Find the 3 smallest positive x-intercepts of the graph of
y = cos(12x) + cos(16x) and list them in increasing order.
Please give your answers as a list of x-coordinates from least to greatest.
Answers
Recall that \(\cos(x)+\cos(y)=2\cos \left(\frac{x+y}{2} \right)\cos \left(\frac{x-y}{2} \right)\).
\(\cos(12x)+\cos(16x)=0 \\ \\ 2\cos(2x)\cos(14x)=0 \\ \\ \cos(2x)\cos(14x)=0\)
If \(\cos(2x)=0\), then \(x=\frac{\pi}{4}, \frac{3\pi}{4}, \frac{5\pi}{4}, \cdots\).
If \(\cos(14x)=0\), then \(x=\frac{\pi}{28}, \frac{3\pi}{28}, \frac{5\pi}{28}, \cdots\).
So, the three smallest positive \(x\) intercepts are \(\frac{\pi}{28}, \frac{3\pi}{28}, \frac{5\pi}{28}\).

(geometry) This zigzag crystal vase has a height of 12 inches. The cross sections parallel to the base are always rectangles that are 5 inches wide by 4 inches long.
(a) If we assume the crystal itself has no thickness, what would be the volume of the base?
(b) The crystal is actually half an inch thick on each of the sides and on the bottom. Approximately how much space is contained within the vase?
Answers
Answer:
A. 9
B. 7
Step-by-step explanation:
a) The volume of the base of the crystal is 240 inches³
b) The space contained by the vase of the crystal is 24 inches³
What is the volume of a Cuboid?A cuboid is defined as a three-dimensional shape, that has six rectangular faces, eight vertices and twelve edges
The volume of a cuboid is the product of its length , width and height
The volume of the cuboid is given by
Volume of Cuboid = Length x Width x Height
Given data ,
(a) Since the cross sections are always cuboids that are 5 inches wide by 4 inches long, the area of each cross section is 5 x 4 = 20 square inches. Since the vase has a height of 12 inches, the volume of the vase is equal to the product of the area of the base and the height, which is 20 x 12 = 240 cubic inches.
(b) If the crystal is half an inch thick on each of the sides and on the bottom, then the dimensions of each cross section are 5 inches by 4 inches by 1 inch (since each side of the crystal adds half an inch to the length and width of the rectangle). The volume of each cross section is therefore 5 x 4 x 1 = 20 cubic inches.
However, since the crystal takes up half an inch on each side, the actual space contained within the vase is reduced by 2 x (5 + 4 + 0.5 + 0.5) x 12 = 216 cubic inches (where 5 + 4 is the sum of the lengths and widths of the rectangle, and 0.5 + 0.5 is the thickness of the crystal on each side).
Hence , the approximate space contained within the vase is 240 - 216 = 24 cubic inches

Answers
Answer:
The very last set
{(0, 2), (1, 4), (2, 6), (3, 6)}.
The reason why is because of the vertical line test. If there are two y-coordinates on a x-coordinate then it is not a function. A function is that each x-coordinate has a y-coordinate with the x-coordinates being different.

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

A group of seventh graders and a group of teachers at a local middle school were asked how many siblings they each have. The dot plots below show the results. Students A dot plot titled Students. A number line going from 0 to 9 labeled number of siblings. There are 2 dots above 0, 4 above 1, 7 above 2, 5 above 3, 2 above 4, and 0 above 5, 6, 7, 8, and 9. Teachers A dot plot titled Teachers. A number line going from 0 to 9 labeled Number of siblings. There is 1 dot above 0, 3 dots above 1, 2 above 2, 4 above 3, 5 above 4, 3 above 5, 1 above 6, 0 above 7, 1 above 8, and 0 above 9. When comparing the shape of the two sets of data, what conclusion can someone draw? The students tend to have fewer siblings than the teachers. The teachers tend to have fewer siblings than the students. Both the students and the teachers have a wide range of siblings. Both sets of data have the same shape. the answer is- a. The students tend to have fewer siblings than the teachers.
Answers
Answer:
A. The students tend to have fewer siblings than the teachers.
Step-by-step explanation:
First we need to draw the dot plots correctly. If you count both sides they have 20 each.
Now, clearly none have fewer nobody here yet has more or less but going on to the next step.
Multiply exactly the number of siblings times how many people chose that many siblings. Ex: 2 (siblings) times 7 (people who has 2 siblings) = 14. And so on.
On the Student A, we get a total of 41 people having sibling, if you count the 0's then there were a total of 43 people. But now on the Teacher's A Dot Plot, we have a total of 68 people, if you include the 0 then we have a total of 69.
So the answer is A. The students tend to have fewer siblings than the teachers.

The expression 2x + 4x represents the cost of buying the same number of cases of spring water, sold for $2 per case, and sparkling water, sold for $4 per case. What expression can be used to express the total cost?
Answers
Answer: 2x + 4x = (2 + 4)x = 6x
Step-by-step explanation:
The expression 2x + 4x represents the cost of buying the same number of cases of spring water and sparkling water. To express the total cost, we need to add the cost of buying the two types of water.
Since the expression 2x represents the cost of buying x cases of spring water, and 4x represents the cost of buying x cases of sparkling water, the total cost can be expressed as:
2x + 4x = (2 + 4)x = 6x
Therefore, the total cost of buying x cases of spring water and sparkling water can be expressed as 6x.
Alternatively, you can think of it as buying x cases of spring water at a cost of 2x dollars and x cases of sparkling water at a cost of 4x dollars. So the total cost is (2x+4x) dollars which is 6x dollars.

Step-by-step explanation:
We can solve for H by isolating it on one side of the equation, as follows:
J/H - I/H = G
Taking H as the common denominator:
(J - I)/H = G
Multiplying both sides by H:
J - I = GH
Adding I to both sides:
J = GH + I
Dividing both sides by G:
H = (J - I)/G
So the answer is
(A)
H = (J - I)/G.
Answer: A
Step-by-step explanation:
\(\frac{J}{H} = G + \frac{I}{H}\) >Since you are solving for H bring I/H to the other side
by subtracting I/H from both sides
\(\frac{J}{H}- \frac{I}{H} = G\) >There is a common denominator so you can
combine the fractions
\(\frac{J-I}{H} = G\) >Multiply both sides by H or cross multiply whichever
way your mind things about how to get H on top
\(J-I = G(H)\) >Divide both sides by G
\(\frac{J-I}{G} = H\) >Answer is A

*PLEASE ANSWER* Compare the volume of these two shapes,given their radii and heights are the same .
Answers
Answer:
The correct option is;
Left object volume = right object volume
Step-by-step explanation:
The shapes given in the question are two circular cones that have equal base radius and equal height
The formula for the volume, V of a circular cone = 1/3 × Base area × Height
The base area of the two shapes are for the left A = π·r², for the right A = π·r²
The heights are the same, therefore, the volume are;
For the left
\(V_{left}\) = 1/3×π·r²×h
For the right
\(V_{right}\) = 1/3×π·r²×h
Which shows that
1/3×π·r²×h = 1/3×π·r²×h and \(V_{left}\) = \(V_{right}\), therefore, the volumes are equal and the correct option is left object volume = right object volume.
