What is the value of b in the equation below?

Answer:

serious??? D-180

Step-by-step explanation:

Answer:

21

Step-by-step explanation:

Note that n! = n(n - 1)(n - 2) ..... × 3 × 2 × 1, thus

7! = 7 × 6 × 5 × 4 × 3 × 2 × 1

5! = 5 × 4 × 3 × 2 × 1

2! = 2 × 1

Hence

cancel 5 × 4 × 3 × 2 × 1 on numerator/ denominator, leaving

[tex]\frac{7(6)}{2(1)}[/tex] = [tex]\frac{42}{2}[/tex] = 21

After evaluating the given information about the algebraic and graphed functions, we can conclude that the algebraic function f(x) = -5x^2 - 8x, which is a downward-opening parabola, has a greater maximum value than the graphed function in question. Therefore, the correct answer is option A.

To compare the algebraically expressed function f(x) = -5x^2 - 8x with a given graphed function, we need to look at their respective shapes and key features. Since f(x) is a quadratic function with a negative coefficient for the x^2 term, it is a downward-opening parabola that will have a maximum value. Without more information about the graphed function, we can still analyze the given description to ascertain its nature.

Based on the given statements, let's identify which function has a greater maximum or a lower minimum value:

In conclusion, given that f(x) = -5x^2 - 8x is a downward-opening parabola with a definite maximum value, and none of the provided statements about the graphed function suggest it has a maximum value higher than a constant value or a parabola, we can conclude that:

The algebraic function has a greater maximum value, so the correct answer would be option A.

The graphed function has a greater maximum value. The algebraic function's downward-opening parabola indicates a maximum value, and the graphed function's characteristics suggest it may have a higher maximum (option c).

To determine the maximum values of the algebraic function [tex]\(f(x) = -\frac{5}{2}x^2 - 8x\)[/tex] and the graphed function, we need to analyze the coefficient of the quadratic term in the algebraic expression. The quadratic term is [tex]\(-\frac{5}{2}x^2\)[/tex], and since the leading coefficient is negative, the parabola opens downwards. This means that the algebraic function has a maximum value, and the coefficient [tex]\(-\frac{5}{2}\)[/tex] determines the concavity.

Comparatively, the graphed function on the graph may have a different leading coefficient, affecting the concavity. If the graphed function has a positive leading coefficient, it opens upwards, suggesting a minimum value. Conversely, if it has a negative leading coefficient, it opens downwards, indicating a maximum value (option c).

In the case of the given options, statement C is correct. The graphed function has a greater maximum value because the leading coefficient of the quadratic term in the algebraic function is negative, resulting in a downward-opening parabola with a maximum point. Therefore, the graphed function, depending on its characteristics, may exhibit a greater maximum value.

The complete question of the given answer is:

Compare the algebraically expressed function [tex]\(f(x) = -\frac{5}{2}x^2 - 8x\)[/tex] to the function shown in the graph to determine which statement is true.

A) The algebraic function has a greater maximum value.

B) The algebraic function has a lower minimum value.

C) The graphed function has a greater maximum value.

D) The graphed function has a lower minimum value."

5. 16, 32, 48, 64, 80

EXPLANATION

An arithmetic sequence has a constant difference.

1. –5, 5, –5, 5, –5, … is not an arithmetic sequence because 5--5≠ -5-5

2. 96, 48, 24, 12, 6 is not an arithmetic sequence because 48-96≠ 24-48

3. 18, 5.5, –7, –19.5, –32, … is an arithmetic sequence because there is a constant difference of

[tex]5.5 - 18 = - 12.5[/tex]

4. –1, –3, –9, –27, –81, … is not an arithmetic sequence because

[tex] - 3 - - 1 = - 9 - - 3[/tex]

the perimeter of the triangle shown on the coordinate plane to the nearest tenth of a unit is 21 units. Therefore, option c is the correct answer.

To find the perimeter of the triangle shown on the coordinate plane, we need to calculate the lengths of each side and then add them together.

Step 1: Calculate the length of the first side.

Using the distance formula, the length of the side connecting (-3, 3) and (3, -3) is:

√[(3 - (-3))^2 + (-3 - 3)^2] = √[6^2 + (-6)^2] = √[36 + 36] = √72.

Step 2: Calculate the length of the second side.

Using the distance formula, the length of the side connecting (3, -3) and (3, 3.5) is:

√[(3 - 3)^2 + (3.5 - (-3))^2] = √[0^2 + 6.5^2] = √[0 + 42.25] = √42.25.

Step 3: Calculate the length of the third side.

