Answer:
it equals -21 so no
Step-by-step explanation:
happy valentines!
Answer:
No, It does not.
Step-by-step explanation:
(3,4) means (x,y). When you insert 3 to x and 4 to y, You get this:
5(3)-9(4)=32
If you multiply 5 and 3, You get 15.
15-9(4)=32
If you multiply 9 and 4, you get 36.
15-36=32
If you subtract 15-36, you get -21.
This is why the answer is no because -21 does not equal 32
-21 ≠ 32
Hope this helps! :)
Find the general solution for the following differential equation using the method of undetermined coefficients d²y/dx - 36 y = cosh3x.
The general solution for the given differential equation is the sum of the complementary function and the particular solution:
\(y = y_h + y_p\\\\= C_1e^{6x} + C_2e^{-6x} + (-1/70)e^{3x} + (-1/70)e^{-3x}\)
where C₁ and C₂ are arbitrary constants determined by the initial or boundary conditions of the problem.
We are given the differential equation: d²y/dx - 36y = cosh(3x).
In this case, the homogeneous equation is d²y/dx - 36y = 0.
The characteristic equation associated with the homogeneous equation is obtained by replacing the derivatives with their corresponding algebraic expressions. In our case, we have r² - 36 = 0. Solving this quadratic equation, we find the roots to be r = ±6.
Since the roots are distinct and real, the general solution for the homogeneous equation is given by:
\(y_h = C_1e^{6x} + C_2e^{-6x}\)
where C₁ and C₂ are arbitrary constants determined by the initial or boundary conditions of the problem.
The term cosh(3x) can be written as a linear combination of exponential functions using the identities:
\(cosh(ax) = (e^{ax} + e^{-ax})/2, \\\\sinh(ax) = (e^{ax} - e^{-ax})/2.\)
Therefore, \(cosh(3x) = (e^{3x} + e^{-3x})/2.\)
Now, we assume the particular solution has the form:
\(y_p = A_1e^{3x} + A_2e^{-3x}\)
where A₁ and A₂ are undetermined coefficients.
Substituting these derivatives into the original differential equation, we get:
\((9A_1e^{3x} + 9A_2e^{-3x}) - 36(A_1e^{3x} + A_2e^{-3x}) = (e^{3x} + e^{-3x})/2.\)
To satisfy this equation, the coefficients of the exponential terms on both sides must be equal. Therefore, we have the following system of equations:
9A₁ - 36A₁ = 1/2,
9A₂ - 36A₂ = 1/2.
Solving these equations, we find A₁ = -1/70 and A₂ = -1/70.
Thus, the particular solution is:
\(y_p = (-1/70)e^{3x} + (-1/70)e^{-3x}\)
Finally, the general solution for the given differential equation is the sum of the complementary function and the particular solution:
\(y = y_h + y_p\\\\= C_1e^{6x} + C_2e^{-6x} + (-1/70)e^{3x} + (-1/70)e^{-3x}\)
where C₁ and C₂ are arbitrary constants determined by the initial or boundary conditions of the problem.

assume the population was the houston rockets. find 1) the population mean 2) the population standard deviation 3) the weight that is 1.5 standard deviation below the mean.
Weight that is 1.5 standard deviation below the mean: To find the weight that is 1.5 standard deviation below the mean, subtract 1.5 times the population standard deviation from the population mean.
The population mean, population standard deviation, and weight that is 1.5 standard deviation below the mean for the Houston Rockets can be calculated using the following steps:
1) Population mean: The population mean is the average of all the values in the population. To calculate the population mean, add up all the values in the population and divide by the total number of values. For example, if the weights of the Houston Rockets players are 200, 210, 220, 230, and 240 pounds, the population mean would be (200 + 210 + 220 + 230 + 240) / 5 = 220 pounds.
2) Population standard deviation: The population standard deviation is a measure of how spread out the values in the population are. To calculate the population standard deviation, first calculate the deviation of each value from the population mean, square each deviation, add up all the squared deviations, divide by the total number of values, and take the square root of the result. For example, if the weights of the Houston Rockets players are 200, 210, 220, 230, and 240 pounds, the population standard deviation would be √[((200 - 220)^2 + (210 - 220)^2 + (220 - 220)^2 + (230 - 220)^2 + (240 - 220)^2) / 5] = 14.14 pounds.
3) Weight that is 1.5 standard deviation below the mean: To find the weight that is 1.5 standard deviation below the mean, subtract 1.5 times the population standard deviation from the population mean. For example, if the population mean is 220 pounds and the population standard deviation is 14.14 pounds, the weight that is 1.5 standard deviation below the mean would be 220 - (1.5 * 14.14) = 199.79 pounds.

