The required correct option out of given is B) This scale factor results in an enlarged image is correct.

Finding the dilation's center point is the first step in determining the scale factor. Next, we measure the distances between the center point and various points on the preimage and the image. According to Math Bits Notebook, the scale factor is equal to the ratio of these lengths.

When the scale factor of a dilation is greater than 1, the image is an enlargement.

In this case, the scale factor is 8:7, which means that every length in the image is 8/7 times larger than the corresponding length in the original figure. Therefore, the image is larger than the original figure.

So; B) This scale factor results in an enlarged image is correct.

The gravitational pull of the Sun on the object would decrease as the distance between them increased.

If the velocity of an orbiting body were increased, its orbital path would change from an elliptical orbit to a parabolic or hyperbolic orbit, depending on the extent of the increase in velocity.

The amount of gravitational pull on the object would decrease as the distance between the object and the Sun increased. This is because gravitational force decreases with distance according to the inverse-square law.

In summary, if the velocity of an orbiting body were increased to the point where its orbital path changed into a parabolic or hyperbolic orbit, the object would eventually escape the Sun's gravitational pull and move away from it in a straight line.

The number of $0.49$ stamps Paula bought is s = (1274 - 49s / 21) + 6.

To solve the equation 0.49s + 0.21(s - 6) = 12.74 for s, we can multiply both sides by 100 to get:

49s + 21(s - 6) = 1274

Now, we can move the 21(s - 6) term to the left side of the equation and the 49s term to the right side of the equation. To do this, we will subtract the 49s from both sides of the equation, which yields:

21(s - 6) = 1274 - 49s

Next, we can divide both sides of the equation by 21 to isolate the (s - 6) term, resulting in:

(s - 6) = 1274 - 49s / 21

Finally, we can add 6 to both sides of the equation to solve for the number of $0.49$ stamps that Paula bought:

s = (1274 - 49s / 21) + 6

Therefore, the number of $0.49$ stamps Paula bought is s = (1274 - 49s / 21) + 6.

c) The equation of the tangent line is 12x - 7.

a) To find the derivative of f(x), we can use the power rule for each term. The power rule states that for any function f(x) = xⁿ, the derivative f'(x) = nx^(n-1). So for f(x) = 4x³ + 1, Thus, the derivative f'(x) = 12x².

b) To compute the derivative of f at x=1, we simply plug in x=1 into the derivative equation we found in part a. So f'(1) = 12(1)² = 12.

c) To determine the equation of the tangent line to the curve y=f(x) at the point (1,5), we use the point-slope form of a line, which is y-y1 = m(x-x1), where m is the slope of the line and (x1,y1) is the point the line passes through. The slope of the tangent line is the derivative of f at x=1, which we found in part b to be 12. So the equation of the tangent line is y-5 = 12(x-1), or y = 12x - 7.

The constant proportionality between the x-coordinates and y-coordinates of these four points is 12.

What is Proportionality?

Proportionality refers to the relationship between two quantities that change in a consistent and predictable way. In a proportional relationship, when one quantity changes, the other quantity changes in a constant ratio or proportion to the first.

Assuming that you want to find the constant proportionality between the x-coordinates and y-coordinates of these four points:

First, we can calculate the ratios of the y-coordinates to the x-coordinates for each point:

For (3,36): y/x = 36/3 = 12

For (5,60): y/x = 60/5 = 12

For (6,72): y/x = 72/6 = 12

For (7,84): y/x = 84/7 = 12

We can see that the ratios are all equal to 12. Therefore, the constant proportionality between the x-coordinates and y-coordinates of these four points is 12.

Note that if you had asked for the constant proportionality between the differences in the y-coordinates and the differences in the x-coordinates of these points, the answer would be different. That constant proportionality is known as the slope of the line passing through these points.

the values of a that satisfy the inequality |a|≤5 are those that satisfy both a ≤ 5 and a ≥ -5. This is why the expression equivalent to |a|≤5 is a ≥ –5 and a ≤ 5.

In mathematics, an expression is a combination of numbers, variables, and operators that can be evaluated to produce a value. It can be as simple as a single number or variable, or as complex as a long sequence of operations involving multiple variables and operators.

The expression |a|≤5 means that the absolute value of a is less than or equal to 5. The absolute value of a number is its distance from zero on the number line, regardless of whether the number is positive or negative.

So, if |a|≤5, then a must be between -5 and 5, including both.

To see why this is true, consider two cases:

If a is greater than or equal to zero, then |a| = a, and so we have a ≤ 5.

If a is less than zero, then |a| = -a, and so we have -a ≤ 5, which is equivalent to a ≥ -5.

The solutions for θ in the interval [0, 2π) where cos(θ) = -√3/2 are θ = 2π/3 and θ = 4π/3.

The graph of f(θ) is shifted and stretched when compared to the graph of f(2θ).

What is Trigonometry?

Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles, and the trigonometric functions that describe those relationships.

Part A:

To find when the pogo stick's spring will be equal to its non-compressed length, we need to solve for when f(θ) = 0.

f(θ) = 2cos(θ) + √3 = 0

2cos(θ) = -√3

cos(θ) = -√3/2

The solutions for θ in the interval [0, 2π) where cos(θ) = -√3/2 are θ = 2π/3 and θ = 4π/3.

Part B:

If we double the angle, θ becomes 2θ, and the function becomes:

f(2θ) = 2cos(2θ) + √3

Using the double angle formula for cosine, we can rewrite this as:

f(2θ) = 2(2cos²(θ) - 1) + √3

f(2θ) = 4cos²(θ) - 2 + √3

Substituting cos(θ) = -√3/2, we get:

f(2θ) = 4(-3/4) - 2 + √3

f(2θ) = -3 + √3

So the solutions for 2θ in the interval [0, 2π) where f(2θ) = 0 are:

2θ = π/6 and 2θ = 11π/6

Dividing by 2, we get the solutions for θ:

θ = π/12 and θ = 11π/12

These solutions are different from the solutions in Part A, and the graph of f(θ) is shifted and stretched when compared to the graph of f(2θ).

Part C:

To find when the lengths of the springs are equal, we need to solve the equation f(θ) = g(θ).

2cos(θ) + √3 = 1 - sin²(θ) + √3

2cos(θ) = 1 - sin²(θ)

Using the identity sin²(θ) + cos²(θ) = 1, we can rewrite this as:

2cos(θ) = cos²(θ)

cos(θ)(cos(θ) - 2) = 0

The solutions for θ in the interval [0, 2π) where the lengths of the springs are equal are:

θ = 0, θ = π/3, θ = 2π/3, θ = π, θ = 4π/3, θ = 5π/3

We can check that f(θ) = g(θ) at each of these values.

To solve the system of linear inequalities, we need to graph each inequality and find the region that satisfies both inequalities.

Here are the steps:
1. Graph the first inequality: -2x-y1. We can rearrange the equation to get y>-2x-1. This means that the region above the line y=-2x-1 is the solution to the first inequality.
2. Graph the second inequality: 3x+y<6. We can rearrange the equation to get y<-3x+6. This means that the region below the line y=-3x+6 is the solution to the second inequality.
3. The solution to the system of inequalities is the region that satisfies both inequalities. This is the region above the line y=-2x-1 and below the line y=-3x+6.
4. To find the coordinates of the vertices of the solution region, we can find the intersection point of the two lines. Setting the two equations equal to each other, we get: -2x-1=-3x+6. Solving for x, we get x=7. Substituting x=7 into one of the equations, we get y=-3(7)+6=-15. So the intersection point is (7,-15).
5. The solution region is the triangular region with vertices at (7,-15), (0,-1), and (2,0).

There are a total of 28 different 3-digit numbers that can be formed from the numbers 1,3,5,7,9 if each number formed is greater than 300. This can be found by using the formula for distinguishable permutations.

