Answer:

76

Step-by-step explanation:

The discriminant of a quadratic equation of form ax^2 + bx + c = 0 is given by the expression b^2 - 4ac. In the given equation 3x^2 - 10x = -2, we can rewrite it in the standard form of a quadratic equation by adding 2 to both sides:

3x^2 - 10x + 2 = 0

a = 3, b = -10, and c = 2

We use the formula for the discriminant:

b^2 - 4ac = (-10)^2 - 4(3)(2) = 100 - 24 = 76

So, the answer is 76

The coordinate of B is (1,-3)

In coordinate system mid point is the point which is exactly at the middle

The coordinates of point A are (5,1)

The coordinate of  mid point M are (3,-1)

It is to be noted that mid point divides both sides in the ratio 1:1

We are required to find the coordinates of point B

Let the coordinates of B be (x,y)

For mid points, section  formula further simplifies to

m's x coordinate= (a's x coordinate + b's x coordinate)/2

m's y coordinate = (a's y coordinate + b's y coordinate)/2

therefore,

3 = (5+x)/2

6=5+x

x=6-5 =1

-1 = (1+y)/2

-2 =1+y

y=-3

Hence the coordinates of B are (x,y) which is (1,-3)

According to the given information, your share of the groceries was $39.95, your other roommate's share was $42.05, and Sarah's share was $0.

What is equation?

An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides separated by an equals sign (=). The expressions on both sides of the equation can contain numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division.

Let's call the amount of money Sarah spent on groceries "S".

Let's call the amount of money you spent on groceries "Y".

Let's call the amount of money your other roommate spent on groceries "O".

We know that:

S + Y + O = 82 (the total bill was $82)

Y = (S/2) - 0.05 (your groceries were $0.05 cheaper than half of Sarah's groceries)

O = Y + 2.10 (your other roommate's groceries were $2.10 more than your groceries)

We can use the second equation to substitute Y in the third equation:

O = Y + 2.10

O = (S/2) - 0.05 + 2.10

O = (S/2) + 2.05

We can now substitute both equations into the first equation:

S + Y + O = 82

S + ((S/2) - 0.05) + ((S/2) + 2.05) = 82

2S + 4 = 164

2S = 160

S = 80

Now that we know S, we can substitute it into the other equations to find Y and O:

Y = (S/2) - 0.05 = (80/2) - 0.05 = 39.95

O = Y + 2.10 = 39.95 + 2.10 = 42.05

So your share of the groceries was $39.95, your other roommate's share was $42.05, and Sarah's share was $80 - ($39.95 + $42.05) = $82 - $82 = $0.

The improper fraction for given mixed fraction 4 1/2 will be 9/2.

What exactly are fractions?

In mathematics, a fraction is used to represent a piece or part of a whole. A fraction is made up of two parts: the numerator and the denominator. The top number is known as the numerator, while the bottom number is known as the denominator. The denominator describes the total number of equal parts in a whole, whereas the numerator defines the number of equal parts taken.

Fractions are classified into four categories. They are as follows:

A unit fraction is the numerator of a fraction that begins with 1. 1/2 and 1/4 are two examples.

Proper Fraction - A proper fraction is one in which the numerator value is smaller than the denominator value. 7/9, 8/10, etc.

Improper Fraction - An improper fraction is one in which the numerator value is larger than the denominator value. 6/5, 11/10, etc.

Mixed Fraction - A mixed fraction is one that combines a whole number and a proper fraction. Example: 5 3/4, 10 1/2

now,

Given that

Mixed fraction is 4 1/2

to change this into improper fraction multiply 4*2 and add 1 to it

and divide it by 2 i.e. 8+1//2=9/2

hence,

         The improper fraction will be 9/2.

