Answer:

the ratio used was 1:19

Step-by-step explanation:

let a be the action figure version

let r be the real iron man

let's list out the important things.

a = 4''

r = 6'4''

one foot has 12 inches

convert r into inches:

6 × 12 = 72           (6 feet in r)

       r = 76''          (72 + 4)

r = 76''

a = 4''

ratio is 4:76

simplify

4:76

2:38

1:19

the ratio they used is 1:19

Answer:

x = \(\frac{9}{80}\)

Step-by-step explanation:

Given

x + \(\frac{9}{20}\) = \(\frac{9}{16}\)

Multiply through by 80 ( the LCM of 20 and 16 ) to clear the fractions

80x + 36 = 45 ( subtract 36 from both sides )

80x = 9 ( divide both sides by 80 )

x = \(\frac{9}{80}\)

Step-by-step explanation:(a) To find two other pairs of polar coordinates of (3, π/4):

One with r > 0: (3, 9π/4)

One with r < 0: (-3, 5π/4)

To plot the point (3, π/4), we start at the origin and move 3 units along the line that makes an angle of π/4 radians with the positive x-axis.

(b) To find two other pairs of polar coordinates of (2, -2π/3):

One with r > 0: (2, 4π/3)

One with r < 0: (-2, π/3)

To plot the point (2, -2π/3), we start at the origin and move 2 units along the line that makes an angle of -2π/3 radians (which is the same as 4π/3 radians) with the positive x-axis.

(c) To find two other pairs of polar coordinates of (-2, π/6):

One with r > 0: (2, 7π/6)

One with r < 0: (-2, 19π/6)

To plot the point (-2, π/6), we start at the origin and move 2 units in the direction that makes an angle of π/6 radians with the positive x-axis, but since r is negative, we move in the opposite direction. So we end up at a point on the line that makes an angle of 7π/6 radians with the positive x-axis.

In a National Drug Code, the third set of digits, which consists of two numbers, represents the product strength and dosage form of the drug.

The National Drug Code (NDC) is a unique identifier assigned to drugs in the United States. It is a three-segment code that includes the labeler code, the product code, and the package code. Each segment provides specific information about the drug.

The third set of digits in the NDC represents the product strength and dosage form of the drug. These two numbers indicate the concentration or potency of the active ingredient in the drug and the specific form in which it is formulated, such as tablets, capsules, liquid, or injections.

For example, if the third set of digits is "10-20", it might indicate that the drug has a strength of 10 milligrams per dosage unit and is in the form of tablets. The specific interpretation of the digits may vary depending on the drug and the standards set by regulatory authorities.

Therefore, option (a) is the correct answer: The third set of digits in a National Drug Code represents the product strength and dosage form of the drug.

The general solution to the differential equation. If initial conditions are given, we can solve for the constants C1 and C2.

The given differential equation is:

y ln x * (dx/dy) = [(y+1)/x]^2

We can solve this equation by separation of variables, which means we can rearrange the equation so that all the x terms are on one side and all the y terms are on the other side. Then, we can integrate both sides with respect to their respective variables.

First, we rewrite the equation in a form suitable for separation of variables:

y ln x dx = [(y+1)/x]^2 dy

Next, we separate the variables and integrate both sides:

∫y ln x dx = ∫[(y+1)/x]^2 dy

Integrating the left-hand side by parts, we have:

u = ln x dv = y dx

du/dx = 1/x v = (1/2) y^2

∫y ln x dx = (1/2) y^2 ln x - ∫(1/2) y dx

= (1/2) y^2 ln x - (1/4) y^2 + C1

where C1 is the constant of integration.

Integrating the right-hand side, we use the substitution u = y+1:

u = y+1 du = dy

∫[(y+1)/x]^2 dy = ∫(u/x)^2 du

= (1/x^2) ∫u^2 du

= (1/3x^2) u^3 + C2

where C2 is the constant of integration.

Substituting this back into the original equation, we have:

(1/2) y^2 ln x - (1/4) y^2 + C1 = (1/3x^2) (y+1)^3 + C2

This is the general solution to the differential equation. If initial conditions are given, we can solve for the constants C1 and C2.

the answer is 1/10 :))))))))

The expression that represents the sum of the areas of the triangles shown is 15 + 24 + 14 = 53 square units.

To find the sum of the areas of the triangles shown, we need to calculate the area of each triangle and then add them together. Since all of the triangles are right triangles, we can use the formula:

Area of triangle = 1/2(base x height)

Triangle ABC: Base = 5 units

Height = 6 units

Area = 1/2(5 x 6) = 15 square units

Triangle DEF:Base = 8 units

Height = 6 units

Area = 1/2(8 x 6) = 24 square units

Triangle GHI:Base = 7 units

Height = 4 units

Area = 1/2(7 x 4) = 14 square units

Therefore, the sum of the areas of the triangles shown is:15 + 24 + 14 = 53 square units

Step-by-step explanation:

The range of the random variable is from 0 to 17,000.

The range of the random variable is the set of all possible values that the variable can take on. In this case, the variable is the number of people who carry the gene ifi202. Since 17,000 people are being tested, the range of the variable is from 0 to 17,000.

