Two blocks are initially at rest with a compressed spring between them. When the spring is released, the 2m block moves to the left and the m block moves to the right. This represents an inelastic collision in a closed system.
A diagram of two square masses sitting on a flat horizontal surface connected by a spring. The mass on the left is labeled 2 m and the mass on the right is labeled m.
What best describes the blocks after the spring is released?
The total energy is zero.
The total momentum is zero.
The momentum of the m block is zero.
The momentum of the 2m block is zero.
The statement that best describes the blocks after the spring is released is the total momentum is zero.
Law of conservation of momentumFrom the law of conservation of momentum, the initial momentum of the system, M equals the final momentum of the system M'
M = M'
Momentum of blocks
Now, since both blocks are initially at rest, the initial momentum M = 0.
Since the initial momentum equals the final momentum after the blocks are released,
M = M' = 0
So, the total momentum after the blocks are released is zero.
So, the statement that best describes the blocks after the spring is released is the total momentum is zero.

-3x^2+33=48x complete the square
The complete square form of - 3x² + 33 = 48x is [x + 8]² = 75
Completing the square:
To do this, we add and subtract a constant term to the quadratic expression to make it a perfect square.
In this case, we use the formula x² + 2bx + b² = (x + b)² to rewrite the quadratic expression as a perfect square trinomial, and then we solved for the variable by isolating the squared term and taking the square root.
Here we have
- 3x² + 33 = 48x
Keep 'x' terms on one side and constant terms sides on another side
=> - 3x² - 48x = - 33
Divide by - 3 on both sides
=> -3(x² + 4x)/3 = - 33/3
=> x² + 16x = 11
Take half of the 'x' term and square it and add on both sides
=> x² + 2(8x) (x) + (8)² = 11 + (8)²
Which is in the form of x² + 2bx + b² = (x + b)²
=> [x + 8]² = 75
Therefore,

The surface area of the vase is 168.4 square inches.
What is a cylinder?
A cylinder is a three-dimensional geometric shape that has two congruent circular bases connected by a curved surface.
The surface area of the cylindrical vase can be found using the formula SA = B + Ph, where B is the area of the base, P is the perimeter of the base, and h is the height of the vase. Since the vase has a circular base, the area of the base can be found using the formula for the area of a circle: B = πr², where r is the radius of the base.
The diameter of the vase is 4.3 inches, so the radius is half of that, or 2.15 inches. The area of the base is therefore:
B = πr² = 3.14 * (2.15)² ≈ 14.46 square inches.
The perimeter of the base is the circumference of the circle, which can be found using the formula C = 2πr:
P = 2πr = 2 * 3.14 * 2.15 ≈ 13.53 inches.
Now we can use the formula SA = B + Ph to find the surface area of the vase:
SA = B + Ph = 14.46 + 13.53 * 11 ≈ 168.39 square inches.
Rounding to the nearest tenth of a square inch, the surface area of the vase is approximately 168.4 square inches.

Liam cuts a 48-inch piece of string into two pieces. One piece is 12 inches longer than the other. If s represents the length of the shorter string, which diagram best represents this scenario?
The length of the shorter string is 18 inch while that of the longer string is 30 inch.
An equation is an expression used to show the relationship between two or more variables and numbers.
Let s represent the length of the shorter string.
One piece is 12 inches longer than the other
Length of longer string = s + 12
Since a 48-inch piece of string is cut into two pieces. Hence:
s + (s + 12) = 48
2s + 12 = 48
2s = 36
s = 18
Length of longer string = 18 + 12 = 30
The length of the shorter string is 18 inch while that of the longer string is 30 inch.

