nadia is a stockbroker. she earns 14% commission each week. last week, she sold $4 comma 500 worth of stocks. how much did she make last week in commission? if she averages that same amount each week, how much did she make in commission in 2011?

Multiply the amount she sold by the percent of commission:

4500 x 0.14 = 630

She made $630 last week.

There are 52 weeks in a year, multiply the amount of commission by 52:

630 x 52 = 32760

She made $32,760 in 2011.

Nadia won last week:

If the year is considered to be approximately 52 weeks, it could be said that Nadia won in 2011:

Step-by-step explanation:

Since Nadia is known to earn 14% commission, having sales of $ 4500, you only have to multiply this value by the percentage of profit:

Now, if you consider that you always earn the same weekly amount and it is taken that the year has 52 weeks (in fact they are 52.14 weeks, but it is better to work with whole numbers), you must multiply the number of weeks by the amount earned by last week:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
