The baseball thrown upwards will experience a change in its velocity while its acceleration will be constant.
A type of motion known as upward motion involves an item moving up against the pull of gravity.
The opposing force of gravity causes an object to go upward with a decreasing vertical velocity as it does so. When the item reaches its maximum height, its velocity ultimately zeroes out. The velocity starts to rise as the object starts to descend and eventually reaches its highest point just before impact with the ground.
The object's acceleration during its upward motion is constant and always points downward. Hence, it follows that an item moving upwards will experience a change in velocity but not in acceleration.

The average speed of molecules in an ideal gas is ^-u=4/√π(M/2RT)^3/2 ^[infinity]∫0 v^3e^-Mv^2/(2RT) dv where M is the molecular weight of the gas, R is the gas constant, T is the gas temperature, and is the molecular speed. Show that v= √8 RT/ πM
The shown that v= √8 RT/ πM.
To show that v= √8 RT/ πM, we will first rewrite the given integral. It is:
$$\left(\dfrac{-u}{4}\right)=\dfrac{1}{\sqrt\pi}\left(\dfrac{M}{2RT}\right)^{\frac{3}{2}}\int_{0}^{\infty}v^{3}e^{\frac{-Mv^{2}}{2RT}}dv$$Let's solve the integral first. We'll use the integral rule:
$$\int xe^{ax^{2}}dx=\dfrac{1}{2a}e^{ax^{2}}+C$$
So, the integral from the given formula can be re-written as:
$$\begin{aligned}&\int_{0}^{\infty}v^{3}e^{\frac{-Mv^{2}}{2RT}}dv \\ &\quad =-\dfrac{2RT}{M}\int_{0}^{\infty}\left(-\dfrac{Mv^{2}}{2RT}\right)\cdot v\cdot e^{\frac{-Mv^{2}}{2RT}}dv \\ &\quad =-\dfrac{2RT}{M}\int_{0}^{\infty}vde^{\frac{-Mv^{2}}{2RT}} \\ &\quad =-\dfrac{2RT}{M}\left[ve^{\frac{-Mv^{2}}{2RT}}\right]_{0}^{\infty} \\ &\quad =\dfrac{2RT}{M}\cdot 0+ \dfrac{2RT}{M}\cdot \infty \\ &\quad =\infty\end{aligned}$$This means that the integral of the formula is infinity. Therefore, to make the equation equal to the given answer, the given formula for the average speed of molecules in an ideal gas must be equated with the most probable speed. The most probable speed of the gas is the speed at which the likelihood of finding molecules is the highest. It is given by the following formula:
$$v_{mp}=\sqrt{\dfrac{2RT}{M}}$$Therefore,
$$v_{mp}=\sqrt{\dfrac{2RT}{M}}=\sqrt{\dfrac{8RT}{4M}}=\sqrt{\dfrac{8RT}{\pi M}}$$Hence, we have shown that v= √8 RT/ πM.

The z value when making 98% confidence interval for p will be 2.33.
When making a confidence interval for a proportion, we use the standard normal distribution, and the value of z depends on the level of confidence we want to achieve.
In this case, we want to make a 98% confidence interval, which means that we want to be 98% confident that the true proportion falls within our interval.
To determine the value of z, we can use a z-table or a calculator. The z-value corresponding to a 98% confidence level is 2.33. Therefore, we use 2.33 as our value of z when making a 98% confidence interval for p.
It is not impossible to make a 98% confidence interval, and the value of z is not 2.88. The z-value of 2.88 corresponds to a much higher confidence level of approximately 99.5%. Using a higher confidence level means we can be more confident that our interval contains the true proportion, but it also means that our interval will be wider, which reduces its precision.

What is the secant tangent angleThe secant tangent angle is the angle formed by a tangent and a secant that intersect outside of a circle. The measure of the secant tangent angle can be found using the following formula:
θ = 1/2 (arc EB - arc BD)
where arc EB and arc BD are the measures of the arcs intercepted by the secant and tangent, respectively.
From the question,
θ = m∠NXK = 4x + 6
arc EB = 8x - 13
arc BD = 70° + (6x - 1) = 69 + 6x
4x + 6 = 1/2[69 + 6x - (8x - 13)]
4x + 6 = 1/2(69 + 6x - 8x + 13)
4x + 6 = 1/2(82 - 2x)
4x + 6 = 41 - x
4x + x = 41 - 6 {collect like terms}