5. When we simplify (1 + sin x)(1 - sin x), the result obtained is cos² x
6. When we simplify cos x + sin xtan x, the result obtained is sec x
How do i simplify the trig identities?We can simplify the trig identities as follow:
1. Simplification of sec² x + tan² xsec² x
sec² x + tan² xsec² x = sec² x(1 + tan² x)
Recall
sec² x = 1 + tan² x
Thus,
sec² x(1 + tan² x) = sec² x × sec² x
sec² x(1 + tan² x) = sec⁴x
Therefore, the simplified is written as
sec² x + tan² xsec² x = sec⁴x
2. Simplification of (sec² x - 1) / sin² x
(sec² x - 1) / sin² x
Recall,
sec² x - 1 = tan² x
Thus,
(sec² x - 1) / sin² x = tan² x / sin² x
Recall
tan² x = sin² x / cos² x
Thus,
tan² x / sin² x = (sin² x / cos² x) / sin² x
tan² x / sin² x = 1/ cos² x
Recall
1/ cos² x = sec² x
Therefore, the simplified expression is written as:
(sec² x - 1) / sin² x = sec² x
3. Simplification of (1/sec² x) + (1/csc² x)
(1/sec² x) + (1/csc² x)
Recall
sec² x = 1/cos² x
Thus,
cos² x = 1/sec² x
Also,
csc² x = 1/sin² x
Thus,
sin² x = 1/csc² x
Therefore, we have
(1/sec² x) + (1/csc² x) = cos² x + sin² x
Recall
cos² x + sin² x = 1
Thus, the simplified expression of (1/sec² x) + (1/csc² x) is:
(1/sec² x) + (1/csc² x) = 1
4. Simplification of (sec x / sin x) - (sin x / cos x)
(sec x / sin x) - (sin x / cos x) = (sec xcos x - sinx sinx) / sinx cos x
Recall
sec x = 1/cos x
sinx sinx = sin² x
Thus,
(sec x / sin x) - (sin x / cos x) = [(cos x/cos x) - sin² x] / sinx cos x
(sec x / sin x) - (sin x / cos x) = [1 - sin² x] / sinx cos x
Recall
1 - sin² x = cos² x
Thus, we have
[1 - sin² x] / sinx cos x = [cos² x] / sinx cos x
[1 - sin² x] / sinx cos x = cos x / sin x
Recall
cos x / sin x = cot x
Thus, the simplified expression of (sec x / sin x) - (sin x / cos x) is:
(sec x / sin x) - (sin x / cos x) = cot x
5. Simplification of (1 + sin x)(1 - sin x)
(1 + sin x)(1 - sin x)
Clear bracket
1 - sin x + sin x - sin² x
1 - sin² x
Recall
1 - sin² x = cos² x
Thus, we have
(1 + sin x)(1 - sin x) = cos² x
6. Simplification of cos x + sin xtan x
cos x + sin xtan x
Recall
tan x = sin x / cos x
cos x + sin xtan x = cos x + sin x (sin x / cos x)
cos x + sin xtan x = cos x + (sin² x / cos x)
cos x + sin xtan x = (cos² x + sin² x) / cos x
Recall
cos² x + sin² x = 1
cos x + sin xtan x = 1 / cos x
1/cos x = sec x
Thus,
cos x + sin xtan x = sec x
The simplified expression of cos x + sin xtan x is sec x

Brandon went to the store and spent $2.50 on pencils. He spent half of what he had left on a notebook and paper. When he got home he had $5.00 left. How much money did Brandon have before going to the store?
Answer: The best problem solving strategy to solve this problem with is a formula. Additionally Brandon had $12.50 before going to the store.
Step-by-step explanation: Formula and Solving it
He Spent $2.50 on pencils.
Amount left after buying a pencil = x - 2.50
Next, he spent half of the amount left in his pocket.
He spent (x - 2.50)/2 on notebook and paper.
So the total amount he spent = 2.50 + (x -2.50)/2
Amount left when he got home =$ 5.00
That means, x - Total amount spent = 5
=> x - (2.50 + (x -2.50)/2 ) = 5
=> x - 2.50 -x/2 + 2.50/2 = 5
=> x/2 - 2.50/2 = 5
=> x/2 = 5 + 2.50/2
=> x/2 = 6.25
=>x = $12.5

Parallel lines have the same slopes. Therefore,
\(m_{k} =m_{p}\)
The slope of line k (\(m_{k}\)) will be equal to the slope of the line parallel to k (\(m_{p}\)).
We know that the slope of line k is 2/3.
\(m_{k}=\frac{2}{3}\)
Therefore, the slope of the line parallel to line k is also 2/3.
\(\frac{2}{3}=m_{p}\)
The slope of a line parallel to line k is 2/3.

A vacant lot is being converted into a community garden. The garden and a walkway around its perimeter have an area of 648 square feet. Find the width of the walkway if the garden measures 12 feet wide by 15 feet long.
The width cannot be negative, the width of the walkway is 6 feet. The total area of the garden and the walkway is given as 648 square feet. We know the area of the garden is length multiplied by width, which in this case is 12 feet by 15 feet, so the garden area is\(12 \times 15 = 180\) square feet.
To find the area of the walkway, we subtract the garden area from the total area. Therefore, the area of the walkway is 648 - 180 = 468 square feet.
The walkway surrounds the garden on all sides, so its length and width will be greater than the corresponding dimensions of the garden.
To calculate the width of the walkway, we can use the formula for the area of a rectangle, which is length multiplied by width. In this case, the length is 12 + 2x (twice the width of the walkway) and the width is 15 + 2x.
So, we have the equation\((12 + 2x) \times (15 + 2x) = 468\).
Expanding and rearranging the equation, we get\(4x^2 + 54x - 228 = 0.\)
Solving this quadratic equation using factoring, completing the square, or the quadratic formula, we find that x = 6 or x = -9/2.

The correct option, C. The function is positive when x > 0, for the graph of cube root parent function.
Define the term cube root parent function?The opposite of such cubic function is the cube root function.
We are aware that its parent cubic function is ascending, one-one, and onto, and that its form is f(x) = x³. It results in a bijection as a result. As a result, its cube root inverse function, of the type f(x) = ∛x, also forms a bijection.The definition of the cube root for all numbers may be found in the introduction, as we have already seen (positive, real, and 0). As a result, there is no x for which any cube root function, f(x), is not defined. Therefore, the set among all real numbers is its domain (R).Similar to the square root function, the range of a cube root function is the set among all real numbers because it produces all values (positive, real, and 0). Consequently, a cube root function is f(x): R → R.Thus, using the domain and range we can see from the graph that, for the positive values of the function, the graph is increasing for positive values.
Therefore, The function is positive when x > 0.
