What is formula for work done?1/T = 1/T1 + 1/T2 + 1/T3 +... + 1/Tn, where T is the time it takes for all n persons to complete the task and T1, T2,..., Tn are the times it takes for each person to do the task individually, is the formula for addressing issues involving work done by several people. This equation is based on the premise that each person's contribution to the activity is inversely proportionate to the time it takes them to do it. In other words, a person contributes more effort to the entire task the faster they work. This method may be used to determine how long it will take all n persons working together to do the assignment in total.
The work done is calculated by:
1/T = 1/T1 + 1/T2 + 1/T3
Here, we have T1 = 20, T2 = 26 and T3 = 32 hours for work done separately.
Substituting the values:
1/T = 1/20 + 1/26 + 1/32
1/T = (32/640) + (24/640) + (20/640)
1/T = 76/640
T = 640/76
T ≈ 8.4 hours
Therefore, it would take them about 8.4 hours to add the special effects if they all work together.

The required volume of the given sphere is 904.32 cm³.
What is a sphere?A sphere is a geometrical object that resembles a two-dimensional circle in three dimensions.
In three-dimensional space, a sphere is a collection of points that are all located at the same distance from a single point.
The radius of the sphere is denoted by the letter r, and the specified point represents its center.
All of the points on a circle are equally spaced apart from the center along a plane, but all of the points on a sphere are equally spaced apart from the center along any of the axes.
So, we must ascertain the sphere's volume. With a radius of 6 cm, we have:
V = 4/3 π r^3
V = 4/3 x 3.14 x 6^3
V = 4/3 x 3.14 x 216
V = 904.32
Therefore, the required volume of the given sphere is 904.32 cm³.

What is the equation of the line that passes through the point (-4, 2) and has a
slope of -1?
Answer:
Step-by-step explanation:
The equation of a line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept.
We are given that the line passes through the point (-4, 2) and has a slope of -1. This means that we can substitute the values of the point and slope into the equation and solve for b.
y = mx + b
2 = (-1)(-4) + b
2 = 4 + b
b = -2
Now we know the slope and y-intercept of the line, so we can write the equation in slope-intercept form:
y = -x - 2
Therefore, the equation of the line that passes through the point (-4, 2) and has a slope of -1 is y = -x - 2.
what is the probability of rolling a three
Answer:
1/6
Step-by-step explanation:
I am assuming you mean the probability of rolling a 3 on a die.
If you are rolling only 1 die, with the numbers 1 through 6, then the chance of landing on any number is 1/6.
For example, the chance of landing on a 2 or 5 are equal, both 1/6.
Therefore, the chance of landing on a die is 1/6.

ABCD is a cyclic quadrilateral with AB=5. 6 BC=4. 5,CD=3. 4,AD=2. 5 calculate ABC to the nearest 0. 1°and AC correct to 1dp
A) To the nearest 0.1°, [tex]$\angle ABC\approx63.8\textdegree$[/tex] and B) AC is approximately 4.2 units long, correct to 1 decimal place.
A) We can use the law of cosines to solve for the angles of triangle ABC and then use the fact that opposite angles in a cyclic quadrilateral are supplementary to find angle ADC. Finally, we can use the law of cosines again to find AC.
Let angle ABC be x. Then, applying the law of cosines to triangle ABC, we have:
[tex]$AC^2=AB^2+BC^2-(2AB* BC*\cos(x))$[/tex]
Substituting the given values, we get:
[tex]$AC^2=5^2+4.5^2-2\cdot5\cdot4.5\cdot\cos(x)$[/tex]
Simplifying and solving for AC, we get:
[tex]$AC=\sqrt{3.125+11.25\cos(x)-10\cos^2(x)}$[/tex]
Next, applying the law of cosines to triangle BCD, we have:
[tex]$\cos(ADC)=\frac{3.4^2+4.5^2-(2*3.4*4.5*\cos(x))}{3.4*4.5}$[/tex]
Simplifying, we get:
[tex]$\cos(ADC)=\frac{29.15-15.3\cos(x)}{15.3}$[/tex]
Since ABCD is a cyclic quadrilateral, we have:
[tex]$\angle ADC=180\textdegree-\angle ABC=180\textdegree-x$[/tex]
Substituting this into the above equation and solving for [tex]$\cos(x)$[/tex], we get:
[tex]$\cos(x)=\frac{7.2}{15.3}$[/tex]
Using a calculator, we find that
[tex]$x\approx63.8\textdegree$[/tex].
Therefore, [tex]$\angle ADC\approx116.2\textdegree$[/tex].
B) Finally, substituting [tex]$x\approx63.8\textdegree$[/tex] into the expression for AC, we get:
[tex]$AC=\sqrt{3.125+11.25\cos(63.8\textdegree)-10\cos^2(63.8\textdegree)}$[/tex]

