Answer 1

The expansion of the polynomial (-p²+4p-3)(p²+2) would be is -p⁴ + 4p³ - 5p² + 8p - 6  

Here we need to expand the polynomial (-p²+4p-3)(p²+2)

To do so we need to multiply each of the term with the first bracketby the each term of second bracket.

So, the expansion of the polynomial (-p²+4p-3)(p²+2) would be,

(-p² + 4p - 3)(p² + 2)

= [p² × (-p² + 4p - 3)] + [2 × (-p² + 4p - 3)]

= [p² × (-p²) + p² × 4p - p² × 3] + (-2p² + 8p - 6)

= (-p⁴ + 4p³ - 3p²) + (-2p² + 8p - 6)

= -p⁴ + 4p³ - (3 + 2)p² + 8p - 6       .......(add like terms)

=  -p⁴ + 4p³ - 5p² + 8p - 6  

Therefore, the required polynomial is -p⁴ + 4p³ - 5p² + 8p - 6

Given matrix A: 3 vectors, each with 2 entries in each vector, this is considered 1 to 1. Is the linear transformation​ onto?

Answers

The matrix A or the linear transformation it represents to determine whether the transformation is onto or not.

We cannot determine whether the linear transformation given by matrix A is onto based solely on the information provided about the matrix A.

Recall that a linear transformation is onto if and only if its range is equal to its codomain.

In other words, for every vector b in the codomain, there exists at least one vector x in the domain such that [tex]T(x) = b[/tex], where T is the linear transformation.

If A is a matrix representing a linear transformation from[tex]R^2[/tex] to[tex]R^3[/tex], then the codomain is[tex]R^3[/tex], and the range of the transformation is a subspace of [tex]R^3[/tex].

If the matrix A is 1-to-1, then its nullspace only contains the zero vector. This implies that the columns of A are linearly independent, which means that the column space of A has dimension 2.

The range of the transformation has dimension at most 2.

The codomain has dimension 3, it is possible for the range to be a proper subspace of the codomain, in which case the transformation would not be onto.

Find the area, in square inches, of the composite figure.
12 in.

3 in.
3 in.
25 in.

Answers

The area, in square inches, of the composite figure is: 112.125 square inches.

How to obtain the area

To obtain the area in square inches of the composite figure, we can start by calculating the area of the rectangle to be

= length x width = 14 x 2

= 28 square inches

The leg length of 25 will be divided by 2 to give 12.5. Next we find the area of the isosceles right triangle as follows:

= (leg length)^2 / 2 = (12.5)^2 / 2 = 78.125 square inches.

The combined area = Area of rectangle + Area of isosceles right triangle

= 28 + 78.125

= 106.125 square inches

So, the area of isosceles triangle = (base x height) / 2

= (4 x 3) / 2

= 6 square inches

Now we can add up the areas of the individual shapes to find the total area of the composite figure:

Total area = Combined area + Area of isosceles triangle

= 106.125 + 6

= 112.125 square inches

Complete Question:

Find the area, in square inches, of the composite figure. A composite figure consisting of an isosceles right triangle, a rectangle, and an another isosceles triangle. The combined length of the right triangle and the rectangle is 25 inches. The length of only the rectangle is 14 inches.

A television producer designs a program that will include a comedian and

time for commercials. The advertiser insists on at least 2 minutes of

advertising time. The station insists on no more than 4 minutes of

advertising time and the comedian insists on at least 24 minutes of the

comedy program. The total time allotted for the advertising and comedy

portion cannot exceed 30 minutes. If it has been determined that each minute

of advertising (very creative advertising) attracts 40,000 viewers and each

minute of comedy time attracts 45,000 viewers, how should the time be

divided between advertising and the comedy program in order to maximize

the number of viewers?

Answers

According to the concept of inequality, the maximum value of A is obtained when a = 2 and c = 28.

Let's assume that each minute of advertising attracts 40,000 viewers and each minute of comedy attracts 45,000 viewers. Therefore, the total audience (in thousands) that can be reached is given by:

A = 40a + 45c

Firstly, we know that the total time allotted for advertising and comedy cannot exceed 30 minutes. Therefore, we can rewrite the inequality as:

a + c ≤ 30

Solving for c, we get:

c ≤ 30 - a

Now, we can substitute this expression for c in the equation for A:

A = 40a + 45c

A = 40a + 45(30 - a)

A = 1350 - 5a

To maximize A, we need to find the value of a that will result in the maximum value of A. Taking the derivative of A with respect to a and setting it equal to zero, we get:

dA/da = -5 = 0

a = 0

This does not make sense, as a cannot be zero. Therefore, we need to check the endpoints of the interval [2,4] to see if they give a maximum value for A.

