Answer:
Right-angled Triangle
Explanation:
Since one the angles of the triangle is 90 degrees then the triangle will be a right-angle triangle because it has a one right angle in it.
A focus group of 12 people is to be chosen randomly from among 24 right-handed people and 5 left-handed people. In order to find the probability that 3 of the people chosen are right-handed, you should use
Let 1 and 2 mean that a person is right-handed or left-handed, respectively.
Consider the probability space as the different groups of 12 people that can be formed with the 29 total people. {(1,1,1,1,1,...1),(2,1,1,1,1,...,1),...}
We need to use the binomial distribution in order to find the answer.
Consider X to be the number of right-handed people in the group.
The probability of X=3 is then:
\(Pr(X=3)=\text{ binomial coefficien(}12,3\text{)}(\frac{24}{29})^3(1-\frac{24}{29})^{12-3}\)We used the formula
\(\begin{gathered} Pr(X=k)=\text{ binomial coefficient(n,k)}\cdot p^k(1-p)^{n-k} \\ \text{where } \\ k=3 \\ n=12 \\ p=\frac{24}{29} \end{gathered}\)Finally, we need to simplify the expression, as shown below
\(\Rightarrow P(X=3)=220(\frac{24}{29})^3(\frac{5}{29})^9=0.0000167\)This is the answer one obtains using the binomial distribution; nevertheless, the actual probability is equal to zero because it is not possible to form a group of 12 people that only contains 3 right-handed people as there are only 5 left-handed people (3+5=8).

f(x)= (x^2 + x - 12)/(x^2 + 6x + 9)

b. f(x) --> ∞ as x --> 4^+ and as x --> 4^-

d. f(x) --> -∞ as x --> 3^+ and as x --> 3^-, f(x) --> ∞ as x --> -4^+ and as x --> -4^-
e. f(x) --> -∞ as x --> -3^+ and as x --> -3^-
Answer:
e. f(x) --> -∞ as x --> -3^+ and as x --> -3^-
Step-by-step explanation:
You want to know the behavior of f(x)= (x^2 + x - 12)/(x^2 + 6x + 9) near any excluded x-values.
DomainThe function can be factored as ...
\(f(x)=\dfrac{x^2+x-12}{x^2+6x+9}=\dfrac{(x+4)(x-3)}{(x+3)^2}\)
The excluded values are values of x where the denominator is zero. The only excluded value is x = -3. (eliminates all answer choices except E)
Asymptotic behaviorAt either side of x = -3, the sign of the numerator is negative and the sign of the denominator is positive. That makes f(3-) < 0 and f(3+) < 0.
f(x) will never approach +∞, but f(x) approaches -∞ as x nears -3 from either direction.
Answer:
\(\textsf{e)} \quad f(x) \rightarrow -\infty\;\;\textsf{as}\;\; x \rightarrow -3^+ \;\;\textsf{and as}\;\;x \rightarrow -3^-\)
Step-by-step explanation:
Given function:
\(f(x)=\dfrac{x^2+x-12}{x^2+6x+9}\)
Factor the numerator:
\(\implies x^2+x-12\)
\(\implies x^2+4x-3x-12\)
\(\implies x(x+4)-3(x+4)\)
\(\implies (x-3)(x+4)\)
Factor the denominator:
\(\implies x^2+6x+9\)
\(\implies x^2+3x+3x+9\)
\(\implies x(x+3)+3(x+3)\)
\(\implies (x+3)(x+3)\)
\(\implies (x+3)^2\)
Therefore, the rational function is:
\(f(x)=\dfrac{(x-3)(x+4)}{(x+3)^2}\)
As the degree of the numerator is equal to the degree of the denominator, there is a horizontal asymptote at y = 1.
A vertical asymptote occurs at the x-value(s) that make the denominator of a rational function zero.
\(\implies (x+3)^2=0\)
\(\implies x+3=0\)
\(\implies x=-3\)
Therefore, there is a vertical asymptote at x = -3.
As there is a vertical asymptote at x = -3, the excluded x-value is x = -3.
As x approaches x = -3 from both sides, the numerator of the rational function approaches -6 and the denominator approaches a very small positive number. Therefore, the function approaches a very large negative number.
Therefore, the end behaviour of the function as it approaches the excluded value is:
\(f(x) \rightarrow -\infty\;\;\textsf{as}\;\; x \rightarrow -3^+ \;\;\textsf{and as}\;\;x \rightarrow -3^-\)Nikhil and Mae work at the same company. Nikhil has been at the company 4 time+s as long as Mae. Nikhil's time at the company is 8 more than 2 times Mae's time. The following system of equations models the scenario: x = 4y x = 8 + 2y How many years has each person been employed by the company? Nikhil has been with the company for 16 years, while Mae has been there for 4 years. Nikhil has been with the company for 24 years, while Mae has been there for 6 years. Nikhil has been with the company for 20 years, while Mae has been there for 5 years. Nikhil has been with the company for 12 years, while Mae has been there for 3 years
Applying the system of equations given, we can conclude that: a. Nikhil has been with the company for 16 years, while Mae has been there for 4 years.
How to Apply a System of Equations?To solve the system of equations, let's substitute the value of x from the first equation into the second equation:
x = 4y
8 + 2y = 4y
Simplifying the equation, we get:
8 = 2y
Dividing both sides by 2:
4 = y
Now, substitute the value of y back into the first equation to find x:
x = 4y
x = 4(4)
x = 16
Therefore, Nikhil has been employed by the company for 16 years, and Mae has been employed for 4 years.
The correct answer is option a. Nikhil has been with the company for 16 years, while Mae has been there for 4 years.

