P and q are complex numbers such that |p|=7√2 and |p+q|=12√3 .
gayaneshka [121]

Answer:

Option B is correct

Step-by-step explanation:

Given: \left | p \right |=7\sqrt{2}\,,\,\left | p+q \right |=12\sqrt{3}

To find: interval on which \left | q \right | must fall

Solution:

\left | p \right |=7\sqrt{2}\\-7\sqrt{2}\leq p\leq 7\sqrt{2}\,\,(i)

\left | p+q \right |=12\sqrt{3}\\-12\sqrt{3}\leq p+q\leq 12\sqrt{3}\,\,(ii)

Subtract (ii) from (i)

-12\sqrt{3}+7\sqrt{2}\leq p+q-p\leq 12\sqrt{3}-7\sqrt{2}\\-12\sqrt{3}+7\sqrt{2}\leq q\leq 12\sqrt{3}-7\sqrt{2}\\\left | q \right |=12\sqrt{3}-7\sqrt{2}

So, \left | q \right | must fall in interval [12\sqrt{3}-7\sqrt{2},\infty)

Therefore, option B is correct.

where

m is the slope

b is the y-intercept or initial value

Let

y ----> total weekly pay

x ---> is the number of computers sold in a week

In this problem we have

m=\$30\ per\ computer\ sold
