Use areas to evaluate 4xdx where 0 < a
Integration is basically used to find the areas of the two-dimensional region and computing volumes of three-dimensional objects.
What is integration?
In mathematics, an integral lends numerical values to functions to represent concepts like volume, area, and displacement that result from combining infinitesimally small amounts of data. Integration is the action of locating integrals.
Differentiation is the opposite of integration.
In other words, reversing the differentiation process merely results in integration. The example below demonstrates it:
dy/dx = 2x since y = x2 Consequently,
(dy/dx) dx = 2x dx = x2.
Together, and dx represent the integration of the function with respect to x.
The anti-differentiation is another name for integration. In this procedure, we are given a function's derivative and asked to determine the function (i.e., primitive). We are aware that cos x is the differentiation of sin x.

There are four types of social norms that can help inform people about behavior that is considered acceptable: folkways, mores, taboos, and law.
Social values are the focus of sociology. Cultural norms known as social values describe the overall well-being thought desirable for a structured social existence. These presumptions concern what is morally correct and significant for society. They provide social structures and behavior its ultimate meaning and legitimacy. They are ideals or abstract feelings. "Equality of opportunity" is a prime illustration of social value. It is frequently regarded as a desirable end in and of itself.

In the lab, Linda has two solutions that contain alcohol and is mixing them with each other. Solution A is 50% alcohol and Solution B is 10% alcohol. She us
400 milliliters of Solution A. How many milliliters of Solution B does she use, if the resulting mixture is a 20% alcohol solution?
We can start by using the concept of percentage concentration, which states that the percentage of alcohol in a solution is equal to the number of milliliters of alcohol in the solution divided by the number of milliliters of the solution, multiplied by 100.
Let's call the number of milliliters of Solution B that Linda uses x.
We know that:
Solution A is 50% alcohol, so it contains 50/100 = 0.5 = 1/2 of alcohol.
Solution B is 10% alcohol, so it contains 10/100 = 0.1 = 1/10 of alcohol.
The resulting mixture is a 20% alcohol solution.
Linda uses 400 milliliters of Solution A.
We can set up an equation using the percentage concentration concept and the information provided:
(400 * 1/2) + (x * 1/10) = (x + 400) * (20/100)
Solving for x:
200 + x/10 = (x + 400) * 0.2
x/10 = (x + 400) * 0.2 - 200
x/10 = x * 0.2 + 80
9x/10 = x * 0.2 + 80
9x = x*2 + 800
x = 800/8 = 100
So, Linda uses 100 milliliters of Solution B to make the resulting mixture a 20% alcohol solution.
Use left rectangles and Δ x = 0.5 to approximate the area under f ( x ) = 2 x 2 + 6 from x = 2 to x = 4 . Give one decimal place in your answer.
The approximation of the area under the curve f(x) = [tex]2x^2 + 6[/tex] from x = 2 to x = 4 using left rectangles and a step size of Δx = 0.5 is 60.5 square units to one decimal place.
To approximate the area under the curve f(x) = [tex]2x^2 + 6[/tex] between x = 2 and x = 4 using left rectangles and a step size of Δx = 0.5, we have to divide the interval [2, 4] into a number of sub-intervals of width 0.5 and evaluate the function at the left endpoint of each sub-interval.
First find the number of steps: (4-2)/0.5 = 4
The x-coordinates for the left endpoints of each sub-interval are: 2, 2.5, 3, 3.5, 4
We evaluate the function f(x) = [tex]2x^2 + 6[/tex] at each of these left endpoints and multiply the result by the width of the sub-interval (0.5) to find the area of each rectangle.
For [tex]x = 2[/tex], [tex]f(x) = 2(2)^2 + 6 = 14[/tex]
Area = 0.5 * 14 = 7
For [tex]x = 2.5, f(x) = 2(2.5)^2 + 6 = 19.5[/tex]
Area = 0.5 * 19.5 = 9.75
For [tex]x = 3, f(x) = 2(3)^2 + 6 = 24[/tex]
Area = 0.5 * 24 = 12
For [tex]x = 3.5, f(x) = 2(3.5)^2 + 6 = 29.5[/tex]
Area = 0.5 * 29.5 = 14.75
For [tex]x = 4, f(x) = 2(4)^2 + 6 = 34[/tex]
Area = 0.5 * 34 = 17
The sum of the areas of these rectangles is 7 + 9.75 + 12 + 14.75 + 17 = 60.5
Therefore, the approximation of the area under the curve f(x) = [tex]2x^2 + 6[/tex] from x = 2 to x = 4 using left rectangles and a step size of Δx = 0.5 is 60.5 square units to one decimal place.

