Given the linear functions f(x) = x -2 and g(x)=-3x + 4, determine (f- g)(x).
(f-g)(x) = -3x - 8
(f-g)(x)=-3x²-8
(f-g)(x) = -3x² + 10x - 8
(f-g)(x) = -3x² - 2x - 8
The expression for the difference of two linear functions is (f - g)(x) = 4x - 6.
What is linear function?A linear function is a type of function in mathematics that has the form f(x) = mx + b, where x is the independent variable, f(x) is the dependent variable, m is the slope of the line, and b is the y-intercept.
According to given information:To find the expression for the difference of two linear functions, f(x) and g(x), denoted by (f - g)(x).
The expression for (f - g)(x) can be found by subtracting g(x) from f(x):
(f - g)(x) = f(x) - g(x)
Substituting the given functions f(x) = x - 2 and g(x) = -3x + 4, we get:
(f - g)(x) = f(x) - g(x)
= (x - 2) - (-3x + 4) [Substitute the given values of f(x) and g(x)]
= x - 2 + 3x - 4 [Distribute the negative sign in front of (-3x + 4)]
= 4x - 6 [Combine like terms]
Therefore, (f - g)(x) = 4x - 6.
Option D (-3x² - 2x - 8) is incorrect as it involves squaring a linear expression, which would result in a quadratic expression. Option A (which has no operation between 3 and 22) is not a valid expression. Option B (-3x - 8) and C (3x3x22 or 198) do not take into account the fact that each sundae can be made using one of 3 syrups and one of 3 candy toppings.

Answer:
x = 54
Step-by-step explanation:
In this line, I am going to assume lines l and m are parallel.
Each flat surface is half of a circle, therefore it has 180 degrees. We are given one side and told to find the other.
180 - 116 = 64.
The other angle's total value must be 64.
Now, to solve for x, subtract 10 from 64 [inverse operations].
64-10=54
The value of x in this equation is 54 degrees.

the 2014-t6 aluminium rod has a diameter of 30 mm and supports the load shown where d = 2.25 m. (figure 1) neglect the size of the couplings.
The 2014-t6 aluminium rod has a diameter of 30 mm and supports the load is 0.025 mm
To determine the suitability of the 2014-t6 aluminum rod for supporting the given load, we need to consider its strength and stability. The diameter of the rod is given as 30 mm, which we can use to calculate its cross-sectional area as πr^2, where r is the radius (15 mm in this case).
Assuming that the load is uniformly distributed along the rod's length, we can calculate the maximum bending moment it can sustain using the formula Mmax = WL/8, where W is the total load and L is the distance between the supports (d = 2.25 m).
If we substitute the given values, we get Mmax = 5000 N * 2.25 m / 8 = 1406.25 Nm. We can then use the formula for the bending stress in a circular beam, σ = Mc/I, where c is the distance from the neutral axis to the outermost fiber (half the diameter) and I is the moment of inertia of the cross-section.
For a solid circular section, I = πr^4/4, and c = r. Plugging in the values, we get σ = (1406.25 Nm * 0.015 m) / (π * 0.015^4 / 4) = 10.15 MPa.
Comparing this value to the yield strength of 2014-t6 aluminum (around 390 MPa), we can see that the rod should be able to support the load without exceeding its yield strength. However, we also need to ensure that the deflection of the rod is within acceptable limits.
Using the formula for the deflection of a cantilever beam, δ = WL^3/3EI, where E is the modulus of elasticity of the material, we can calculate the maximum deflection as δ = 5000 N * (2.25 m)^3 / (3 * 70 GPa * π * 0.015^4 / 4) = 0.025 mm. This is a very small deflection, which suggests that the rod should be stable under the given load.

