Answer:
x = -1/2 x = -1/2 x = -14/5 x = 3Step-by-step explanation:
1) 3(2x + 9) = 24, find x?
→ 3(2x + 9) = 24
→ 6x + 27 = 24
→ 6x = 24 - 27
→ x = -3/6
→ [ x = -1/2 ]
Hence, value of x is -1/2.
2) 4x - 2 = 10x + 1, find x?
→ 4x - 2 = 10x + 1
→ 4x - 10x = 1 + 2
→ -6x = 3
→ x = -3/6
→ [ x = -1/2 ]
Hence, value of x is -1/2.
3) 3x - 4(2x + 1) = 10, find x?
→ 3x - 4(2x + 1) = 10
→ 3x - 8x - 4 = 10
→ -5x = 10 + 4
→ [ x = -14/5 ]
Hence, value of x is -14/5.
4) 3x + 10 = 19, find x?
→ 3x + 10 = 19
→ 3x = 19 - 10
→ x = 9/3
→ [ x = 3 ]
Hence, value of x is 3.

In a triangle PQR, right-angled at Q, PR = 37 inches and angle R =
30°. Find: sin R
The required value of PQ is 18.5 inches in the given triangle PQR.
What is right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
As per the given question, let's call the length of side PR (the hypotenuse). Since we know that PR = 37 inches and angle R = 30°, we can use the sine rule to write the following equation:
sin R = perpendicular/hypotenuse
sin R = PQ/PR
sin 30° = PQ/37
1/2 = PQ/37
PQ = 37/2
Apply the division operation, and we get
PQ = 18.5
Therefore, the required value of PQ is 18.5 inches.

Athematic is a type of language that does not use inflectional morphology. This means that words do not change their form to indicate different aspects of meaning, such as tense, person, number, gender, case, and mood. Instead, the meaning of a sentence is conveyed through the use of different words and word order. Many languages, such as English, Chinese, and Japanese, are athematic. Additionally, some languages, such as Russian, have both athematic and inflectional forms.

What is multicollinearity ?
Correlations between two or more independent variables in a multiple regression model can be referred to as multicollinearity. When a researcher or analyst tries to figure out how well each independent variable can be utilized to predict or comprehend the dependent variable in a statistical model, multicollinearity can result in skewed or misleading conclusions.
When two or more explanatory variables in a multiple regression model have strong linear relationships with one another but not with the dependent variable, this is referred to as multicollinearity.

A force does work on a 50 g particle as the particle moves along the following straight paths in the xy-plane: 25 j from (0 m, 0 m) to (5 m, 0 m); 35 j from (0 m, 0 m) to (0 m, 5 m); -5 j from (5 m, 0 m) to (5 m, 5 m); -15 j from (0 m, 5 m) to (5 m, 5 m); and 20 j from (0 m, 0 m) to (5 m, 5 m).
1) It is a conservative force, yes.
2) At (5m, 5m), the potential energy is 20 J.
1) If the work that a force performs when moving an item depends only on the object's initial and final positions and not on the path travelled, the force is said to be conservative.
Let's verify if this condition is met for the force in this problem:
- For moving from (0 m, 0 m) to (5 m, 5 m), the work done is 20 J (A)
Then we can go from (0 m, 0 m) to (5 m, 5 m) through a different path:
- from (0 m, 0 m) to (5 m, 0 m) (work done: 25 J)
- from (5 m, 0 m) to (5 m, 5 m) (work done: -5 J)
Total work done in the second path: 25 J + (-5 J) = 20 J --> same as (A)
We can also go from (0 m, 0 m) to (5 m, 5 m) through a different path:
- from (0 m, 0 m) to (0 m, 5 m) (work done: 35 J)
- from (0 m, 5 m) to (5 m, 5 m) (work done: -15 J)
Total work done in the third path: 35 J + (-15 J) = 20 J --> same as (A)
So, the force is conservative, since the work done does not depend on the path taken.
2) For a conservative force, the change in potential energy of the object moved by the force is equal to the work done by the force in moving the object from A to B.
Here have:
Point A: (0m, 0m)
Point B: (5m, 5m)
In this problem, the potential energy at the origin (point A) is zero, so,
[tex]W = U_{b} - U_{a}[/tex]
Also we know that the work done is W = 20 J
So, we find
[tex]U_{b} = W + U_{a}\\=20 + 0\\= 20J[/tex]

Given:
a tree contains some number of leaves (degree 1 vertices) and four non-leaf vertices.
the degrees of the non-leaf vertices are 10, 7, 4, and 4.
how many leaves does the tree have = ?
The degree of the non leaf vertices are 10, 7, 4, 4
let the number of leaves be = k
So the tree has 4+k vertices.
and hence (4+k)-1 edge ⇒ 3+k
so ∑ deg(v) = 10+7+4+4+1k
= 25+k
and 2[E(T)] = ∑ deg(v)
2(3+k) = 25+k
6 + 2k = 25+k
2k-k = 25-6

Veronica is choosing between two health clubs. After how many months will the total cost for each health club be the same?
In 4 months, the total cost of Yoga Studio A would equal that of Yoga Studio B
What is total ?
Total refers to an entire or complete amount, and the verb "to total" means to combine two numbers or to destroy anything. In mathematics, you add integers to get the total; the outcome is the total. The result of adding 8 and 8 is 16.
The cost of Yoga Studio A at any given month can be represented as:
= Membership fee + (Monthly fee x Number of months)
Assuming number of months is x, the formula would be:
= 24 + (21.50 × x)
= 24 + 21.50x
Yoga Studio B would be:
= 41 + (17.25 × x)
= 41 + 17.25x
In order to find the month that these costs would be equal, equate both formulas:
24 + 21.50x = 41 + 17.25x
21.50x - 17.25x = 41 - 24
4.25x = 17
x = 17 / 4.25
x = 4 months
In conclusion, their costs would be the same in the 4th month.
