Answer:

The answer should be y = -\(\frac{3}{2}\)\(x\) + 8, but its not one of the answers, so check the question again.

Step-by-step explanation:

If the second line is parallel, then the gradient will be the same:

y = -\(\frac{3}{2}\)\(x\) + c

Find what c is (y-intercept) by inputting the given point into the equation (4,2):

2 =  (-\(\frac{3}{2}\) x 4) + c

2 = -6 + c

c = 8

The variance of each random variable is given as follows:

a) Var(2x - y) = 10.4165.

b) Var(x + 3y - 5) = 20.833.

The number that occurs when each dice is thrown is represented by an uniform variable, with bounds a = 1 and b = 6, hence the variance of each variable is calculated as follows:

Var(x) = Var(y) = (6 - 1)²/12 = 2.0833.

When two variables are added, the variance is calculated as follows:

Var(aX + bY) = a²Var(X) + b²Var(Y)

Hence, for item a, the variance is calculated as follows:

Var(2x - y) = 2²Var(x) + (-1)²Var(y) = 4Var(x) + Var(y)

The variances were calculated before, which are both of 2.0833, hence:

4Var(x) + Var(y) = 4 x 2.0833 + 2.0833 = 10.4165.

For item b, the variance is calculated as follows:

Var(x + 3y - 5) = Var(x) + 3²Var(y) + (-1)²Var(-5).

The variance of a constant is of zero, hence Var(-5) = 0, and then:

Var(x + 3y - 5) = Var(x) + 3²Var(y) + (-1)²Var(-5) = 2.0833 + 9(2.0833) = 20.833.

The slope of a line that is parallel to the line containing the points (3, 4) and (2, 6) is -2.

To find the slope of a line that is parallel to the line containing the points (3, 4) and (2, 6), we first need to find the slope of the line containing these points. We can use the slope formula:

m = (y2 - y1) / (x2 - x1)

Where:

m = slope

(x1, y1) = coordinates of the first point (3, 4)

(x2, y2) = coordinates of the second point (2, 6)

Substituting the given values, we get:

m = (6 - 4) / (2 - 3)

m = -2

The slope of the line containing the points (3, 4) and (2, 6) is -2.

Since we are looking for a line that is parallel to this line, the slope of the parallel line will also be -2.

Therefore, the slope of the parallel line is -2.

The perimeter of a rectangle is the total distance around the outside of the rectangle. It is calculated by adding together the length of all four sides of the rectangle. If the length of the rectangle is denoted by 'l' and the width is denoted by 'w', then the formula for the perimeter (P) of the rectangle is:

P = 2l + 2w

Alternatively, the formula can also be written as:

P = 2(l + w)

The perimeter of a rectangle is given by the sum of the lengths of all four sides. Therefore, we can write:

AB + BC + CD + DA = 22

We know that AB = CD = 9 since they are opposite sides of the rectangle. We also know that DA = BC = x - 5, since they are the other two sides of the rectangle.

Substituting these values into the perimeter equation, we get:

9 + x - 5 + 9 + x - 5 = 22

Simplifying the equation, we get:

2x - 2 = 22

2x = 24

x = 12

Therefore, the value of x could be 12.

The first expression  X (Y + Z) = X.Y + X.Z is distributive property of multiplication and the second expression X(Y.Z) = (X.Y)Z = X.Y.Z is associative property of multiplication.

According to the question,

We have the following two expressions:

X (Y + Z) = X.Y + X.Z

X(Y.Z) = (X.Y)Z = X.Y.Z

Now, the distributive property of multiplication states that the number outside the bracket is multiplied into each number within the bracket and the sign remains the same.

For example, 2(5+7) is 2*5+2*7.

The associative property of multiplication states that the result of the multiplication of numbers is same even when the bracket is changed from one number to another.

Hence, the first expression  X (Y + Z) = X.Y + X.Z is distributive property of multiplication and the second expression X(Y.Z) = (X.Y)Z = X.Y.Z is associative property of multiplication.

The second expression X(Y.Z) = (X.Y)Z = X.Y.Z uses the associative property of multiplication.

Boolean Algebra:

Basically, Boolean algebra is a branch of mathematics that deals with operations on logical values with binary variables.

And there are three properties in Boolean algebra.

They are, Commutative, associative, and distributive properties.

Given,

Sam’s teacher wrote two Boolean expressions on the whiteboard. Identify the names of the laws of these expressions.

Expression 1: X (Y + Z) = X.Y + X.Z

Expression 2: X(Y.Z) = (X.Y)Z = X.Y.Z

Here we need to find the name of the property used by the teacher on those two expression.

While we looking into the question,

We have the give the two expressions:

They are

=> X (Y + Z) = X.Y + X.Z

=> X(Y.Z) = (X.Y)Z = X.Y.Z

When we take the first expression,

X (Y + Z) = X.Y + X.Z

That states that the distributive property of multiplication is used here and the process of the distribution property is the number outside the bracket is multiplied into each number within the bracket and the sign remains the same.

Similarly, when we take the second expression

X(Y.Z) = (X.Y)Z = X.Y.Z

That uses the associative property of multiplication which is the result of the multiplication of numbers is same even when the bracket is changed from one number to another.

What is a linear equation?

