(would really, reallly appreciate the brainliest)
Step-by-step explanation:
plotted with desmos (free online math tool)
The function whose graph is given is y = 0.5cosx
What is a function?A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given that, a graph we need to find its function,
To analyze the given graph let us,
compare the given to a known, standard functiontake maxima and minima points from the graph and analyze them.From the given graph we can pick the points which can tell us about the nature of the cosine function we took,
It is clear from the graph that the function plotted is equal to the standard function i.e. cos(x)
in cos(x) ⇒ we have minima at (-π, 1)
in the given graph, the function has a maximum and touches the y-axis at (0, 0.5)
Therefore, 0.5cosx is the function represented in the graph.

What is the completely factored form of f(x) = x^3 – 2x^2 – 5x + 6?
Answer:
D
Step-by-step explanation:
Answer:d
Step-by-step explanation:
A jeweler sells gems at a cost in dollars per centigram that is 4 more than 6 times the weight of the gem in centigrams.
Thus, a gem that weighs w centigrams will be sold at a price of 6w + 4 dollars per centigram - meaning that a larger,
heavier gem will cost more per centigram than a smaller gem. If the jeweler sold a single gem for about $2500, what
did the gem weigh to the nearest centigram?
Answer:
416 centigrams
Step-by-step explanation:
2500 = 6w + 4
2496 = 6w
416 = w
Jarods bicycle wheel has a diameter of 27 inches. How far will the wheel have traveled in one full rotation? Use 3.14 for pi
Answer:
84.78 in
Step-by-step explanation:
in order to figure out how long it will travel you will need to find the circumference in order to do that you have to do [tex]2 *\pi * radius[/tex] so that is [tex]2*3.14*13.5[/tex] which equals 84.78
Mr. Sanders teaches a painting class. He makes the histogram below to summarize the
number of paintings each student has completed since the class began. Mr. Sanders says
that the histogram shows that of the students have finished 12 or more paintings.
Number of Paintings
Finished by Students
Number of Students
N
0-2 3-5 6-8 9-11 12-14 15-17
Number of Finished Paintings
What error did Mr. Sanders likely make, and what is the actual fraction of students who have
completed 12 or more paintings? Use the drop-down menus to explain his reasoning and correct
his mistake.
Mr. Sanders likely found that of the students have completed 12 or more paintings because
there are Choose... bars on the histogram, and choose... of the bars represent
students with 12 or more completed paintings. The actual fraction of the students who have
completed 12 or more paintings is Choose...
Answer:
Answer: (1st box) = 6 (2nd box) = 2 (3rd box) = 2/3
Step-by-step explanation:
I got this question too and I got it right. ❤️
Mr. Sanders most certainly discovered that one-third of pupils have done 12 or more paintings because the histogram has six bars, two of which reflect students who have completed 12 or more paintings. The actual percentage of pupils who have completed 12 or more paintings is [tex]\frac{4}{19}[/tex].
Mr. Sanders' class has 19 students. That histogram has six bars. He most likely assumed it because [tex]\frac{2}{6} = \frac{1}{3}, \frac{1}{3}[/tex] of his pupils finished 12 or more paintings. That is not the case. 2 different isn't even a whole number. The other dates are[tex] \frac{2}{3}, \frac{4}{19}, \ and \ \frac{4}{17}[/tex]. Two-thirds and 4 are not whole figures either. That leaves [tex]\frac{4}{19}[/tex]. Four-nineteenths equal a complete number four. Since there are no such things as partial pupils, we must enter [tex]\frac{4}{19}[/tex].Therefore, the answer is "[tex]\to (1^{st}\ box) = 6 (2^{nd}\ box) = 2 (3^{rd}\ box) = \frac{2}{3}[/tex]"

The area of a circle is given by A = πr^2 , where π = 3.14 and r is the radius of the circle. Determine the area of a circle with radius 14.2 cm. Round your answer to the nearest tenth.
Answer:
The area of the circle is 1988.1 cm.
Step-by-step explanation:
You basically have all of the instructions on how to do this in the question.
Multiply 3.14 by the radius. 3.14 x 14.2 = 44.588Now you just have to square it. 44.588^2 = 1988.0897.And lastly we have to just round it to the nearest tenth. Rounded = 1988.1.I hope I helped.

Hey there! I'm happy to help you!
The formula for the volume of a sphere is [tex]V=\frac{4}{3} \pi r^{3}[/tex], which is the the radius cubed multiplied by pi and 4/3. There are a lot of interesting proof videos out there about how this formula is derived and it is super cool and you would love it!
If our radius is 8 centimeters, we can plug it in like this:

7. The distance between point (–4, 5) and another point is 10. What are the possible
coordinates of the other point?
A (2, 2)
B (2, 3)
C (2, –3)
D (–2, –3)
Answer:
D (-2, -3)
Step-by-step explanation: The distance is 10 units, so you take -4 (x) and go over 2 spaces so your at x = -2, and 2 units are down, 8 more to go. Then for (y) you do 5-8 and get -3 so now y = -3 . Now you have moved 10 spaces because 2 + 8 = 10 spaces, and are left at D (-2, -3).

line. When you click Done, your line will
appear.
Answer:
Step-by-step explanation:
Answer: Second point is (0.833,0)
Step-by-step explanation:
1. To determine slope you must use this formula Y= Mx + B
- M is the slope (positive or negative)
- B is the y-intercept
2. To find y-intercept you use (0, B)
3. M = -6/1
- 6 units down and 1 unit to the right since the slope is negative.

Solve the following inequality in two ways and make a claim as to which
method is more efficient.
1/4 (8n - 12) < n + 2
Answer:
The solution of the given inequality n < 5
Step-by-step explanation:
Explanation:-
Given inequality
[tex]\frac{1}{4} (8 n -12 ) < n +2[/tex]
Step(i):-
Cross multiplication '4' we get
8 n - 12 < 4 ( n +2)
8 n - 12 < 4 n + 4×2
8 n - 12 < 4 n +8
Subtracting '4 n ' on both sides, we get
8 n - 4 n - 12 < 4 n - 4 n +8
4 n - 12 < 8
Step(ii):-
Adding ' 12 ' on both sides , we get
4 n -12 + 12 < 8 + 12
4 n < 20
Dividing "4' on both sides , we get
n < 5
The solution is n < 5
Conclusion:-
The solution of the given inequality n < 5

Answer: 1/2:1/3
I hope this helps
Step-by-step explanation:
In the problem it says 1/2 of the students in the school like math, and it also says in the problem that 1/3 of the students in the school like science. The question is asking for a ratio of students who like math to students who like science, so now the only thing you need to do is input those 2 numbers in the order that they want it in. Which is 1/2:1/3. And don't forget that the colon : is what you always put in between the two numbers.

Is (3, 2) a solution of -8x – 2y < 6?
Answer:
yes
Step-by-step explanation:
To determine if the point is a solution, substitute the coordinates into the left side of the inequality, evaluate and compare with right side.
- 8(3) - 2(2) = - 24 - 4 = - 28 < 6
Thus (3, 2) is a solution
Answer:
Yes.
Step-by-step explanation:
Let's substitute x = 3 and y = 2 into the inequality:
-8(3) - 2(2) = -28 which is less than 6 so it is a solution.
