Answer:

1. x^2 -2x + x+10  = x^2-x-10

2. x^2-3x -10

3. 11x^ 3 −22x^ 2

4. x-2/11

Step-by-step explanation:

 f(x) x^2 -2x and g|(X) x + 10

1) f+g

f+g is f(x) + g(x) = x^2 -2x + x + 10  = x^2 -x -10 and you could write highest degree first if not already shown = x^2 -2x + x+10  

2) f-g

f-g = f(x) = g(x) = x^2-2x - x+10 = x^2-3x -10

3) fg

fg = f (x)  x  g(x) = (x^2-2x) x (x+10) = 11x^ 3 −22x^ 2

4) f/g

f/g = f(x) / g(x) = x^2- 2x/11x  = x-2/11

Answer:

graph{y=4x+1 [-10, 10, -5, 5]}

Step-by-step explanation:

Since the equation is linear/straight in the form

y = mx + c, you can determine the slope/gradient (m) and y-intercept (c).

m = 4

c = 1

To graph this equation, you'll need to find 2 points on the line and join them together. We know one of the points is (0, 1) as the y-intercept is 1.

You can find another point by substituting an arbitrary number into

x or y in the equation. In this example, I'll substitute 1 into x to find the y coordinate where the x coordinate is 1.

y = 4 (1) + 1

y = 4 + 1

y = 5

So, the second point would be (1, 5).

If you join the points (0, 1) and (1, 5) on a graph, this would be the line of the equation.

hope this helps!

The coordinates for the point for this equation  \(y - 4 = -\frac{1}{3} (x-7),\) is at (7, 4)

The standard form of the equation in point-slope form is expressed as:

\(y-y_0=m(x-x_0)\\\)

m is the slope of the line

\((x_0, y_0)\) is any point on the line

Given the equation \(y - 4 = -\frac{1}{3} (x-7),\)

Compare the original equation with the given equation to get the coordinate for the point \((x_0, y_0)\).

On comparison:

\(-x_0=-7\\x_0=7\\-y_0=-4\\y_0=4\)

Hence the coordinates for the point is at (7, 4)

To determine the exposure from a radioactive substance at a different distance, we can use the inverse square law. The exposure at a distance of 20 cm is 11,250 mR.

The inverse square law states that the intensity of radiation is inversely proportional to the square of the distance from the source. In this case, we have the initial distance of 100 cm and the corresponding exposure of 450 mR.

Using the inverse square law equation, we can set up a proportion to find the new exposure at a distance of 20 cm. The equation can be written as:

(Exposure at initial distance) / (Exposure at new distance) = (Square of new distance) / (Square of initial distance)

Substituting the given values, we have:

450 mR / X = \((20 cm)^2 / (100 cm)^2\)

Simplifying the equation, we get:

450 mR / X = 1/25

Cross-multiplying, we have:

X = (450 mR) * (25)

Calculating the value, we find:

X = 11,250 mR

Therefore, the exposure at a distance of 20 cm is 11,250 mR.

The 2.8 liter is refers to the engine's displacement or volume

In the context of an engine, "2.8 liter" typically refers to the engine's displacement or volume. Specifically, it means that the engine can hold 2.8 liters (or 2,800 cubic centimeters) of air and fuel mixture in its cylinders.

The displacement of an engine is an important factor in determining its power and performance characteristics, as it influences the amount of air and fuel that can be burned during each engine cycle.

Generally, larger engine displacements are associated with more power and torque, although other factors such as the engine's design and technology also play a role.

Therefore, 2.8 liter is engine displacement

The correct answer is d) All of the above. Regression analysis results are often abused by using the model without understanding its context, predicting outside the data range without acknowledging extrapolation, and disregarding known scientific and economic theories related to the model and its variables.

Regression analysis is a statistical method used to examine the relationship between variables and make predictions based on the observed data. However, the misuse and misinterpretation of regression analysis can lead to erroneous conclusions.

Firstly, using the model without understanding its context can be problematic. The development and recommendation of a regression model are typically based on specific assumptions and limitations, as well as the data used in its construction. Applying the model to a different context without considering these factors may lead to inaccurate predictions or interpretations.

