Describe this pattern and Find the next 3 numbers in the pattern 3.5, 13, 41.5, 127, , , . also explain in a easy way how you fi

notsponge [240]

You have:

$a_1=3.5,\\ \\a_2=13,\\ \\a_3=41.5,\\ \\a_4=127.$

Find

$a_2-a_1=13-3.5=9.5,\\ \\a_3-a_2=127-41.5=28.5=9.5\cdot 3,\\ \\a_4-a_3=127-41.5=85.5=28.5\cdot 3=9.5\cdot 3^2.$

This gives you the rule how to find next terms:

1.

$a_5-a_4=9.5\cdot 3^3,\\ \\a_5-127=256.5,\\ \\a_5=127+256.5=383.5.$

2.

$a_6-a_5=9.5\cdot 3^4,\\ \\a_6-383.5=769.5,\\ \\a_6=383.5+769.5= 1153.$

3.

$a_7-a_6=9.5\cdot 3^5,\\ \\a_7-1153=2308.5,\\ \\a_7=1153+2308.5=3461.5.$

Answer: next 3 terms are 383.5, 1153 and 3461.5.

Simplify each expression, and classify the result as rational or irrational.<br> HELP

SOVA2 [1]

Expressions $2\sqrt{5}-3\sqrt{5},\frac{\sqrt{42} }{\sqrt{68} } and \sqrt{7}\pi -\sqrt{14} \pi$ are irrational.

Expressions $\frac{5\sqrt{3}-\sqrt{3} }{2\sqrt{3} }$ and $\frac{\sqrt{64} }{32}$ are rational.

Rational and irrational expression :

The given expression are,

$2\sqrt{5} -3\sqrt{5} =\sqrt{5}(2-3)=-\sqrt{5}$

Which is irrational.

$\frac{\sqrt{42} }{\sqrt{68} } =\frac{\sqrt{42} }{2\sqrt{17} }$

Which is irrational.

$\sqrt{5}(4\sqrt{5}-3\sqrt{5}=5$

Which is rational.

$\frac{5\sqrt{3}-\sqrt{3} }{2\sqrt{3} }=2$

Which is rational.

$\frac{\sqrt{64} }{32} =\frac{8}{32}=\frac{1}{7}$

Which is rational.

$\sqrt{7} \pi -\sqrt{14}\pi =\pi (\sqrt{7}-\sqrt{14})$

Which is irrational.

What is Rational expressions ?

Rational expressions represent the relationship between two polynomials. It means that the numerator and denominator are both polynomials.
It is an algebraic expression ratio with an unknown variable, similar to a fraction. We can, however, simplify this type of expression with the aid of a calculator.
You've probably heard of rational numbers, which are written in the form p/q. In contrast, rational expressions are the ratio of two polynomials.
To find the root or zero of a polynomial expression, we must first make it equal to zero. To find the zeros of rational functions or expressions, however, only the numerator must be set to zero after the expression has been reduced to its simplest terms.

How many ways are there to paint a set of 27 27 elements such that 7 7 are painted white, 6 6 are painted old gold, 2 2 are pain

Alexeev081 [22]

Answer:

There are 2,480,721,300,000,00 ways to paint this set.

Step-by-step explanation:

We have that:

A set of 27 elements, of which:

7 are painted white

6 are painted old gold

2 are painted blue

7 are painted yellow

5 are painted green

How many ways are there to paint?

A single change in the set, for example, element 0 exchanged with element 1, means we have a new way. So we use the permutations formula to solve this problem:

Permutations

Permutations of a set of x elements divided into sets of size w,y,z.

The number of ways is:

$P{x}_{w,y,z} = \frac{x!}{w!y!z!}$

In this problem, we have that:

A set of 27 divided into sets of 7,6,2,7,5. So

$P{27}_{7,6,2,7,5} = \frac{27!}{7!6!2!7!5!} = 2,480,721,300,000,00$

There are 2,480,721,300,000,00 ways to paint this set.

Answer:

1.36

total cans =11

the prob. of drawing orange juice can= 4/11

the prob of drawing apple juice can= 7/11

the prob of drawing any of the juice= 4/11 + 7/11

= 15/11

= 1.36
