The true statement about the sentence 'sample of gas is enclosed in a container of fixed volume' are:
If the container is cooled, the gas particles will lose kinetic energy and temperature will decrease. If the gas particles move more quickly, they will collide more frequently with the walls of the container and pressure will increase.What will happen to 'sample of gas is enclosed in a container of fixed volume?When a sample of gas is been enclosed in a container of fixed volume then then if the container temperature is been reduced then the kinetic energy of the gas will reduce.
Therefore the first and the third option are correct.

Find the slope between the points
below. Simplify your answer.
(-10, 5) and (14,-3)
Slope between the points (-10, 5) and (14,-3) is -1/3.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
We need to find slope between points (-10, 5) and (14,-3)
m=-3-5/14+10
m=-8/24
m=-1/3
Hence, slope between the points (-10, 5) and (14,-3) is -1/3.

The geometric mean of a number and nine times the number is 30. What is the number?
For the given geometric mean of a required number and nine times the required number is 30 then the required number is equal to 10.
As given in the question,
Geometric mean GM = 30
Let us assume the first number is x
and second number i.e. 9 times of the first number is 9x
By the formula GM = [tex]\sqrt{x.y}[/tex]
Now putting the value
30 = [tex]\sqrt{x.9x}[/tex]
30 = [tex]\sqrt{9x^{2} }[/tex]
30 = 3x (∴ square root of 9 is 3 and sq root of x² is x)
10 = x (by dividing both the side by 3)
Therefore, for the given geometric mean of a required number and nine times the required number is 30 then the required number is equal to 10.

factorise x squared - 6x
The quadratic expression can be factorized to:
x*(x - 6)
How to factorize the expression?Here we have the expression:
x^2 - 6x
To factorize this, first, we need to find the roots, which are the solutions of:
x^2 - 6x = 0
Notice that one of the solutions is trivial, and it is x = 0.
If now we assume that x ≠ 0 and divide both sides by x, we get:
x - 6 = 0
x = 6
That is the other solution.
Now, for a square polynomial with the roots a and b, the factorized form is:
(x - a)*(x - b)
In this case, the roots are 0 and 6, then:
x^2 - 6x = (x - 0)*(x - 6) = x*(x - 6)

Given the following exponential function, identify whether the change represents
growth or decay, and determine the percentage rate of increase or decrease.
y = 90(1.02)
The exponential equation represents an exponential growth because the rate of decay is 1.02 which is greater than 1.
y = 90(1.02)^x
The general form equation is:
y(x)= a(1+r)^x such that r is the decay percent.
on comparing,
1 + r = 1.02
r = 1.02 - 1
r = 0.02
converting into percent
r = 0.02 * 100

Step-by-step explanation:
Since it's given a graph, we can use rise over run to figure it out
We pick 2 points that are integers on the graph , which means two points on the graph that the line goes through
Example- I picked (-3, 2) and (0, -3), you can indicate them so you don't forget or anything
We now draw a triangle formed by those two points (a line that goes from (-3, 2) to (-3, -3) and a line from (0, -3) to (-3, -3)
Rise (Which is the height of the triangle you just drew) is 5 units, but it's going down, so -5
The base (Run) is 3 units. Using rise/run, the slope is -5/3
The y-intercept, which is at the point where the graph crosses the y-axis, is -3.
The slope intercept form is y=mx+b, where m = slope and b = y-intercept, so the equation of the graph is y = -5/3x -3

What is probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The likelihood that an event will occur increases with its probability.A straightforward illustration is tossing a fair (impartial) coin.The chance of both outcomes ("heads" and "tails") is equal because the coin is fair, "heads" is more likely than "tails," there are no other conceivable outcomes, and the likelihood of either outcome is half .acc to our question-

What is the rate of change of the function y = 5x + 4?
Answer:
The slope of y = 5x - 4 is 5.
Notice that the equation, y = 5x - 4, of the line is written in the form y = mx + b. Thus, it is in slope-intercept form. When the equation of a line is in slope-intercept form, we know that the slope of the line is equal to m, the coefficient of x.
In y = 5x - 4, the coefficient of x is 5. Thus, the slope of the line, y = 5x - 4, is 5.

What do you mean by right angle triangle?
A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or formerly rectangled triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.
According to data in the diagram of the given question:
We have :
The ΔJKL, ΔRKS and ΔRTS are right-angle triangle.
The length of RK=3 and KS=4
We are using pythagoras theorem for determine the length of RS,
(RK)²+(KS)²=(RS)²
(3)²+(4)²=(RS)²
9+16=(RS)²
25=(RS)²
(5)²=(RS)²
RS=5
∴ The the length of RS is 5.
Now, we need to find the length of JK,
JK=2(RK)=2(3)=6
JK=6 [Because RK is midpoint of the side JK]
We have given value of KS=4 and the side KS is the opposite side of RT,
So, that's why the value of RT=4.
Now, we will find the perimeter of ΔJKL,
JK=6, KL=8 and we need to find the side JL,
(JK)²+(RL)²=(JL)²
(6)²+(8)²= (JL)²
36+64=(JL)²
100=(JL)²
(10)²=(JL)²
JL=10
The perimeter of the triangle ΔJKL,
Perimeter=6+8+10=24
Therefore, the perimeter of the triangle is 24.

The rate at which the height of the water changes when the water is 1m deep is; dh/dt = 1.5m/min
We are given;
width; w = 3m
Height; h = 4m
Length of trough; L = 10m
According to similar triangle property; w =3/4h
volume of water; V = 1/2×w×h×L = 1/2 × 3/4h × h × 10 = 15/4 h²
Differentiate using chain rule for both sides with respect to t gives;
dV/dt = (1/2)(15/2)h(dh/dt).
Now, we are given dV/dt = 5m³/min and we want to find the rate at which the height of water changes when the water is 1 m deep.

A. 10 g/cm³
B. 2.5 cm³/g
C. 4 g/cm³
D. 4 cm³/g
E. 0.25 g/cm³
The density is the ratio of mass to volume of an object thus the density of the given test sample is 4 g/cm³ thus option (C) will be correct.
What is density?Density or mass density is the mass of any object per volume.
For example, if the metal has a 100 kg mass and an area of 10-meter square then 100/10 = 10 kg/meter square will be the density of the given object.
Density can be uniform or non-uniform.
Density is the division of mass and volume and the mass must be for the quantity of the volume only.
Given that,
Mass = 10 g
Volume = 2.5 cm³
Density = 10/2.5 = 4 g/cm³
