Answers

The coordinates of the point on the unit circle corresponding to a central angle of 21 degrees are (0.93, 0.36), which is answer choice c.

The point on the unit circle corresponding to a central angle of 21 degrees can be found using the trigonometric functions sine and cosine.

In this case, the x-coordinate is equal to the cosine of the angle and the y-coordinate is equal to the sine of the angle.

Converting degrees to radians, we have:

x = cos(21) = 0.93

y = sin(21) = 0.36

None of the points listed are solutions to the equation y = 12x^3.

The equation y = 12x^3 is a polynomial equation, which describes a curve in a graph. The points listed are just random points and do not satisfy the equation. To find the solutions to the equation, we need to find the x-values that make y equal to the given value.

The equation y = 12x^3 is a cubic equation, which is a polynomial equation with degree 3. It describes a curve in a graph, where the x-values are inputs and the y-values are outputs. To find the solutions to the equation, we need to find the x-values that make y equal to the given value.

For example, if we plug in x = 1 into the equation, we get y = 12 * 1^3 = 12. This means that the point (1, 12) is a solution to the equation y = 12x^3. We can repeat this process for different x-values to find all the solutions.

consider an urn containing 12 balls, of which 7 are white and the rest are black. a sample of size 5 is to be drawn with replacement. what is the conditional probability that the first and fourth balls drawn will be white given that the sample drawn contains exactly 3 white balls?

Answers

The conditional probability that the first and fourth balls drawn will be white given that the sample drawn contains exactly 3 white balls will be  [C(5, 3) * C(2, 2) / C(12, 5)] / (C(12, 3) / C(12, 5))

The conditional probability of the first and fourth balls drawn being white given that the sample drawn contains exactly 3 white balls can be calculated as follows:

Let A be the event that the first and fourth balls drawn are white and B be the event that the sample drawn contains exactly 3 white balls. We want to find P(A|B), the probability of A given B.

Using the formula for conditional probability:

P(A|B) = P(A and B) / P(B)

To calculate P(A and B), we can use the formula for the number of combinations:

C(n, k) = n! / (k! (n - k)!)

Where n is the total number of balls, k is the number of white balls, and ! denotes the factorial symbol.

In this case, n = 5 (the sample size), k = 3 (the number of white balls), and m = 2 (the number of white balls in the first and fourth positions).

P(A and B) = C(5, 3) * C(2, 2) / C(12, 5)

P(B) = C(12, 3) / C(12, 5)

Putting it all together:

P(A|B) = P(A and B) / P(B)

= [C(5, 3) * C(2, 2) / C(12, 5)] / (C(12, 3) / C(12, 5))

First option: ∠I = ∠K

Step-by-step explanation:

The translation dilates ΔGHI about point G using a positive scale factor to generate ΔGJK.

We can use process of elimination(POE) to get rid of obviously wrong choices

∠I = ∠K is a correct choice since dilation preserves the original shape so the angles two triangles are equal and therefore the first choice appears to be the correct answer


Let's look at the other choices to make sure:

GH is smaller than GJ so GH = 2GJ is obviously false

Answers

The possible approximate lengths of b are: 2.3 units and 7.8 units

We know that the law of sines for triangle is:

The ratios of the length of all sides of a triangle to the sine of the respective opposite angles are in proportion.

This means, for triangle ABC,

[tex]\frac{sin~ A}{a} =\frac{sin~B}{b} =\frac{sin~ C}{c}[/tex]

where a is the length of side BC,

b is the length of side AC,

c is the length of side AB.

For triangle ABC consider an equation from sine law,

[tex]\frac{sin~ A}{a} =\frac{sin~ C}{c}[/tex]

here, c = 5.4, a = 3.3, and m∠A = 20°

[tex]\frac{sin~ 20}{3.3} =\frac{sin~ C}{5.4}\\\\\frac{0.3420}{3.3} =\frac{sin~ C}{5.4}[/tex]

0.3420 × 5.4 = 3.3 × sin(C)

sin(C) = 0.5596

∠C = arcsin(0.5596)

∠C = 34.03°  OR 145.9°

∠C ≈ 34° OR 146°

We know that the sum of all angles of triangle is 180 degrees.