Answer:

x = - 2

Step-by-step explanation:

to find the x- intercept let h(x) = 0 and solve for x , that is

8\(\sqrt[3]{x-6}\) + 16 = 0 ( subtract 16 from both sides )

8\(\sqrt[3]{x-6}\) = - 16 ( divide both sides by 8 )

\(\sqrt[3]{x-6}\) = - 2 ( cube both sides to clear the radical )

( \(\sqrt[3]{x-6}\) )³ = (- 2)³

x - 6 = - 8 ( add 6 to both sides )

x = - 2

the x- intercept is - 2

2. \(\text{log a}+\text{log b}=\text{log}(a{\cdot} b)\)

3. \(\text{log}a^n=n\ \text{log} a\)

Now coming to question,

(a) \(\text{log 5}-\text{log 8}=\text{log} \dfrac{\text{5}}{\text{8}}\) (using property 1)

(b) \(\text{log 1}+\text{log 3}=\text{log}(1{\cdot} 3)=\text{log} 3\) (using property 2)

(c) \(\text{log} 4=\text{log} 2^2=2\ \text{log} 2\) (using property 3)

Answer:

\(25\text{ feet}\)

Step-by-step explanation:

The ladder, ground, and building form a right triangle where the vertical distance between the top of the ladder and the bottom of the ground is one leg, the horizontal distance between the bottom of the ladder and the building is another leg, and the length of the ladder is the hypotenuse.

For any right triangle, the Pythagorean Theorem states that the sum of the squares of both legs is equal to the hypotenuse squared (\(a^2+b^2=c^2\)), where \(c\) is the hypotenuse.

Let the length of the ladder be \(\ell\) (hypotenuse of right triangle). The distance between the top of the ladder and the ground (vertical distance) can be represented as \(\ell -1\).

From the Pythagorean Theorem, we then have:

\(7^2+(\ell-1)^2=\ell^2\)

Expand using \((a-b)^2=a^2-2ab+b^2\):

\(49+\ell^2-2\ell+1=\ell^2\)

Subtract \(\ell\) from both sides and add \(2\ell\) to both sides:

\(49+1=2\ell\)

Combine like terms:

\(50=2\ell, \\2\ell =50\)

Divide both sides by 2:

\(\ell=\frac{50}{2}=\boxed{25\text{ feet}}\)

Therefore, the length of the ladder is 25 feet.

commutative property of multiplication

Step-by-step explanation:

The equation of the parabola is: A. y = -2(x - 2)² + 18

In Mathematics, the vertex form of a quadratic function is represented by the following mathematical equation:

f(x) = a(x - h)² + k

Where:

Based on the information provided about the vertex (2, 18) and the x-intercept (5, 0), we can determine the value of "a" as follows:

y = a(x - h)² + k

0 = a(5 - 2)² + 18

-18 = 9a

a = -2

Therefore, the required quadratic function is given by:

y = a(x - h)² + k

y = -2(x - 2)² + 18

Step-by-step explanation:

To differentiate the function f(x) = 1/x^3, we can use the power rule of differentiation. Here's the step-by-step process:

Write the function: f(x) = 1/x^3.

Apply the power rule: For a function of the form f(x) = x^n, the derivative is given by f'(x) = nx^(n-1).

Differentiate the function: In our case, n = -3, so the derivative is:

f'(x) = -3 * x^(-3-1) = -3 * x^(-4) = -3/x^4.

Therefore, the derivative of the function f(x) = 1/x^3 is f'(x) = -3/x^4.

Answer: where is the answer choices

Step-by-step explanation:

Answer:

Explanation

There are some activities in Courseware content that report scores and some that just report mastery and/or completion status.

Resolution

Dynamic vs. Non-dynamic mastery tests

Mastery tests give mastery status if the score is 80% or higher, but not all tests report a score. There are two types of mastery tests in Courseware content:

Non-dynamic tests: Those that do report a score, such as those in the Writing Process and Practice titles, in the Grammar and Mechanics modules, give the same number of questions each time; these are non-dynamic tests. For example, Splitting Fused Run-ons: Mastery Test presents ten questions. Even if the Learner answers the first three questions incorrectly and is, at that point, no longer able to answer eight correctly to achieve mastery, the remaining seven questions are presented.

Dynamic tests: Mastery tests from some content titles, such as Essential Reading Skills, however, are dynamic, which means they adapt to the Learner's responses. These tests do not always give the maximum number of questions; instead, they will end sooner if 80% is either achieved or no longer achievable. These tests show mastery if 80% or better was achieved, but do not show a score. For example, in Essential Reading Skills, Pronouns: Mastery Test, the maximum number of questions presented is five; mastery requires four questions are answered correctly. The test will end early if the student answers the first four correctly or two incorrectly out of the first four. Mastery is still based on achieving 80% or better, but the score is not fully determined, so no score is reported, by design.
