Bethany thinks of a number 6/13 of her number is 48 what is 1/13
The number that Bethany thinks of is 104, and 1/13 of that number is 8.
Word problemsWord problems in mathematics involve arithmetic operations and the use of variables to solve those problems. Word problems are problems we encounter in our daily life and with the use of correct mathematical interpretation, we can provide accurate solutions to them.
Let the number that Bethany thinks of be (x) for example. So, 6/13 of x is equal to 48.

In the balance sheet, mortgage notes payable are reported as both a current and a long-term liability. a current liability only. a current liability except for the reduction in principal amount. a long-term liability only.
In the balance sheet, mortgage notes payable are reported as a long-term liability only.
Mortgage notes payable represent the amount owed by a company for a mortgage loan. These loans are typically long-term obligations that are expected to be repaid over an extended period, often several years. Therefore, mortgage notes payable are classified as long-term liabilities in the balance sheet.
Current liabilities are obligations that are expected to be settled within a short period, usually one year or less. Since mortgage notes payable typically have a longer repayment term, they do not meet the criteria to be classified as current liabilities.
By reporting mortgage notes payable as a long-term liability, the balance sheet provides a clear distinction between the company's short-term and long-term obligations, helping stakeholders understand the company's financial position and obligations over different time horizons.

Use an appropriate substitution to solve the equation xy' y=-6xy and find the solution thats satisfites y(1)=-8
The particular solution that satisfies y(1) = -8 is given by:
\(\(y = \pm e^{-6x + \ln(8) + 6}\)\\\(y = \pm e^{-6x + \ln(8)}e^6\)\\\(y = \pm 8e^{-6x + 6}\)\)
To solve the equation xy' - y = -6xy using an appropriate substitution, let's make the substitution u = xy.
Taking the derivative of u with respect to x, we have:
\(\(\frac{du}{dx} = x\frac{dy}{dx} + y\)\)
Substituting this into the original equation, we get:
\(\(x\frac{dy}{dx} + y - y = -6xy\)\\\(x\frac{dy}{dx} = -6xy\)\)
Now, we can divide both sides by x and rearrange the equation:
\(\(\frac{dy}{dx} = -6y\)\)
This is a separable first-order linear ordinary differential equation. We can solve it by separating the variables and integrating.
\(\(\frac{dy}{y} = -6dx\)\)
Integrating both sides, we have:
\(\(\ln|y| = -6x + C\)\)
\(\(\ln|y| = -6x + C\)\)
Now, we can solve for y by exponentiating both sides:
\(\(|y| = e^{-6x + C}\)\)
Since we are given the initial condition y(1) = -8, we can substitute this into the equation to find the value of the constant \(C\).
When x = 1:
\((|-8| = e^{-6(1) + C}\)\\\(8 = e^{-6 + C}\)\)
Taking the natural logarithm of both sides, we get:
\(\(\ln(8) = -6 + C\)\\\(C = \ln(8) + 6\)\)
Therefore, the particular solution that satisfies y(1) = -8 is given by:
\(\(y = \pm e^{-6x + \ln(8) + 6}\)\\\(y = \pm e^{-6x + \ln(8)}e^6\)\\\(y = \pm 8e^{-6x + 6}\)\)

Step-by-step explanation:
Vincent deposit $165 at the end of each quarter at an annual
interest rate of 6% compounded quarterly. After how many years will
he has $9,000?
It will take approximately 3.96 years (or approximately 3 years and 11 months) for Vincent's savings to reach $9,000.
To solve this problem, we can use the formula for the future value of an ordinary annuity:
FV = P * [(1 + r)^n - 1] / r
Where:
FV = Future Value
P = Payment (deposit amount)
r = Interest rate per compounding period
n = Number of compounding periods
In this case, Vincent deposits $165 at the end of each quarter, so P = $165. The annual interest rate is 6%, compounded quarterly, so the interest rate per compounding period, r, would be 6% divided by 4 (since there are 4 quarters in a year), which is 0.06/4 = 0.015.
We want to find the number of years, n, it will take for Vincent's savings to reach $9,000. Let's substitute the given values into the formula and solve for n:
9,000 = 165 * [(1 + 0.015)^n - 1] / 0.015
To solve this equation, we can use algebraic techniques or a financial calculator. Solving the equation, we find that n is approximately 15.83.
Since n represents the number of quarters, we need to convert it to years by dividing it by 4 (since there are 4 quarters in a year):
n (in years) = 15.83 / 4 ≈ 3.96
Therefore, it will take approximately 3.96 years (or approximately 3 years and 11 months) for Vincent's savings to reach $9,000.

