A circle has a radius of 7/4 units and is centered at <br> (−2.5,−4.4)

lana66690 [7]

Are you asking for the expression?

If so, you plug into the format (x - h)² + (y - k)² = r² where (h, k) is the center and r is the radius.

(x + 2.5)² + (y + 4.4)² = (7/4)²

Simplify to get your equation and answer:

(x + 2.5)² + (y + 4.4)² = 49/16

Jana joined a music club that offered her 5 CDs for a total of 3.00 if she agreed to purchase an additional 10 CDs for 15.00 eac

Hunter-Best [27]

Answer:

Average price, excluding taxes, for each CD is <u>10.20</u>.

Step-by-step explanation:

Given:

Cost of first 5 CDs, $C_1 = 3.00$

Cost of each additional CD = 15.00

Now, cost of 10 additional CDs is the product of cost of one CD and total number of additional CDs. Therefore,

Cost of 10 additional CDs is, $C_2=15.00\times 10=150.00$

Now, total CDs purchased by Jana are, $N=5+10=15$

Total cost of the 15 CDs purchased is given as:

$C_T=C_1+C_2=3.00+150.00=153.00$

Now, average price, excluding taxes, for each CD is given as:

$\textrm{Average price}=\frac{\textrm{Total cost of purchase}}{\textrm{Total number of CDs purchased}}\\\\\textrm{Average price}=\frac{C_T}{N}=\frac{153.00}{15}=10.20$

Therefore, the average price, excluding taxes, for each CD is 10.20.
