Answer:

  • (3√2 - √10)/4

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

How many subsets of the set of divisors of 72 contain only composite numbers? For example, {8,9} and {4,8,12}$ are two such sets
kykrilka [37]

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 =2^n=2^8=256

In question it is said that also include empty set in count

So total number of subset =256+1=257

Give the equation of the circle whose center is (5 -3) and goes through (2 5)
Alekssandra [29.7K]

Answer:

Step-by-step explanation:

The standard form for the equation of a circle is

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

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.

(2-5)^2+(5-(-3))^2=r^2 which simplifies to

(-3)^2+(8)^2=r^2 and

9+64=r^2 so

r^2=73

Filling in the equation:

(x-5)^2+(y+3)^2=73