so, ∠A + ∠B + ∠C = 180°

when m∠C = 34°,

20° + ∠B + 34.03° = 180°

∠B = 125.97°

m∠B = 126°

when m∠C = 146°,

20° + ∠B + 146° = 180°

m∠B = 14°

Now consider equation,

[tex]\frac{sin~ A}{a} =\frac{sin~ B}{b}\\\\\frac{sin~20^{\circ}}{3.3} =\frac{sin~ 126^{\circ}}{b}[/tex]

b × 0.3420 = 0.8090 × 3.3

2. Multiply the result with (x-3): x² - 2x + 1 * x - 3 = x³ - 5x² + 3x - 3

3. Simplify the equation: x³ - 5x² + 3x - 3 = 0

It is possible to solve the equation (x-1)2(x-3) = 0 by multiplying the two linear equations (x-1) and (x-3). (x-1) can be expanded as x2 - 2x + 1 since it is a square. This value will be obtained by multiplying it by (x-3): x3 - 5x2 + 3x - 3. This indicates that the two linear expressions (x-1) and (x-3) have the same product, which is equal to zero. We can make the extended form equal to zero and then solve for x to solve the equation. As a result, we will have two solutions: x = 1 and x = 3. This indicates that the equation will be true when either x = 1 or x = 3. The product of two linear expressions (x-1) and (x-3) is equal to zero, as shown by the expansion of the equation (x-1)2(x-3) = 0 to (x2 - 4x + 3) = 0.

5. A soap factory can produce 5000 units of soap in two days if five machines are used. How many units can be made in five days if 10 machines are used?

Answers

Six pipes can fill the tank in 80 minutes, therefore one pipe fills the tank in 80 minutes / 6 pipes = 13.33 minutes. Four pipes will fill the tank in 13.33 minutes * 4 pipes = 53.33 minutes.

The food is enough for 50 students for 40 days, therefore it's enough for one student for 40 days / 50 students = 0.8 days. If 30 more students join the group, the food is enough for 50 students + 30 students = 80 students, for 0.8 days / student. So, the food will last for 80 students * 0.8 days/student = 64 days.

Five trucks can transport 120 tons in 2 days, therefore one truck can transport 120 tons / 5 trucks = 24 tons in 2 days. Three trucks can transport 24 tons/truck * 3 trucks = 72 tons in 2 days. In 4 days, they will transport 72 tons * 2 days = 144 tons.

Four machines categorize 8000 packages in 8 hours, therefore one machine categorizes 8000 packages / 4 machines = 2000 packages in 8 hours. To categorize 4500 packages in 6 hours, the number of machines needed is 4500 packages / (2000 packages/machine * 8 hours/6 hours) = 4500 packages / (2000 packages/machine * 4/3) = 4500 / (2000 * 4/3) = 4500 / 2667 ≈ 1.68 machines, which is approximately 2 machines.

Five machines can produce 5000 units of soap in 2 days, therefore one machine can produce 5000 units / 5 machines = 1000 units in 2 days. Ten machines can produce 1000 units/machine * 10 machines = 10 000 units in 2 days. In five days, they will produce 10 000 units * 5 days = 50 000 units.

Answers

For every additional atmosphere of pressure applied to 1 mole of carbon dioxide at a volume of 10 L,  the volume will decrease by 9.5633 L.

The van der Waals equation is an important tool for understanding the behavior of gases. It is a mathematical equation that relates the pressure, volume, and temperature of a gas.

To find the rate of change of volume with respect to pressure, we use implicit differentiation.

This means that we take the derivative of both sides of the equation with respect to pressure (dP) while keeping all other variables constant.

After some algebraic manipulation, we find that

=> dV/dP = (V - nb)/(P + n'aV2).

This result tells us how the volume of a gas changes as the pressure changes.

To calculate the rate of change of volume with respect to pressure for 1 mole of carbon dioxide, we use the values of

V= 10 L, P=2.5atm, a=3.592 L2-atm/mole², and b=0.04267 L/mole.

Plugging in these values, we find that

=> dV/dP = (10 L - 0.04267 L)/(2.5atm + 3.592 L2-atm/mole² x 10 L2)

=> 9.5633 L/atm.