Using the distance formula, the length of the side connecting (3, 3.5) and (-3, 3) is:

√[(-3 - 3)^2 + (3 - 3.5)^2] = √[-6^2 + (-0.5)^2] = √[36 + 0.25] = √36.25.

Step 4: Calculate the perimeter by adding the lengths of the sides.

Perimeter = √72 + √42.25 + √36.25.

Now we can simplify the answer to the nearest tenth:

Perimeter ≈ 8.5 + 6.5 + 6 = 21.

Therefore, the perimeter of the triangle shown on the coordinate plane to the nearest tenth of a unit is 21 units.

Therefore, option c is the correct answer.

Answer:  option C

[tex]x=-10\\y=11[/tex]

Step-by-step explanation:

You can apply the elimination method:

- Multiply the second equation by 3.

- Add both equations to cancel out the variable x.

- Solve for y:

[tex]\left \{ {{-3x+5y=85} \atop {(3)(x+4y)=34(3)}} \right.\\\\\left \{ {{-3x+5y=85} \atop {3x+12y=102}} \right.\\-------\\17y=187\\y=11[/tex]

- Substitute y=11 into any of the original equations ans solve for x. Then:

[tex]x+4(11)=34\\x=34-44\\x=-10[/tex]

The answers are:

[tex]x=-10\\y=11[/tex]

We can solve system of equations using several methods, but the simplest way to solve it, is isolating variables in terms of another variables.

So, isolating "x" from the second equation we have:

[tex]x + 4y =34\\x=34-4y[/tex]

Then, substituting "x" into the first equation, we have:

[tex]-3(34-4y) +5y =85\\-102+12y+5y=85\\17y=85+102\\17y=187\\y=\frac{187}{17}=11\\[/tex]

Now, substituting "y" into the second equation to calculate "x", we have:

[tex]x + 4(11) =34\\x=34-44\\x=-10[/tex]

So, the solutions for the system of equations are:

[tex]x=-10\\y=11[/tex]

Julie can type 3 pages in x minutes; to find the time to type 11 pages, set up a proportion and solve, resulting in 11x/3 minutes.

Since Julie can type 3 pages in x minutes, the rate at which Julie types is 3 pages per x minutes. If we want to find out how many minutes it will take her to type 11 pages, we simply set up a proportion based on her typing rate:

3 pages / x minutes = 11 pages / y minutes

To solve for y, which is the time it will take to type 11 pages, we cross-multiply and get:

3y = 11x

Then, we divide both sides of the equation by 3, yielding:

y = 11x / 3

The answer is option (e): 11x / 3.

Answer: Third option.

Step-by-step explanation:

A ⊂ B this means that A is subset of B.

If A is subset of B (A ⊂ B), then all the elements of A belong to the subset B.

For example, the set of the Natural numbers is a subset of the Real Numbers.

Then, A ∩ B are all the elements that belong to AB at the same time.

A ∪ B are all the elements of A and all the elements of B.

But if we already said that A is inside of B, then:

 A ∩ B = A ≠ A ∪ B

A ∩ B = A ∪ B only happen when the set A=set B.

Therefore, the answer is: NEVER.

Answer:

Excluded values are 3 and -4

Step-by-step explanation:

To simplify the expression multiply to create a common denominator.

Multiply the first fraction by (x-3) and the second fraction by (x+4).

[tex]\frac{3}{x+4} + \frac{4}{x-3}\\\\\frac{3(x-3)}{(x+4)(x-3)} + \frac{4(x+4)}{(x-3)(x+4)}[/tex]

[tex]\frac{3(x-3)}{(x+4)(x-3)} + \frac{4(x+4)}{(x-3)(x+4)} \\\\\frac{3(x-3) + 4(x+4)}{(x-3)(x+4)}\\\\\frac{3x - 9 + 4x + 16}{(x-3)(x+4)}\\\\\frac{7x + 7}{(x-3)(x+4)}[/tex]

Excluded values are values which make the denominator 0. This means (x-3)(x+4) cannot be 0. This means x cannot be 3 or -4. These are excluded values.

Answer:

28.4

Step-by-step explanation:

Translate the statement into an equation, and then solve the equation.

Let x be the number we are looking for.

155% of what number is 44?

155% of x is 44

In math "of" usually means multiplication.

155% * x = 44

To change a percent to a decimal, divide by 100 which means move the decimal point 2 places left. 155% = 155/100 = 1.55

1.55x = 44

Divide both sides by 1.55 to solve for x.

1.55x/1.55 = 44/1.55

x = 28.4
