Use interval notation to express the following: The set of all numbers greater than −10 and less than −3.

Using the Pythagorean theorem we know that the rest 2 sides of the given right triangle are 27 inches long.

The longest side of a right-angled triangle, or the side opposite the right angle, is known as the hypotenuse in geometry.

The Pythagorean theorem, which asserts that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides, can be used to determine the length of the hypotenuse.

The side opposite the right angle is always the hypotenuse of a right triangle. In a right triangle, it is the longest side.

So, we know the Pythagorean theorem which is:

H² = a² + b²

We know that:

H² = a² + b²

54² = a² + b²

Suppose that the given right triangle is also an isosceles triangle with the rest of the sides being of the same length. Then,

54/2 = 27

Similarly,

54² = a² + b²

54² = 27² + 27²

Therefore, using the Pythagorean theorem we know that the rest 2 sides of the given right triangle are 27 inches long.

The square root of 45 lies between the two whole numbers 36 and 49.

Number is a mathematical object used to count, measure, and label. It is an abstract concept that can be represented in various forms, such as a numeral, a word, or an image. Numbers can be used to represent any quantity, such as a person's age, a distance, a temperature, or a length. They can also be used to represent abstract or intangible concepts, such as a feeling or a thought.

To determine this, we can use a process called the square root algorithm. The first step is to find the largest perfect square that is less than the number you are taking the square root of. In this case, that would be 36. Then, you subtract that perfect square from your number. In this case, you would subtract 36 from 45, leaving you with 9. The next step is to find the two whole numbers that the square root of this difference lies between. Since 9 is the square root of 81, the two numbers that the square root of 9 lies between are 3 and 4. Therefore, the square root of 45 lies between the two whole numbers 36 and 49.

Step-by-step explanation:

Given cos, you will have to use this to calculate sin because csc is  1/ sin

Remember    cos^2 + sin^2 = 1

                        (2/5)^2 + sin^2 = 1

                                  sin^2 = 21/25  

                                    sin = sqrt (21) / 5     (ignoring negative root)

csc = 1/sin = 5 / sqrt(21)

The response to the given question would be that Because it has a interest higher interest rate and a longer term than option 3, option 1 would generate the greatest interest.

By dividing the principal by the interest rate, the passage of time, and other factors, simple interest is determined. Simple return equals principle plus interest plus hours is the formula used in marketing. The easiest way to compute interest is by using this method. The most typical method for calculating interest is as a portion of the principle amount. For example, if he borrows $100 from a buddy and agrees to pay back the loan at 5% interest, he will only pay his share of the 100% interest. $100 (0.05) = $5. When you borrow money, you must pay interest, and you must charge interest when you lend it. Typically, interest is determined as an annual percentage of the loan total. The interest rate of the loan is defined as this ratio.

The following would be the order of 2000 simple interest generated on an investment, from least to most:

2000 invested for 20 years at 3% simple interest

2000 invested for three years at 10% simple interest

2000 invested at 10% simple interest for nine years

Because of its longer length and lower interest rate than the other two alternatives, Option 2 would yield the least amount of interest.

Due to its higher interest rate and longer period, option 3 would generate more interest than option 2.

Because it has a higher interest rate and a longer term than option 3, option 1 would generate the greatest interest.

Using a standard normal distribution table, the value of z₀ is -0.64

To find z₀, we need to use the standard normal distribution table or calculator. We know that the area under the standard normal curve between z₀ and 2.2 is 0.7258.

Using a standard normal distribution table or calculator, we can find the z-score corresponding to 0.7258.

From the table, we can find that the closest value to 0.7258 is 0.7257, and the corresponding z-score is approximately 0.61.

Therefore, we have:

P(z₀ < z < 2.2) = 0.7258

P(z < 2.2) - P(z < z₀) = 0.7258

Using the z-score table again, we can find that P(z < 2.2) is approximately 0.9861.

So we have:

0.9861 - P(z < z₀) = 0.7258

P(z < z₀) = 0.2603

Using the z-score table again, we can find that the z-score corresponding to 0.2603 is approximately -0.64.

Therefore, we have:

z₀ = -0.64

Rounding to at least four decimal places, we get:

z₀ = -0.6400

Tahlia was correct in remembering that you can find the slope of a line using the slope formula.

She was also correct that the slope is 0.5.

However, if you use the slope-intercept formula y = mx + b, you still have to find b (the y-intercept) by plugging in one of the two points and the slope.

So, if we plug in the first point and the slope into the line, we can find b and thus the full equation of the line:

The key features of the parabola include the following:

A) opens down

C) directrix at y = 1/8

D) vertex at (-1/2, 0).

