Step-by-step explanation:

The volume of a rectangular prism is given by the formula V = lwh, where l is the length, w is the width, and h is the height of the prism. In this case, the height of the prism is (1/2x-3), the length is (x+5), and the width is (x-4).

Substituting these values into the volume formula, we get:

V = (1/2x-3)(x+5)(x-4)

Expanding this expression using the distributive property, we get:

V = (1/2x^2 - 3x)(x+5)(x-4)

Using the distributive property again, we get:

V = (1/2x^2 - 3x)(x^2 + x - 20)

Using the distributive property once more, we get:

V = 1/2x^3 - 3x^2 - 4x + 20

This expression is equivalent to the expression in answer choice D. Therefore, the correct answer is D. (5/2x^3 -3/2x^2 +13x+ 20)

Answer: x=1+√47 or x=1−√47 (Assuming that the "2x2" is 2x^2)

Step-by-step explanation:

Step 1: Subtract x^2+5x+39 from both sides.

2x2+3x−7−(x2+5x+39)=x2+5x+39−(x2+5x+39)

x2−2x−46=0

For this equation: a=1, b=-2, c=-46

1x2+−2x+−46=0

Step 2: Use quadratic formula with a=1, b=-2, c=-46.

x=1+√47 or x=1−√47

The statement is asserting that the universal class (V) is defined as the collection of all sets, where every set is included. It signifies that V encompasses all possible sets within the given set theory framework.

The statement "The universal class set, or universe, is the class of all sets: V = {x: x = x}" is referring to the concept of the universal class or the universe in set theory.

In set theory, the universal class set, denoted as V, represents the collection or class that contains all sets. It includes every possible set that can be defined or exists within the context of the set theory being considered.

The notation "{x: x = x}" is used to define the elements of the universal class. Here, "x = x" represents a condition that is always true for any object or element, regardless of its nature. In other words, this condition holds for everything in the universe, as anything is equal to itself.

Given that 16 families went on a trip and the cost of the trip was Rs. 2,16,352.The amount paid by each family is to be determined by unitary method Hence each family paid Rs.13522

Now, let's solve this by using the method of unitary method. To find the cost of 1 family trip, we will divide the total cost of the trip by the number of families.2,16,352 / 16 = 13,522 So, the cost of the trip per family is Rs. 13,522.Hence, each family paid Rs. 13,522 for the trip.

https://brainly.com/question/28276953

Answer:

Step-by-step explanation

1. The total cost of the trip for all 16 families is Rs 2,16,352.
2. To find out how much each family paid, we need to divide the total cost by the number of families: Rs 2,16,352 ÷ 16.
3. When we do the division, we get the result: Rs 13,522.

Now let's check if this result is correct:

1. If each family paid Rs 13,522 for the trip, then the total cost for all 16 families would be: 16 × Rs 13,522 = Rs 2,16,352.
2. This is exactly the same as the total cost given in the problem statement.

So we have shown that each family paid **Rs 13,522** for the trip

Answer:

To find the formula for (g∘f)(x), we need to first evaluate g(f(x)):

g(f(x)) = g(x+3) = (3(x+3)+5)/3 = (3x+14)/3

So, (g∘f)(x) = (3x+14)/3

To find the domain for (g∘f)(x), we need to consider any restrictions on x that would make the function undefined. The only possible restriction is if the denominator of (3x+14)/3 is zero, which occurs when 3x+14=0. Solving for x, we get x=-14/3. Therefore, the domain of (g∘f)(x) is all real numbers except -14/3, or (-∞, -14/3) U (-14/3, ∞).

Step-by-step explanation:

The equation is 8x - 71 = 5x + 4. Then the value of the variable 'x' will be 25.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.

Vertically opposite angle - When two lines intersect, then their opposite angles are equal.

The angles are (5x + 4)° and (8x - 71)°. And the angels are vertically opposite angles. Then the equation is given as,

8x - 71 = 5x + 4

Simplify the equation, then we have

8x - 71 = 5x + 4

8x - 5x = 71 + 4

3x = 75

x = 75 / 3

x = 25

The condition is 8x - 71 = 5x + 4. Then the worth of the variable 'x' will be 25.

