intiderivatives & Indefinite Integrals (x^3-2)dx
The final solution of the given integral ∫ ([tex]x^3[/tex] - 2) dx is ([tex]x^4[/tex])/4 - 2x + C.
To integrate ∫ (x^3 - 2) dx, we use the power rule of integration, which states that ∫[tex]x^n[/tex] dx = ([tex]x^{(n+1)}[/tex])/(n+1) + C, where C is the constant of integration.
In this case, we have [tex]x^3[/tex] as the inside function, so we apply the power rule by raising the exponent by 1 and dividing by the new exponent. This gives us ([tex]x^4[/tex])/4 + C as the antiderivative.
However, we also have the constant term -2. To integrate a constant term, we add it as a separate term to the antiderivative. So the final solution is ([tex]x^4[/tex])/4 - 2x + C.

The possible values of x, so that the relation does not form a function, is given as follows:
x = -2 or x = -5.
When does a relationship represents a function?To verify whether a relation represents a function, we need to observe if each input is mapped to only one output.
The points for the function in this problem are given as follows:
(-2,5),(-5,9),(x,-3)
The meaning of each point is that:
(-2,5): input of -2 is mapped to an output of 5.(-5,9): input of -5 is mapped to an output of 9.(x, -3): input of x is mapped to an output of -3.The relation is not a function, meaning that the value of x is either of x = -2 or x = -5, which are already mapped to another value of x.
Missing InformationThe problem asks for the values of x so that the relation is not a function, considering the three points that were given on the problem.

What is an example of a two-step inequality?
A two-step inequality is an inequality that requires more than one step to solve. An example of a two-step inequality is to solve the inequality 2x - 3 ≥ 5.
Example: Solve the inequality 2x - 3 ≥ 5
Step 1: Isolate the variable by adding 3 to both sides: 2x ≥ 8
Step 2: Divide both sides by 2: x ≥ 4
In this example, the first step is to isolate the variable x by adding 3 to both sides of the inequality. In the second step, we divide both sides by 2 to get the final solution of x ≥ 4.
It's worth noting that this inequality has a solution that is an interval, it is x ≥ 4, which means that all values of x that are greater or equal to 4 are solutions of the inequality.
It's important to keep in mind that inequalities may require multiple steps to solve and may not always have a single solution. It's important to check the solution by substituting back into the inequality to make sure it holds true.

There are 80 dogs and 20 cats in the animal shelter.
The ratio of dogs to cats is 4:3. This means for every 4 dogs, there are 3 cats. We know that there are 40 more dogs than cats.
To calculate the number of each animal, we can set up the equation 40 = 4x - 3x, where x represents the number of cats.
After solving the equation, we get x = 20. This means that there are 20 cats in the animal shelter. To find the number of dogs, we can use the ratio. We know that for every 4 dogs, there are 3 cats. So, for 20 cats, there must be 4 × 20 = 80 dogs.

A train left Vicky' town and traveled for 4 hour and 50 minute to Wildgrove. Then it traveled 2 hour and arrived in Wetminter at 12:28 P. M. What time did the train leave Vicky' town?
The train left Vicky's town at 7:38 A.M. after traveling for 4 hours and 50 minutes to Wildgrove.
To calculate this, we need to work backward from the arrival time in Westminster. The train arrived in Wetminter at 12:28 P.M. and it took 2 hours to travel from Wildgrove to Westminster. So, if we subtract 2 hours from 12:28 P.M., we get 10:28 A.M.
Next, we need to take into account the time it took for the train to travel from Vicky's town to Wildgrove. The train traveled for 4 hours and 50 minutes to Wildgrove.
So, if we convert 4 hours and 50 minutes to minutes (4*60+50 = 290 minutes) and subtract it from 10:28 A.M., we get 7:38 A.M. This is the time the train left Vicky's town.

Write an exponential function that models the info below.
An initial value of 1,425 increasing at a rate of 5%.
Answer:
y = 1425 * (1 + 0.05)^x
Step-by-step explanation:
An exponential function of the form y = a * b^x can be used to model exponential growth or decay, where a is the initial value, b is the base (growth or decay factor), and x is the time period. In this case, the initial value is 1,425 and the rate of increase is 5%. We can write this as an exponential function as follows:
y = 1425 * (1 + 0.05)^x
where y is the final value after x time periods, and x is the number of time periods (in years, for example). To find the value of the function after x time periods, you can substitute the value of x into the equation.

A right triangle is any triangle that has a 90-degree angle.
A 30-60-90 triangle is a special type of right triangle that has a 30-degree angle and a 60-degree angle in addition to the right angle.
The side opposite the 30-degree angle is called the shorter leg.
The side opposite the 60-degree angle is called the longer leg.
The side opposite the right angle of 90 degrees is called the hypotenuse.
The hypotenuse is twice the shorter leg.
The longer leg is √3 times the shorter side.
if the length of the shorter leg is given, then these properties are used to find the longer side and the hypotenuse.
However, the 30-60-90 properties hold no matter which side is provided.
If the length of the hypotenuse is given, divide it by 2 for the shorter leg. Then multiply that result by √3 to get the length of the longer leg.
