Find a general solution to the given Cauchy-Euler equation for t > 0.
t^2. d^2y/dt^2 + 8t. dy/dt -18y =0
The general solution is y(t)
The general solution is y(t) = c1 t⁻⁹ + c2 t² for the Cauchy-Euler equation t² d²y/dt² + 8t dy/dt - 18y.
We can solve this second-order Cauchy-Euler equation by assuming a solution of the form:
y(t) = \(t^{r\)
We substitute this solution into the differential equation and find the characteristic equation by solving for the values of r that satisfy the equation:
t² d²y/dt² + 8t dy/dt - 18y = 0
t² [r(r-1) \(t^{(r-2)}\)] + 8t [r \(t^{(r-1)}\)] - 18\(t^r\) = 0
r(r-1) + 8r - 18 = 0
r² + 7r - 18 = 0
(r + 9)(r - 2) = 0
So the roots are r = -9 and r = 2. Therefore, the general solution is a linear combination of the two independent solutions:
y(t) = c1 \(t^{(-9)\) + c2 t²
where c1 and c2 are constants to be determined by the initial or boundary conditions of the problem.

how to find sample size with margin of error on ti 84
The appropriate sample size formula on the TI-84 calculator, you can determine the sample size needed to achieve your desired margin of error for estimating population parameters.
To find the sample size with a desired margin of error on a TI-84 calculator, you can use the following steps:
1. Determine the desired margin of error: Decide on the maximum allowable difference between the sample estimate and the true population parameter. For example, if you want a margin of error of ±2%, your desired margin of error would be 0.02.
2. Determine the confidence level: Choose the desired level of confidence for your interval estimate. Common choices include 90%, 95%, or 99%.
Convert the confidence level to a corresponding z-score. For instance, a 95% confidence level corresponds to a z-score of approximately 1.96.
3. Calculate the estimated standard deviation: If you have an estimate of the population standard deviation, use that value. Otherwise, you can use a conservative estimate or a pilot study's standard deviation as a substitute.
4. Use the formula: The sample size formula for estimating a population mean is n = (z^2 * s^2) / E^2, where n represents the sample size, z is the z-score, s is the estimated standard deviation, and E is the desired margin of error.
5. Plug in the values: Input the values of the z-score, estimated standard deviation, and desired margin of error into the formula. Use parentheses and proper order of operations to ensure accurate calculations.
6. Calculate the sample size: Perform the calculations using the calculator, making sure to include the appropriate multiplication and division symbols. The result will be the recommended sample size to achieve the desired margin of error.

A side length of a regular nonagon is an integer. The perimeter of the nonagon is 80
when rounded to the nearest ten. Determine the integer side length.
If the side length is n, then the perimeter is 9n. The closest multiple of 9 to 80 is 81, so n = 9.
Step-by-step explanation:
A nonagon is a shape with 9 sides. A regular shape means that all angles and sides of the shape is equal. That means let call the side of the nonagon, n. That means the perimeter which is 80, which means all side, n will add up.
\(n + n + n + n + n + n + n + n + n = 80\)
or
\(9n = 80\)
Solve for n
\(n = \frac{80}{9} \)
This rounded would make our interger side, 9
The ________________ is the horizontal number line on the coordinate grid.
Answer:
x-axis
Step-by-step explanation:
The horizontal number line is called the x-axis. The vertical number line is called the y-axis. The point where the x- and y-axes meet is the origin.
Hope this helps! <3
The x-axis is the horizontal number line on the coordinate grid.
It is one of the two axes that form the Cartesian coordinate system, used to locate points in a two-dimensional plane. The x-axis runs horizontally from left to right, intersecting with the vertical y-axis at the origin (0,0). It acts as a reference line, assigning numerical values to the horizontal position of points on the grid.
The x-axis allows us to specify the x-coordinate of a point, which represents its horizontal distance from the origin. Positive values are to the right of the origin, while negative values are to the left. By combining the x-axis with the y-axis, we can precisely define the position of any point in the coordinate plane.

real numbers x and y are chosen independently and uniformly at random from the interval [0,1]. which of the following numbers is closest to the probability that x,y, and 1 are the side lengths of an obtuse triangle?
The answer is (D) 0.25. To form an obtuse triangle using side lengths x, y, and 1, the largest side must be less than the sum of the other two sides.
Without loss of generality, assume that x ≤ y. Then, the largest side is 1, and the triangle is obtuse if and only if x² + y² < 1². This defines a circle with radius 1 centered at the origin in the xy-plane.
The region of the unit square [0,1] x [0,1] where x² + y² < 1² corresponds to the area inside this circle. This area can be computed as π/4.
Therefore, the probability that x, y, and 1 are the side lengths of an obtuse triangle is the ratio of the area of the circle to the area of the unit square, which is π/4 / 1 = 0.7854. The answer closest to this value is 0.25.

Dante drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 10 hours. When Dante drove home, there was no traffic and the trip only took 7 hours. If his average rate was 18 miles per hour faster on the trip home, how far away does Dante live from the mountains?Do not do any rounding.
You know that:
- Last weekend his trip took 10 hours when he drove to the mountains.
- When he drove home, the trip took 7 hours.
- His average rate was 18 miles per hour faster on the trip home.
By definition, the distance can be calculated with this formula:
\(d=rt\)Where "d" is distance, "r" is rate, and "t" is time.
Then, you can set up the following equation to represent his trip to the mountains ("d" is in miles):
\(d=10r\)And you can set up the following equation to represent his trip home ("d" is in miles):
\(d=7(r+18)\)To find the value of "r", you need to make both equations equal to each other and solve for "r". Then, you get:
\(\begin{gathered} 10r=7(r+18) \\ 10r=7r+126 \\ 10r-7r=126 \\ \\ r=\frac{126}{3} \\ \\ r=42 \end{gathered}\)Knowing the value of "r", you can substitute it into the second equation:
\(\begin{gathered} d=7\mleft(r+18\mright) \\ d=(7)\mleft(42+18\mright) \end{gathered}\)Finally, evaluating, you get (Remember that "d" is in miles)
\(\begin{gathered} d=(7)(60) \\ d=420 \end{gathered}\)Therefore, the answer is:

you flip a coin twice. what is the probability that you observe tails on the first flip and heads on the second flip? (write as a decimal)
.25
Step-by-step explanation:
probability can be difficult to answer because of the overlap with possibility and chances etc etc... lower level classes will typically take the answer .25 while higher-level classes may prefer the answer .5
Therefore, the probability of observing tails on the first flip and heads on the second flip is 0.25 or 1/4.
When flipping a fair coin twice, the outcome of each flip is independent of the other. The probability of observing tails on the first flip is 1/2 (0.5), and the probability of observing heads on the second flip is also 1/2 (0.5).
To find the probability of both events occurring, we multiply the probabilities together:
P(tails on first flip and heads on second flip) = P(tails on first flip) * P(heads on second flip) = 0.5 * 0.5 = 0.25.
