Thomas has been offered two jobs. The first job pays $880.00 per week. The second job pays $790.00 per week plus 12% commission

LUCKY_DIMON [66]

Answer:

he has to make a sale of $750

Step-by-step explanation:

first job pays $880 per week

second job pays $790 per week

amount first job is paying more=$(880-790)

=$90

therefore,12% should $90 if he wants to make an equal amount as the first job is paying therefore,sale he has to do

12% of x=$90

12/100*x=$90

x=90*100/12

x=9000/12

x=$750

thus he has to make a sale of $750 to earn a 12% comission of $90

In the diagram below, assume that all points are given in rectangular coordinates. Determine the polar coordinates for each poin

Korolek [52]

Step-by-step explanation:

We have cartisean points. We are trying to find polar points.

We can find r by applying the pythagorean theorem to the x value and y values.

$r {}^{2} = {x}^{2} + {y}^{2}$

And to find theta, notice how a right triangle is created if we draw the base(the x value) and the height(y value). We also just found our r( hypotenuse) so ignore that. We know the opposite side and the adjacent side originally. so we can use the tangent function.

$\tan(x) = \frac{y}{x}$