Secondly, predicting outside the region of the data without recognizing that it involves extrapolation is another common misuse of regression analysis. Extrapolation involves making predictions beyond the observed data range, which can be risky since the relationship between variables may not hold true outside the data range. Extrapolation should be approached cautiously and accompanied by a clear acknowledgement of its inherent uncertainties.

Lastly, ignoring known scientific and economic theory related to the model and its variables can also lead to misuse. Regression analysis should be interpreted in the context of existing theories and domain knowledge. Disregarding established theories can result in flawed conclusions or invalid interpretations of the regression model's results.

In conclusion, regression analysis should be used with care and understanding. It is crucial to consider the context, acknowledge the limitations of extrapolation, and incorporate relevant scientific and economic theories to ensure the appropriate use and interpretation of regression analysis results.

Answer:

The largest interior angle of ΔCDF is ∠F

Step-by-step explanation:

The bearings of the vertices of the triangle are given as follows;

The bearing of C from D = 056°

The bearing of F from D = 115°

The bearing of F from C = 184°

By angle addition property, we have;

The bearing of F from D = The bearing of C from D + ∠D

∴ ∠D = The bearing of F from D - The bearing of C from D

By plugging in the values, we have;

∠D = 115° - 056° = 59°

∠D in triangle ΔCDF = 59°

∠D = 59°

By alternate interior angles, we have;

The bearing of C from D = 056° = ∠BCD

Also, we have;

The bearing of F from C = ∠BCF + ∠ACB

∠ACB = 180°

∴ ∠BCF = The bearing of F from C - ∠ACB

∠BCF = 184 - 180° = 4°

∠C in ΔCDF = ∠BCD - ∠BCF

∴ ∠C = 056° - 4° = 52°

∠C = 52°

From angle sum property of ΔCDF, we have; ∠F = 180° - ∠C - ∠D

Therefore; ∠F = 180° - 52° - 59° = 69°

We have; ∠C = 52°, ∠D = 59°, ∠F = 69°, therefore;

∠F in triangle ΔCDF, has the largest interior angle.

Answer:

- Reflected over the x-axis  

- Compressed by a factor of 0.4.

- Translated 2 units left

Step-by-step explanation:

Given

\(y = \sqrt[3]{x}\)

\(y' = -(0.4)\sqrt[3]{x-2}\)

Required

The transformation from y to y'

First, y is reflected over the x-axis.

The transformation rule is:

\((x,y) \to (x,-y)\)

So, we have:

\(y = \sqrt[3]{x}\) becomes

\(y' = -\sqrt[3]{x}\)

Next, it was compressed by a scale factor of 0.4

The rule is:

\(y' = k * y\)

Where k is the scale factor (i.e. k = 0.4)

So, we have:

\(y' = 0.4 * -\sqrt[3]{x}\)

\(y' = -(0.4)\sqrt[3]{x}\)

Lastly, the function is translated 2 units left;

The rule is:

\((x,y) \to (x-2,y)\)

So, we have:

\(y' = -(0.4)\sqrt[3]{x - 2}\)

-reflected over the x-axis

Compute the Gaussian density for the following cases. (a) x=0, m=0, s-1. Give the name of question5a (b) x-2, m=0, s-1. The value of the account on January 1, 2021, would be $2,331.57.

To calculate the value of the account on January 1, 2021, we need to consider the compounding interest for each year.

First, we calculate the value of the initial deposit after three years (12 quarters) using the formula for compound interest:

Principal = $1,000

Rate of interest per period = 8% / 4 = 2% per quarter

Number of periods = 12 quarters

Value after three years = Principal * (1 + Rate of interest per period)^(Number of periods)

                           = $1,000 * (1 + 0.02)^12

                           ≈ $1,166.41

Next, we calculate the value of the additional $1,000 deposit made on January 1, 2019, after two years (8 quarters):

Principal = $1,000

Rate of interest per period = 2% per quarter

Number of periods = 8 quarters

Value after two years = Principal * (1 + Rate of interest per period)^(Number of periods)

                         = $1,000 * (1 + 0.02)^8

                         ≈ $1,165.16

Finally, we add the two values to find the total value of the account on January 1, 2021:

Total value = Value after three years + Value after two years

                ≈ $1,166.41 + $1,165.16

                ≈ $2,331.57

Therefore, the value of the account on January 1, 2021, is approximately $2,331.57.
