Answer:
there is a 13 degree difference from DBC and DAC
with that you divide 1540 by 13 as you get that 118.461 feet
that means that there is a 118.461 difference from B to C and A to B
so the answer is either 1658.461ft or 1421.539ft I am not sure if that is correct or not but best of luck mate
Can you plz help me by solving the equation and showing how you got the answer

Write the form of the partial fraction decomposition of the rational expression.
11x - 10/ (x-6)(x+7)
Answer:
x+7x2+3x+2=6x+1+−5x+2
Step-by-step explanation:
Simplify the expression: x+7x2+3x+2=x+7(x+1)(x+2)
The form of the partial fraction decomposition is
x+7(x+1)(x+2)=Ax+1+Bx+2
Write the right-hand side as a single fraction:
x+7(x+1)(x+2)=(x+1)B+(x+2)A(x+1)(x+2)
The denominators are equal, so we require the equality of the numerators:
x+7=(x+1)B+(x+2)A
Expand the right-hand side:
x+7=xA+xB+2A+B
Collect up the like terms:
x+7=x(A+B)+2A+B
The coefficients near the like terms should be equal, so the following system is obtained:
{A+B=12A+B=7
Solving it (for steps, see system of equations calculator), we get that A=6, B=−5
Therefore,
x+7(x+1)(x+2)=6x+1+−5x+2
Answer: x+7x2+3x+2=6x+1+−5x+2

Hannah signs on a $148,500 mortgage at a 4.5% annual interest rate for 20 years. This results in a monthly payment is
$938.48. If only the minimum payment is made in month one, how much of the first payment goes toward reducing her
balance?
First let's find the amount of interest she paid in month 1, then find the amount toward reducing the balance.
Round to the nearest cent.
Answer:
Interest in one month= 556.88
Her balance is reduced by= 381.6

Let f(x) = cxe−x2 if x ≥ 0 and f(x) = 0 if x < 0.
(a) For what value of c is f a probability density function?
(b) For that value of c, find P(1 < X < 3).
(a) If f(x) is to be a proper density function, then its integral over the given support must evaulate to 1:
[tex]\displaystyle\int_{-\infty}^\infty f(x)\,\mathrm dx = \int_0^\infty cxe^{-x^2}\,\mathrm dx=1[/tex]
For the integral, substitute u = x ² and du = 2x dx. Then as x → 0, u → 0; as x → ∞, u → ∞:
[tex]\displaystyle\frac12\int_0^\infty ce^{-u}\,\mathrm du=\frac c2\left(\lim_{u\to\infty}(-e^{-u})-(-1)\right)=1[/tex]
which reduces to
c / 2 (0 + 1) = 1 → c = 2
(b) Find the probability P(1 < X < 3) by integrating the density function over [1, 3] (I'll omit the steps because it's the same process as in (a)):
[tex]\displaystyle\int_1^3 2xe^{-x^2}\,\mathrm dx = \boxed{\frac{e^8-1}{e^9}} \approx 0.3678[/tex]

A certain type of legal proceeding has three possible outcomes: in favor of party A, in favor of party B, or not in favor of either party. The outcomes are expected to be 40 percent, 20 percent, and 40 percent, respectively. A random sample of 40 cases is selected from a certain judge to investigate whether the judgeâs outcomes are consistent with the expected outcomes. A chi-square goodness-of-fit test is conducted, and the value of the chi-square test statistic is Ï2=9.19 with a corresponding pâvalue of 0.01. Assuming the conditions for inference were met, which of the following is the correct interpretation of the pâvalue?
a. There is a 1 percent chance that the company's claim is correct.
b. If the null hypothesis is true, there is a 1 percent chance that the company's claim is correct.
c. If the null hypothesis is true, there is a 1 percent chance of obtaining a chi-square value of 9.19.
d. If the null hypothesis is true, there is a 1 percent chance of obtaining a chi-square value of at least 9.19.
e. There is a 1 percent chance of obtaining a chi-square value of at least 9.19.
The basically it tells us the chances of the claim being true
If we assume the null hypothesis is correct.
What is the method of chi-square test?The Chi-Square Test of Independence determines whether there is an association between categorical variables.
We have given that,
The outcomes are expected to be 40 percent, 20 percent, and 40 percent, respectively.
If the null hypothesis is true, there is a 1 percent chance that the company’s claim is correct.
The p-value tells us the likeliness of our data occurring under the null hypothesis.
Therefore ,basically it tells us the chances of the claim being true
If we assume the null hypothesis is correct.

The ratio of the wavelength of the red note and blue note is 2 : 1.
What is wavelength?Wavelength is the distance between two consecutive crest and troughs.
Mathematically, we can write wavelength as -
λ = c/ν
where -
λ : wavelength
ν : frequency
Given are the two notes as shown in the image.
For the red note, the distance between the consecutive crests is twice to that of the distance between the consecutive crests in case of blue note. We can write the ratio of the wavelengths as -
λ(R)/λ(B) = 2/1
Therefore, the ratio of the wavelength of the red note and blue note is 2 : 1.
