This is the math section but ok
if yo mean the pyramid shaped thingie then

get a square piece of paper (4 right angles, equal length sides)
fold the paper in half so one corner touches the opposite corner
unfold
repeat but with the other corner that doesn't ahve a crease
unfold
you should have an x in the middle of the paper with 2 valleys facing up
now fold the 4 corners to the middle of the x so you have a smaller square now
flip it over so the flat side is facing you
fold the 4 corners in to the center
fold the square into a valley horizontally
unfold
fold the square into a valley vertically
unfold
flip it over and pry out the 4 corners and manipulate it like in the illustration

Find the value of r so the line that passes through each pair of points has the given slope.

3241004551 [841]

Answer:

r = 1

Step-by-step explanation:

slope = change in y / change in x, so:

change in y / change in x = 2/3

5 - r / 7 - 1 = 2/3

5 - r / 6 = 2/3

$\frac{5-r}{6}=\frac{2}{3}$

now solve this equation.

first, multiply both sides by 6 to get rid of the fraction:

$5 - r = 4$

subtract 5 from both sides

$-r=-1$

multiply both sides by -1

$r=1$

How do you determine where f(x)=cos^(-1)(lnx) is continuous?

olga nikolaevna [1]

$\ln x$ is continuous over its domain, all real $x>0$ .

Meanwhile, $\cos^{-1}y$ is defined for real $-1\le y\le1$ .

If $y=\ln x$ , then we have $-1\le \ln x\le1\implies \dfrac1e\le x\le e$ as the domain of $\cos^{-1}(\ln x)$ .

We know that if $f$ and $g$ are continuous functions, then so is the composite function $f\circ g$ .

Both $\cos^{-1}y$ and $\ln x$ are continuous on their domains (excluding the endpoints in the case of $\cos^{-1}y$ ), which means $\cos^{-1}(\ln x)$ is continuous over $\dfrac1e$ .

Augustin has 20 different chess boards. If he played 3 games per day, each game played on a different board, how long would it t

Nutka1998 [239]

Answer:

514 days

Step-by-step explanation:

We use the formula (r+n-1)/r(n-1)

There are 1540 combinations. Then, we'll divide them by three because were not just finding the amount of combinations, but the time it'd take to play them all.

We get 513.333(cont.)

thats not really possible, so we're gonna go with 514 instead, rounding up. Normally we'd round down, because the number behind the decimal is below 5, but we really want to make sure we get every combination in there.

Hope this is helpful!
