Answer:
Step-by-step explanation:
<u>Simplify, rationalize the denominator</u>
- √2/(3 + √5) =
- √2(3 - √5)/(3 + √5) (3 - √5) =
- (3√2 - √10)/(3² - 5) =
- (3√2 - √10)/4
Answer:
257
Step-by-step explanation:
The divisors of 72 which are composite number are
4,6,8,9,12,18,36,72 (composite numbers are those numbers which are formed by the multiplication of two whole numbers}
So the total number of divisors which are composite are = 8
So total number of subset 
In question it is said that also include empty set in count
So total number of subset =256+1=257

5 or more is greater 4 or you give it a rest
Answer:
Step-by-step explanation:
The standard form for the equation of a circle is

From the info given, we have the center, (h, k) as (5, -3) and the x and y coordinates of (2, 5). We will use these to solve for r-squared, then plug back in what we need to write the equation.
which simplifies to
and
so

Filling in the equation:
