If the velocity of an orbiting body were increased, its orbital path would change
into a parabola or hyperbola. If this were to happen, what would happen to the
object and its gravitational pull of the Sun?
The gravitational pull of the Sun on the object would decrease as the distance between them increased.
What is the gravitational pull?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.

Find the missing number to create a perfect-square binomial
___ y2-36y+81
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:
(y - 18)^2 = y^2 - 36y + 324
Write the correct postulate, theorem, property, or definition that justifies the statement below the diagram.
Given: ∠MRS ≅ ∠MRO
In the given figure the equation m∠MRS + m∠MRO = 180° is the postulate describing the linear pair of angles.
What is an angle?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.

So the fourth force FA that would need to be added to make the net force zero is < 6, 9 >.
The net force on an object is the sum of all the forces acting on it. In this case, there are three different forces acting on the object: F1, F2, and F3. Each of these forces has a magnitude of < -2, -3 >. To find the net force Fnet, we simply add up all the forces:

Fnet = < -2, -3 > + < -2, -3 > + < -2, -3 >
Fnet = < -6, -9 >
To find the fourth force FA that would need to be added to make the net force zero, we simply need to find a force that is equal and opposite to Fnet. That is:

t = 164.5 minutes.
How to obtain the time needed?The number of bacteria after t minutes is given by the exponential function presented as follows:
P(t) = 1000e^(0.042t).
The population will reach 1,000,000 when:
P(t) = 1,000,000.
Hence the time needed is obtained solving the equation as follows:

a) The derivative f'(x) is 12x².
b) The amount of f'(1) is 12.
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.

This graph shows a proportional relationship.
What is the constant of proportionality?
Enter your answer in the box.
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 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.

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.
What is expression ?
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.
Therefore, 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.

Solve the following system of linear inequalities: \[ \begin{array}{l} -2 x-y1 \end{array} \]
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).
Therefore, the solution to the system of linear inequalities is the region with vertices at (7,-15), (0,-1), and (2,0).

2 A DVD rental company charges $10 per month plus $0.75 per rental. Andy wants to spend no more than $25.00 per month on DVD rentals.
Select the inequality that represents how many DVDs Andy can rent in one month that satisfies this condition. The number of rentals in a month is represented by n.
The inequality that represents how many DVDs Andy can rent in one month that satisfies this condition is 10 + .75n ≤ 25
The correct answer choice is option B
Which inequality represents how many DVDs Andy can rent in one month?Cost of rental per month = $10
Additional cost = $0.75
Number of DVD's rented = n
Total amount Andy want to spend ≤ $25
The inequality:
10 + 0.75n ≤ 25
subtract 10 from both sides
0.75n ≤ 25 - 10
0.75n ≤ 15
divide both sides by 0.75
n ≤ 15 / 0.75
n ≤ 20
Ultimately, Andy can rent no more than 20 DVD's in a month.

A stadium has 10,500 seats and eight VIP boxes. The stadium is divided into 12 equal sections to premium sections and 10 standard sections. A seat at the premium section cost $48 per game. AC at the standard section cost $27 per game.  how many more seats are there in each section? If all the seats in the premium section are sold out for a game how many will the stadium get from those tickets sales? PLEASE HELP 44 POINTS!
Answer:
There are 875 seats. The stadium got $168,000 from the tickets.
Step-by-step explanation:
So there is more than one question so let's break them down one by one
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
So the answers are $168,000 and 875 seats

One year, an estimated 6,955 sandhill cranes migrated in March. The next March, an estimated 3,480 sandhill cranes migrated. To the nearest percent, what is the percent change in the number of migrating cranes from the first March to the next? Decreases should be negative numbers and increases should be positive numbers. Do not include the percent in your answer
Rounding to the nearest percent, we get that the percent change in the number of migrating cranes from the first March to the next is approximately -50%.
How is a percentage calculated?To calculate the percentage, we must first divide the amount by the total value and then multiply the result by 100.
To find the percent change in the number of migrating cranes from the first March to the next, we can use the formula:
percent change = ((new value - old value) / old value) × 100%
where the old value is the number of migrating cranes in the first March and the new value is the number of migrating cranes in the next March.
Substituting the given values, we get:
percent change = ((3480 - 6955) / 6955) × 100%
Simplifying, we get:
\percent change = (-3475 / 6955) × 100%
percent change ≈ -50%
Rounding to the nearest percent, we get that the percent change in the number of migrating cranes from the first March to the next is approximately -50%.

The drawing is composed of a rectangle and a semicircle. Find the area of the figure to the nearest unit. The number on top of the figure is 10 cm and the number on the side is 22 cm
not drawn to scale. If you can help me i would appreciate it!!!
The correct option is B, The area of the figure will be the sum of the area of the rectangle and half the area of the circle is 220 cm².
The rectangle has a length of 22 cm and a width of 10 cm, so its area is:
A_rectangle = length × width = 22 cm × 10 cm = 220 cm²
A rectangle is a four-sided polygon with opposite sides parallel and equal in length. The area of a rectangle is the measure of the space that it occupies and is given by the product of its length and width.
To find the area of a rectangle, one needs to multiply the length of the rectangle by its width. For example, if the length of the rectangle is 5 meters and its width is 3 meters, the area would be 15 square meters. This is because 5 multiplied by 3 is equal to 15. In general, the formula for the area of a rectangle is A = lw, where A is the area, l is the length, and w is the width. The units of the area will depend on the units of the length and width.

The difference in length of a spring on a pogo stick from its non-compressed length when a teenager is jumping on it after θ seconds can be described by the function f of theta equals 2 times cosine theta plus radical 3 period
Part A: Determine all values where the pogo stick's spring will be equal to its non-compressed length. (5 points)
Part B: If the angle was doubled, that is θ became 2θ, what are the solutions in the interval [0, 2π)? How do these compare to the original function? (5 points)
Part C: A toddler is jumping on another pogo stick whose length of their spring can be represented by the function g of theta equals 1 minus sine squared theta plus radical 3 period At what times are the springs from the original pogo stick and the toddler's pogo stick lengths equal? (5 points)
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.

how many different 3 digit numbers can be formed from 1,3,5,7,9 if each number formed is greater than 300? distinguishable permutations
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)!
= 5!/(5-3)!
= 120/2
= 60
Therefore, there are a total of 60 different 3-digit numbers that can be formed from the number 1,3,5,7,9. However, we need to subtract the numbers that are less than 300, which are the numbers formed from the digits 1 and 3 in the hundreds place. There are 2 numbers in the hundreds place (1 and 3) and 4 numbers in the tens and ones place (3,5,7,9), so there are a total of 2*4*4 = 32 numbers less than 300. Subtracting these from the total gives us:
60 - 32 = 28
