Find the distance d between 21 = (-7 - 6i) and Z2 = (-15 – 12i). Express your answer in exact terms and simplify, if needed.

dlinn [17]

Answer:

Step-by-step explanation:

The distance is equal to the modulus of Z1-Z2.

$Z_1 - Z_2 = -7 - 6i - (-15 - 12i) = 8 + 6i\\|8 + 6i| = \sqrt{8^2 + 6^2} = \sqrt{64 + 36} = \sqrt{100} = 10$

A raffle prize of 14x^2/15dollars is to be divided among 7x people. Write an expression for the amount of money that each person

vladimir2022 [97]

For this case we must divide the following expression:

$\frac {\frac {14x ^ 2} {15}} {7x}$

And in this way we get the amount of money that each person will receive.

Then applying double C we have:

$\frac {14x ^ 2} {15 * 7x} =\\\frac {14x ^ 2} {105x} =\\0.133x$

Thus, each person has 0.133x of money!

Answer:

0.133x
