Which graph represents the function
Step-by-step explanation:
Your graph will have a vertical asymptote at x = 1, as the denominator x - 1 cannot equal zero. Therefore, f(1) is not posssible. Then, plugging in test values for the function on the left side of the asymptote...
[tex]f(-1) = \frac{2(-1)-1}{-1-1} = \frac{3}{2}\\f(0) = \frac{2(0)-1}{0-1} = 1\\f(2) = \frac{2(2)-1}{2-1} = 3\\f(3) = \frac{2(3)-1}{3-1} = \frac{5}{2}[/tex]
... you will find that your graph needs to include the following points:
[tex](-1, \frac{3}{2})\\(0, 1)\\(2, 3)\\(3, \frac{5}{2})[/tex]
So therefore, your graph must cross through the above points, and may never cross the vertical line x = 1.
AB is a directed segment with endpoints A(2,2) and B(14,14). In two or more complete sentences, explain how you would verify that Point X, with a coordinate of (6,6), divides AB in a 1:2 ratio?
Answer:
Calculate the x distance from A to B and the x distance from A to X and verify that the x distance from A to X is 1/3 of the x distance from A to B.
Calculate the y distance from A to B and the y distance from A to X and verify that the y distance from A to X is 1/3 of the y distance from A to B.

5, one fifth, negative one fifth or 5, How do i solve this?
Answer:
[tex]k = \frac{4}{5} [/tex]
Step-by-step explanation:
We know from the graph
[tex]g(x) = - \frac{1}{5} [/tex]
and
[tex]f(x) = 1[/tex]
using the given equation we can solve
[tex] - \frac{1}{5} = k - 1 \\ [/tex]
subtract 1 from both sides so that k is isolated
[tex] \frac{4}{5} = k[/tex]
On his first birthday, Tomás was 30 inches tall. For the next year, he grew half an
inch each month. What equation models his height during that year, y, as a
function of the number of months, x?
Answer:
[tex]y = \frac{1}{2} x + 30[/tex]
Step-by-step explanation:
y = mx + b
y is his height during that year
x is the number of months
m is the slope or rate of change, which is 1/2 inch every month
b is the y-intercept, which is 30 inches
plug everything in then you get:
y = 1/2x + 30
Answer:
y = 1/2 x + 30

The dimensions of a cone are shown in the figure below. What is the approximate volume, in cubic centimeters, of the cone?
Answer:
B or 415
Step-by-step explanation:
the volume of a cone is given by the formula V = (pi × r^2 × h/3)
where,
V = volume of the cone,
r = the radius of the cone,
h = the height of the cone.
so by just plugging in the values we get the answer which is 415
if you need any further guidance make sure to ask. :)
The Volume of Cone is 414.48 cm³.
What is Volume?Every three-dimensional item requires some amount of space. The volume of this space is measured. Volume is defined as the space occupied by an object inside the confines of three-dimensional space. It is also known as the object's capacity.
We have,
radius = 6 cm
height = 11 cm
Now, slant height
= √r² + h²
= √11² + 6²
= √121+ 36
= √157
= 12.52 cm
Now, Volume of cone
= 1/3 πr²h
= 1/3 (3.14)(6)²(11)
= 1/3 (3.14)(36)(11)
= 414.48 cm³

What interval includes all possible values of x, where –3(6 – 2x) ≥ 4x 12? (–[infinity], –3] [–3, [infinity]) (–[infinity], 15] [15, [infinity])
The minimum of x is 15, and the most is infinity, which is the same thing as [15, ∞).
We have given inequality is
–3(6 – 2x) ≥ 4x + 12
What is the meaning of inequality?
The statement of an order relationship greater than, greater than or equal to, less than, or less than or equal to between two numbers or algebraic expressions.
[tex]-3(6 - 2x) \geq 4x + 12\\-18 + 6x \geq 4x + 12\\6x - 4x \geq 12 + 18\\2x \geq 30\\x \geq 15[/tex]
This means that the minimum of x is 15, and the most is infinity, which is the same thing as [15, ∞).

A large high school has been waging a campaign against drug use, particularly marijuana. Before the campaign began in
2007, a random sample of 100 students had their lockers checked for drugs. In 27 of the lockers, marijuana was found.
To assess if the program has been successful, another random locker check was conducted in 2017. This time, 30 out of
175 students had marijuana in their lockers. Using a = 0.05, is there evidence to suggest that the proportion of students
who are found with marijuana in their lockers has decreased?
Using the z-distribution, as we are working with a proportion, it is found that there is evidence that the proportion has decreased.
What are the hypothesis tested?At the null hypothesis, it is tested if the proportion is still the same, of 27/100 = 0.27, hence:
[tex]H_0: p = 0.27[/tex]
At the alternative hypothesis, it is tested if the proportion has decreased, hence:
[tex]H_1: p < 0.27[/tex].
What is the test statistic?The test statistic is given by:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
In which:
[tex]\overline{p}[/tex] is the sample proportion.p is the proportion tested at the null hypothesis.n is the sample size.In this problem, the parameters are as follows:
[tex]n = 175, \overline{p} = \frac{30}{175} = 0.1714[/tex]
Hence, the value of the test statistic is given by:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]z = \frac{0.1714 - 0.27}{\sqrt{\frac{0.27(0.73)}{175}}}[/tex]
z = -2.94.
What is the decision?Considering a left-tailed test, as we are testing if the propoortion is less than a value, the critical value is of [tex]z^{\ast} = -1.645[/tex].
Since the test statistic is less than the critical value for the left-tailed test, it is found that there is evidence that the proportion has decreased.