When a = 2, we get:

A = 40(2) + 45c

A = 80 + 45c

Substituting c = 30 - a, we get:

A = 80 + 45(30 - 2)

A = 80 + 1350

A = 1430

When a = 4, we get:

A = 40(4) + 45c

A = 160 + 45c

Substituting c = 30 - a, we get:

A = 160 + 45(30 - 4)

A = 160 + 1215

A = 1375

This means that the producer should allocate 2 minutes for advertising and 28 minutes for the comedy program in order to maximize the number of viewers.

Answers

Thus, the value of the  x- and y-intercepts for the given linear equation is (-30, 0) and (0, 15)

Explain about the x- and y-intercepts:

A nonlinear function's intercepts can be defined algebraically or graphically. The points on a graph where a nonlinear function crosses both x and y axes are known as the intercepts.

The terms "y-intercept" and "x-intercept" both refer to the values at the places where the graph crosses the y-axis and the x-axis, respectively.Keep in mind that x is zero at the y-intercept and y is zero at the x-intercept. According to algebra, a function's y-intercept is its value when x equals zero, and its x-intercept is its value when y equals zero.

Given that-

linear equation:  -x + 2y = 30

x-intercept: It occurs when y = 0,

-x + 2(0) = 30

-x = 30

x = -30

y-intercept: It occurs when x = 0,

-0 + 2y = 30

The null and alternative hypotheses divide all possibilities into: Question 10 options: two sets that overlap two non-overlapping sets as many sets as necessary to cover all possibilities two sets that may or may not overlap

Answers

The null hypothesis represents the default assumption or the status quo, while the alternative hypothesis represents the alternative possibility or the hypothesis that is being tested.

These two hypotheses are mutually exclusive, meaning that if one is true, the other must be false.

The null and alternative hypotheses divide all possibilities into two non-overlapping sets.

In statistical hypothesis testing, the null and alternative hypotheses divide all possibilities into two non-overlapping sets.

These two hypotheses represent different explanations or theories about the data, and they are used to make inferences about the population from the sample data.

The null hypothesis represents the default assumption or the status quo. It states that there is no significant difference or relationship between two variables, or that the observed data is due to random chance alone. The alternative hypothesis, on the other hand, represents an alternative explanation or theory about the data.

It states that there is a significant difference or relationship between two variables, or that the observed data is not due to random chance alone.

The null and alternative hypotheses are mutually exclusive, meaning that if one hypothesis is true, the other hypothesis must be false.

They are also exhaustive, meaning that they cover all possible explanations for the observed data.

By dividing all possibilities into two non-overlapping sets, the null and alternative hypotheses allow us to make a decision about which hypothesis is more likely to be true based on the evidence provided by the sample data.

In order to test the null and alternative hypotheses, we use statistical methods to calculate the probability of obtaining the observed data if the null hypothesis were true.

This probability is called the p-value, and it represents the likelihood of obtaining the observed data or a more extreme result if there were no true effect or relationship in the population.

If the p-value is small enough, we reject the null hypothesis in favor of the alternative hypothesis.

The null and alternative hypotheses divide all possibilities into two non-overlapping sets and provide a framework for making inferences about the population based on sample data.

By testing the null hypothesis and calculating the p-value, we can make decisions about which hypothesis is more likely to be true based on the evidence provided by the sample data.

In statistical hypothesis testing, we use evidence from the data to decide whether to reject the null hypothesis in favor of the alternative hypothesis or not.

Julie rents bicycles in a tourist town. The table shows how many of each type of bicycle Julie rented over the
weekend and the money she received from the rentals. Determine the cost to rent each kind of bicycle.

Answers

Answer: Since we don't have the actual table, we can't provide an exact answer. However, we can explain the general method for solving this type of problem.

Let's say that Julie rented three types of bicycles: type A, type B, and type C. Let's also say that she rented a certain number of each type, and received a certain amount of money from each type. We can set up the following equations based on this information:

Cost to rent type A bike = (Amount received for type A rentals) / (Number of type A bikes rented)

Cost to rent type B bike = (Amount received for type B rentals) / (Number of type B bikes rented)

Cost to rent type C bike = (Amount received for type C rentals) / (Number of type C bikes rented)

We can then solve for each cost by plugging in the given numbers from the table. For example, if the table shows that Julie rented 10 type A bikes and received $200 in rental fees, we would have:

Cost to rent type A bike = $200 / 10 = $20

We can do this for each type of bike to find the cost to rent each kind of bicycle.

It's worth noting that the actual equations may look slightly different depending on the specific information provided in the table. For example, if the table gives the total number of bikes rented and the total amount received, we would need to use slightly different equations to solve for the individual costs.

Answers

The width of the path is 24 meters.

How to calculate the width

Let's call the width of the path "x".

The dimensions of the inner rectangle (the lawn without the path) are 46m by 34m. The dimensions of the outer rectangle (the lawn with the path) are (46+2x) by (34+2x).

