Answer:
D. The graph of g(x) is 8 units above the graph of f(x)
Step-by-step explanation:
Transformations
For \(a > 0\)
\(f(x+a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units left}\)
\(f(x-a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units right}\)
\(f(x)+a \implies f(x) \: \textsf{translated}\:a\:\textsf{units up}\)
\(f(x)-a \implies f(x) \: \textsf{translated}\:a\:\textsf{units down}\)
Parent function: \(f(x)=x^2\)
Translated 8 units up: \(f(x)+8=x^2+8\)
Therefore, the graph of g(x) is 8 units above the graph of f(x)
the number which best completes the sequence below is: 20 5 30 6 42 7 ?
Answers
The answer to the question is 56. The sequence appears to alternate between adding and multiplying by a certain equation number.
From 20 to 5, we multiplied by 0.25 (or divided by 4). From 5 to 30, we added 25. From 30 to 6, we multiplied by 0.2 (or divided by 5). From 6 to 42, we added 36. Therefore, to continue the pattern, we need to multiply 7 by a certain number and then add another number. It turns out that if we multiply 7 by 8, we get 56. Adding 49 to 56 gives us the next number in the sequence: 105.
So, the long answer is that the number which best completes the sequence is 56, and the next number in the sequence after that would be 105. The sequence can be split into two sub-sequences: 20, 30, 42 and 5, 6, 7. The first sub-sequence represents an increasing series of even numbers (20, 30, 42) with a difference of 10, 12, and so on. The second sub-sequence represents a consecutive series of odd numbers (5, 6, 7). Combining these sub-sequences forms the original sequence.

.A ball that is dropped from a window hits the ground in 7 seconds. How high is the window? (Give your answer in feet; note that the acceleration due to gravity is 32 ft/s² . Height = _______
Answers
Answer:
(1/2)(32 ft/sec^2)((7 sec)^2)
= (16 ft/sec^2)(49 sec^2)
= 784 feet
Height = 112 feet.
To find the height of the window, we can use the following kinematic equation for motion with constant acceleration:
y = yo + voyt + ½at²
Here, y is the final height of the ball above the ground, yo is the initial height of the ball (which is the height of the window in this case), voy is the initial velocity of the ball (which is 0 because the ball is dropped from rest), t is the time taken for the ball to hit the ground (which is 7 seconds), and a is the acceleration due to gravity (which is 32 ft/s²).
Substituting the values, we have:y = yo + 0 + ½(32)(7)
Simplifying the expression, we get:y = yo + 112
Thus, the height of the window (in feet) is given by:y = 112 feet

Answers
The Yule-Walker equations relate the autocovariance function of a stationary time series to its autocorrelation function. In this case, we are interested in finding the autocovariance function.
The Yule-Walker equations for an AR(2) process can be written as follows:
r_X(0) = Var(X_t) = σ^2
r_X(1) = ρ_X(1) * σ^2
r_X(2) = ρ_X(2) * σ^2 + ρ_X(1) * r_X(1)
Here, r_X(k) represents the autocovariance at lag k, ρ_X(k) represents the autocorrelation at lag k, and σ^2 is the variance of the white noise innovation process e_t.
In our case, we are given that V(e_t) = 4, so σ^2 = 4. Now we need to find the autocorrelations ρ_X(1) and ρ_X(2) to compute the autocovariances.
Since X_t is an AR(2) process, we can rewrite the Yule-Walker equations in terms of the AR parameters as follows:
1 = φ_1 + φ_2
0.5 = φ_1 * φ_2 + ρ_X(1) * φ_2
0 = φ_2 * ρ_X(1) + ρ_X(2)
Solving these equations will give us the values of ρ_X(1) and ρ_X(2), which we can then use to compute the autocovariances r_X(0), r_X(1), and r_X(2).

b. 18.676765
c. 17.455483
d. 17.585794
e. 18.076686
Answers
Option A is the correct answer. Ellora wants to accumulate 150,000 in an RRSP by making annual contributions of 5,000 at the beginning of each year. If interest is 5.5% compounded quarterly, calculate how long she has to make contributions.
First, we have to find the interest rate per quarter, which will be
\(5.5% / 4\)= 1.375%.
The formula for the future value of an annuity is:
\(FV = (C * [(1 + r)^n - 1] / r)\),
For Ellora, \(FV = $150,000, C = $5,000, and r = 1.375%.\)
Substituting these values into the formula gives:
\(150,000 = 5,000 * [(1 + 0.01375)^n - 1] / 0.01375\)
Simplifying this equation gives:
\(30 = [(1.01375)^n - 1]\)
We can solve this using logarithms:
\(ln 30 = ln [(1.01375)^n - 1]\)
\(ln 30 = n * ln 1.01375 - ln 1.01375e^(ln 30) / e^(-ln 1.01375) = n18.202125 = n\)
Therefore, it will take Ellora 18.202125 years to accumulate 150,000 in her RRSP through \($5,000\)annual contributions made at the beginning of each year with interest of \(5.5%\) compounded quarterly.