There are a total of 5 different 3-digit numbers that can be formed from the numbers 1,3,5,7,9 if each number formed is greater than 300. These numbers are 315, 357, 375, 397, and 359. This can be found by using the formula for distinguishable permutations, which is n!/(n-r)!, where n is the total number of items and r is the number of items chosen. In this case, n is 5 (the numbers 1,3,5,7,9) and r is 3 (the number of digits in each number formed).

The formula for distinguishable permutations is:

n!/(n-r)!

Answer:

To create a perfect-square binomial of the form (y - k)^2, we need to find the value of k such that:

the first term of the binomial is y^2 (which is already the case)

the second term of the binomial is -2ky (which corresponds to -36y in the given expression)

the third term of the binomial is k^2 (which corresponds to 81 in the given expression)

To find k, we can use the formula:

k = (1/2)*(-b/a)

where a is the coefficient of y^2, b is the coefficient of y, and we are looking for the value of k that makes the expression a perfect square.

In this case, a = 1 and b = -36, so:

k = (1/2)(-b/a) = (1/2)(-(-36)/1) = 18

Therefore, the missing number to create a perfect-square binomial is 18:

1). How many seats are there in each section? So the stadium is divided into 12 sections and 8 are VIP boxes so 12 - 8 = 4 so there are 4 non-VIP sections. Now to find out how many seats are in each section we need to divide the number of seats by the number of sections which would be 10,500 ÷ 12 = 875.

2). If all the seats in the premium section are sold out for the game how many will the stadium get from those ticket sales? So first we need to find out how many seats there are in the premium section, we already know that there are 4 premium sections and we also know that there are 875 seats in each section. Multiply the number of sections by the number of seats 4 x 875 = 3,500 now multiply the number of seats by the cost of the seat 3,500 x $48 = $168,000

Volume = (1/3) * area of base * height

Substituting:

Volume = (1/3) * (15 m * 12 m) * 20 m = 1200 m³

b) The volume of the oblique cone is:

Volume = (1/3) * π * radius² * height

but radius = 30 ft / 2 = 15 ft,

Substituting:

Volume = (1/3) * π * 15² * 25  = 5890 ft³

The volume of the cone is 5890 ft³

c) The volume of the triangular prism is:

Volume = area of base * height

Substituting:

Volume = (1/2 * 9 ft * 5 ft) * 14.3 ft = 321.75 ft³

In the given figure the equation m∠MRS + m∠MRO = 180° is the postulate describing the linear pair of angles.

The English word "angle" derives from the Latin word "angulus," which means "corner." The vertex and the two rays are referred to as the sides of an angle, respectively, and are the shared termini of two rays.

It is given that -

∠MRS ≅ ∠MRO

Now, what that means is that ∠MRS is congruent to ∠MRO.

Thus, to understand this concept of equality or congruence, we can prove it since from the given image, we see that -

m∠MRS = m∠MRO = 90°

Since they are both right angles then we can say that the correct theorem is the definition of a right angle triangle.

m∠MRS + m∠MRO = 180°

It is seen that the angles form a linear pair and lie on the same plane.

Therefore, the correct postulate is linear pair.

The prοbability οf the events is:

P(A and B) = 7/100

P(A | B) = 16/25

P(A | B) = 0.495

P(A and B) = 0.175

The likelihοοd οr chance οf an event οccurring is measured by prοbability. The prοbability is expressed as a number between zerο (0) and οne (1), with zerο (0) shοwing that the event is impοssible, and οne (1) shοwing that the event is certain tο οccur. A prοbability οf 0.5 indicates that the event is equally likely tο οccur οr nοt οccur.

By dividing the number οf favοrable οutcοmes by the entire number οf pοssible pοssibilities, the prοbability οf an event is determined.

Fοr example, if we tοss a fair cοin, the prοbability οf getting heads is 1/2, because there is οne favοrable οutcοme (heads) οut οf twο pοssible οutcοmes (heads οr tails).

Therefοre, All events are dependent, sο the prοbability οf each event is:

P(A and B) = 7/100

P(A | B) = 16/25

P(A | B) = 0.495

P(A and B) = 0.175
