The algebraic expression for the payment of the plan with y dollar surge is A = x/2 + y.
What are algebraic expressions?The concept of algebraic expressions is the use of letters or alphabets to represent numerical values without stating their exact meanings. The fundamentals of algebra taught us how to express an unknown value using letters like x, y, and z. Here, we refer to these letters as variables. Variables and constants can both be used in an algebraic expression. A coefficient is any value that is added before a variable and then multiplied by it.
Given that the annual premium plan is x dollars.
The payment is made semi-annually this is represented as follows:
x/2
There is a surplus charge of y, this is written as:
A = x/2 + y
Hence, the algebraic expression for the payment is A = x/2 + y.

What is the maximum number of comparisons in a bubble sort if there are 5 elements in the array?
The maximum number of comparisons in a bubble sort if there are 5 elements in the array = 10
Bubble Sort is the simplest sorting algorithm that works by repeatedly swapping the adjacent elements if they are in the wrong order. This algorithm is not suitable for large data sets as its average and worst-case time complexity is quite high.
Due to its simplicity, bubble sort is often used to introduce the concept of a sorting algorithm.
In computer graphics, it is popular for its capability to detect a tiny error (like a swap of just two elements) in almost-sorted arrays and fix it with just linear
complexity (2n).
Example: It is used in a polygon filling algorithm, where bounding lines are sorted by their x coordinate at a specific scan line (a line parallel to the x-axis), and with incrementing y their order changes (two elements are swapped) only at intersections of two lines
Calculating total number of comparison required to sort the array
= (n-1) + (n-2) + (n-3) + . . . 2 + 1
= (n-1)*(n-1+1)/2 { by using sum of N natural Number formula }
= n (n-1)/2
= 5(4)/2
=20/2
=10

A card is selected from a standard deck of cards, noted, and then without replacing the first card a second card is selected from the deck. What is the probability that both cards will be red cards
The probability that both cards will be red cards is P(A⋅B) = 25/102
What is probability?The possibility of the result of any random event is known as probability. This phrase refers to determining the likelihood that any given occurrence will occur.
The first event, random drawing of a red card (event A), has a sample space of an entire deck with 52 different elementary events occurring with equal probabilities of 1/52. Out of them only 26 events are "good" (that is, the card we randomly pick is red). Therefore, the probability of picking a red card equals to
P(A) = 26/52
P(A) = 1/2.
The second event, random drawing of a red card from a deck of only 51 remaining cards (event B), is dependent on the results of the first event. If the first event (event A) occurs (red card is drawn), the deck for the second drawing contains 25 red and 26 black cards and the conditional probability of picking red card is
P(B/A) = 25/51.
Now we can use the concept of conditional probability and a formula that describes the probability of a combined event through the probability of one and conditional probability of another:
P(A⋅B) = P(A) * P(B/A)
In our case P(A) = 1/2 and P(B/A) = 25/51
Therefore,
P(A⋅B) = (1/2) * (25/51)
P(A⋅B) =25/102

Therefore , the value of the given problem of linear equation comes out to be x = -250.
Define a linear equation.In algebra, a mathematical model is just one that of the form y=mx+b. The slope is B, and the y-intercept is m. Since x and y are variables, the previous sentence is frequently referred to as a "mathematical expression with 2 variables." Bivariate linear equations are linear equations with two variables. Linear equations can be found in many different situations. Once an issue has the formula y=mx+b, where m denotes the slope and b the y-intercept, it is said to be linear.
Here,
Given : 70.50 - 45.50 + 0.15x - 0.09x =0
To find the value of x,
Thus,
We do : 70.50 - 45.50 + 0.15x - 0.09x =0
=> 15 + 0.06x =0
=> 6/100 *x = -15
=> 6x = -1500
=> x = -1500/6
=> x = -250
Therefore , the value of the given problem of linear equation comes out to be x = -250.

Which statement defines the horizontal asymptote?
m < n, so y = 0 is the horizontal asymptote.
m = n, so y = am / bn is the horizontal asymptote.
m = n, so y = 0 is the horizontal asymptote.
m > n, so there is no horizontal asymptote.
The horizontal asymptote is y = 0 because m = n. A function's graph has a line known as a horizontal asymptote.
A horizontal asymptote is a line that the graph of a function approaches as x tends to either positive or negative infinity. If the degree of the numerator is equal to the degree of the denominator, then the horizontal asymptote of the function is the line y = a/b, whereThe leading coefficients in the denominator and numerator, respectively, are a and b. Therefore, if m = n, then the horizontal asymptote is y = a/b, which reduces to y = 0.
The statement that defines the horizontal asymptote is that if m = n, then the horizontal asymptote is y = 0.

The length, width, and height of the box is 23 inches, 24 inches, and 25 inches.
The desired length of the diagonal of the box d ≥ 41.5 inches
The length of the box = l
The width of the box = w
The height of the box = h
The formula for the diagonal of the box, obtained using the Pythagorean Theorem is:
d = [tex]\sqrt[]{l^{2}+w^{2}+h^{2} }[/tex]
So, the square of the diagonal of the box, d² ≥ 41.5² = 1722.25
[tex]d^{2} = l^{2} + w^{2} + h^{2}[/tex]
l² + w² + h² ≥ 1722.25

What is the exact value of tan (startfraction 5 pi over 8 endfraction)?
After solving, the exact value of tan5π/8 = -2.425
In the given question we have to find the exact value of tan5π/8.
The angles and sides of a right-angle triangle are measured using these trigonometric values. Cotangent, secant, and cosecant are the other three significant values in addition to sine, cosine, and tangent.
To find the value of tan5π/8 we simplify the values.
Rephrase 5π/8 as the angle divided by two where the values of the six trigonometric functions are known.
tan5π/8 = tan[(5π/4)/2]
Now applying the tangent half-angle identity.
tan5π/8 = ±√[{1-cos(5π/4)}/{1+cos(5π/4)}]
The tangent is negative in the second quadrant, so change the ± to -.
tan5π/8 = -√[{1-cos(5π/4)}/{1+cos(5π/4)}]
We know the value of cos(5π/4) = -1/√2
Now putting the value
tan5π/8 = -√[{1-(-1/√2)}/{1+(-1/√2)}]
tan5π/8 = -√[{1+1/√2}/{1-1/√2}]
tan5π/8 = -√[{√2+1}/√2/{√2-1}/√2]
tan5π/8 = -√(√2+1)/(√2-1)
As we know that, √2 = 1.41. So
tan5π/8 = -√(1.41+1)/(1.41-1)
tan5π/8 = -√(2.41)/(0.41)
tan5π/8 = -√5.88
tan5π/8 = -2.425

The exact value of tan (5π/8) is 1.7320508076.
The exact value of tan (5π/8) can be calculated using the tangent of a sum formula. The formula states that tangent of (A+B) can be calculated by the formula:
tan(A+B) = (tan A + tan B) / (1 - tan A tan B).
Therefore, we can calculate the tan (5π/8) as follows:
tan (5π/8) = tan (3π/4 + π/8)
= (tan (3π/4) + tan (π/8)) / (1 - tan (3π/4) tan (π/8))
= (√2 + 0.3826834) / (1 - √2 * 0.3826834)
= 1.7320508076
Therefore, the exact value of tan (5π/8) is 1.7320508076.
