Answer:
(x - 7)² + (y + 2)² = (2√13)²
Step-by-step explanation:
We already know that the center is at (7, -2), but must find the radius. The radius is the distance between the points (7, -2) and (1, -6):
r = √ [6² + 4²] ) = √(36 + 16) = √52 = √4√13 = 2√13.
Then the desired equation is (x - 7)² + (y + 2)² = (2√13)²
(4)x5 is the same as (4)5 or 4 x 5
it equals 20
It is a good thing to remember. Of course, not all, but some basic numbers that appear all the time such as the numbers from 2 to 13 should be remembered as they appear in numerous assignments and tests.
11/15-2/5
Multiply 2 and 5 to get a common denominator of 15
11/15-6/15
=4/15
Solutions
We know that <span>Function 1 shows a greater rate of change, because Maddy spends $20 each month and Caitlin spends $18.
</span>
Maddy spends 2 dollars more.
Therefore the correct answer is the last option.
