To measure the distance across a wide river surveyors use a technique of measuring angles to a fixed point on the other side of the river. In the diagram below, a survey starts a point A and find m
Answer:
DC = 1332.95 feet
Step-by-step explanation:
From the figure attached,
Let the measure of DC = h ft
And measure of side BC = a ft
By applying tangent ratio in ΔBCD,
tan(56°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{DC}{BC}[/tex]
= [tex]\frac{h}{a}[/tex]
h = a[tan(56°)] --------(1)
By applying tangent rule in ΔACD,
tan(22°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(22°) = [tex]\frac{DC}{BC+AC}[/tex]
= [tex]\frac{h}{a+2400}[/tex]
h = (a + 2400)tan(22°) ------- (2)
Equating the values of h from equations (1) and (2),
a[tan(56°)] = (a + 2400)tan(22°)
a[tan(56°) - tan(22°)] = 2400[tan(22°)]
1.0785a = 968.6629
a = 899.085 ft
From equation (1),
h = 899.085[tan(56°)]
h = 1332.948
h ≈ 1332.95 ft
Consider the function shown below.
g(x) = 2^x
If the function g is horizontally compressed by a factor of 1/2 and reflected across the x-axis to obtain function f, which of the following graphs matches the above transformation?
The graph of the transformation by of horizontally compressing g(x) by a factor of 1/2 and then reflecting across the x-axis is graph Y
How to determine the graph?The function is given as:
[tex]g(x) = 2^x[/tex]
When compressed horizontally by a factor of 1/2, the transformation rule is:
g'(x) = g(2x)
So, we have:
[tex]g(2x) = 2^{2x}[/tex]
[tex]g(2x) = 4^x[/tex]
When reflected across the x-axis, the transformation rule is:
[tex](x,y) \to (x,-y)[/tex]
So, we have:
[tex]f(x) = -4^x[/tex]
The graph represented by this is graph Y.
Hence, the graph of the transformation is graph Y

Solve the system of equations x' 2x – 3y + 2 sin(2t) y' = x – 2y — 2 cos(2t)
Upon solving the given system of equations:
[tex]x(t) = (c_1 + e^{-t}) + (3/2) * (c_2 + e^{-t}) * cos(2t) + (1/2) * (c_1 + e^{-t}) * sin(2t),\\y(t) = (c_1 + e^{-t}) + (3/2) * (c_2 + e^{-t}) * sin(2t) - (1/4) * (c_1 + e^{-t}) * cos(2t)[/tex]
To solve the system of equations:
x' = 2x - 3y + 2sin(2t)
y' = x - 2y - 2cos(2t)
We can use the method of undetermined coefficients to find the particular solution. Assuming the particular solution takes the form:
[tex]x_p(t) = A sin(2t) + B cos(2t)\\y_p(t) = C sin(2t) + D cos(2t)[/tex]
Substituting these expressions into the original equations, we get:
2(A sin(2t) + B cos(2t)) - 3(C sin(2t) + D cos(2t)) + 2sin(2t) = 2sin(2t)
(A sin(2t) + B cos(2t)) - 2(C sin(2t) + D cos(2t)) - 2cos(2t) = cos(2t)
(2A - 3C + 2)sin(2t) + (2B - 3D)cos(2t) = 2sin(2t)
(A - 2C)sin(2t) + (B - 2D - 2)cos(2t) = cos(2t)
By comparing the coefficients of sine and cosine on both sides, we can equate them separately:
2A - 3C + 2 = 2
2B - 3D = 0
A - 2C = 0
B - 2D - 2 = 1
Solving these equations, we find:
A = 1
B = 3/2
C = 1/2
D = -1/4
So the particular solution is:
[tex]x_p(t)[/tex] = sin(2t) + (3/2)cos(2t)
[tex]y_p(t)[/tex] = (1/2)sin(2t) - (1/4)cos(2t)
To find the complementary solution, we solve the homogeneous system:
x' = 2x - 3y
y' = x - 2y
We can rewrite this system as a matrix equation:
X' = AX
where [tex]X = [x, y]^T[/tex] and
[tex]A = \left[\begin{array}{ccc}2&-3\\1&-2\end{array}\right][/tex]
The characteristic equation is:
det(A - λI) = 0, where I is the identity matrix. Solving this equation, we find the eigenvalues:
[tex]\lambda_1 = -1\\\lambda_2 = -1[/tex]
For each eigenvalue, we solve the corresponding eigenvector equation:
(A - λI)V = 0
For [tex]\lambda_1 = -1[/tex], we have:
[tex]\left[\begin{array}{ccc}3&-3\\1&-1\end{array}\right] * V_1 = 0[/tex]
Solving this system, we find the eigenvector:
[tex]V_1 = [1\ \ 1][/tex]
For [tex]\lambda_2 = -1[/tex], we have:
[tex]\left[\begin{array}{ccc}3&-3\\1&-1\end{array}\right] * V_2= 0[/tex]
Solving this system, we find the eigenvector:
[tex]V_2 = [3\ \ 1][/tex]
So the complementary solution is:
[tex]x_c(t) = c_1 * e^{-t} * [1\ \ 1]^T + c_2 * e^{-t} * [3\ \ 1]^T\\y_c(t) = c_1 * e^{-t} * [1\ \1]^T + c_2 * e^{-t} * [3\ \ 1]^T[/tex]
where
[tex]c_1\ and\ c_2[/tex] are arbitrary constants.
The general solution is the sum of the particular and complementary solutions:
[tex]x(t) = x_p(t) + x_c(t)\\y(t) = y_p(t) + y_c(t)[/tex]
Simplifying and combining terms, we get:
[tex]x(t) = (c_1 + e^{-t}) + (3/2) * (c_2 + e^{-t}) * cos(2t) + (1/2) * (c_1 + e^{-t}) * sin(2t)\\y(t) = (c_1 + e^{-t}) + (3/2) * (c_2 + e^{-t}) * sin(2t) - (1/4) * (c_1 + e^{-t}) * cos(2t)[/tex]

