Answer:

- 10√2 - 5√5

Step-by-step explanation:

- 2√50

√50 = √( 2 x 5 x 5 ) = 5√2

- 2√50

= - 2 x 5√2

= - 10√2

- √125

= - √( 5 x 5 x 5 )

= - 5√5

- 2√50 - √125

= - 10√2 - 5√5

Answer:

Step-by-step explanation:

50: 2 * 5 * 5

125:5 * 5 * 5

sqrt(50) = 5*sqrt(2)  For every pair of primes, 1 of them is put outside the sqrt sign and one is discarded.

sqrt(125) = 5*sqrt(5) Same rule.

-2 sqrt(50) - sqrt(125)

-2*5*sqrt(2) - 5sqrt(5)

Answer: -10*sqrt(2) - 5sqrt(5)

You could write the answer as

Answer: -5(2sqrt(2) + sqrt(5) )

Comment: I don't know which answer you should use. I think the second one is more complete, but your marker may not agree.

Sin^2x/cos^2 + sinxcscx = sec^2x Identify it, please explain so I know how you did it, thanks
max2010maxim [7]

\frac{sin^2x}{cos^2x} + sin x *cscx\\ tan^2x + \frac{sin x}{sin x} \\ tan^2x + 1\\ sec^2x

\frac{sin^2x}{cos^2x} = tan^2x

csc x = \frac{1}{sinx}

tan^2x + 1 = sec^2x

A presidential candidate plans to begin her campaign by visiting the capitals in 44 of 5050 states. what is the probability that
defon
Part A:

Given that <span>A presidential candidate plans to begin her campaign by visiting the capitals in 4 of 50 states.

The number of ways of selecting the route of 4 specific capitals is given by

^{50}P_4= \frac{50!}{(50-4)!} =  \frac{50!}{46!} =50\times49\times48\times47=5,527,200

Therefore, the probability that she selects the route of four specific​ capitals is \frac{1}{5,527,200}



Part B:
</span>
<span>The number of ways of selecting the route of 4 specific capitals is 5,527,200.

Since </span><span>the number of ways of selecting the route of 4 specific capitals is too large it is not practical to list all of the different possible routes in order to select the one that is​ best.

Therefore, "</span><span>No, it is not practical to list all of the different possible routes because the number of possible permutations is very large."</span>