The solution set includes all real numbers less than -5, and all real numbers greater than 1, but does not include -5 or 1 themselves.

Option D is the correct answer.

We have,

We need to isolate the absolute value |x + 2| on one side of the inequality.

We subtract 7 from both sides.

|x + 2| > 3

Next, we can split this inequality into two separate inequalities, one for when the expression inside the absolute value is positive, and one for when it is negative:

x + 2 > 3

or

- (x + 2) > 3

Solving for x in the first inequality.

x > 1

Solving for x in the second inequality.

-x - 2 > 3

Adding 2 to both sides and multiplying by -1.

x < -5

So the solution set for the inequality |x + 2| + 7 > 10 is the set of all x-values that satisfy either x > 1 or x < -5.

Using interval notation.

(-∞, -5) U (1, ∞)

Thus,

The solution set includes all real numbers less than -5, and all real numbers greater than 1, but does not include -5 or 1 themselves.

Hence, 2 3/8 is the answer.

The measure of <MNL is (71 - 3x²)/2.

Far Arc = 59 - 2x²

Near Arc = 12 - x²

Angle = 180- 2x²

Using the Formula

Angle= Average of vertical chords

180 - 2x² = (59 - 2x² + 12 - x²)/2

Answer:

\(\frac{10x^2+3}{y^2+4}\)

Step-by-step explanation:

When adding rational numbers, if the denominator is the same you simply keep the denominator (bottom of fraction) as it is and apply the operation given to the numerator ( top of fraction )

So we have \(\frac{6x^2+5}{y^2+4} +\frac{4x^2-2}{y^2+4} =\frac{(6x^2+5)+(4x^2-2)}{y^2+4}\)

==> remove parenthesis and apply signs

\(\frac{x^2+5+4x^2-2}{y^2+4}\)

==> simplify numerator by combining like terms

\(\frac{10x^2+3}{y^2+4}\)

and we are done!

Note:

like terms are terms with the same variable and exponent

An example of like terms are 6x^7 and 3x^7 as they have x as a variable and a power of 7

The like terms being combined here were (6x² and 4x²) and (5 and -2)

Answer:

\(\frac{10x^{2} +3}{y^{2}+4 }\)

make the common denominator

\(\frac{6x^{2} +5+4x-2}{y^{2}+4 }\)

combone the like terms

\(\frac{10x^{2} +5-2}{y^{2}+4 }\)

subtract numbers

\(\frac{10x^{2} +3}{y^{2}+4 }\)

The result when 4x³ + 15x² + 17x + 6 is divide by 4x + 3 using long dividion method will be x² + 3x + 2.

This is somewhat hard to explain for me. I attached a picture/diagram to help.

They are congruent angles.

Angle N, inside the MNP triangle is 34. Which means the adjacent angle is 56.

The interior angles of a triangle add up to 180.

So to find angle M in triangle LNM, we can do 180 - 90 - 56.

Step-by-step explanation:

(1). (f(0) = 2) > (g(0) = - 4) (True)

(2). f( - 4) = 4( - 4 ) + 2 = - 14

g( - 4) = (5/2)(- 4) - 4 = = - 14

f( - 4) = g( - 4) (True)

(3). f(6) = 4(6) + 2 = 26

g(12) = (5/2)(12) - 4 = 26

f(6) = g(12) (True)

(4). g(2) = (5/2)(2) - 4 = 1

f(2) = 4(2) + 2 = 10

g(2) > f(2) (False)

The probability that a person will wait for between 10 and 12 minutes is  0.069.

z-score is defined as the number of standard deviations by which the value of a raw score is above or below the mean value of what is being measured or observed. It tells where the score lies on a normal distribution curve. It is a numerical measurement  that describes a values relationship to the mean of a group of values.

z = (raw score - mean) / standard deviation

Given,

The mean waiting time is 6 minutes and variance waiting time is 9 minutes.

Standard deviation = √variance = √9 = 3minutes

For between 10 and 12 minutes, the probability is

z = (10- 6)/3 = 1.333 and z=(12-6)/3=2

p(z≤1.3333)=0.982

p(z≤2)=0.9772

Probability that a person will wait for between 10 and 12 minutes is,