If a person selects one of each item, how many different meals can be ordered?
different meals
There are 84,672 different meals that can be ordered by selecting one item from each category.
To determine the number of different meals that can be ordered by selecting one item from each category, we need to multiply the number of choices in each category together.
In this case, the number of choices for each category are as follows:
Drinks: 12 choices
Appetizers: 7 choices
Main Entrees: 8 choices
Side Dishes: 14 choices
Desserts: 9 choices
To calculate the total number of different meals, we multiply these numbers together:
Number of different meals = Number of choices in Drink category × Number of choices in Appetizer category × Number of choices in Main Entree category × Number of choices in Side Dishes category × Number of choices in Dessert category
Number of different meals = 12 × 7 × 8 × 14 × 9
Calculating this expression gives us:
Number of different meals = 84,672
Therefore, there are 84,672 different meals that can be ordered by selecting one item from each category.

Write the ordered pair for each point. Use the grid
The ordered pair for each point using the grid is (4,3). An ordered pair is a set of two numbers that represent a point in the coordinate plane.
In general, the first number represents the horizontal or x-coordinate, and the second number represents the vertical or y-coordinate. These coordinates are usually represented in brackets and separated by a comma. For example, (2,3) is an ordered pair whose x-coordinate is 2, and whose y-coordinate is 3. What is a grid? A grid is a set of horizontal and vertical lines that are used to form boxes, creating a pattern of squares. In mathematics, we use grids to represent the coordinate plane. The x-axis, which runs horizontally, is marked with positive numbers to the right and negative numbers to the left of the origin. The y-axis, which runs vertically, is marked with positive numbers above and negative numbers below the origin. How to write the ordered pair for each point? To write the ordered pair for each point using the grid, we need to follow these steps: Step 1: Locate the point on the grid. Let's say we have a point that lies in the third row (y-coordinate) and the fourth column (x-coordinate). We would locate this point by counting three rows down and four columns to the right. This point is shown below. Step 2: Write the ordered pair for the point. In this case, the x-coordinate is 4, and the y-coordinate is 3. We write these coordinates in brackets, separated by a comma. Therefore, the ordered pair for this point is (4, 3). The ordered pair for each point using the grid is (4,3). The first number in the ordered pair is the x-coordinate, and the second number is the y-coordinate.

if a 10,000 kg ufo made of antimatter crashed with a 40,000 kg plane made of matter, calculate the energy of the resulting explosion.
To calculate the energy of the resulting explosion when a 10,000 kg UFO made of antimatter crashes with a 40,000 kg plane made of matter, we can use Einstein's famous equation, E=mc², which relates energy (E) to mass (m) and the speed of light (c).
In this case, we'll need to calculate the total mass of matter and antimatter involved in the collision and then use the equation to find the energy released. The equation E=mc² states that energy is equal to the mass multiplied by the square of the speed of light (c). In this scenario, we have a collision between a UFO made of antimatter and a plane made of matter. Antimatter and matter annihilate each other when they come into contact, resulting in a release of energy.
To calculate the energy of the resulting explosion, we need to determine the total mass involved in the collision. The total mass can be calculated by adding the masses of the UFO and the plane together. In this case, the UFO has a mass of 10,000 kg and the plane has a mass of 40,000 kg, so the total mass is 50,000 kg.
Next, we can use the equation E=mc² to calculate the energy. The speed of light (c) is a constant value, approximately 3 x 10^8 meters per second. Plugging in the values, we have E = (50,000 kg) x (3 x 10^8 m/s)². Simplifying the equation, we have E = 50,000 kg x 9 x 10^16 m²/s².Multiplying the numbers, we get E = 4.5 x 10^21 joules. Therefore, the energy of the resulting explosion when the UFO and plane collide is approximately 4.5 x 10^21 joules.