A manufacturer knows that their items have a normally distributed lifespan, with a mean of 11 years, and standard deviation of 0.9 years.The 15,87% of items with the shortest lifespan will last less than how many years?
The 15.87% of items with the shortest lifespan will last less than approximately 9.066 years.
To find the number of years that the 15.87% of items with the shortest lifespan will last, we need to determine the corresponding z-score and then use it to find the corresponding value on the standard normal distribution.
First, we need to find the z-score corresponding to the given percentage. The z-score represents the number of standard deviations away from the mean. The area under the standard normal curve to the left of a z-score represents the percentage of values below that z-score.
Using a standard normal distribution table or a calculator, we can find that the z-score corresponding to a cumulative area of 15.87% is approximately -1.036. This means that the 15.87% of items with the shortest lifespan will have a z-score of -1.036.
Next, we can use the formula for z-score transformation to find the corresponding value on the normal distribution:
z = (X - μ) / σ
where X is the value we want to find, μ is the mean, and σ is the standard deviation.
Rearranging the formula, we have:
X = z * σ + μ
Plugging in the values, we get:
X = -1.036 * 0.9 + 11
Calculating this, we find:
X ≈ 9.066
Therefore, the 15.87% of items with the shortest lifespan will last less than approximately 9.066 years.

What is the value of x?
Answer:
x = 14 y = 37
Step-by-step explanation:
180 - (9x + 12) = 3x
180 - 9x - 12 = 3x
168 = 12x
x = 14
4y - 10 + 3(14) = 180
4y - 10 + 42 = 180
4y + 32 = 180
4y = 148

Sara and jo both ran an 8km race Sarah took 55 mins to run the whole race jo started the race 3 mins later than Sara but caught up when they had both travelled 6 km of Sara and jo both ran at constant speed what is jos speed in 2dp
Answer:
9.41 km/h
Step-by-step explanation:
The total distance of the race, d = 8 km
The time Sarah took to run the race, t = 55 mins
The time Jo started the race = 3 mins later than Sara
The point Jo caught up with Sarah = 6 km into the race
The rate at which Jo and Sarah ran = Constant speed
The required information = Jo's speed
From the information given, Sarah's speed, v = 8 km/(55 mins) = (8/55) km/min × 60min/h = 96/11 km/h
The time it would take Sarah to run 6 km = 6 km/(8 km/(55 mins)) = 41.25 mins
Given that Jo started 3 minutes late, and they both arrive at 6 km into the race at the same point in time, the time it took Jo to arrive at 6 km into the race = The time it took Sarah - 3 minutes
∴ The time it took Jo to run the 6 km = 41.25 minutes - 3 minutes = 38.25 minutes
Given that Jo ran at a constant speed, and speed = distance/time, we have;
Jo's speed = 6 km/(38.25 min) = 8/51 km/min × 60 min/h = (160/17) km/h ≈ 9.41 km/h.

suppose that a has order 15. find all of the left cosets of ka5l in kal.
To find all of the left cosets of ka5l in kal, we multiply the element ka5l by each power of a in kal. Since a has order 15, there will be 15 left cosets in total. Each left coset will contain 15 elements.
Let's start by finding the element ka5l. Since the specific values of ka5l and a^i are not provided, we'll use the general notation.
The left cosets of ka5l in kal are obtained by multiplying each element of ka5l by the elements of kal. In this case, we'll consider the powers of a from a^0 to a^14.
The left cosets can be represented as follows:
ka5l * a^0 = {ka5l * a^0, ka5l * a^1, ka5l * a^2, ..., ka5l * a^14}
ka5l * a^1 = {ka5l * a^1, ka5l * a^2, ka5l * a^3, ..., ka5l * a^15}
ka5l * a^2 = {ka5l * a^2, ka5l * a^3, ka5l * a^4, ..., ka5l * a^16}
...
ka5l * a^14 = {ka5l * a^14, ka5l * a^15, ka5l * a^16, ..., ka5l * a^28}
Each set represents a left coset, and each left coset contains 15 elements. The total number of left cosets is 15, corresponding to the order of a.
It's important to note that the specific values of ka5l and a^i may vary depending on the context or given information. Substitute the actual values accordingly to determine the elements of each left coset.