What is the solution set of the equation (show work)
The solution set of the equation x/3 = 8/(x + 2) when calculated is x = -6 or x = 4
Calculating the solution set of the equationGiven the following equation
x/3 = 8/(x + 2)
Cross multiply
x(x + 2) = 24
To find the solution set of x(x + 2) = 24, we need to solve for x by simplifying the left-hand side of the equation and then factoring it.
x(x + 2) = 24
Expanding the left-hand side, we get:
x² + 2x = 24
Subtracting 24 from both sides, we get:
x² + 2x - 24 = 0
Now we can factor the quadratic expression on the left-hand side:
(x + 6)(x - 4) = 0
Using the zero product property, we know that the product of two factors is zero if and only if at least one of the factors is zero.
Therefore, we can set each factor equal to zero and solve for x:
x + 6 = 0 or x - 4 = 0
Solving for x, we get:
x = -6 or x = 4
So, the solution set is { -6, 4 }.
These are the values of x that make the equation true when plugged in.

g in the aftermath of a car accident, it is concluded that one driver slowed to a halt in 19 seconds while skidding 1700 feet. if the speed limit was 60 miles per hour, can it be proved that the driver had been speeding? (hint: 60 miles per hour is equal to 88 feet per second.) we can guarantee that at some time from when the driver first pressed on the brake to when the car came to a complete stop the car was traveling mph. therefore we (can/can not) conclude that the driver was speeding from the information given.
Yes, it can be proved that the driver had been speeding.
The driver had been speeding since the distance traveled during the 19-second skid is greater than the distance the car would have traveled at 60 mph in the same time. This implies that the driver was traveling at a higher speed than the speed limit before braking.
To explain further, we can calculate the distance a car traveling at 60 mph would cover in 19 seconds, which is 1,672 feet (60 mph = 88 fps, 19 seconds x 88 fps = 1,672 feet). However, the car in question skidded for 1700 feet before coming to a complete stop, which is greater than the distance it would have traveled at 60 mph in the same time. This implies that the driver was traveling at a higher speed than the speed limit before braking. Therefore, it can be concluded that the driver was speeding.

Sandesh sold 15kgs of apples for 2100rs and gained 12%. At what price per kg should he sell to gain 20% ?
As per the given percentage, Sandesh should aim to sell his apples at 250rs per kg in order to gain 20% profit.
Let C be the cost of the 15kgs of apples. Sandesh gained 12%, so his profit is 0.12C. We know that Sandesh sold the apples for 2100rs, so we can write an equation:
C + 0.12C = 2100
Simplifying this equation gives:
1.12C = 2100
Dividing both sides by 1.12 gives:
C = 1875
So Sandesh's cost for 15kgs of apples was 1875rs.
Now, we need to find the selling price per kg of apples that Sandesh should aim for in order to gain 20% profit. Let P be the selling price per kg of apples.
Since Sandesh wants to gain 20% profit, his selling price per kg of apples needs to be his cost plus 20% of his cost, or 1.2 times his cost.
So we can write another equation:
1.2C = 15P
Substituting the value of C we found earlier, we get:

The answer of the given question based on the circle on finding the measure of the manilla angle the answer will be the measure of the manila angle is 110° degrees.
What is Circle?A circle is closed, two-dimensional shape that consists of all points in plane that are equidistant from given point, called center of the circle. The distance from center to any point on circle is called radius of the circle.
The circumference of circle is distance around the circle, and it is equal to 2π times radius. Circles are fundamental concept in geometry and are used in many fields, like physics, engineering, and architecture. They are also used to represent cycles, cycles of time, and the cyclical nature of life.
If the entire pink arc measures 200° degrees and the entire blue arc measures 50° degrees, then the sum of the measures of the three arcs (pink, blue, and manila) is 360° degrees, which is the total measure of a circle.
To find the measure of the manila angle, we need to subtract the measures of the pink and blue arcs from 360° degrees:
360° degrees - 200° degrees - 50° degrees = 110° degrees
Therefore, the measure of the manila angle is 110° degrees.

what is the implication when the determinant of a matrix is almost 0 and how does this affect the sensitivity of the solution to the change of constants in the system?
Answer:
When the determinant of a matrix is almost 0, it means that the matrix is close to being singular, which means that its inverse does not exist or is very close to not existing. This has important implications for the solution of systems of linear equations represented by the matrix.
Specifically, if the determinant of a matrix is almost 0, then the matrix is almost singular, which means that its columns are almost linearly dependent. This, in turn, means that the system of equations represented by the matrix has almost linearly dependent equations, which can lead to multiple solutions or no solutions at all.
In terms of the sensitivity of the solution to changes in the constants of the system, a small change in the constants can lead to a large change in the solution when the determinant of the matrix is almost 0. This is because the inverse of the matrix is very sensitive to changes in its entries when the determinant is almost 0.
For example, consider a system of linear equations represented by a matrix A with determinant very close to 0, and let b be the vector of constants on the right-hand side of the equations. Then, the solution to the system can be approximated by the product of the inverse of A (if it exists) and b, that is:
x = A^(-1) b
However, if A is almost singular, then its inverse is very sensitive to changes in its entries, and a small change in b can lead to a large change in x. This can make the solution to the system unreliable and unstable, and can be a source of numerical errors in computations.