A jogger is running at 8m/s and their mass is 64kg. What is their momentum?
The jogger's momentum is 512 kg·m/s.
The momentum of an object is defined as the product of its mass and velocity.
Mathematically, momentum (p) can be expressed as:
p = m x v
where m is the mass of the object and v is its velocity.
Momentum is an important concept in physics because it describes the quantity of motion an object possesses. The momentum of an object can be changed by applying a force to it for a certain period of time. This change in momentum is called impulse and is equal to the force multiplied by the time it acts on the object.
In this case, the jogger's mass is given as 64 kg and their velocity is given as 8 m/s. To find their momentum, we can simply multiply these values:
p = m x v
p = 64 kg x 8 m/s
p = 512 kg*m/s
Therefore, the momentum of the jogger is 512 kg*m/s.

The normal distribution is a probability curve that describes a data set that follows a symmetrical pattern. In this case, the normal distribution applies because the reading level of the students in the elementary school is normally distributed.
The mean for the reading level is 85 words per minute and the standard deviation is 22 words per minute.
The child's reading level of 44.2 words per minute falls at the 16th percentile. This means that 16% of the students have a lower reading level than the child, and 84% have a higher reading level.
The normal distribution graph (attached below) illustrates this concept, with the mean of 85 words per minute and the student's reading level marked at the 16th percentile.
The percentile of the student's reading level emphasizes the gravity of the situation. The graph demonstrates that the student is below average in reading level and is in need of remediation.
A suggested course of action is to provide the student with extra help in reading, such as one-on-one tutoring or extra reading material. Additionally, the student should be encouraged to practice and hone their reading skills in order to reach their reading potential.

In this warm-up activity, you will use your knowledge from the previous lesson on compound angle formulas to derive expressions for the double angle formulas.
Derive a general expression for sin(2θ) and cos(2θ). Hint: sin(2θ) = sin(θ + θ), and use the compound angle formula that was introduced in the previous lesson. Be sure to do this for both sin(2θ) and cos (2θ).
The general expressions for sin(2θ) and cos(2θ) are Sin(2θ) = 2sinθcosθ, and cos(2θ) = cos2θ − sin2θ.
The formula for deriving sin(2θ) and cos(2θ) is as follows:
To derive the sin(2θ) formula, use the following formula: sin (2θ) = 2sinθcosθ
And to derive the cos(2θ) formula, use the following formula: cos(2θ) = cos2θ − sin2θ
From the compound angle formulas, we know that:
Sin (α + β) = sinαcosβ + cosαsinβ, and Cos (α + β) = cosαcosβ − sinαsinβ
We may derive sin(2θ) from the above formulas by putting α = β = θ, which gives us:
Sin (2θ) = sinθcosθ + sinθcosθSin (2θ) = 2sinθcosθcos(2θ) can be derived from the above formula by following these steps:
Cos (2θ) = cosθcosθ − sinθsinθCos (2θ) = cos2θ − sin2θ

1. Señora Cruz asks her student Molly to determine the formula for finding the area of the parallelogram and the rectangle. Moly says the formugs are the same. Is she correct? Why or why not?
Molly is correct in stating that the formula for finding the area of a parallelogram and a rectangle is the same.
What is parallelogram?A parallelogram is a four-sided polygon with two pairs of parallel sides. The opposite sides of a parallelogram are equal in length and parallel to each other. The opposite angles of a parallelogram are also equal in measure. The area of a parallelogram can be found by multiplying the base of the parallelogram by its height, where the height is the perpendicular distance between the parallel sides. Some common examples of parallelograms include rectangles, squares, and rhombuses. Parallelograms are used in various areas of mathematics, physics, and engineering, and are commonly encountered in geometry problems and applications.
What is a rectangle?A rectangle is a four-sided polygon with two pairs of parallel sides and four right angles. The opposite sides of a rectangle are equal in length, and the adjacent sides are perpendicular to each other
According to the given informationBoth a parallelogram and a rectangle are types of quadrilaterals (four-sided polygons). The formula for finding the area of any quadrilateral is to multiply the base of the shape by its height. In the case of a parallelogram, the base and height are not necessarily the same as the sides of the shape are not perpendicular to each other. However, in the case of a rectangle, the base and height are the same as the sides are perpendicular to each other.
Therefore, the formula for finding the area of a parallelogram is:
Area = base x height
And the formula for finding the area of a rectangle is also:
Area = base x height
Since the formulas are the same, Molly is correct in stating that the formula for finding the area of a parallelogram and a rectangle is the same.

