Answer:

Last week, she earned a total of $702 last week in commission.

Step-by-step explanation:

To solve this, we first need to find 13% of $5,400.

5,400 x 0.13 = 702

Therefore, Nadia earned a total of $702 last week in commission.

Now, we need to calculate how much money she'll earn in a whole year. So, let's see how many weeks are in a year.

1 year = 52 weeks when rounded to the nearest whole number

702 x 52 = $36,504

Therefore, Nadia earned a total of $36,504 in commission in 2011.

Hope this helps! :D

Rewrite the expression as a product of two factors. 72t+8

Aneli [31]

Step-by-step explanation:

The above given expression "72t+8 " have to be factorized by the following methods.

Step 1 :

First we must check both numbers in order to obtain common factor for both ,for this equation "8" is the common factor for both .

Step 2:

After obtaining the common factor for the equation equation, we must now take the factor as common outside the bracket and form the equation as follows,

⇒ 8 * ( 9*t + 1 )

Here there are the two factors for the equation " 72 t+ 8 " that are 8 and 9t+1.

Step 3 (optional) :

Now check weather the factors are correct or not by multiplying factors with each other.

Multiplying ,

⇒ 8 * ( 9*t + 1 )

Gives -

⇒ 72 t+ 8

Find the missing coefficients y=ax^2-10x+c vertex :(-5,20)

Citrus2011 [14]

Remember, for $y=ax^2+bx+c$ the x value of the vertex is $\frac{-b}{2a}$

so
given
x value of vertex is -5
and
$y=ax^2-10x+c$
$\frac{-b}{2a}=\frac{-(-10)}{2a}=\frac{10}{2a}=$
$\frac{5}{a}=-5$
multiply both sides by a
5=-5a
divvide both sides by -5
-1=a
a=-1

$y=-1x^2-10x+c$
comlete the square
remember if we do
$y=a(x-h)^2+k$ (h,k) is the vertex
I know, we can subsitute the known values of te vertex
-5 for h and 20 for k then expand

$y=-1(x-(-5))^2+20$
$y=-1(x+5)^2+20$
$y=-1(x^2+10x+25)+20$
$y=-1x^2-10x-25+20$
$y=-1x^2-10x-5$

a=-1
c=-5
