Mandarinka [93]

Answer:

Step-by-step explanation:

We are here given a modulus expression and we need to find out the value when m = -5 and n = 3 .

Modulus :- It always gives positive value . For example ,

$\rm\implies |-a| = a$

$\rm\implies |a| = a$

The given modulus expression is :-

$\rm\implies |m^2+ n^2|$

As the number inside the modulus operator are already squared therefore they will always give positive value for real numbers . Here we can omit the modulus .

$\rm\implies m^2 + n^2$

Plug in the given values ,

$\rm\implies (-5)^2 + 3^2$

Solve 5² and 3² and add them ,

$\rm\implies 25 + 9$

On adding ,

$\rm\implies 34$

Therefore ,

$\rm\implies \boxed{\blue{\rm |m^2+n^2| = 34 }}$

Hence the required answer is 34 .

Answer:

Company 2 because it is gaining six times the number of employees, while Company 1 is only adding 6 employees every year.

Step-by-step explanation:

Looking at the table, the number of employees in Company 1 goes up by 6 employees per year.

The number of employees in Company 2 is multiplied by 6 every year; this means they gain more employees after the first year than Company 2 does (they go from 6 to 36, which is a gain of 30, while Company 1 goes from 6 to 12, a gain of 6).

If we are looking strictly at the number of employees, Company 2 is the better choice.

2+3=5 so 35/5 =7

7x2 means she used 14 litres of fruit juice

7x3 means she used 21 litres of lemonade