The approximate values of the solution to the given initial value problem at the four time steps t = 0.1, 0.2, 0.3 and 0.4 using the modified Euler formula with step sizes h = 0.05 and h = 0.001 are as follows:

The non-autonomous ordinary differential equation is given as:
dy/dt = f(t,y)......(1)
where f is a continuous function and is defined for all values of t and y. The numerical methods for non-autonomous ODEs are described below:
Modified Euler Formula (Improved Euler Method)This method is based on the same idea as Euler's method, but the derivative is evaluated at the midpoint of the interval instead of the initial point. Consider the initial value problem (IVP) dy/dt = f(t,y), y(to) = yo, and suppose that we want to approximate the solution at tn+1 = tn + h. Then, using the improved Euler's formula, we obtain the following approximation:
Yn+1 = yn + hF(tn + h/2, yn + hF(tn,yn)/2)......(2)
Using h = 0.05
Substituting h = 0.05 in equation (2), we get
Y1 = Y0 + 0.05(F(0.025,Y0+F(0,Y0)/2))
Y2 = Y1 + 0.05(F(0.075,Y1+F(0.05,Y1)/2))
Y3 = Y2 + 0.05(F(0.125,Y2+F(0.1,Y2)/2))
Y4 = Y3 + 0.05(F(0.175,Y3+F(0.15,Y3)/2))
Using h = 0.001
Substituting h = 0.001 in equation (2), we get
Y1 = Y0 + 0.001(F(0.0005,Y0+F(0,Y0)/2))
Y2 = Y1 + 0.001(F(0.0015,Y1+F(0.001,Y1)/2))
Y3 = Y2 + 0.001(F(0.0025,Y2+F(0.002,Y2)/2))
Y4 = Y3 + 0.001(F(0.0035,Y3+F(0.003,Y3)/2))
For the given IVP, f(t,y) = 2t + ety, y(0) = 1
So, substituting f(t,y) in equation (1), we get
dy/dt = 2t + ety.....(3)
Using the modified Euler formula (equation 2), we get
Using h = 0.05
Y1 = 1 + 0.05(2(0.025) + e(0.025)Y0) = 1.12116266
Y2 = 1.12116266 + 0.05(2(0.075) + e(0.075)Y1) = 1.25755476
Y3 = 1.25755476 + 0.05(2(0.125) + e(0.125)Y2) = 1.41728420
Y4 = 1.41728420 + 0.05(2(0.175) + e(0.175)Y3) = 1.59967883
Using h = 0.001
Y1 = 1 + 0.001(2(0.0005) + e(0.0005)Y0) = 1.00372378
Y2 = 1.00372378 + 0.001(2(0.0015) + e(0.0015)Y1) = 1.00745820
Y3 = 1.00745820 + 0.001(2(0.0025) + e(0.0025)Y2) = 1.01119282

Caitlyn uses 47-centstamps and 8.cent stamps to mail a gift card to a friend. If the postage is $2.99, how many of each stamp did Caitlyn use?
Let the number of 47-cent stamps be x, and the number of 8-cent stamps be y. So, the cost of x 47-cent stamps will be $0.47x.The cost of y 8-cent stamps will be $0.08y.Therefore, $2.99 = $0.47x + $0.08y Multiply the entire equation by 100 to eliminate decimals. $299 = 47x + 8yEquation 1.47x + 8y = 299There are a couple of ways to solve the system of equations.
One method is substitution. We can rearrange equation 1 to solve for x:47x = 299 - 8y x = (299 - 8y)/47Substitute this expression for x into the first equation: 0.47(299 - 8y)/47 + 0.08y = 2.99 Simplifying the equation, we get: 299 - 8y + 4.76y = 299y = 299/0.76y = 393.4Hence, we cannot have fractional values of y; it must be a whole number, so Caitlyn can use 32 47-cent stamps and 15 8-cent stamps to mail a gift card to a friend.

