}$

Thus the equation used to find the distance, r, between him and the basket is found

One of the legs of a right triangle measures 17 cm and the other leg measures 5 cm. Find the measure of the hypotenuse. If neces

Semenov [28]

Answer:

17.7 cm^2

Step-by-step explanation:

The formula for finding the hypotenuse using the pythagorean theorem is:

$a^{2}+b^{2}=c^{2}$

or, it can also be $c=\sqrt{a^2+b^2}$ . But I will be using the first formula.

We first plug in the "legs" to the equation:

$a^{2} =17^{2} \\b^{2}=5^2$

$17^2+5^2=c^2\\17^2+5^2=314$

Now, you find the square root of 314.

$\sqrt{314}=17.72^2$

And finally, just round to the nearest tenths place!

$17.7^2$

For this question, use the following functions.

Lubov Fominskaja [6]

Answer:

4x + 18

Step-by-step explanation:

This is called a composite function, meaning passing the range of one function as a domain of another function.

For f(f(x)), the inner-function's range is passed as the domain of the outer function.

We can do so by substitution,

The range of f(x) can be written as 2x + 6 for any defined x values,

So we will substitute 2x + 6 as the 'x' of another function which is in this case

f(x) again, so it looks like this 2(2x+6) + 6 which can be simplified into

4x + 18
