Sara's results probably do have a higher mean, if we take into account how William is way more willing to pay 20 dollars. Honestly, I think you got your chosen answers right! Just my opinion, as someone inexperienced.

Can anyone explain how to do this? I looked at the book and now I'm even more confused. 50 points

The piecewise function is basically the result of two different functions combined together. If x is 0 or larger, then h(x) = x+4. Otherwise, if x < 0, then h(x) = -x-4

No matter what number you pick for x, the h(x) function will be used in some way. So the domain is the set of all real numbers. To write this in interval notation, we write (-\infty, \infty) which means we start off at negative infinity and go to positive infinity. This is basically saying "the entire real number line". Since we can't actually reach either infinity, we always use parenthesis with them. <u>Never</u> use square brackets with either infinity

From the graph (see attached image below), we see that (0,-4) is the lowest point. This means y = -4 is the smallest y output possible, though we can't actually reach it because of the open circle at (0,-4). We can get any other larger y value. So the range is therefore: (-4, \infty) meaning we start at -4 and head off to positive infinity. The curve parenthesis next to -4 the reader "exclude -4 as part of the range". There is an open hole or gap here. Another way to state the range is to write y > -4

Answer:

43.94?

Step-by-step explanation:

I think if you use inverse cos you should get the correct number. So, to find cos, you need to know the adjacent side and the hypotenuse. Here, the reference angle would be the person holding the kite. The distance from the person to the barn is the adjacent side, which is 18. The string of the kite, I assume, would be 25.

cos(∅) = \frac{18}{25}

cos(∅) = 0.72

cos⁻¹(0.72) = 43.94

I don't know if that's what you're looking for, but... If it's not correct, lmk so I can rewrite it. :)

WILL GIVE BRAINLIEST!!!
Slav-nsk [51]

\text{Consider the function}\\&#10;\\&#10;f(x)=6x^3-3\\&#10;\\&#10;\text{let }y=f(x), \text{ so we have}\\&#10;\\&#10;y=6x^3-3\\&#10;\\&#10;\text{now in order to find the inverse of the function, first we interchange x and y}\\&#10;\text{so we get}\\&#10;\\&#10;x=6y^3-3

\text{now we will solve for y again and that will give the required inverse function.}\\&#10;\text{so first we add 3 both sides to get}\\&#10;\\&#10;x+3=6y^3\\&#10;\\&#10;\text{now divide both sides by 6 to get}\\&#10;\\&#10;\frac{x+3}{6}=y^3\\&#10;\\&#10;\text{now take cube root both sides to get}\\&#10;\\&#10;\sqrt[3]{\frac{x+3}{6}}=\sqrt[3]{y^3}

\Rightarrow \sqrt[3]{\frac{x+3}{6}}=y\\&#10;\\&#10;\Rightarrow y=\sqrt[3]{\frac{x+3}{6}}\\&#10;\\&#10;\text{hence the inverse of the function is: }\\&#10;\\&#10;f^{-1}(x)=\sqrt[3]{\frac{x+3}{6}}
