Answer:

she is 0 blocks away from home because you said she started at home

Answer:

a) Malavika is 8 blocks west from home

b) Traveled 20 blocks total

Step-by-step explanation:

a) According to a compass: 3 west (left), then 6 east (right) and that puts you at 3 east (right). Then back 11 west (left) puts you at 8 west (left)

b) Add up all blocks traveled: 3 + 6 + 11 = 20

The area of the rectangle is A = 172.5 m^2

The area of a rectangle can be found by using the formula A = lw, where l is the length and w is the width. In this case, we are given that the length is 8 meters more than twice the width, so we can let l = 2w + 8. We are also given the perimeter, which is the sum of the length and width multiplied by two, or 2l + 2w. We can set this equal to 46 and solve for w:

2(2w + 8) + 2w = 46

4w + 16 = 46

4w = 30

w = 7.5

Therefore, the width of the rectangle is 7.5 meters and the length is 2(7.5) + 8 = 23 meters. The area of the rectangle can then be found by substituting these values into the area formula:

A = lw

A = (23)(7.5)

A = 172.5 m^2

The incorrect code contained two errors. The first was that the variable 'resistance' was initialized with a string value from the prompt, and the second was that the inverse value was not rounded off to two decimal places.

// incorrect code

//

// let resistance = prompt("Enter the resistance: ");

// inverse = 1.0 / resistance;

// console.log("The inverse of resistance is " + inverse);

// correct code

let resistance = parseFloat(prompt("Enter the resistance: "));

let inverse = 1.0 / resistance;

console.log("The inverse of resistance is " + inverse.toFixed(2));

1. In the incorrect code we have a variable 'resistance' that is initialized with a string value from the prompt. To fix this we have used the parseFloat function to convert this string to a float value.

2. In the incorrect code the inverse value is not rounded off to 2 decimal places. To do this we have used the toFixed(2) method to round off the inverse value to 2 decimal places.

A specific example of a non-representative sample can be seen in the 2016 US presidential election.

The national polls indicated that Hilary Clinton had a lead in the polls, but Donald Trump went on to win the election. This is because the sample used in the polls was not representative of the population. The sample was disproportionately composed of college-educated individuals, when the actual electorate was more evenly balanced between college-educated and non-college-educated individuals. This caused the samples to be biased and not representative of the population.

For example, if we assume that the population is composed of 50% college-educated individuals and 50% non-college-educated individuals, then the sample should also be composed of 50% college-educated individuals and 50% non-college-educated individuals to be representative. If the sample is not composed of 50% college-educated individuals and 50% non-college-educated individuals, then the sample is not representative of the population.

This can be calculated by using the formula: (Number of College Educated Individuals in Sample/Total Sample Size) X 100.

For example, if the sample size is 100 and there are 75 college-educated individuals in the sample, then the sample is not representative of the population because (75/100) X 100 = 75%, which is not equal to the 50% of the population that is college-educated.

The total distance traveled by the particle over 5 units of time is 140 units.

What is the total distance?

To find the total distance a particle travels over a certain time interval, we need to find the definite integral of its velocity function over that interval. The velocity function is the derivative of the position function.

In this case, the position function of the particle is x(t) = t³ - 6t + 9t - 2 and we need to find the total distance traveled by the particle over 5 units of time.

The velocity function is x'(t) = 3t² - 6 + 9 = 3t² + 3

The total distance traveled over 5 units of time is the definite integral of the velocity function evaluated between 0 and 5.

∫(3t²+3) dt from 0 to 5

= [t³ + 3t] from 0 to 5

= (5³ + 3*5) - (0 + 0) = 125 + 15 = 140

In both cases, your answer choice copy/paste messed up the formatting. I looked at the coefficients and came up with the choices.

You should compare the actual terms with the choices I have provided to make sure they match

Step-by-step explanation:

The two polynomials are
2x² + 3x - 6

and

Addition

To add these two polynomials together group like terms and add their coefficients:

(2x² + 3x - 6) + (x² - 4x + 2)

= 2x² + 3x - 6 + x² - 4x + 2

= (2x² + x²) + (3x -4x) + (-6 + 2)

= 3x² - x - 4

Your answer choices have lost formatting during copy paste. You will have to compare and choose the right one. I think it is C because it has a 3x² term and the last term is - 4

Answer:

To solve the equation 9x² = 3³x-2, we can follow these steps:

First, we need to simplify the right side of the equation. 3³ = 27, so we can replace 3³ with 27. The equation now becomes: 9x² = 27x - 2

Next, we'll want to get all the x terms on one side of the equation and all the constants on the other side. To do this, we'll add 2 to both sides of the equation: 9x² = 27x - 2 + 2 = 27x. This gives us: 9x² = 27x

Next, we'll divide both sides of the equation by 9. This will give us x² = 3x.

Finally, we can divide both sides by 3. This will give us x = 1.

So the solution is x = 1

The general statement for the previous question is that if a homogeneous system of equations has at least one non-zero solution, then it has infinitely many solutions, which can be found by taking multiples of the non-zero solution.

