Tina is the top seller of the store. She earns a salary plus 2%. Tina's salary is $30,000 a year. This month her sales were $48,
Lilit [14]
I'm assuming she gets 2% commission on sales and that she gets paid monthly from her yearly salary.

If the above is true, her monthly pay is calculated as follows:

Commission: 48500 * 0.02 = $970
Monthly salary: 30000 ÷ 12 = $2500

So monthly pay is $2500 + $970 = $3470

Identify the equation of the circle that has its center at (9, 12) and passes through the origin.
Tcecarenko [31]

Answer:

(x-9)^2 +(y-12)^2 = 225

Step-by-step explanation:

First find the length of the radius

If is the distance from the center to the point

d = sqrt( (x2-x1)^2 + (y2-y1)^2 )

   = sqrt( (0-9)^2 + (0-12)^2)

   = sqrt ( 81+144)

  = sqrt(225)

  = 15

The equation for a circle is

( x-h) ^2+ (y-k)^2 = r^2

(x-9)^2 +(y-12)^2 = 15^2

(x-9)^2 +(y-12)^2 = 225

Answer:

32768

Step-by-step explanation:

<h2><u>SIMPLIFY</u></h2>

\frac{(2^{4} )^5}{2^{5} } \\

<h3>now make use of the exponent rule :</h3>

\frac{x^a}{x^b} = x^{a-b}\\

(\frac{(2^4)^5}{2^5}  = (\frac{2^4}{2} )^5\\

\frac{2^4}{2} = 2^3

=(2^{3} )^5

<h3>apply the exponent rule:</h3>

 (a^{b})^c =  a^{bc}

2^{3*5} \\2^{15}\\

= <u>32768</u>
