Help!!!!!!!!!!!! &gt;&gt;&gt;&gt;&gt;Which number set contains all rational<br> numbers?
stellarik [79]

The only set that only has rational numbers is the first one:

{1/3, -3.45, √9}

<h3>Which of the given sets contains only rational numbers?</h3>

A rational number is a number that can be written as the quotient of two integers.

If we look at the first set, the elements are:

  • 1/3 which is a rational number.
  • -3.45 = -345/100 which is a rational number
  • √9 = 3 = 3/1 which is a rational number.

In the other sets we can see elements like:

√37, √44, or √2 which are all irrational numbers, then the only correct option is the first one.

y is directly proportional to the positive square root of x when x = 9, y= 12 find y when x =1/2​
ehidna [41]

Y =k√x

12 = 3k

k = 4

now X = 1\2

y = 4√1/2

y = 2√2

Answer:

• changing an interior angle to a reflex angle

Step-by-step explanation:

In order for the outline of the polygon to have a pair of sides that is concave (pointed inward, rather than outward), the corresponding interior angle must be a reflex angle. (It must measure more than 180°.) Draw one; you'll see.

First, you should solve for f(2x), which equals 2*(2x)=4x.  Now, solve the integral of f(2x)=2*(2x)=4x, to get that\int\ {(f(2x)=4x)} \, dx= 2x^2.  You can check this by taking the integral of what you got.  Now by the Fundamental Theorem\int\limits^2_0 {4x} \, dx=[2x^2] ^{2}_{0}=2(2)^{2}-2(0)^2=8.

This should be the answer to your question, if I understood what you were asking correctly.