The solutions for the systems of inequalities are:
a) (0, -50), (0, -100), (0, -125)
b) (0, 20), (0, 23) , (0, 24).
How to identify 3 solutions of each system?
When we have a system of inequalities, a solution is a point (x, y) that solves both ienqualities at the same time.
The first one is:
y ≤ x - 8
y < -3x - 9
Here y must be smaller than x, then we can define x like x = 0, and really small values for y, like y = -50, replacing that we will get:
-50 ≤ 0 - 8 = -8
-50 < - 3*0 - 9 = -9
Both of these are true, so (0, -50) is a solution, and trivially, other solutions of the system of inequalities can be things like (0, -100) and (0, -125) are other two solutions.
For the second system:
y > 5x + 1
y > 3
Let's do the same thing, x = 0 and y gets really large values, like y = 20
20 > 5* + 1 = 1 this is true.
20 > 3 this is true.
so (0, 20) is a solution, and also are (0, 23) and (0, 24).

So the area of the cylinder's base is 25π square units.
c. The volume of a cylinder is calculated using the formula V = πr^2h, where V is the volume, r is the radius of the base, and h is the height of the cylinder.
Substituting the values given, we get:
V = πr^2h = π(5^2)(4) = 100π
So the volume of the cylinder is 100π cubic units.
A cylinder is a three-dimensional object with a circular base and straight sides that rise to a circular top. The area of a cylinder is the total amount of space on the surface of the cylinder. It can be calculated by finding the sum of the areas of the two circular bases and the curved surface area in between.
The formula for finding the surface area of a cylinder is A = 2πr² + 2πrh, where "r" is the radius of the circular base, "h" is the height of the cylinder, and "π" is a constant value of approximately 3.14159. To calculate the area of a cylinder with a radius of "r" and height of "h", we first find the area of the circular base by using the formula for the area of a circle: A_base = πr².

Step-by-step explanation:
Jen’s assignment is to read at least 85 pages of a novel. Jen has read 31 pages. How many pages p does Jen have left to read? Write an inequality that represents this situation. Then solve the inequality
Jen has 54 pages left to read to meet her assignment requirement.
The inequality that represents this situation is p ≥ 85 - 31
To find how many pages Jen has left to read, we can subtract the number of pages she has already read from the minimum number of pages she needs to read.
The minimum number of pages Jen needs to read is 85, and she has already read 31 pages. So, the number of pages she has left to read, p, can be found by:
p = 85 - 31
p = 54
Therefore, Jen has 54 pages left to read.
To represent this situation with an inequality, we can use:
p ≥ 85 - 31
This inequality states that the number of pages Jen still needs to read, p, must be greater than or equal to the difference between the minimum number of pages she needs to read (85) and the number of pages she has already read (31).
Solving for p:
p ≥ 85 - 31
p ≥ 54
This means that Jen must read at least 54 more pages to meet her assignment requirement.

QUESTION 3
A pan of brownies is cut into eight equal rows. Two thirds of one of those rows is what fraction of the whole pan.
Answer:
1/12
Step-by-step explanation:
Each row would be 1/8 of the whole pan. Now multiply 1/8 by 2/3.
Multiply the numerators: 1*2=2
Multiply the denominators: 8*3=24
Your answer: 2/24 or 1/12 simplified (dividing both top and bottom by 2)
Hope this helps. :)

...A store pays $261 for a diving board and marks the price up by 45%. What is the amount of the mark-up?
Answer:
If the store marks up the price of the diving board by 45%, the selling price will be 100% + 45% = 145% of the cost price.
Let's calculate the selling price:
Selling price = Cost price + Mark-up
Mark-up = Selling price - Cost price
Mark-up = (145% of cost price) - cost price
Mark-up = 0.45 * cost price
We know that the store paid $261 for the diving board, so:
Mark-up = 0.45 * $261 = $117.45
Therefore, the amount of the mark-up is $117.45.
well, what's 45% of 261?