Area of path = Area of outer rectangle - Area of inner rectangle

425m² = (46+2x)(34+2x) - (46)(34)

Simplifying and solving for x:

425m² = (2x+46)(2x+34)

425m² = 4x² + 80x + 1564

A "Trapezium" is defined as a polygon with "four-sides", where one pair of opposite sides are parallel and the other pair of opposite sides are non-parallel.

Let point "M" be on AD, So, Height = 6 cm ⇒ BM = 6 cm,

We Apply Pythagoras-Theorem in Triangle AMB,

So, AM² = AB² - BM²

⇒ AM² = (7.5)²- (6)²,

⇒ AM  = 4.5,

Let "N" be a point on "AD", such that "CN ⊥ AD",

So, the base AD will be =  AM +  MN + ND,

MN = BC = 10 and CN = BM = 6 (height)

⇒ 24 = 4.5 + 10 + ND,

⇒ ND = 9.5

In triangle-CDN, Tan(∠CDN) = CN/ND,

From the figure , we see that, ∠CDN = ∠CDA,

[tex]sin(x) = \cos(\frac{\pi}{2} - x) \\ \tan(x) = \cot(\frac{\pi}{2} - x) \\ \sec(x) = \csc(\frac{\pi}{2} - x) \\ \cos(x) = \sin(\frac{\pi}{2} - x) \\ \cot(x) = \tan(\frac{\pi}{2} - x) \\ \csc(x) = \sec(\frac{\pi}{2} - x)[/tex]

what is the total amount of water that Kiesha drinks during the 12 days

Answers

The total amount of water Keisha drinks in 12 days is 12 + 18 = 30 quarts.

Describe Algebra?

Algebra is a branch of mathematics that involves using letters and symbols to represent numbers and quantities in mathematical equations and formulas. It includes a variety of topics, such as solving equations, manipulating expressions, working with functions and graphs, and studying abstract structures such as groups and rings.

At its core, algebra is about understanding the relationships between numbers and how they can be manipulated using various operations such as addition, subtraction, multiplication, and division. Algebraic expressions can be used to model real-world situations and solve problems in fields such as physics, engineering, and finance.

To find the total amount of water Keisha drinks in 12 days, we need to add up the amounts of water she drinks each day:

1 1/2 + 2 1/4 + 2 + 1 1/2 + 1 3/4 + 1 1/2 + 1 1/4 + 2 + 2 1/4 + 1 1/2 + 2 + 1 1/2

We can simplify the mixed numbers by converting them to improper fractions:

3/2 + 9/4 + 2 + 3/2 + 7/4 + 3/2 + 5/4 + 2 + 9/4 + 3/2 + 2 + 3/2

Then we can add the fractions together:

(3/2 + 3/2 + 3/2 + 2 + 2 + 2) + (9/4 + 7/4 + 5/4 + 9/4 + 3/2 + 3/2)

Simplifying the sum of the whole numbers, we get:

12

Simplifying the sum of the fractions, we get:

The profit of a business is described by the function P(x)=-3x^2+12x+75, where x is the number of items made, in thousands, and P(x) is the profit in dollars. How many items will maximize the profit?

Answers

The maximum profit will be $87,000.

How to find the vertex of the parabola?

To find the quantity of things that will augment the benefit, we want to find the vertex of the parabola addressed by the given capability.

The vertex of a parabola in the form of[tex]y = ax^2 + bx + c[/tex] is located at the point [tex](-b/2a, c - b^2/4a)[/tex].

So for the function [tex]P(x) = -3x^2 + 12x + 75,[/tex] the coefficient of [tex]x^2[/tex] is -3, the coefficient of x is 12, and the constant term is 75.

Therefore, the number of items that will maximize the profit is:

x = -b/2a = -12 / 2(-3) = 2

The second derivative test is something we can use to make sure that this is a maximum. The vertex is a maximum when the second derivative of P(x) is -6, which is negative.

Since x is in thousands, the maximum profit occurs when 2,000 items are produced, and the maximum profit is:

[tex]P(2) = -3(2)^2 + 12(2) + 75 = 87[/tex]

Hence, the business will boost its benefit by making 2,000 things, and the most extreme benefit will be $87,000.

5 cm
LA = [?]π cm²
Hint: Lateral Area of a Cone = Tre
Where & slant height

Answers

The lateral surface-area of the cone with dimensions 12 cm height and 5 cm radius is 65π cm² using the formula πrl.

What is surface-area?

The overall surface area of a solid shape, item, or three-dimensional figure.It can have a flat or curved surface. Cone and cylinder surfaces are curved, but those of solid structures like the cube and cuboid have flat surfaces. The surface area of the cube is provided by 6 times side times side, which equals the area of each face side times side. The cube and cuboid have 6 faces, 12 equal edges, and 8 corners or vertices.