(a) (i)

Let p = (1,3,4) and q = (5,8,12) be two points in R3. The line joining p and q can be written as lq + (1-\p) where l is a real number. By substituting in the coordinates of p and q, we get l(5,8,12) + (1-\1,3,4) = (l + 1-\, l+3-\, l+4-\). This is the equation for the line joining p and q, where l can be any real number.

(ii)

To check that all points on the line joining p and q are also solutions to the system of linear equations, we substitute the equation of the line into the system of equations.

01111 + 212.22 + 213.43 = 21

(l + 1-\) + 2(l+3-\) + 3(l+4-\) = 21

Simplifying, this gives: l + 6 - \ = 21. Therefore, all points on the line joining p and q are solutions to the system.

(b)

To check that any multiple of p, i.e., a vector of the form (1,3,4) where is any real number, is also a solution of the system, we substitute the equation of the multiple of p into the system.

01111 + 212.22 + 213.23 = 0

(l + 1-\) + 2(l+3-\) + 3(l+4-\) = 0

Simplifying, this gives: l + 6 - \ = 0. Therefore, all multiples of p are solutions to the system.

$1.15

Let's call the cost of the bike horn "x".

Dirk paid $5.33 and received $4.18 in change, so he must have paid x + $4.18 = $5.33.

Solving for x, we get x = $5.33 - $4.18 = $1.15.

Therefore, the bike horn cost $1.15.

The solution of the system of equations is:

(-3/2, 1/2)

Here we have two lines of the form:

y = a*x + b

one passes through (0, 0) and (1, -3)

For the first point we know that the constant is 0, and replacing the values of the second point we get:

1 = a*-3

1/-3 = a

The line is:

y = (-1/3)*x

The second line passes through (0, 2) and (-1, 1) from the first point we can see that:

y = a*x + 2

And replacing the values of the second point we get:

1 = a*-1 + 2

1 - 2 = -a

-1 = - a

1 = a

This line is y = x + 2

Then the system of equations is:

y = x + 2

y = (-1/3)*x

We can replace use the substitution method to write:

x + 2 =  (-1/3)*x

x + 1/3*x = -2

(4/3)*x = -2

x = -2*(3/4)

The bar diagram representing 150% of the price 5 years ago would be a bar with a height of $4.50.

What is the percentage?

Percentage is a way to express a number as a fraction of 100. It is often used to describe the relationship between two quantities, or to express a rate or change in a quantity over time. The symbol for percent is "%".

For example, if a pizza is marked up by 20%, it means the price has increased by 20/100 or 1/5 of the original price. If a student scores 80% on a test, it means they got 80 out of 100 questions correct. If a stock's value increases by 10%, it means the value has gone up by 10/100 or 1/10 of the original value.

The current admission price is $3 + $3 * 50% = $3 + $1.50 = $4.50.

150% of the price 5 years ago is $3 * 150% = $3 * 1.5 = $4.50.

So, the bar diagram representing 150% of the price 5 years ago would be a bar with a height of $4.50.

For equation 1, substitution x=4tanθ is the most helpful. For 2, substitution x=4sinθ is the most helpful. For 3, substitution x=4secθ is the most helpful. For 4, substitution x=4sinθ is the most helpful. For 5, substitution x=4tanθ is the most helpful.

Substitutions are often used to simplify indefinite integrals. For example, in the first integral ∫√(x^2-16) dx, substitution x=4tanθ is the most helpful. This is because it will allow us to simplify the expression under the radical. After substituting, we have ∫√(16tan^2θ-16) dθ. The 16tan^2θ can be factored to give 16(tan^2θ-1), which is equal to 16sec^2θ-16. This simplifies the integral, making it easier to integrate. In a similar way, substitution can also be used to simplify the other integrals. For example, for the fourth integral ∫(x^2 – 16)^(5/2) dx, substitution x=4sinθ is the most helpful. After substituting, we have ∫(16sin^2θ-16)^(5/2) dθ. This simplifies the integral, making it easier to integrate. In general, the substitutions chosen for each integral should be the ones that simplify the expression the most, allowing for easier integration.

The interval over which the function is continuous equation is (-∞, 3) U (3, +∞).

The function f(x) = (x2 - 5x - 6)/(x - 3) is continuous over all real numbers except x = 3, since the denominator is equal to 0 at x = 3.

We can use the properties of combinations of continuous functions to determine the interval(s) over which the function f(x) is continuous equation.

First, we need to consider the function f(x) in two parts. The first part is f(x) when x ≠ 3, and the second part is when x = 3.

For the first part, when x ≠ 3, the function f(x) is continuous over all real numbers, since both the numerator and denominator are continuous over all real numbers.

For the second part, when x = 3, the function f(x) is discontinuous, since the denominator is equal to 0.

Therefore, the interval over which the function f(x) is continuous is (-∞, 3) U (3, +∞).

A 4/4 time signature does not imply that each measure contains simply four quarter notes. It signifies that each measure only contains four beats. These beats may comprise half notes, quarter notes, eighth notes, pauses, or whatever the composer desires, but all note and rest values must add up to no more or less than the time signature’s top number (or numerator).

The most popular musical meter is 4/4. Because it is so widespread, it is also known as common time, and the two numerals in the time signature are sometimes substituted with the letter C.
