Answer:

x² + y² = 6.25

Step-by-step explanation:

The standard equation of a circle is ( x – h)² + ( y - k)² = r² where the center is (h, k) and r is the radius.

From your given information that the center is (0, 0) then both h and k are 0. Then r is 2.5, so

( x – 0)² + ( y - 0)² = (2.5)²

x² + y² = (2.5)²

x² + y² = 6.25

An online photo services charge $20 to make a photo book with 16 pages each extra page cost a dollar 75 the cost to ship the com
Alisiya [41]

Answer:

The expression to determine the total cost in dollars is y=25+0.75x.

Step-by-step explanation:

Given:

Service charge to make a photo book = $20

Cost per extra page = $0.75

Cost to ship the complete photo book = $5

We need to write expression to determine the total cost in dollars.

Solution:

Let the number of extra pages be denoted by 'x'.

Also Let the Total cost be denoted by 'y'.

Now we can say that;

Total cost will be equal to sum of Service charge to make a photo book and  Cost per extra page multiplied by number of extra pages and Cost to ship the complete photo book.

framing in equation form we get;

y=20+0.75x+5\\\\y=25+0.75x

Hence the expression to determine the total cost in dollars is y=25+0.75x.