Given that the dimensions of cone:

Radius(r)=5 cm

Height(h) = 12 cm

slant height l =[tex]\sqrt{r^{2} +h^{2} }[/tex]

                      =[tex]\sqrt{(5)^{2} +(12)^{2} }[/tex]

                      =[tex]\sqrt{25+144}[/tex]

                      =[tex]\sqrt{169}[/tex]

                      =13 cm

Slant height (l) = 13 cm

lateral area of cone= πrl.

                                =π (5) (13)

The volume of  the solid is 761.97 in².

The mistake the student made is that the student did not subtract the square of the radius of the inner hollow cylinder  from the square of the radius of the main cylinder.

How to find the volume of the solid?

The volume of the solid can be found by adding the volume of hollow cylinder and the volume of the cone. That is:

Volume of solid = volume of hollow cylinder + volume of the cone

Volume of solid = π(R²-r²)H + 1/3πR²h

where R = 8/2 = 4 in, r = 2 in, H = 18 in and h = 5 in

Volume of solid = [3.14 * (4²-2²) * 18] + [1/3 * 3.14 * 4² * 5]

Volume of solid = 678.24 + 83.73

Volume of solid = 761.97 in²

The mistake the student made is that the student did not subtract the square of the radius of the inner hollow cylinder  from the square of the radius of the main cylinder.

The Culver City Carnival had a face-painting booth. There were 8 times as many kids as adults who had their faces painted.
If 56 kids had their faces painted, how many people had their faces painted altogether?

Answers

Answer:

Step-by-step explanation:

Let X be the number of adults who had their faces painted.

Therefore, the number of kids who had their faces painted is 8*X.

Given that 56 kids had their faces painted, we can write an equation as:

8*X = 56

Solving for X:

X = 7

So, there were 7 adults who had their faces painted and 56 kids who had their faces painted.

Altogether, there were 7 + 56 = 63 people who had their faces painted.

Solve x2−−√=x . A. all values of x B. all values of x l x ≥ 1 C. all values of x l x ≥ 0 D. all values of x l x ≤ 0

Answers

The solution of the expression is x = (-1 ± i√3)/2 and the domain of the expression is all values of x l x ≥ 0 (option c).

The given equation is -x² = √x. To solve this equation, we need to isolate x on one side of the equation. We begin by squaring both sides of the equation to eliminate the radical:

(-x²)² = (√x)²

x⁴ = x

Now we have a quartic equation, which we can solve by factoring:

x(x³ - 1) = 0

We can further simplify this equation by factoring the cubic term using the difference of cubes formula:

x(x - 1)(x² + x + 1) = 0

From this factorization, we can see that the solutions are x = 0, x = 1, and the solutions of the quadratic factor x² + x + 1 = 0. To find the solutions of the quadratic, we can use the quadratic formula:

x = (-1 ± √1 - 4(1)(1))/2(1)

x = (-1 ± i√3)/2

Therefore, the solutions to the equation -x² = √x are x = 0, x = 1, and x = (-1 ± i√3)/2.

Now let's consider the domain of the solutions, which is determined by the inequality x ≥ 0. This inequality means that the solutions must be greater than or equal to 0. We can see that x = 0 and x = 1 satisfy this inequality.

For the solution x = (-1 ± i√3)/2, we can see that it does not satisfy the inequality x ≥ 0 because it is negative. Therefore, the solutions to the equation -x² = √x in the domain x ≥ 0 are x = 0 and x = 1.

Finally, let's consider the inequality x ≤ 0. This inequality means that the solutions must be less than or equal to 0. We can see that x = 0 satisfies this inequality. However, x = 1 and x = (-1 ± i√3)/2 do not satisfy this inequality. Therefore, the solutions to the equation -x² = √x in the domain x ≤ 0 are x = 0.

Hence the correct option is (c).

which of the following numbers could be added to 1/12 to make us some greater than 1/2



5/12

9/24

1/3

4/9

Answers

The numbers that could be added to 1/12 to make the sum greater than 1/2 are 9/24 and 4/9.

To make the sum greater than 1/2, we need to find the number that, when added to 1/12, gives a result greater than 1/2.

1/2 is the same as 6/12, so we need to find the number that, when added to 1/12, gives a result greater than 6/12.

1/12 + 5/12 = 6/12, which is not greater than 1/2.

1/12 + 9/24 = 1/12 + 3/8 = 11/24, which is greater than 1/2.

1/12 + 1/3 = 1/12 + 4/12 = 5/12, which is not greater than 1/2.

1/12 + 4/9 = 3/36 + 16/36 = 19/36, which is greater than 1/2.

Therefore, the numbers that could be added to 1/12 to make the sum greater than 1/2 are 9/24 and 4/9.