Mathematically, the standard equation of the directrix lines for any parabola is given by this mathematical expression:

y = a(x - h)² + k.

Where:

Based on the information provided about the parabola, we have:

4x^2 + 4x + 2y + 1 = 0

2(y + 1/2) = -4(x + 1/2)^2 + 1

(y + 1/2) = -2(x + 1/2)^2 + 1/2

By comparing to the standard form, we have:

Vertex, (h, k) = (-1/2, 0).

Additionally, the distance between the vertex and the directrix is given by:

y = |1/(4a)|

y = |1/(4 × -2)|

y = |-1/8|

y = 1/8.

We simplify the summation to get:

S₄ = 8*(3ⁿ⁻¹)

Remember that the large sigma means that we need to add from the lower number to the larger number.

The particular problem here is that "n" is not the index in the summation, so we can't evaluate that variable, we will just have 4 terms (for k = 1 to k = 4) but the variable k does not appear, so we will  have 4 times the same term:

S₄ = 2*(3ⁿ⁻¹) +  2*(3ⁿ⁻¹) +  2*(3ⁿ⁻¹) +  2*(3ⁿ⁻¹)

The inequality 2d+20<=120 is a valid inequality. It means that some value of d can be substituted into the inequality to make it a true statement.

In mathematics, an inequality is a statement that compares two values and indicates how they are related in terms of magnitude or size. Inequalities use symbols such as "<" (less than), ">" (greater than), "<=" (less than or equal to), ">=" (greater than or equal to), or "≠" (not equal to) to show the relationship between the two values.

In the given question,

Yes, the inequality 2d+20<=120 is a valid inequality. It means that some value of d can be substituted into the inequality to make it a true statement.

In this case, the inequality is saying that 2 times the value of d plus 20 is less than or equal to 120. To solve for d, we can subtract 20 from both sides to get:

2d <= 100

Then, we can divide both sides by 2 to isolate d:

d <= 50

So the solution to the inequality is that d must be less than or equal to 50 for the inequality to be true.

Step-by-step explanation:

The total number of cars that will fit in the spaces at school is less than or equal to 155, which means that the combined number of parking spaces in the parking lot and on the side of the building cannot exceed 155.

What is expression ?

In mathematics, an expression is a combination of numbers, variables, and operators (such as addition, subtraction, multiplication, and division) that represents a quantity or a relationship between quantities. Expressions can be as simple as a single number or variable, or they can be complex, involving multiple variables and operations.

Let x be the number of parking spaces in each row of the school parking lot. Then, the total number of parking spaces in the parking lot is 6x.

The total number of parking spaces in the school is the sum of parking spaces in the parking lot and parking spaces on the side of the building, which is 6x + 35.

Since the total number of cars that will fit in the spaces at school is at most 155, we can write the inequality:

6x + 35 ≤ 155

Simplifying this inequality, we get:

6x ≤ 120

x ≤ 20

Therefore, the total number of cars that will fit in the spaces at school is less than or equal to 155, which means that the combined number of parking spaces in the parking lot and on the side of the building cannot exceed 155.

One hot wing costs 60 cents at this restaurant.

A variable in an equation that has to be solved for is known as an unknown.

A polynomial or formal power series may contain an indeterminate symbol, often known as a variable. In the polynomial ring or the ring of formal power series, an indeterminate is a constant rather than a variable. Nonetheless, many writers view indeterminates as a distinct class of variables because of the close connection between polynomials or power series and the functions that they describe.

Let's us assume that the cost of one hot wing is x dollars.

Then,

Total amount spent by each customer:

8x + 4 = 10x + 2.8

8x - 10x = 2.8 - 4

Answer:

The heaviest piece of chocolate weighed 2.94 ounces.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let's call the number of gallons of gas consumed by the first car "x" and the number of gallons of gas consumed by the second car "y". We can set up a system of two equations to represent the information given in the problem:

x + y = 45 (equation 1: total gas consumption is 45 gallons)

35x + 25y = 1375 (equation 2: total distance traveled is 1375 miles)

To solve for x and y, we can use the first equation to solve for one variable in terms of the other. For example, we can solve for y as:

y = 45 - x

We can then substitute this expression for y into the second equation, and simplify:

35x + 25(45 - x) = 1375

35x + 1125 - 25x = 1375

10x = 250

x = 25

So the first car consumed 25 gallons of gas that week. We can substitute this value into equation 1 to find the number of gallons consumed by the second car:

25 + y = 45

y = 20

Therefore, the second car consumed 20 gallons of gas that week.
