Solve the double-ended inequality:
2x-5<4x+2<2x-3
Answer: _ _ x _ _
Answer with a number in the first box, inequality in the second box, than after the x an inequality in the 3rd box and a number in the last box.
EG 5 > x > 18
The solution of the double-ended inequality is -7/2 < x < -5/2
Solving Linear InequalitiesFrom the question, we are to solve the doubled ended inequality.
The given inequality is
2x - 5 < 4x + 2 < 2x -3
From the inequality, we can write that
2x - 5 < 4x + 2 and 4x + 2 < 2x - 3
Now, we will solve each of the inequalities separately
Solving 2x - 5 < 4x + 2
Add 5 to both sides
2x - 5 + 5 < 4x + 2 + 5
2x < 4x + 7
Subtract 4x from both sides
2x - 4x < 4x - 4x + 7
-2x < 7
Divide both sides by -2 and reverse the sign
x > -7/2
-7/2 < x
Solving 4x + 2 < 2x - 3
Subtract 2x from both sides of the equation
4x - 2x + 2 < 2x - 2x -3
2x + 2 < -3
Subtract 2 from both sides
2x + 2 -2 < -3 - 2
2x < -5
Divide both sides by 2
x < -5/2
Putting the two solutions together, we get
-7/2 < x and x < -5/2
-7/2 < x < -5/2
Hence, the solution is -7/2 < x < -5/2

Can anyone write the equation of the graph?
The equation of the graph is f(x) = |x - 3| + 5
How to find the equation of the graph line?Given that the graph is an absolute value graph
We start by calculating the vertex of the graph
In this case, the graph has it minimum point located at the coordinate (3, 5)
This coordinate can then be interpreted as
(h, k) = (3, 5)
As a general rule, the general representation of the equation of an absolute value function is f(x) = |x - h| + k
Substitute the known values in the above equation
So, we have the following equation

If $3000 is invested at tan interest rate if 4.8%, compounded hourly for two years what is the ending balance?
The final balance is $97,920.
Compound interest is calculated on the principal as well as the interest accumulated over the previous period. It differs from simple interest in that interest is not added to the principal when calculating interest for the following period.
Given this, The principal is $3000.
Interest rate = 4.8%
Time = 2 years We must find the final balance.
The end balance formula is
C = P[ 〖(1+r)〗^n – 1]
C = 3000[ 〖(1+4.8)〗^2 – 1]
C = 3000 [ 〖(5.8)〗^2 – 1]
C = 3000 [ 33.64 – 1]
C = 3000 ( 32.64)
C = 97,920
Therefore the ending balance is $97,920

The function y = f(x) is graphed below. What is the average rate of change of the function f(x) on the interval -9 ≤ x ≤ -4?
Answer:
2.4
Step-by-step explanation:
You want the average rate of change on the interval [-9, -4] for the graphed function.
Average rate of changeThe average rate of change (m) is the slope of the line between the points at the ends of the interval. For function f(x) on interval [a, b], this is ...
m = (f(b) -f(a))/(b -a)
ApplicationFor the function f(x) on the interval [-9, -4], the average rate of change is ...
m = (f(-4) -f(-9))/(-4 -(-9)) = (-4 -(-16))/5 = 12/5 = 2.4
The average rate of change of f(x) on [-9, -4] is 2.4.

the graph of the line is shown below .
In the question ,
point on the line and slope of the line is given
So , equation will be
Part(1)
(-6, -3), m = -1
(y -(-3)) = -1(x -(-6))

A total of 549 of people at the convention are bored by the cable news
How to determine the number of people at the convention that are bored?From the question, we have the following parameters that can be used in our computation:
Not bored = 122
Bored = 9/11 of the people
This means that
Not bored = 1 - Bored
So, we have
Not bored = 1 - 9/11
Evaluate
Not bored = 2/11
Recall that Not bored = 122
So, we have
2/11 * x = 122
Where x = the number of people
This gives
x = 122 * 11/2
Evaluate
x = 671
Recall that
Bored = 9/11 of the people