A stationary point of a function f(x) is a point where the derivative of f(x) is equal to 0. These points are called “stationary” because at these points the function is neither increasing nor decreasing.
How do you find stationary points f XY?Once we have identified the dy dx = 0 solutions, we may utilise the first derivative to ascertain the characteristics of the stationary points. Think about the equation y = x2 + 1.
By differentiating and setting the derivative to zero, we may determine that there is a stationary point at x = 0 since dy dx = 2x = 0. Recall that placing f by x and f by y equal to zero will reveal the location of a function f's stationary point.
In this situation, partial differentiation with regard to x while treating y as a constant results in three x squared plus six x. Any stationary point's nature can be ascertained by introducing its x coordinate into the second derivative of the function, f. (x).

The sum of two numbers is 1476890. If the difference between the two numbers is 1500, what is the greater number ?
Let's call the two numbers x and y. We know from the problem statement that:
x + y = 1476890
y - x = 1500
To find the greater number, we can use the second equation to solve for one of the variables, and then substitute it into the first equation.
y = x + 1500
Now we can substitute this expression for y into the first equation:
x + (x + 1500) = 1476890
2x + 1500 = 1476890
2x = 1476890 - 1500
2x = 1475390
x = 1475390/2

R = ±1/√(C-a*x) + K
where K is an arbitrary constant.
To find the constant of integration, we use the initial condition. We plug in the initial values for x and R to find the constant of integration. For example, if x = 0 and R = 2, then we get
2 = ±1/√(C-0) + K
2 = ±1/√C + K
K = 2±1/√C
Therefore, the solution to the differential equation is given by R = ±1/√(C-a*x) where C is the constant of integration.

In a particular game, a fair die is tossed. If the number of spots showing is either 4 or 5, you win $1, if the number of spots showing is 6, you win $4, and if the number of spots showing is 1, 2, or 3, you win nothing. Let X be the amount that you win. The expected value of X is
(a) $0.00
(b) $1.00
(c) $2.50
(d) $4.00
(e) $6.00
The amount that you when a fair dice is tossed (showing is either 4 or 5, you win $1, if the number of spots showing is 6, you win $4, and if the number of spots showing is 1, 2, or 3, you win nothing) is $1.00
Given,
when you get either 4 or 5, the reward = $1
when you get either 6, the reward = $4
when you get 1, 2, or 3, the reward = $0
We know that,
Probability of getting 6 = 1/6
Probability of getting 4 = 1/6
Probability of getting 5 = 1/6
Probability of getting 1 = 1/6
Probability of getting 2 = 1/6
Probability of getting 3 = 1/6
Therefore,
[tex]X = \frac{1}{6}* 4 + \frac{1}{6}* 1 +\frac{1}{6}* 1+ \frac{1}{6}* 0+ \frac{1}{6}* 0 + \frac{1}{6}*0[/tex]
[tex]= \frac{4}{6} + \frac{1}{6}+ \frac{1}{6}[/tex]
[tex]= \frac{6}{6}[/tex]
[tex]= 1[/tex]
Hence, the Value of X = $1.

The increase in the price of tacos shifts the demand curve to the left, causing a decrease in the equilibrium price and quantity of hamburgers.
The accompanying supply and demand diagram is depicting the market for hamburgers in your hometown. The event that is given is that the price of tacos increases. This will cause the demand curve to shift to the left, as consumers shift from hamburgers to tacos. As the demand curve shifts to the left, the equilibrium price will decrease and the equilibrium quantity will decrease. This is because the decrease in demand will cause the quantity demanded to fall and the decrease in demand will cause the price to fall. This shift in the supply and demand curves will cause the equilibrium point to move to the left and downward. The new equilibrium price will be lower than the original equilibrium price and the quantity will also be lower.

you have 30 coins worth 2.05 dollars in dimes and nickels. whats in your wallet.
The number of dimes and nickels are equal to 11 and 19 respectively.
How to determine the number of dimes and nickels?In order to determine the number of dimes and nickels, we would assign a variables to the unknown numbers and then translate the word problem into algebraic equation as follows:
Let d represent the number of dimes.Let n represent number of nickels.Since you have a total number of 30 coins, an equation which models this situation is given by;
d + n = 30 ....equation 1.
Note: 1 nickel is equal to 0.05 dollar and 1 dime is equal to 0.1 dollar.
Additionally, the coins are worth 2.05 dollars;
0.1d + 0.05n = 2.05 ....equation 2.
Solving both equations simultaneously, we have:
0.1(30 - n) + 0.05n = 2.05
3 - 0.1n + 0.05n = 2.05
3 - 0.05n = 2.05
0.05n = 0.95
n = 0.95/0.05
n = 19 nickels.
For the number of dimes;
d = 30 - n
d = 30 - 19
d = 11 dimes.