[3x (4.6÷2)] +14.1 =
Answer:

Step-by-step explanation:
PEMDAS : Parenthesis, Exponent, Multiplication/Division, Addition/Subtraction.
First, we want to deal with the parenthesis within the parenthesis.
(4.6/2) = 2.3
Rewrite it into the equation.
[3 * 2.3] + 14.1 = ?
Now, do the work in the parenthesis again.
[6.9] + 14.1 = ?
There isn't anymore parenthesis, exponents, or multiplication/division, so we move onto addition now and add both terms.
6.9 + 14.1 = 21

Fundamental theorem of calculus
\(g(s)=\int\limits^s_6 {(t-t^4)^6} \, dt\)
Answer:
\(\displaystyle g'(s) = (s-s^4)^6\)
Step-by-step explanation:
The Fundamental Theorem of Calculus states that:
\(\displaystyle \frac{d}{dx}\left[ \int_a^x f(t)\, dt \right] = f(x)\)
Where a is some constant.
We can let:
\(\displaystyle g(t) = (t-t^4)^6\)
By substitution:
\(\displaystyle g(s) = \int_6^s g(t)\, dt\)
Taking the derivative of both sides results in:
\(\displaystyle g'(s) = \frac{d}{ds}\left[ \int_6^s g(t)\, dt\right]\)
Hence, by the Fundamental Theorem:
\(\displaystyle \begin{aligned} g'(s) & = g(s) \\ \\ & = (s-s^4)^6\end{aligned}\)
Use the graph to find the indicated function value. y = f(x). Find f(4)
Looking at the graph, we can see that there is a point on the graph that lies on the vertical line x = 4 and has a corresponding y-value of 3. This point is the point (4, 3). So, the value of f(4) is 3.
What is function?In mathematics, a function is a relation between two sets of objects in which each element of the first set (called the domain) is associated with exactly one element of the second set (called the range).
To find f(4) from the given graph, we need to locate the point on the graph that corresponds to x = 4 and read off the corresponding value of y.
The graph shows that there is a point (4, 3) on the graph of the function y = f(x). This means that when x = 4, the value of y (or f(x)) is 3. Therefore, f(4) = 3.
In general, to evaluate a function at a given point, we need to substitute that point's value for the independent variable (in this case, x) in the function expression and simplify the resulting expression.
However, in this case, we are given the value of x and simply need to read off the value of y from the graph.

Find the length of the line joining A (3,5) and B (1,3)
Answer:
2√2 units.
Step-by-step explanation:
To find the length of the line joining points A(3, 5) and B(1, 3), we can use the distance formula. The distance formula is given by:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
Substituting the coordinates of points A and B into the formula, we have:
d = sqrt((1 - 3)^2 + (3 - 5)^2)
= sqrt((-2)^2 + (-2)^2)
= sqrt(4 + 4)
= sqrt(8)
= 2sqrt(2)
Therefore, the length of the line joining points A and B is 2√2 units.

y - 4 = ²/₃x + 2
y = ²/₃x + 6
17) We are given the equation of a line as;
-2x + 7y = 14
7y = 2x + 14

Suppose the radius of a cylinder changes, but its volume stays the same. How must the height of the cylinder change?
1. If the radius increases then height must increase
2. If radius decreases then height must decrease
3. The height doesn’t change
4. If the radius increases, height decreases
If the radius increases, height decreases, Therefore option no 4 is correct
If the radius of a cylinder changes, however its volume remains the same, then the height of the cylinder have to change.
Mainly, if the radius increases, then the height must decrease & if the radius decreases then the height must to increase. this is because the volume of a cylinder is given by means of the formulation:
\(V = \pi r^2h\)
In which V is the volume, r is the radius &h is the height. If we keep the volume constant, and increase the radius, then we ought to lower the height in order to make amends for the increased extent.
Similarly, if we decrease the radius, then we must increase the height to catch up on the reduced volume.
Therefore, the appropriate answer is:
If the radius increases, height decreases