In a 2-sample z-test for two proportions, you find the following: X1 = 24 n1 = 200 X2 = 17 my = 150 You decide
to run a test for which the alternative hypothesis is Hj: p1 > p2- Find the appropriate test statistic for the
test. Enter the test statistic - round to 4 decimal places. Z =
The appropriate test statistic for this test is approximately 0.2103 (rounded to 4 decimal places).
To find the appropriate test statistic for a 2-sample z-test for two proportions, we need to calculate the standard error and then use it to compute the z-score. The formula for the standard error is:
SE = sqrt[(p1 * (1 - p1) / n1) + (p2 * (1 - p2) / n2)]
Where p1 and p2 are the sample proportions, and n1 and n2 are the sample sizes.
In this case, we have the following values:
X1 = 24 (number of successes in sample 1)
n1 = 200 (sample size 1)
X2 = 17 (number of successes in sample 2)
n2 = 150 (sample size 2)
To calculate the sample proportions, we divide the number of successes by the respective sample sizes:
p1 = X1 / n1 = 24 / 200 = 0.12
p2 = X2 / n2 = 17 / 150 = 0.1133
Now, we can plug these values into the formula to calculate the standard error:
SE = sqrt[(0.12 * (1 - 0.12) / 200) + (0.1133 * (1 - 0.1133) / 150)]
SE ≈ 0.0319
Finally, the test statistic (z-score) is calculated by subtracting the two sample proportions and dividing by the standard error:
Z = (p1 - p2) / SE
Z = (0.12 - 0.1133) / 0.0319
Z ≈ 0.2103
Therefore, the appropriate test statistic for this test is approximately 0.2103 (rounded to 4 decimal places).

If 4 less than a certain integer is multiplied by 5 more than the integer, the product is 3 less than the square of the integer. The integer is 8
What is the value of the integer when 4 less than it is multiplied by 5 more than it, resulting in a product that is 3 less than the square of the integer?To find the value of the integer, let's call it 'x.' According to the given information, when 4 less than 'x' is multiplied by 5 more than 'x,' the resulting product is 3 less than the square of 'x.' Mathematically, we can represent this as (x - 4) * (x + 5) = x^2 - 3.
Simplifying the equation, we expand the product on the left side: x^2 + 5x - 4x - 20 = x^2 - 3. By combining like terms, the equation becomes x^2 + x - 20 = x^2 - 3.
Next, we eliminate the x^2 terms by subtracting x^2 from both sides of the equation: x^2 - x^2 + x - 20 = x^2 - x^2 - 3. This simplifies to x - 20 = -3.
To isolate the 'x' term, we add 20 to both sides: x - 20 + 20 = -3 + 20. This yields x = 17.
Therefore, the value of the integer 'x' is 17.

A-REI.3 Suppose a friend tells you she wants to buy a bicycle with a price of $3749.99, and you’d like to know the bicycle’s total price (the price after taxes) so that you can compare prices at in other counties.. Find the total price, p, of the bicycle if your friend bought the bicycle in a location where the rate is r. Assume r is the rate in decimal form.
Write the equation for the situation then solve it for r.
The total price of the bicycle in Pierce county is $4136.24
An equation shows the relationship between two or more variables and numbers.
Let P represent the total price after taxes. The tax rate is 10.3% and the price of the bicycle is $3749.99. Hence:
Tax = 10.3% of $3749.99 = 0.103 * 3749.99 = $386.25
The total price (P) is:
P = $3749.99 + Tax = $3749.99 + $386.25
P = $4136.24
Therefore, the total price of the bicycle in Pierce county is $4136.24