+z)/[(z−1/2+j1/2)(z−1/2−j1/2)] with ROC∣z∣>0.707, find x(n) in a form that contains no complex numbers.
The x(n) in a form that contains no complex numbers is: x(n) = (-1/4)(1/\(2)^n\)u(n) cos(π/4 n) + (3/4)(1/2\()^n\)u(n) sin(π/4 n)
To find x(n) in a form that contains no complex numbers, we can use the inverse Z-transform.
The expression X(z) = \((z^2\) + z) / [(z - 1/2 + j1/2)(z - 1/2 - j1/2)], we can rewrite it as:
X(z) = A / (z - 1/2 + j1/2) + B / (z - 1/2 - j1/2)
where A and B are constants to be determined. To find these constants, we can use partial fraction decomposition.
We multiply both sides of the equation by the denominators:
(z - 1/2 + j1/2)(z - 1/2 - j1/2) * X(z) = A + B
Expanding the left side and simplifying, we get:
\(z^2\) + z = A(z - 1/2 - j1/2) + B(z - 1/2 + j1/2)
Equating the coefficients of like powers of z on both sides, we have:
For \(z^2\) term: 1 = A + B
For \(z^1\) term: 1 = -A - B
For \(z^0\) term: 0 = -(1/2)A + (1/2)B
Solving this system of equations, we find A = -1/2 and B = 3/2.
Now, we can rewrite X(z) as:
X(z) = (-1/2) / (z - 1/2 + j1/2) + (3/2) / (z - 1/2 - j1/2)
Next, we can use the Z-transform property that relates x(n) to X(z) to find x(n):
x(n) = \(Z^-1{X(z)}\)
Using the inverse Z-transform tables or formulas, we can find the inverse Z-transform of each term. The inverse Z-transform of 1 / (z - a) is a^n u(n), where a is a constant and u(n) is the unit step function.
Therefore, applying the inverse Z-transform to each term, we have:
x(n) = \((-1/2)(1/2)^n u(n) e^(jπ/4 n) + (3/2)(1/2)^n u(n) e^(-jπ/4 n)\)
Simplifying further, we get:
x(n) =\((-1/4)(1/2)^n u(n) e^(jπ/4 n) + (3/4)(1/2)^n u(n) e^(-jπ/4 n)\)

the fourteen digits of an account number are to be written, one per unit square, in the string of unit squares below. the sum of any three consecutive digits is 15. what is the value of x?
The value of x is 4 which means that the first digit in the sequence is 4, the second digit is 5, the third digit is 6, and so on.
This problem is asking for the value of x in a sequence of 14 digits where the sum of any three consecutive digits is equal to 15. To solve for x, we can use the information provided and basic algebra.
Let's assign a variable to each of the 14 digits in the sequence. For example, let x be the first digit, (x + 1) be the second digit, (x + 2) be the third digit, and so on. Then, the sum of any three consecutive digits must equal 15:
x + (x + 1) + (x + 2) = 15
Expanding and solving for x, we get:
3x + 3 = 15
3x = 12
x = 4
So, the value of x is 4. This means that the first digit in the sequence is 4, the second digit is 5, the third digit is 6, and so on. By continuing this pattern, we can fill in the entire sequence of 14 digits such that the sum of any three consecutive digits is equal to 15.

The result of the evaluation and simplification of \(f(x)=5x^2+3x is f(x+h)-f(x)/h = h + 3\), which is a line with a slope of 1 and a y-intercept of 3.
The function\(f(x)=5x^2+3x\), when evaluated and simplified, is equal to \(f(x+h)-f(x)/h\). To calculate \(f(x+h)-f(x)/h\), the first step is to subtract f(x) from f(x+h).

Megan is part of a catch and release program for purple frogs. She catches 22 frogs and releases them after marking them. The next day, her team catches 198 frogs with 7 marked frogs. Estimate the total frog population to the nearest ten
Rounding to the nearest ten, the estimated total frog population is approximately 620.
The ratio of marked frogs to the total catch is:
marked frogs / total catch = 7 / 198
Now, we can set up a proportion to find the estimated total frog population:
marked frogs / total catch = 7 / 198
22 / total population = 7 / 198
To solve for the total population, we can cross-multiply:
22 * 198 = 7 * total population
4356 = 7 * total population
Divide both sides by 7:
4356 / 7 = total population

Point a has coordinate a(3, 2). the point is rotated 180° clockwise about the origin. what is the x-coordinate of point a’? ( enter one corrdinate point only )
To rotate a point 180° clockwise about the origin, we essentially need to flip the point across the x-axis and then across the y-axis. So the x-coordinate of point A' is -3.
This means that the x-coordinate of the point will become its opposite (negation) and the y-coordinate of the point will also become its opposite.
So, in this problem, we have the point A with coordinates (3, 2). To rotate this point 180° clockwise about the origin, we will negate both the x and y coordinates of the point:
The negation of 3 is -3, so the new x-coordinate of the point will be -3.
The negation of 2 is -2, so the new y-coordinate of the point will be -2.
Putting these together, we get the new coordinate of the point A' as (-3, -2).
So the x-coordinate of point A' is -3.