0.94^n = 3/5

Taking log on both side, we get

log(0.94^n) = log(3/5)

Using the formula log(m^n) = n logm and log(m/n) = log m - log n

n log(0.94) = log3 - log5

Now finding the value of log using calculator

n (-0.062) = 1.099 - 1.61

(-0.062)n = -0.511

Divide by (-0.062) on both side, we get

n = 8.242

The equation of the tangent line to the curve at the point (x1,y1) is

  y - y1 = - 3.54(x - x1)

What is a tangent?

The straight line that just touches the curve at a given location is referred to as the tangent line to a plane curve in geometry.

Given parametric equations,

x(t)=sin(8t)

y(t)=−8cos(−5t)

We now differentiate the above equations with respect to t.

dx/dt = 8cos(8t)

dy/dt = -8 * -5 * -sin(-5t) = -40sin(-5t)

the slope of tangent =  dy/dx of the curve.

dy/dx = (dy/dt)/(dx/dt) = -40sin(-5t) / 8cos(8t) = -5[ sin(-5t)/cos(8t) ]

Equation of a tangent to the curve

y - y1 = dy/dx (x-x1)

When t = (3π/4)

dy/dx = -5[ sin(-5*3π/4) / cos(8* 3π/4) ] = -5[ 0.707/1] = - 3.54

Therefore the equation of the tangent line at point (x1,y1) is

  y - y1 = - 3.54(x - x1)

What is graph?

A graph is a visual representation of data. It is a pictorial representation of a set of numerical values, in which individual values are plotted as points on the graph. Graphs are used to show trends, patterns and relationships between different data sets. Graphs are used in various fields including mathematics, science, economics, and statistics. Graphs can be used to represent a variety of data such as linear, nonlinear, and even categorical data. Graphs are also used to display financial data, like stock prices and currency exchange rates.

The graph would be a straight line with points (1,4), (2,6), (3,8), (4,10), and (5,12). This indicates that for 1 cart the total length is 4 feet, for 2 carts the total length is 6 feet, for 3 carts the total length is 8 feet, for 4 carts the total length is 10 feet, and for 5 carts the total length is 12 feet.

Answers

The additional information would you need to complete the boxplot are option (A), (B) and (C).

A boxplot is a visual representation of a dataset that provides information about the distribution of the data. It shows the median, quartiles, range, and any outliers in the data.

To complete the boxplot, a few additional pieces of information are required.

A. The largest value inside the fence: The high whisker on a boxplot represents the largest value that is within 1.5 times the interquartile range (IQR) of the data. To plot this, the largest value inside the fence is needed

D. The smallest value inside the fence: Similar to the high whisker, the low whisker represents the smallest value within 1.5 times the IQR of the data. To plot this, the smallest value inside the fence is needed.

C. Outliers: Outliers are values that fall outside the fences, and are plotted as individual points. To complete the boxplot, any outliers that are above the top fence and below the maximum value need to be included.

Answers

If 7 out of every 9 people had Internet access, then 2 out of every 9 people did not have Internet access. The fraction of the world population that did not have Internet access in that year would be 2/9.

A fraction represents a portion of a whole or, more broadly, any number of equal pieces; a fraction describes the number of parts of a specific size, for example, one-half.

A fraction is a portion of a larger total. The number is stated in arithmetic as a quotient, which is the numerator divided by the denominator. Both are integers in a simple fraction. A complicated fraction contains a fraction in either the numerator or the denominator. A suitable fraction has a numerator that is smaller than the denominator.

There are three primary forms of fractions in mathematics. Proper fractions, improper fractions, and mixed fractions are the three types. Fractions are phrases that have a numerator and a denominator. We describe its kinds based on these two concepts.

Answers

Costs that do not change with output are called fixed costs.

Hence the correct option is D.

Fixed costs are the costs that does not change when output gets changed. Fixed cost is also known as overhead cost. For example, insurance, rent, profit, depreciation, and normal cost.

Fixed costs are indirect costs and must be paid irrespective of the level of production, that is, these costs can be incurred even when the level of production is zero. The best example for this is rent of the factory and payment on the lease for the equipment of the factory must be paid even if the level of production is zero.
