A polynomial function has x-intercepts at -2, 1/2, and 2 and a relative maximum at x = -1.
Which graph matches the description of this function?
Answers
Answer: A :)
Step-by-step explanation:
The function goes through -2, 1/2, and 2, maximum goes through x= -1
By using the information about the x-intercepts and the relative maximum, we can see that the correct option is A.
How to find the correct graph of the polynomial?
First, we know that we have a relative maximum at x = -1, this means that we have a "mountain" at x = -1.
The only two graphs with that feature are A and B.
Now we also know that the x-intercepts are:
-2, 1/2, and 2.
Where the x-intercepts are the values of x at which the graph intercepts the x-axis. There you can see that we have one negative and two positives, from that, we can conclude that the only correct option can be A (because B has two negatives and one positive x-intercepts).
Finally, we conclude that the correct option is A.

Let the parts be 2x, 3x and 5x.
Sum= 25000
Therefore,2x+3x+5x=25000
10x=25000
x=25000/10
x=2500
Therefore, parts:-
1. 2×2500=5000
2. 3×2500=7500
3. 5×2500=12500
Answer:
5000, 7500, 12500
Step-by-step explanation:
[tex]2 + 3 + 5 = 10[/tex]
[tex]25000[/tex] ÷ [tex]10[/tex] = [tex]2500[/tex]
[tex]2500[/tex] × [tex]2 = 5000[/tex]
[tex]2500[/tex] × [tex]3 = 7500[/tex]
[tex]2500[/tex] × [tex]5 = 12500[/tex]
[tex]\therefore[/tex] [tex]25000[/tex] will split into [tex]5000[/tex], [tex]7500[/tex], and [tex]12500[/tex].
To check if the answer is correct, you can add the values up and see if they sum up to [tex]25000[/tex]:
[tex]5000 + 7500 + 12500 = 25000[/tex]

Step-by-step explanation:
△ABC ≅ △DEF means that these two triangles are congruent to each other. Congruent triangles also have corresponding sides and angles that are equal to each other!
This means that angle A corresponds to angle D; and thus, we can set up in equation for these two to solve for y.
First, let's try to decipher what exactly we are solving. Y is what we are multiplying by five to get 60°, or angle A (congruent angle).

This is finding exact values of sin theta/2 and tan theta/2. I’m really confused and now don’t have a clue on how to do this, please help
Answers
First,
tan(θ) = sin(θ) / cos(θ)
and given that 90° < θ < 180°, meaning θ lies in the second quadrant, we know that cos(θ) < 0. (We also then know the sign of sin(θ), but that won't be important.)
Dividing each part of the inequality by 2 tells us that 45° < θ/2 < 90°, so the half-angle falls in the first quadrant, which means both cos(θ/2) > 0 and sin(θ/2) > 0.
Now recall the half-angle identities,
cos²(θ/2) = (1 + cos(θ)) / 2
sin²(θ/2) = (1 - cos(θ)) / 2
and taking the positive square roots, we have
cos(θ/2) = √[(1 + cos(θ)) / 2]
sin(θ/2) = √[(1 - cos(θ)) / 2]
Then
tan(θ/2) = sin(θ/2) / cos(θ/2) = √[(1 - cos(θ)) / (1 + cos(θ))]
Notice how we don't need sin(θ) ?
Now, recall the Pythagorean identity:
cos²(θ) + sin²(θ) = 1
Dividing both sides by cos²(θ) gives
1 + tan²(θ) = 1/cos²(θ)
We know cos(θ) is negative, so solve for cos²(θ) and take the negative square root.
cos²(θ) = 1/(1 + tan²(θ))
cos(θ) = - 1/√[1 + tan²(θ)]
Plug in tan(θ) = - 12/5 and solve for cos(θ) :
cos(θ) = - 1/√[1 + (-12/5)²] = - 5/13
Finally, solve for sin(θ/2) and tan(θ/2) :
sin(θ/2) = √[(1 - (- 5/13)) / 2] = 3/√(13)
tan(θ/2) = √[(1 - (- 5/13)) / (1 + (- 5/13))] = 3/2

Answers
Answer:
I hope this helps you
Step-by-step explanation:
The magnitude of given operations of vectors are found.
What are Vectors?Vectors are quantities which are having the independent properties of magnitude as well as direction.
Given that,
u = (-3, 8) and v = (-14, 6)
3u = (-9, 24) and 2v = (-28, 12)3u - 2v = (-9+28, 24-12) = (19, 12)
Magnitude of 3u - 2v = [tex]\sqrt{19^2+12^2}[/tex] = [tex]\sqrt{505}[/tex] units
2u = (-6, 16) and 3v = (-42, 18)2u - 3v = (36, -2)
Magnitude = [tex]\sqrt{36^2+(-2)^2}[/tex] = [tex]\sqrt{1300}[/tex] units
u = (-3, 8) and 4v = (-56, 24)u + 4v = (-59, 32)
Magnitude = [tex]\sqrt{(-59)^2+32^2}[/tex] = [tex]\sqrt{4505}[/tex] units
5u = (-15, 40) and v = (-14, 6)5u - v = (-1, 34)
Magnitude = [tex]\sqrt{1157}[/tex] units
7u = (-21, 56) and 2v = (-28, 12)7u - 2v = (7, 44)
Magnitude = [tex]\sqrt{1985}[/tex] units.
Hence the magnitude of vectors are found.

Determining the Range:
We know that the range of a relation is the set of all the y-values of the set Y. In other words, the range of relation includes all the output values.Therefore, the range: {-6, 0, 6}
Therefore, we conclude that option (a) is correct.

Total number of students who roller skated = 80
Number of students who roller skated with laser tag = 39
Number of students who roller skated with no laser tag = 80 - 39 = 41
Therefore, percentage of students who roller skated with no laser tag = [tex]\frac{41}{154}\times 100[/tex] = 27%
Since, number of students who played laser tag = 85
Percentage of students who played laser tag = [tex]\frac{85}{154}\times 100[/tex] = 55%
Total number of students who played no laser tag = 45% of 154 = 69
Number of students with no roller skates and no laser tag = 69 - 41 = 28
Percentage of students with no roller skates and no laser tag = [tex]\frac{28}{154}\times 100[/tex]
= 18%
Percentage of students who played with no rollers skates = (30 + 18)%
= 48%
