1. Bill decided to buy six books on history instead
bulgar [2K]

Answer: 2/3 books on politics

Step-by-step explanation:

The opportunity cost of something is the next best alternative that you would have taken if you did not instead go for the option that you took.

Opportunity cost here is the number of books on politics that Bill had to give up to get a single book on history.

= Number of politics books / Number of history  books

= 4 / 6

= 2/3 books on politics

<em>Bill gave up 2/3 books on politics to get a single history book. </em>

Thanks for the help!
NikAS [45]

Answer:

A

Step-by-step explanation:

So we have the piecewise function:

f(x)= \begin{cases}\sqrt{2x} & \text{if }x

And we want to find f(8).

Since our input value is 8, choose the equation that fits our input.

The first equation demand x to be less than 3. 8 is not less than 3, so we won't use that.

The second equation demand x to e greater than or equal to 3 and less than 8. 8 is <em>not</em> less than 8. So, we won't use that.

The third equation demands x to be greater than or equal to 8. 8 is greater than or equal to 8, so we'll use the third equation.

So:

f(x)=42\text{ if }x\geq 8

f(8)=42

There're nothing more to do, we're done :)

The answer is A.

If (5-3i)(x+iy)/(4-5i) = (2+i)^2-(3-4i)^2, then x=___ and y=____
Leona [35]
This looks complicated

lets simplify both sides

By multiplying top and bottom by the conjugate:-

left side  =  (5-3i)(x + iy) (4+5i)          (5-3i)(x + iy) (4+5i) 
                  ------------------------   =      ------------------------
                        (4-5i)(4+5i)                           41

right side =  (2 + i + 3-4)(2+i - 3 + 4i)    (by  Difference of 2 squares)

               =  5-3i)(-1 + 4i)

so as left side = right side

(5-3i)(x+yi)(4+5i)   = 41 (5-3i)(-1+5i)

5-3i is common so:-

(x + iy)(4+5i) = 41(-1+5i)

4x +5xi + 4yi - 5y = -41 + 205i

4x - 5y + (5x + 4y)i = -41 + 205i

EQuating coefficients we are left with the system of equations

4x -  5y = -41
5x + 4y  = 205

solving this gives x = 21 and y = 25
