Answer:

-17x^3-10x^2+x+9

Answer:

$36.33

Step-by-step explanation:

So, when finding the percentage of a number you move the decimal point to the left two times.

39.93 x .15 = 6

39.93 - 6 = 33.93

(I subtracted the 6 because it was what was taken off by the coupon)

33.93 x .07 = 2.4

33.93 + 2.4 = 36.33

(Again, I added the 2.4 because it was what was added on by the sales tax)

I hope this helps! :)

Using the vertex of the quadratic equation, it is found that the profit will be maximized when each cookbook is sold for $8.25.

A quadratic equation is modeled by:

\(y = ax^2 + bx + c\)

The vertex is given by:

\((x_v, y_v)\)

In which:

\(x_v = -\frac{b}{2a}\)

\(y_v = -\frac{b^2 - 4ac}{4a}\)

Considering the coefficient a, we have that:

In this problem, the function is modeled as follows, considering x as the price divided by $0.05.

P(x) = -0.1x² + 15x + 120.

The coefficients are a = -0.1 < 0, b = 15, c = 120, hence the x-value of the vertex is given by:

\(x_v = -\frac{15}{2(-0.1)} = \frac{15}{0.2} = 75\)

75 increases of $0.05, hence the price will be of:

4.5 + 75 x 0.05 = $8.25.

Hence, the profit will be maximized when each cookbook is sold for $8.25.

Answer:

Let's call the total number of people who will attend the movie "x". We know that 95% of these people have yet to arrive, which means that only 5% have already arrived.

We can set up an equation to represent this situation:

5% of x = 170

To solve for x, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 5% (or 0.05, which is the decimal equivalent of 5%):

5% of x / 5% = 170 / 5%

Simplifying the left side of the equation gives:

x = 170 / 0.05

Evaluating the right side of the equation gives:

x = 3400

Therefore, there were 3400 tickets sold for the movie.

Answer:

No statements are included in the question.  Several observations are noted.

Step-by-step explanation:

y = 6x + 2

y = 6x + 1

y=mx+b is the equation for a straight line, where m is the slope and b the y-intercept.  

Observations

1.  These are both straight lines.

2.  The slopes are both the same:  +6.  The lines are parallel.

3.  Since they are parallel, they will never intersect (within the solar system)

4.  The second line is one unit lower than the first:  it's y-intercept is +1, comapared to +2 for the first.

5.  Since they do not intercept, there is no solution for this system of equations.

These will likely match some of the statements.

The simplified expression is \(21x^2 - 25x - 28\) in the given case.

An expression in mathematics is a combination of numbers, symbols, and operators (such as +, -, x, ÷) that represents a mathematical phrase or idea. Expressions can be simple or complex, and they can contain variables, constants, and functions.

"Expression" generally refers to a combination of numbers, symbols, and/or operations that represents a mathematical, logical, or linguistic relationship or concept. The meaning of an expression depends on the context in which it is used, as well as the specific definitions and rules that apply to the symbols and operations involved. For example, in the expression "2 + 3", the plus sign represents addition and the meaning of the expression is "the sum of 2 and 3", which is equal to 5.

To simplify the expression, first distribute the -3x and (3x + 4) terms:

\(-3x(4 - 5x) + (3x + 4)(2x - 7) = -12x + 15x^2 + (6x^2 - 21x + 8x - 28)\)

Next, combine like terms:

\(-12x + 15x^2 + (6x^2 - 21x + 8x - 28) = 21x^2 - 25x - 28\)

Therefore, the simplified expression is \(21x^2 - 25x - 28.\)

The total number of students in the sixth grade is equal to 250.

Percent of students purchased their lunch = 24%

Number of students brought their lunch from home = 190

Let us call the total number of students in the 6th grade 'x'.

We know that all students either purchased their lunch or brought their lunch from home,

x = students who purchased their lunch + students who brought their lunch from home

24% of the students purchased their lunch, so the number of students who purchased their lunch is 0.24x.