The number of balcony seats sold is 110
Finding Unknown quantity using Linear equation:
The linear equation is an equation that is used to find an unknown quantity or an unknown number. In this, we will represent the Uknown value with a variable like x, y, z, etc.
Here we have
Tickets for a community theater cost $11 for each main-floor seat
and $6 for each balcony seat.
There are 400 seats on the main floor, which are sold out for the evening performance
The total revenue from ticket sales was $5060.
Here we don't know the number of balcony seats.
Let us assume that number of balcony seats = x
Then total revenue = 400(11) + 6x = 5060
=> 4400 + 6x = 5060
=> 6x = 5060 - 4400
=> 6x = 660
=> x = 110

The amount of energy that the ball will have at 10 m/s is; 600 J
How to find the energy from velocity?From the given table, we see that when the velocity is 2 m/s, then the energy is 20 J.
If we take the square of the velocity, we get 2² = 4.
Thus, we need to multiply 4 by 6 to get the energy that is equal to 24 as 4 * 6 = 24.
Similarly;
For velocity equal to 3 m/s, the energy is given as:
E = 6 * 3²
E = 54 J
Thus, the general formula to find the energy is given as:
E = 6 * v²

XR is a tangent to circle O at X.
We have to find the measure of ∠ YXR.
Draw the radii XO and OY to form the isosceles triangle XOY.
We know that the radius of the circle is perpendicular to the tangent.
Hence, ∠OXR = 90 degrees.
Consider the triangle XOR, we know that XO and OY are the radii of the triangle and hence equal.
Let, ∠ OXY = OYX = x
Hence,
110 + x + x = 180 degrees

a) In any given experiment or trial, there is a probability that either an event occurs or it does not. The probability of the occurrence of an event lies between 0 and 1.
The event E of a sample space S is said to have occurred if the outcome ω of the experiment is such that ω ∈ E. However if the outcome ω is such that, ω ∉ E we say that the event has not occurred.
Let us take the example of playing cards. Here the event E is drawing a face card. If you draw a king of spades, we say the event E has occurred. However, if you draw an eight of clubs, we say the event E has not occurred.
b) The probability of an event is equal to the events relative frequency in the population of possible events that can occur.
An event’s relative frequency is a number between 0 and 1, so the event’s probability is from 0 to 1.
For example, when someone says that the probability it raining today is high, you understand that they mean that there is a high chance that it will rain.
But what if someone says that the probability of something happening is very low? You understand that the person means that the event may not occur at all. In mathematics, we define probability in a similar sense.

Probability is the measure of uncertainty of any event (any phenomenon happened or bound to happen).

a frustum is made by removing a small cone from a similar large cone. The height of the small cone is quarter of the height of the large cone. Find the volume of the frustum.
Height of large cone =12
radius of large cone =6
The volume of a frustum is equal to 445.3785 cubic units.
How to calculate the volume of a cone?Mathematically, the volume of a cone can be calculated by using this formula:
Volume of a cone = 1/3 × πr²h
Where:
h represents the height of a cone.r represents the radius of a cone.For the volume of the large cone, we have the following:
Volume of large cone = 1/3 × πr²h
Volume of large cone = 1/3 × 3.142 × 6² × 12
Volume of large cone = 3.142 × 36 × 4
Volume of large cone = 452.448 cubic units.
Since the height of the small cone is quarter of the height of the large cone, we have:
Height of small cone = 1/4 × 12 = 3 units.
Radius of small cone = 12/18 = 3/2 = 1.5 units (similar triangles by AAA).
For the volume of the small cone, we have the following:
Volume of small cone = 1/3 × πr²h
Volume of small cone = 1/3 × 3.142 × 1.5² × 3
Volume of small cone = 3.142 × 2.25
Volume of small cone = 7.0695 cubic units.
Mathematically, we know that the volume of a frustum is made by subtracting the volume of a small cone from the volume of a similar large cone cone:
Volume of the frustum = Volume of large cone - Volume of small cone
Volume of the frustum = 452.448 - 7.0695
