How do you convert set notation to interval notation?
Semenov [28]

Answer:

Imagine we are to express  [ a , b ]  in set notation

A = [ a , b ] , then  A = { x  ∈  R  /  a ≤ x ≤ b }

In this notation we define the characteristics of all  x  belonging to this set  A ....x must be greater or equal to a and simultaneously smaller or equal to b...

Interval notation is other way to say the same but assuming that  means the extreme a is IN the interval and  means extreme  a  is not.

On the first visit to the veterinarians office chorus kitten weighed 550 g on the second visit the kitten had ganged 350 g on th
Roman55 [17]

Answer:

<em></em>\%Increase = 118\%<em></em>

<em></em>

Step-by-step explanation:

Given

Initial\ Weight = 550g

First\ Addition = 350g

Second\ Addition = 300g

Required

Determine the percentage increment

First, we have to calculate the new weight

New\ Weight = Initial\ Weight + First\ Addition + Second\ Addition

New\ Weight = 550g + 350g + 300g

New\ Weight = 1200

The percentage increment is then calculated as:

\%Increase = \frac{New\ Weight - Initial\ Weight}{Initial\ Weight} * 100\%

\%Increase = \frac{1200g - 550g}{550g} * 100\%

\%Increase = \frac{650g}{550g} * 100\%

\%Increase = \frac{650}{550} * 100\%

\%Increase = 1.182* 100\%

\%Increase = 118.2\%

<em></em>\%Increase = 118\%<em> -- Approximated</em>

<em></em>

<em>Hence, the percentage increment is approximately 118%</em>

Multiply. √3 ⋅ 2√2 ⋅ 5√8 ⋅ √18 Enter your answer, in simplest radical form, in the box.
kenny6666 [7]

Answer:

120√6

Step-by-step explanation:

Simplify the 5√8 to 2√2

simplify the √18 to 3√2

so it would be √3 * 2√2 * 5 * 2√2 * 3√2

when a square root of an expression is multiplied by itself:

√3 * 2 * 2* 5 * 2 * <em>3</em>√2

so as we calculate it, 2 * 2* 5 * 2 * <em>3</em> = 120 and √2 * √3 = 6