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

Here, we have

The company must have produced 60 items daily if it produced 20 more than the daily average of 40 items.

The company had 120 products to make, which should have taken three days (120 items, 40 items/day), but it finished in just two days (120 items, 60 items/day). They completed this order one day earlier than expected.

However, the issue is that they completed 3 days ahead of schedule. Thus, our estimate is 360 items or three times 120 items.

According to this, they should have completed their order in 9 days (360 things, at a rate of 40 items per day), but they did so in 6, at a rate of 60 items per day. Since 6 is three fewer than 9, our assumption of 360 items was accurate.

We've demonstrated that the business should have completed the order in 9 days.

Let the desired number of days be x.

Then, the company finished its order in x - 3 days.

Since the number of items produced is the number of days times items per day, and it doesn't change:

number of items = 40 items/day * x days

= 60 items/day * (x - 3) days

40x = 60(x - 3) = 60x - 180

180 = 20x

x = 9

Hence, the company was supposed to finish the order in 9 days.

The total derivative of Z with respect to t is given by

\(Z' = (-2e^{-2t})(t + 3/(3e^{-2t} + 3t^2 - t)).\)

We have,

To find the total derivative of Z with respect to t, we can apply the chain rule and the product rule.

Let's calculate it step by step:

Given:

z = tx + ln(3x + y)

\(x = e^{-2t}y = 3t^2 - t\)

We'll start by finding the derivative of z with respect to x, and then multiply it by the derivative of x with respect to t:

dz/dx = t + 1/(3x + y) * (3)

= t + 3/(3x + y)

Next, we'll find the derivative of x with respect to t:

\(dx/dt = d/dt(e^{-2t})\\= -2e^{-2t}\)

Now, applying the chain rule, we can find the derivative of z with respect to t:

dz/dt = dz/dx * dx/dt

\(= (t + 3/(3x + y)) * (-2e^{-2t})\)

Substituting the expressions for x and y, we have:

\(dz/dt = (t + 3/(3e^{-2t} + 3t^2 - t)) * (-2e^{-2t})\)

Simplifying further, we can rewrite it as the total derivative of Z with respect to t:

\(Z' = (-2e^{-2t})(t + 3/(3e^{-2t} + 3t^2 - t))\)

Thus,

The total derivative of Z with respect to t is given by

\(Z' = (-2e^{-2t})(t + 3/(3e^{-2t} + 3t^2 - t)).\)

47 = -2 - 7x

7x = -2 - 47

7x = -49

x = -7

The real zeros of f(x) are x = -2, x = 1/5, and x = 7/5.

The smallest real zero is x = -2, and the largest real zero is x = 7/5.

Given function is :\(f(x) = 10x3- 7x2 - 139x + 28\).

Now we have to Verify the given factors of the function f which is \((2x + 7), (5x - 1)\).

The Remainder Theorem states that when a polynomial f(x) is divided by a divisor x - c, the remainder is equal to f(c).

Now we will divide f(x) by 2x+7 using polynomial long division.

\(\[\begin{align}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 5x^2&-8x+4 \\2x+7|10x^3-7x^2-139x+28& \\ \ \ \ \ \ \ \ \ \ \ \ \ -\underline{(10x^3+35x^2)}& \\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ -42x^2-139x& \\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \underline{(\ \ 42x^2+147x\ )}& \\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ -8x+28& \end{align}\]\)

Now the remaining factor of f(x) is (2x + 7) (5x - 1) (2x - 2), which is further simplified to f(x) = 10(x + 2)(5x - 1)(x - 7/5).

Hence the factorization of the given function is f(x) = 10(x + 2)(5x - 1)(x - 7/5).

The real zeros of f(x) can be found by setting f(x) = 0.

\(\[\begin{align}f(x)&=0 \\10(x+2)(5x-1)(x-\frac{7}{5})&=0 \\x+2&=0\ \ \ \ \ \ \ \ \ \ \ 5x-1=0\ \ \ \ \ \ \ \ \ \ \ x-\frac{7}{5}=0\\x&=-2\ \ \ \ \ \ \ \ \ \ \ x=\frac{1}{5}\ \ \ \ \ \ \ \ \ \ \ x=\frac{7}{5}\end{align}\]\)

Thus, the real zeros of f(x) are x = -2, x = 1/5, and x = 7/5.

The smallest real zero is x = -2, and the largest real zero is x = 7/5.

To find the reference angle of a negative angle, follow these steps:

Determine the positive equivalent: Add 360 degrees (or 2π radians) to the negative angle to find its positive equivalent. This step is necessary because reference angles are always positive.

Subtract from 180 degrees (or π radians): Once you have the positive equivalent, subtract it from 180 degrees (or π radians). This step helps us find the angle that is closest to the x-axis (or the positive x-axis) while still maintaining the same trigonometric ratios.

For example, let's say we have a negative angle of -120 degrees. To find its reference angle:

Positive equivalent: -120 + 360 = 240 degrees

Subtract from 180: 180 - 240 = -60 degrees

Therefore, the reference angle of -120 degrees is 60 degrees.

In summary, to find the reference angle of a negative angle, first, determine the positive equivalent by adding 360 degrees (or 2π radians). Then, subtract the positive equivalent from 180 degrees (or π radians) to obtain the reference angle.
