Which line is perpendicular to 3 x+2 y=6 ?
(A) 4x - 6y = 3
(B) y = -(3/2)x + 4
(C) 2x + 3y = 12
(D) y = (3/2)x+1
Answers
The equation of the line 3x + 2y = 6 is perpendicular with the equation of the line (A) 4x - 6y = 3.
Two lines are perpendicular with each other if they form right angle at the point of their intersection. The slopes of perpendicular lines are negative reciprocal of one another.
The slope, m, determines the steepness of a line. It can be measured by the vertical distance from one point to another divided by the horizontal distance of the same points.
In an equation in standard form, ax + by = c, the slope, m, of the line is equal to a/b. On the other hand, in an equation in slope-intercept form, y = mx + b, m is the slope.
Determine the slope of the given line and each given choices:
3x + 2y = 6
m = a/b = 3/2
(A) 4x - 6y = 3
m = a/b = 4/-6 = -2/3
(B) y = -(3/2)x + 4
m = -3/2
(C) 2x + 3y = 12
m = a/b = 2/3
(D) y = (3/2)x + 1
m = 3/2
Since the slope of the given line is 3/2, taking its negative reciprocal, the slope of the perpendicular line should be -2/3. The line with the slope of -2/3 is (A) 4x - 6y = 3.
Hence, (A) 4x - 6y = 3 is perpendicular with 3x + 2y = 6.

The probability that a point is chosen at random will lie in the shaded area will be 0.32.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
Here favorable outcomes will be the shaded portion and the total outcome will be the total circular portion.
Favorable Outcome = Area of shaded portion = 1/2 x 18 x 18/2

Total Outcome = Total area = 81 π inch sq.
Probability, P(E) = 81/ 81 π = 1/32
Hence, the probability that a point chosen at random will lie in the shaded area is 0.32.

What is the sequence of AP arithmetic progression?In Arithmetic Progression, the difference between the two mathematical orders is a constant value (AP). Arithmetic Sequence is another name for it.
We'd come across a few important words in AP that were denoted as:
The first term (a)Common difference (d)Term nth (an)The total of first n terms (Sn)As shown below, the AP also can be described in aspects of common differences.
The following is the formula for evaluating an AP's n-th term: an = a + (n − 1) × dThe arithmetic progression sum is as follows: Sn = n/2[2a + (n − 1) × d].Common difference 'd' of an AP: d = a2 - a1 = a3 - a2 = a4 - a3 = ...... = an - an-1.Now, the given sequence is; 15,23,31, ...........
Consider the first term is'a₁' = 15
Consider 'a₂' = 23 is the second term.
Consider the third term is 'a₃' = 31
Calculate the common difference;
d = a₂ - a₁
Put the values in the above obtained equation;
d = 23 - 15 = 8
Now, to estimate the value of the 10th term using the formula of nth term.
an = a + (n − 1) × d , n = total number of terms = 10.
Put all the values;
a₁₀ = 15 + (10 - 1) × 8
a₁₀ = 15 + 9 × 8
a₁₀ = 15 + 72
a₁₀ = 87
Therefore, the value of the 10th term is calculated as a₁₀ = 87.

The solution of the given equation √(4x-23) - 3 = 2 is (x = 14.25).
What is meant by square numbers?A 'Square Number' is the result of multiplying a number or integer (not really a fraction) by itself.
For instance, 3 multiplied by 3 equals 3 squared, or 3 x 3 = 32. So, in essence, a square number is really the exponential form of multiplying a number or integer by itself. Also, if we multiply the number on its own again, we get the integer's cube, a x a x a = a³.Now, as per the given equation;
√(4x-23) - 3 = 2
This could also be written as;
√(4x-23) = 2 + 3
√(4x-23) = 5
Now, squaring on the both side;
(4x-23) = 25
Open the brackets;
4x - 32 = 25
4x = 25 + 32
4x = 57
x = 14.25

Which equation does NOT represent a direct variation?

c. 2 x-y=0
d. 2 x-5 y=0
Answers
The graph of 2x - y = 5 does not represent a direct variation.
Direct variation is variation in which the quotient of the two variables is constant. A constant ratio of two quantities means that one quantity varies directly with the other or that the two quantities vary directly. In symbols, the direct variation formula is y=k*x or k=y/x.
k is known as the constant of variation or the constant of proportionality.
This means that as x increases, y increases, and as x decreases, y decreases, and their ratio is always the same.
The graph of the direct variation equation is a straight line through the origin.
The graph of 2x-y =5 does not pass through the origin, so it does not represent a direct variation. (consult the images attached below).

By comparing the intercepts of the linear equation with the ones in the graph, we conclude that the given graph corresponds with the linear equation.
How to know if the graph represents the given equation?
Here we have the linear equation:
1.5*s + 3.5*c = 21
And we have a graph, which we want to see if it is the graph of the linear equation.
To check this, we just need to look at the intercepts, the variable "c" is on the vertical axis and the variable "s" is on the horizontal axis.
The "s" intercept is what we get when we take c = 0, replacing that we will get:
1.5*s + 3.5*0 = 21
1.5*s = 21
s = 21/1.5 = 14
This means that the line should pass through the point (14, 0), and we can see that this happens.
The other intercept is what we get when we take s = 0.
1.5*0 + 3.5*c = 21
c = 21/3.5 = 6
The other intercept is at (0, 6), which we also can see on the graph.
With that is enough to conclude that the given graph represents the given linear equation.