Suppose that the daily log return of a security follows the model rt = 0.02 +0.5rt-2 + et where {e} is a Gaussian white noise series with mean zero and variance0.02. What are the mean and variance of the return series rt? Compute the lag-1 and lag-2 autocorrelations of rt. Assume that r100 = -0.01, and r99 = 0.02. Compute the 1- and 2-step-ahead forecasts of the return series at the forecast origin t = 100. What are the associated standard deviation of the forecast errors?
Mean of rt = 0.02,
Variance of rt = 0.02,
Lag-1 Autocorrelation (ρ1) = -0.01,
Lag-2 Autocorrelation (ρ2) = Unknown,
1-step ahead forecast = -0.005,
2-step ahead forecast = 0.02,
The standard deviation of forecast errors = √0.02.
We have,
To find the mean and variance of the return series, we can substitute the given model into the equation and calculate:
Mean of rt:
E(rt) = E(0.02 + 0.5rt-2 + et)
= 0.02 + 0.5E(rt-2) + E(et)
= 0.02 + 0.5 * 0 + 0
= 0.02
The variance of rt:
Var(rt) = Var(0.02 + 0.5rt-2 + et)
= Var(et) (since the term 0.5rt-2 does not contribute to the variance)
= 0.02
The mean of the return series rt is 0.02, and the variance is 0.02.
To compute the lag-1 and lag-2 autocorrelations of rt, we need to determine the correlation between rt and rt-1, and between rt and rt-2:
Lag-1 Autocorrelation:
ρ(1) = Cov(rt, rt-1) / (σ(rt) * σ(rt-1))
Lag-2 Autocorrelation:
ρ(2) = Cov(rt, rt-2) / (σ(rt) * σ(rt-2))
Since we are given r100 = -0.01 and r99 = 0.02, we can substitute these values into the equations:
Lag-1 Autocorrelation:
ρ(1) = Cov(rt, rt-1) / (σ(rt) * σ(rt-1))
= Cov(r100, r99) / (σ(r100) * σ(r99))
= Cov(-0.01, 0.02) / (σ(r100) * σ(r99))
Lag-2 Autocorrelation:
ρ(2) = Cov(rt, rt-2) / (σ(rt) * σ(rt-2))
= Cov(r100, r98) / (σ(r100) * σ(r98))
To compute the 1- and 2-step-ahead forecasts of the return series at
t = 100, we use the given model:
1-step ahead forecast:
E(rt+1 | r100, r99) = E(0.02 + 0.5rt-1 + et+1 | r100, r99)
= 0.02 + 0.5r100
2-step ahead forecast:
E(rt+2 | r100, r99) = E(0.02 + 0.5rt | r100, r99)
= 0.02 + 0.5E(rt | r100, r99)
= 0.02 + 0.5(0.02 + 0.5r100)
The associated standard deviation of the forecast errors can be calculated as the square root of the variance of the return series, which is given as 0.02.
Thus,
Mean of rt = 0.02,
Variance of rt = 0.02,
Lag-1 Autocorrelation (ρ1) = -0.01,
Lag-2 Autocorrelation (ρ2) = Unknown,
1-step ahead forecast = -0.005,

Generating a random real number (can have decimal numbers) between 1.0 and 10.0. (5 points) = RANDBETWEEN (1,10) =1.0+ RAND 0
∗
9.0 =RANDBETWEEN (1.0,10.0) -RAND(1.0,10.0)
The random real number between 1.0 and 10.0 can be generated using the formula: 1.0 + (RAND() * 9.0).
To generate a random real number within a specified range, we can use the RAND() function. The RAND() function generates a random decimal number between 0 and 1.0. By multiplying this random number by the range of values we desire and adding the minimum value, we can obtain a random real number within the desired range.
In this case, we want a random number between 1.0 and 10.0. To achieve this, we multiply the random number generated by RAND() by the range, which is 9.0 (10.0 - 1.0). This scales the random number to the desired range. Then, by adding 1.0 (the minimum value) to the scaled random number, we obtain the final random real number within the range of 1.0 and 10.0.
To summarize, the formula for generating a random real number between 1.0 and 10.0 is: 1.0 + (RAND() * 9.0).
