Step-by-step explanation:
Answer:
1/9
Step-by-step explanation:
When it has a bar over it, that means that the one continues. So the actual decimal is 0.11111111111. To find the answer, divide all the rational numbers. I'll do A for example. A. 1/11 (1 divided by 11) which is .09090909. It's close, but not the answer. Now, try the others.
The actual decimal is impossible to write out as it is infinite, so it is represented with a bar on top of the repeating value. \[0.03\]|

Given f (x) = x2 + 6x + 5 and g(x) = x3 + x2 − 4x − 4, find the domain of f over g of x period
{x ∈ ℝ}
{x ∈ ℝ| x ≠ −5}
{x ∈ ℝ| x ≠ −1, −2, 2}
{x ∈ ℝ| x ≠ −2, 2}
The main limiting issue with the domain this function is potentially picking an x-value that makes that denominator equal 0, because dividing by 0 is bad.
So, the domain will be all real numbers, except for those that make g(x)=0.
g(-1) = 0, g(-2)=0, and g(2) = 0, so -1, -2, and 2 must be excluded from the domain.
Your answer is {x ∈ ℝ| x ≠ −1, −2, 2}.
Answer:
[tex]\textsf{Domain}: \quad \{ x \in \mathbb{R}\;|\;x \neq -1, -2, 2\}[/tex]
Step-by-step explanation:
Given functions:
[tex]\begin{cases} f(x)=x^2+6x+5\\g(x)=x^3+x^2-4x-4\end{cases}[/tex]
Factor function f(x):
[tex]\begin{aligned}\implies f(x)&= x^2+6x+5\\&=x^2+x+5x+5\\&=x(x+1)+5(x+1)\\&=(x+5)(x+1)\end{aligned}[/tex]
Factor function g(x):
[tex]\begin{aligned}\implies g(x)&=x^3+x^2-4x-4\\&=(x+1)(x^2-4)\\&=(x+1)(x+2)(x-2)\end{aligned}[/tex]
Therefore the composite function is:
[tex]\implies \dfrac{f(x)}{g(x)}=\dfrac{(x+5)(x+1)}{(x+1)(x+2)(x-2)}[/tex]
A rational function is undefined when the denominator equals zero.
Therefore, the given composite function is undefined when (x+1)(x+2)(x-2)=0:
[tex]x+1=0 \implies x=-1[/tex][tex]x+2=0 \implies x=-2[/tex][tex]x-2=0 \implies x=2[/tex]The domain of a function is the set of all possible input values (x-values).
Therefore, as the composite function is undefined when x = -1, x = -2 and x = 2, the domain is:
[tex]\{ x \in \mathbb{R}\;|\;x \neq -1, -2, 2\}[/tex](2x - 5)

At the start of her shift at Midtown Bakery, Megan made some batches of cookies that called for 3 cups of flour each. Then, she used the remaining 8 cups of flour she had to make a pan of muffins. She started her shift with a 20-cup bag of flour.
Which equation can you use to find how many batches of cookies, x, Megan made?
How many batches of cookies did Megan make?
Meghan made 4 batches of cookies from the 20-cup bag of flour
Let x represent the number of batches of cookies Megan made. Since each batch is made from 3 cups of flour and the remaining 8 cups of flour she had to make a pan of muffins.
Since she had initially 20-cup bag of flour, hence:
3x + 8 = 20
3x = 12
x = 4
Hence Meghan made 4 batches of cookies from the 20-cup bag of flour.

and art teacher had 2/3 gallons of paint to pour into containers. if he poured 1/8 gallon of paint into each container until he ran out of paint, how many containers had paint in them including the one that was partially filled.
Step-by-step explanation:
we divide 2/3 by 1/8 (to see how often 1/8 fits into 2/3).
remember, when dividing one fraction by another, it is the same as multiplying with the upside-down second fraction.
2/3 / 1/8 = 2/3 × 8/1 = (2×8)/(3×1) = 16/3 = 5 1/3
that means that there are 5 containers with 1/8 gallon of paint, and a 6th container with a little bit of paint left (a third of 1/8 gallons = 1/8 / 3/1 = 1/8 × 1/3 = 1/24), 1/24 of a gallon.
so, 6 containers in total have paint in them.

Explain why solving a system of equations using graphing is not a useful solution technique?
Answer:
solving a system of equations using graphing is not a useful solution technique because you are plotting on a 2D surface. For example, if you graph the system below, you get the following graph. ... While you can approximate the solution to this system, you cannot say exactly where the intersection point is since it does not fall on integer values on the number lines.

The graph of y=f(x) is shown below. find all the values of x where f(x)=6
Answer:
x = -4, 4
Step-by-step explanation:
When it says find all the values of x where f(x) = 6, it is basically asking for the x values where y would equal 6. So if you look at the graph, y equals 6 when x = -4 and x = 4.

The perimeter of a square is 48 inches. What is the area, in square inches, of the square?
Statement:The perimeter of a square is 48 inches.
Solution:We know, perimeter of a square = 4 × length of a side of a square.So, the length of a side of a square = Perimeter of the square ÷ 4Therefore, the length of the given square= 48 inches ÷ 4
= 12 inches
Now, area of a square = square of the length of a side of the squareTherefore, the area of the given square= (12 inches)^2
= (12×12) square inches
= 132 square inches
Answer:The area of the square is 132 square inches.

Recently, a nurse commented that when a patient calls the medical advice line claiming to have the flu, the chance that he or she truly has the flu (and not just a nasty cold) is only about 4%. Of the next 25 patients calling in claiming to have the flu, we are interested in how many actually have the flu.
Find the probability that at least four of the 25 patients actually have the flu.
The probability that at least four of the 25 patients actually have the flu is 0.013
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
The probability P(X ≥ 4).
By De Morgan's Law, this is equal to 1-P(X<4).
If we add up the values of x=0,1,2,3 from our pmf,
[tex]$p_x = \binom{25}{x}(0.04)^x(1-0.04)^{25-x}$[/tex]
So, x=4
P(4) = 25! / 4! ( 25- 4)! x [tex]0.04^4[/tex] [tex](1 - 0.04)^{25- 4}[/tex]
P(4) = 0.013
Hence, the probability that at least four of the 25 patients actually have the flu is 0.013