You want to save $1,200 per quarter for 15 years towards the purchase of a trailer. You feel that you can earn 3.12% compounded quarterly for this period of time. If your first deposit is in 3 months, what is the most expensive trailer that you can purchase?
The most expensive trailer can be purchased for $39,505.41. To determine the most expensive trailer that can be purchased at an interest rate of 3.12% compounded quarterly, we calculate the future value of the savings.
The formula for compound interest is given by the equation:
A = [tex]P(1 + r/n)^(nt)[/tex]
Where:
A is the future value of the savings,
P is the quarterly deposit amount ($1,200),
r is the interest rate per compounding period (3.12%),
n is the number of compounding periods per year (quarterly, so n = 4),
and t is the number of years (15).
Plugging the values into the formula, we have:
A =[tex]1200(1 + 0.0312/4)^(4*15)[/tex]
Calculating this expression, we find the future value of the savings after 15 years to be approximately $39,505.41.
Therefore, the most expensive trailer that can be purchased is $39,505.41 or less, as that is the maximum amount that will be saved over the 15-year period.

What is the value of 4/15 ➗ 2/3?
Answer:
2/5, option 4.
Step-by-step explanation:
When you are dividing 2 fractions, the first fraction stays the same, and the 2nd fraction becomes the reciprocal, and the division sign becomes a multiplication sign.
The reciprocal of 2/3 is 3/2.
Now you need to change the division sign to a multiplication sign.
The equation will now become 4/15 x 3/2.
4 times 3 is 12, and 15 times 2 is 30.
12/30 isn't an option, so you will need to simplify.
Find a common factor, then divide.
6 is a common factor, so you divide both 12 and 30 by 6, to get 2 and 5.

The time series component that exhibits a repeating pattern over successive periods, often one-year intervals is called
A. a cyclical component
B. a trend component.
C. seasonal component.
D. irregular component.
The time series component that exhibits a repeating pattern over successive periods, often one-year intervals, is called the seasonal component. It represents the regular and predictable variations in the data that occur due to seasonal factors, such as weather patterns, holidays, or annual events.
The seasonal component typically follows a consistent pattern, where the values tend to rise and fall in a similar manner within each season. For example, retail sales may experience higher values during the holiday season each year and lower values during other times.
Identifying and analyzing the seasonal component is crucial in many fields, including economics, finance, marketing, and forecasting. By understanding and accounting for the seasonal patterns, analysts and decision-makers can make more accurate predictions, adjust for seasonality in data, and develop strategies to optimize operations or sales during specific periods.
Methods such as seasonal decomposition or seasonal adjustment techniques are used to separate the seasonal component from other components, such as trend and irregular fluctuations, in order to better understand the underlying patterns and make informed decisions based on the data.

Why is it important to remember the definitions of binomial, continuous, discrete, interval, nominal, ordinal, and ratio variables?
It is important to remember the definitions of binomial, continuous, discrete, interval, nominal, ordinal, and ratio variables because these are different types of data which need different methods of analysis.
Nominal variables are variables used for identification or categorization. Nominal data cannot be ranked, ordered, or compared. The gender, ethnicity, religion, and hair color of an individual are all examples of nominal variables.
Ordinal variables are variables that can be ranked or ordered, but the difference between each point on the scale is not constant. For example, we could use an ordinal variable to describe the class ranks of students: 1st, 2nd, 3rd, and so on. While there is a clear order to the data, the difference between each rank is not necessarily the same.
Interval variables have equal distances between each value, and they also have a true zero point. For example, a temperature measurement is an interval variable because the difference between 20 degrees Celsius and 30 degrees Celsius is the same as the difference between 30 degrees Celsius and 40 degrees Celsius.
Ratio variables have equal intervals between each value and have a true zero point. For example, weight is a ratio variable because a weight of zero means that there is no weight.

When we rolled a fair, 6-sided die 1000 times. out of 1,000 rolls, the actual number of even rolls may vary due to the inherent randomness of the process.
If we assume that the die is fair and unbiased, each of the six sides has an equal probability of landing face-up. Since we are interested in the number of times the die comes up even (2, 4, or 6), we need to consider that half of the possible outcomes are even numbers.
Out of the six possible outcomes (1, 2, 3, 4, 5, 6), three are even (2, 4, 6). Therefore, the probability of rolling an even number on a fair six-sided die is 3/6 or 1/2.
If we roll the die 1000 times, we can expect that the die would come up even approximately half of the time, as per the probability. Half of 1000 is 500, so we would expect the die to come up even around 500 times out of 1000 rolls.
It's important to note that this is an expected value based on probability, and in practice, the actual number of even rolls may vary due to the inherent randomness of the process.

What is front-end ratio and how do you figure it out?
Answer:
The front-end ratio is calculated by dividing an individual's anticipated monthly mortgage payment by his/her monthly gross income. The mortgage payment generally consists of principal, interest, taxes, and mortgage insurance (PITI). Lenders use the front-end ratio in conjunction with the back-end ratio to determine how much to lend.