Sussman Industries purchased a drilling machine for $100,000 and paid cash. Sussman expects to use the machine for 20 years, after which it will have no value. It will be depreciated straight-line over the 20 years. Assume a tax rate of 37%. What are the cash flows associated with the machine? Round the answers to the nearest whole dollar. Show inflows as positives and outflows as negatives (using the sign "-").
a. what is the amount at the time of purchase
b. What is the amount In each of the following 20 years
Answers
The cash flows for the depreciation per year for the 20 years are estimated.
a. Amount at the time of purchase is $-100,000 (Negative because it is an outflow)
b. Amount in each of the following 20 years:
The straight-line depreciation rate can be calculated by dividing the purchase price by the number of years the asset is expected to last.
Here, the purchase price is $100,000 and the expected life is 20 years.
Depreciation per year = Purchase price / Expected life
= $100,000 / 20
= $5,000 per year (constant for 20 years)
For each of the 20 years, the cash flows are as follows:
Year 1: -$5,000 (depreciation expense)
Year 2: -$5,000 (depreciation expense)
Year 3: -$5,000 (depreciation expense)

Answers
The number of heart cakes that were sold at the cake sale was 28
According to the question,
Cost of circular-shaped cake = $7
Cost of heart shaped cake = $5
Total sale = $238
Let the number of circular cakes shaped be x
Since the number of heart cakes was sold twice as many as the circular cake, the number of heart cakes will be 2x
Cost of x circular-shaped cake = $7 * x
Cost of 2x heart shaped cake = $5 * 2x
Total sale = Cost of x circular cake + Cost of 2x heart cake
Thus, we get the following equation,

find the standard equation of the sphere. (let r = 8 and c = (9, 2, 5).)
Answers
The standard equation of the sphere is:
x^2 + y^2 + z^2 - 18x - 4y - 10z + 46 = 0
The standard equation of a sphere is given by:
(x - a)^2 + (y - b)^2 + (z - c)^2 = r^2
where (a, b, c) is the center of the sphere and r is the radius.
In this case, the center of the sphere is given by c = (9, 2, 5) and the radius is r = 8.
Substituting these values into the standard equation of the sphere, we get:
(x - 9)^2 + (y - 2)^2 + (z - 5)^2 = 8^2
Expanding and simplifying, we get:
x^2 - 18x + 81 + y^2 - 4y + 4 + z^2 - 10z + 25 = 64
x^2 + y^2 + z^2 - 18x - 4y - 10z + 46 = 0

Answers
The Kutta-Joukowski theorem, which is represented by equation (3.140), was originally derived for the case of a lifting cylinder. However, it can also be applied to a two-dimensional body of arbitrary shape, as stated in section 3.16.
A more detailed explanation of the answer.
To make a physical argument for this generalization, we can draw a closed curve around the body.
The key is to draw the curve far enough away from the body such that the body appears as a very small speck in the middle of the domain enclosed by the closed curve.
By doing this, we are essentially treating the body as a point object at the center of the curve. Since the body is now a very small speck in comparison to the large domain, its specific shape becomes insignificant to the overall flow around it.
Therefore, the lifting force calculations derived from the Kutta-Joukowski theorem for the lifting cylinder should also apply to the two-dimensional body of arbitrary shape, as long as the body is small in comparison to the domain enclosed by the closed curve.
This physical argument allows us to accept that equation (3.140) can be applied in general to a two-dimensional body of arbitrary shape without requiring a mathematical proof.

The rate (m) is then calculated as:
\(m = \frac{y_2 - y_1}{x_2 - x_1}\)
So, we have:
\(m = \frac{9-4}{20-10}\)
\(m = \frac{5}{10}\)
\(m = 0.5\)
Pick another point from the table
\((x_1,y_1) = (10,4)\)
\((x_2,y_2) = (30,10)\)
The rate (m) is then calculated as:
\(m = \frac{y_2 - y_1}{x_2 - x_1}\)
\(m = \frac{10 - 4}{30 - 10}\)
\(m = \frac{6}{20}\)
\(m = 0.3\)
The rates calculated are not equal
i.e. 0.3 and 0.5 are not equal
This means that;

Jenny is making jewelry craft kits. She purchases 3 bags of each color band. She divides the total number of bands equally into 4 kits. How many bands are in each kit?
Answers
Answer:
12
Step-by-step explanation:
Given:
3 bags of each color band
4 kits
To "divide equally" we need the greatest number that divides the two numbers 3 and 4 equally.
Find the greatest common factor of 3 and 4:
factors of 3 = 1,3,6,9,12,15,18,21,24....
factors of 4 = 1,2,4,8,12,16,20,24...
How many bands are in each kit?
12 or any other number that is a factor of both 3 and 4 such as 24,..etc.