what is sequence ?A sequence in mathematics is a group of numbers that are organized in a particular order and that adhere to a particular pattern or formula. Sequences can be endless or finite and have a variety of uses in many disciplines, including probability theory, analysis, and number theory. Sequences can be defined recursively, where each term is defined in terms of the terms that came before it, or they can be defined using a formula that produces each term of the sequence. For instance, using the equation a = 2n, where n is a positive integer and a1 = 2 is the first term, one can determine the sequence of even numbers. If n is greater than 1, it can also be defined recursively as a1 = 2, and a = an-1 Plus 2.

Describe Equation?Equations can be written in many forms, but they all have the same basic structure: an expression on the left-hand side of the equals sign, and an expression on the right-hand side of the equals sign, with the equals sign itself indicating that the two expressions are equal.
Let the number of true/false questions be x and the number of multiple choice questions be y. We know that:
x + y = 20 (since there are 20 questions in total)
3x + 11y = 100 (since the test is worth 100 points)
We can solve this system of equations by substitution or elimination. Here, we'll use substitution:
x + y = 20 -> x = 20 - y
Substitute x = 20 - y into the second equation:
3x + 11y = 100
3(20 - y) + 11y = 100
60 - 3y + 11y = 100

[tex](x) + (x+6) + (2x+14) = 180\\4x + 20 = 180\\4x = 160\\x = 40[/tex]
The value of x° = 40°.
Would you help me with this question. I'm not sure what this answer is.
The area of the figure is 18 mm².
What is area?The area is the amοunt οf space within the perimeter οf a 2D shape. It is measured in square units, such as cm², m², etc.
Yοu can think οf area as the area inside a given shape οr space. It refers tο hοw much space is taken up. The larger the shape, the larger the area and perimeter οf the shape will be. Nοt tο be cοnfused with vοlume, area οnly refers tο space taken up by a flat οr 2D οbject.
We have given the figure, with all right angles,
Draw an imaginary rectangle of 5 × 6, that covers up the whole figure.
Now,
The area of full rectangle - area of small rectangle = area of the figure
⇒ (6 × 5) - (4 × 3)
⇒ 30 - 12
⇒ 18 mm²
Thus, the area of the figure is 18 mm².

Find the
coordinates of the points on the graph of
ƒ(x) = ½ x³ − ¹⁄2x² − 8x + 7 where the gradient is 4.
Answer:
(-8/3, 19/27) and (3, -17/2).
Step-by-step explanation:
To find the coordinates of the points on the graph of ƒ(x) = ½x³ − ¹⁄₂x² − 8x + 7 where the gradient is 4, we need to find the points where the derivative of ƒ(x) is equal to 4.
First, we need to find the derivative of ƒ(x):
ƒ'(x) = 3/2x² - x - 8
Next, we need to set ƒ'(x) = 4 and solve for x:
3/2x² - x - 8 = 4
3/2x² - x - 12 = 0
Multiplying both sides by 2 to eliminate the fraction:
3x² - 2x - 24 = 0
Factoring the quadratic equation:
(3x + 8)(x - 3) = 0
So x = -8/3 or x = 3.
Now we can find the corresponding y-coordinates:
When x = -8/3:
ƒ(-8/3) = 1/2(-8/3)³ - 1/2(-8/3)² - 8(-8/3) + 7 = 19/27
So one point on the graph with gradient 4 is (-8/3, 19/27).
When x = 3:
ƒ(3) = 1/2(3)³ - 1/2(3)² - 8(3) + 7 = -17/2
So another point on the graph with gradient 4 is (3, -17/2).
Therefore, the coordinates of the points on the graph of ƒ(x) = ½x³ − ¹⁄₂x² − 8x + 7 where the gradient is 4 are (-8/3, 19/27) and (3, -17/2).

Which z-values correspond to the bottom 48% of the standard normal distribution?
Answer:
-0.11
Step-by-step explanation:
Using a standard normal distribution table or calculator, we can find that the closest z-value to 0.48 in the table is -0.11.
This means that approximately 48% of the area under the standard normal distribution is to the left of -0.11.