This is because it is possible that none of the people tested carry the gene, or that all 17,000 people tested carry the gene. Any number of people between 0 and 17,000 could also carry the gene, so the range of the variable is 0 to 17,000.

a) the dimension of its column space is also 2. b) the rank of A is 2. c) the nullity of matrix A is 1. d) the dimension of the solution space of the homogeneous system \(A_x = 0\) is also 1.

(a) The dimension of the row space of a matrix is equal to the dimension of its column space. So, if the dimension of the row space of matrix A is 2, then the dimension of its column space is also 2.

(b) The rank of a matrix is defined as the maximum number of linearly independent rows or columns in the matrix. Since the dimension of the row space of matrix A is 2, the rank of A is also 2.

(c) The nullity of a matrix is defined as the dimension of the null space, which is the set of all solutions to the homogeneous equation Ax = 0. In this case, the matrix A is a 3 x 3 matrix, so the nullity can be calculated using the formula:

nullity = number of columns - rank

nullity = 3 - 2 = 1

Therefore, the nullity of matrix A is 1.

(d) The dimension of the solution space of the homogeneous system Ax = 0 is equal to the nullity of the matrix A. In this case, we have already determined that the nullity of matrix A is 1. Therefore, the dimension of the solution space of the homogeneous system \(A_x = 0\) is also 1.

Answer:  The graph is shown below. It is nonlinear

==========================================================

Explanation:

I used GeoGebra to make the graph. Desmos is another option I recommend.

The equation we graph is y = (1/2)^x since we're splitting the paper in half each time. This is an exponential decay function. Note how the curve slopes downhill when moving to the right.

It appears the curve touches or crosses the x axis; which is misleading. Instead, the curve is getting closer and closer to this horizontal asymptote. It will never reach the x axis. Think of it like an electric fence.

As the graph indicates, we don't have a straight line. Therefore, the function isn't linear. It's a nonlinear curve.

a)the ratio of the heights of the pyramids is 5:3. b)the volume of the larger pyramid is 23.04 cm³.

what is volume  ?

Volume is a measure of the amount of space that a three-dimensional object occupies. It is usually measured in cubic units, such as cubic meters (m³) or cubic centimeters (cm³). The volume of an object can be calculated using different formulas depending on its shape.

In the given question,

a. Let the height of the smaller pyramid be h₁ and the height of the larger pyramid be h₂. Since the two pyramids are similar, their corresponding linear dimensions are in the same ratio as the areas of their bases. Therefore, we have:

(base area of smaller pyramid)/(base area of larger pyramid) = (linear dimension of smaller pyramid)² / (linear dimension of larger pyramid)²

Since the linear dimension is the height in this case, we can substitute the given ratio of the base areas to obtain:

25/9 = (h₁/h₂)²

Taking the square root of both sides, we get:

h₁/h₂ = 5/3

Therefore, the ratio of the heights of the pyramids is 5:3.

b. Since the volume of a pyramid is proportional to the cube of its height, we have:

(volume of smaller pyramid) / (volume of larger pyramid) = (h₁/h₂)³ = (5/3)³ = 125/27

Substituting the given volume of the smaller pyramid, we get:

108 / (volume of larger pyramid) = 125/27

Solving for the volume of the larger pyramid, we obtain:

volume of larger pyramid = (27/125) * 108 = 23.04 cm³ (rounded to two decimal places)

Therefore, the volume of the larger pyramid is 23.04 cm³.

The expected value of a random variable represents the average value we would expect to obtain if we were to repeat the experiment many times. For a discrete random variable, such as the one you described, the expected value is given by the formula:

E(X) = Σ[x * P(x)],

where x is the possible values that the random variable can take, and P(x) is the probability of the random variable taking the value x.

In your case, the random variable X represents the number of occurrences of an event over an interval of ten minutes, and it is known that the mean number of occurrences in ten minutes is 5.3. Therefore, we can assume that the probability of an occurrence is λ/10, where λ is the average rate of occurrences per minute.

To find the expected value of X, we can use the formula:

E(X) = Σ[x * P(x)]

Since the number of occurrences can range from 0 to infinity, we need to consider all possible values of X. We can use the Poisson distribution to calculate the probability of each value of X, where the parameter λ is equal to 0.53, which is the average number of occurrences per minute.

Using the Poisson distribution formula, the probability of X taking the value x is given by:

\(P(X = x) = (e^(-λ) * λ^x) / x!\)

Substituting λ = 0.53, we have:

P(X = 0) = (e^(-0.53) * 0.53^0) / 0! = 0.5878

P(X = 1) = (e^(-0.53) * 0.53^1) / 1! = 0.3113

P(X = 2) = (e^(-0.53) * 0.53^2) / 2! = 0.0827

P(X = 3) = (e^(-0.53) * 0.53^3) / 3! = 0.0139

and so on...

We can then use the formula for expected value to find the expected value of X:

E(X) = Σ[x * P(x)] = (0 * 0.5878) + (1 * 0.3113) + (2 * 0.0827) + (3 * 0.0139) + ...

Evaluating this infinite sum (which can be done using a calculator or statistical software), we find that the expected value of X is approximately 5.59 occurrences per 10 minutes.