And we know that 190 students brought their lunch from home.

Substituting these values into the equation above, we get,

x = 0.24x + 190

Solving for x, we can start by subtracting 0.24x from both sides,

⇒ 0.76x = 190

Then we divide both sides by 0.76 to isolate x,

x = 250

Therefore, there are 250 students in the 6th grade.

The area of the top surface of the wedge is approximately 9.97 square inches.

To find the area of the top surface of the wedge, we need to calculate the area of the corresponding sector of a circle.

The formula to calculate the area of a sector is:

Area = \((θ/2) * r^2\)

Where:

θ is the central angle (in radians)

r is the radius of the circle

In this case, the central angle is π/4 and the radius is 3 inches.

Plugging in the values into the formula:

Area =\((π/4 / 2) * (3 inches)^2\)

Simplifying:

Area = (π/8) * 9 square inches

Approximating the value of π to 3.14:

Area ≈ (3.14/8) * 9 square inches

Area ≈ 1.10775 * 9 square inches

Area ≈ 9.96975 square inches

Therefore, the area of the top surface of the wedge is approximately 9.97 square inches.

The optimal values of these parameters are:

a. β₁ = 0

b. β₂ = 0

The linear regression y = β1 + β2x + e, assuming that the sum of squared errors (SSE) takes the following form:

SSE = 382 + 681 + 382 + 18β1β2

Derive the partial derivatives of SSE with respect to β1 and β2 and solve the optimal values of these parameters.

Given that SSE = 382 + 681 + 382 + 18β1β2 ∂SSE/∂β1 = 0 ∂SSE/∂β2 = 0

Now, we need to find the partial derivative of SSE with respect to β1.

∂SSE/∂β1 = 0 + 0 + 0 + 18β2 ⇒ 18β2 = 0 ⇒ β2 = 0

Therefore, we obtain the optimal value of β2 as 0.

Now, we need to find the partial derivative of SSE with respect to β2. ∂SSE/∂β2 = 0 + 0 + 0 + 18β1 ⇒ 18β1 = 0 ⇒ β1 = 0

Therefore, we obtain the optimal value of β1 as 0. Hence, the partial derivative of SSE with respect to β1 is 18β2 and the partial derivative of SSE with respect to β2 is 18β1.

Thus, the optimal values of β1 and β2 are 0 and 0, respectively.

Therefore, the answers are: a. β₁ = 0 b. β₂ = 0

A figure which has four straight sides along with 4 right angles is called rectangle.  Two equal side lengths are parallel to each other, and the bigger sides are called length of rectangle and smaller sides are called breadth.

we can determine the height of rectangle by the following formula

if a rectangle has length, A and breadth, B

we know the area of rectangle is the product of length and breadth.

Area =A×B

we know the position of A is along the horizontal and position of B is along the vertical. Therefore, breadth, B refers the height of rectangle.

if we know the value of area and length we will find the height.

breadth = Area/length

height = Area/length

Answer:

We conclude that Tim is correct when he says that the expression x² only yields values that are positive.

Step-by-step explanation:

Given the expression

x²

Putting x = 1 in the expression

x²= (1)² = 1

Putting x = -1 in the expression

x²= (-1)² = 1

Thus, the expression yields the same output '1' when we enter x = 1, and x=-1.

Putting x = 2 in the expression

x²= (2)² = 4

Putting x = -1 in the expression

x²= (-2)² = 4

Thus, the expression yields the same output '4' when we enter x = 2, and x=-2.

Putting x = 3 in the expression

x²= (3)² = 9

Putting x = -1 in the expression

x²= (-3)² = 9

Thus, the expression yields the same output '9' when we enter x = 3, and x=-3.

The reason why the expression x² only yields positive values because the expression is in the square form, and the square of any number will always yield a positive value, no matter whether the input number is negative or positive.

Therefore, we conclude that Tim is correct when he says that the expression x² only yields values that are positive.
