Find the slant height of the cone.

sammy [17]

Answer:

The slant height is $13m$

Step-by-step explanation:

The slant height of the cone, $l$ , can be found using Pythagoras Theorem.

$l^2=12^2+(\frac{10}{2})^2$

$l^2=12^2+(5)^2$

$l^2=144+25$

$l^2=169$

$l=\sqrt{169}$

$l=13m$

If 32 teams participate in a standard single elimination tournament, how many games must be played to decide a champion?

SCORPION-xisa [38]

<h3>Answer: 31 games</h3>

======================================================

Explanation:

32/2 = 16 games will happen in round 1. Afterward, 16 teams are left.
16/2 = 8 games will happen in round 2. Afterward, 8 teams are left.
8/2 = 4 games happen in round 3.
4/2 = 2 games in round 4.
2/2 = 1 game as the final championship.

Count the number of times you divide by two and we have five occurrences of this. So there five rounds overall.

To get the total number of games played, we add up the quotients

16+8+4+2+1 = 31

----------------

Or as a shortcut we can simply subtract off 1 since 1+2+4+...+2^n = 2^(n+1)-1

We can write that rule as

$\displaystyle \sum_{k=1}^{n}2^k = 2^{n+1}-1$

which is equivalent to

$\displaystyle \sum_{k=1}^{n}2^{k-1} = 2^n-1$

3x-4y=-5 y=4x-2 Is (1,2) a solution of the system?

Orlov [11]

If you want to check if (1,2) is a solution to the system, you have to plug the x and y values back into both equations. If they work for one equation, but not the other, than the coordinates are not a solution to the system.

3(1) - 4(2) = -5
3 - 8 = -5
-5 = -5

2 = 4(1) - 2
2 = 4 - 2
2 = 2

Since both of these checks are true, then (1,2) is a solution to the system.
