Choose the correct Set-builder form for the following set written in Roster form: { − 3 , − 2 , − 1 , 0 , 1 }

ohaa [14]

The correct Set-builder form of the set that is written in Roster form is {x|x is an integer and -3≤x≤1}.

<h3>What is an integer?</h3>

An integer is a number that can be written without using a fractional component. Integers such as 21, 4, 0, and 2048 are examples.

The correct Set-builder form of the set that is written in Roster form can be written as,

{x|x is an integer and -3≤x≤1}

Hence, The correct Set-builder form of the set that is written in Roster form is {x|x is an integer and -3≤x≤1}.

The ideal width of a safety belt strap for a certain automobile is 6 cm. The actual width can vary by at most 0.45 cm. Write an

OlgaM077 [116]

Answer:

$|x-6|\le 0.45$

$x\in [5.55,6.45]$

Step-by-step explanation:

<u>Absolute Value Inequality</u>

Assume the actual width of a safety belt strap for a certain automobile is x. We know the ideal width of the strap is 6 cm. This means the variation from the ideal width is x-6.

Note if x is less than 6, then the variation is negative. We usually don't care about the sign of the variation, just the number. That is why we need to use the absolute value function.

The variation (unsigned) from the ideal width is:

$|x-6|$

The question requires that the variation is at most 0.45 cm. That poses the inequality:

$|x-6|\le 0.45$

That is the range of acceptable widths. Let's now solve the inequality.

To solve an inequality for an absolute value less than a positive number N, we write:

$-0.45\le x-6 \le 0.45$

This is a double inequality than can be easily solved by adding 6 to all the sides.

$-0.45+6\le x \le 0.45+6$

Operating:

$5.55\le x \le 6.45$

That is the solution in inequality form. Expressing in interval form:

$\boxed{x\in [5.55,6.45]}$

Using the formula
A = Pe^kt
Where A is the ending amount of population, P is the population k is a constant and 't' is time.

A = 0.39, t= 12 and p= 0.29
0.39= 0.29e^12k
1.34 = e^12k
ln1.34 = 12k
ln1.34/12 = k
K= 0.02

No the graph does not support his claim as k should be equal to 0.5
