Paul can choose to be paid $50 for a job or he can be paid $12.50 per hour Under what circumstances should he choose the hourly wage?Explain

12.50 x 4 hours = $50

Step-by-step explanation:

It is advisable to pick the hour based form of payment because this gives room for flexibility in terms of time scheduled for the work.

Also, if the hourly based rate of $12.50 is chosen, this means he only have to work for 4 hours to break even with $50 ( 4hours x $12.50 = $50).

Hence, Paul is advised to pick the hourly based payment if he plans to work for more than 4 hours.

Nevertheless, if he plans to work for less than 4 hours, he is advised to go for $50 payment schedule.

The reason for choosing the hourly pay is that $12.50 paid per hour means if he works for 24 hours,the pay will be $12.5×24=$300...

Which means he will surely earn more by working hourly compared to working being paid $50.

The difference between the $50 and the hourly pay is so much that he will rather go for the highest pay.

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

                  = 2×(-2)+(-8)×(6)+(-8)×(-5)

                  = -4-48+40

                  = -12

hence, v.w= -12
