)
The determinant of the matrix is;
|A| = (a.d) - (b.c)
Therefore, to appear with numbers for a, b, c, and d, we must ensure; (a.d) - (b.cdeterminantse, if a = 3, d = 15, b = 2, and v = 1.
Ultimately, |A| = (3×5) - (2×1) = 13
Find the 32 nd term of each sequence. -9,-8.7,-8.4, ...........
The 32th term of the arithmetic sequence AP is estimated to be 0.3.
What is meant by arithmetic sequence AP?In math, an arithmetic progression (AP) is a list or sequence of numbers in which each term is obtained by adding a finite number to the term before it.
The fixed number is known as the arithmetic progression's common difference written by 'd'The common difference of AP is 'd': d = a2 - a1 = a3 - a2 = a4 - a3 =...... = a - an-1.nth term of an AP: an = a + (n - 1) dThe sum of n terms of an AP's is Sn = n/2(2a+(n-1)d) = n/2(a + l), where l is the final term of the AP.Now for the answer to the question;
The numbers in the given sequence are-
-9,-8.7,-8.4, ...........
There are 32 terms with in series for that we need to find the 32nd number.
Let's say the first term is 'a₁' = -9.
Let 'a₂' = -8.7 be the second term.
Let 'a₃' = -8.4 be the third term.
The common difference between two consecutive terms that are equal of an AP is 'd.'
d = a₂ - a₁
Substitute the values in the preceding equation; the 32nd term is
d = -8.7 - (-9)
d = -8.7 + 9
d = 0.3
Now calculated using the nth term formula.
nth term of an AP: an = a + (n - 1) dTotal number of terms is; n = 32First term is a = -9common difference d = 0.3Substitute all of the values in the formula now.
a₃₂ = a + (n - 1) d
a₃₂ = -9 + (32 - 1)(0.3)
a₃₂ = -9 + 9.6 - 0.3
a₃₂ = 0.3
As a result, the arithmetic sequence's 32nd term is estimated to be 0.3.

Prove: Δ M L O ≅ ΔM N O
It is proved that ΔLMN is an isosceles triangle.
What exactly do we mean by a triangle's congruency?Two triangles are said to be congruent if all three corresponding sides are equal and all three corresponding angles are equal in measure.These triangles can be moved, rotated, flipped, and turned to appear identical.If they are repositioned, they will coincide.If two triangles satisfy the five congruence conditions, they are congruent.They are side-side-side (SSS), side-angle-side (SAS), angle-side-angle (ASA), angle-angle-side (AAS), and right angle-hypotenuse-side (RHS).So,
Given:
LM ≅ NMMO bisects ∠L M NTo prove congruency:
MO = MO (Common line)LM = NM = Given∠LM0 = ∠NMO = equal angles (As MO bisects ∠LMN)Therefore, ΔM LO ≅ ΔMNO under SSA congruency.

Write the equation of each line in slope-intercept form and identify the slope.
4 x+6 y=12
The equation of the line 4x + 6y = 12 expressed in slope-intercept form is y = -2/3 x + 2 with a slope equal to -2/3.
The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.
The slope-intercept form of the equation of a line is given by the formula:
y = mx + b
where m is the slope of the line
b is the y- intercept
Given the equation of the line 4x + 6y = 12, which is in standard form, transform it into slope-intercept form by isolating the variable y in one side.
4x + 6y = 12
6y = -4x + 12
Dividing both sides by 6,
y = -4/6 x + 2
y = -2/3 x + 2
Hence, the equation of the line in slope-intercept form is y = -2/3 x + 2 where the slope, m, is equal to -2/3.

Urijah is starting a food cart business. The cost to start the business is $20,000 and the monthly costs are $8,000. He has been earning $8,800 every month in revenue. In how many months will Urijah's business break-even and earn a profit?
He will break even on the 25th month.
How to find the number of month his business will break even?The cost to start the business is $20,000 and the monthly costs are $8,000.
He has been earning $8,800 every month in revenue.
Profit = Selling Price - Cost Price
Therefore,
let
x = number of month
Hence,
selling price = 8800x
cost price = 20000 + 8000(x) = 20,000 + 8000x
Therefore,
profit = 8800x - (20,000 + 8000x)
profit = 8800x - 20000 - 8000x
profit = 8800x - 8000x - 20000
profit = 800x - 20000
Hence,
The month when they will break even is as follows:
8800x = 20,000 + 8000x
20000 = 8800x - 8000x
20000 = 800x
x = 20000 / 800

A major fishing company does its fishing in a local lake. The first year of the company's operations it managed to catch 175,000 fish. Due to population decreases, the number of fish the company was able to catch decreased by 8% each year. How many total fish did the company catch over the first 10 years, to the nearest whole number?
The company catches 1,237,275.5 fishes over 10 years.
Given that, a company catches 175000 fishes in a year, the population decreases, the number of fish the company was able to catch decreased by 8% each year.
So, the population in 10 year =
The second year = 175000 × 0.92 = 161000
The third year = 161000 × 0.92 = 148120
The fourth year = 148120 × 0.92 = 136,270.4
The fifth year = 136270.4 × 0.92 = 125368.8
The sixth year = 125268.8 × 0.92 = 115339.3
The seventh year = 115339.3 × 0.92 = 106112.2
The eighth year = 106112.2 × 0.92 = 97623.2
The ninth year = 97623.2 × 0.92 = 89813.3

Find the value of x if A C=4 x-3, D C=2 x+9, m∠ E C A=15 x+2, and EC is a median of ΔAED. Is EC also an altitude of Δ A E D ? Explain.
If AC = 4x - 3, DC = 2x + 9, m ∠ ECA = 15x + 2, and EC is a median of ΔAED then EC is not an altitude of ΔAED because of m ∠ ECA = 92.
What is meant by the altitude of a triangle?
In geometry, an altitude is a line that passes through two very specific points on a triangle: a triangle's vertex, or corner, and its opposite side at a right, or 90-degree, angle. The base is the opposite side. Triangles have three vertices and three opposite sides in common.
Given: AC = DC
4x - 3 = 2x + 9
4x - 2x - 3 = 2x - 2x + 9
simplifying the above equation, we get
2x - 3 = 9
2x - 3 + 3 = 9+3
2 x = 12
x = 6
Substitute the value of x in m ∠ ECA, then we get
m ∠ ECA = 15x + 2
= 15(6) + 2
m ∠ ECA = 92
EC is not an altitude of ΔAED because of m ∠ ECA = 92.
Therefore, EC is not an altitude of ΔAED.

What is the slope of a line perpendicular to the line whose equation is x+4y=16x+4y=16. Fully simplify your answer.
The slope of a line perpendicular to the line of x + 4y = 16 is 4.
What is the slope of a line perpendicular to the line of the given equation?Given the equation of line;
x + 4y = 16
First, rearrange in slope intercept form ( y = mx + b ) by solving for y
x + 4y = 16
Subtract x from both sides
x - x + 4y = 16 - x
4y = -x + 16
Divide each term by 4 and simplify
4y/4 = -x/4 + 16/4
y = -(1/4)x + 4
Using the slope intercept form ( y = mx + b ) to compare.
y = -(1/4)x + 4
Slope m = -(1/4)
Now, the equation of a perpendicular line to y = -(1/4)x + 4 must have a slope that is the negative reciprocal of the original slope.
Hence, m_perpendicular will be;
m_perpendicular = -( 1 / original slope )
m_perpendicular = -( 1 / -(1/4) )
m_perpendicular = -( -4 )
m_perpendicular = 4

If two trains leave towns 978 miles apart at the same time and travel toward each other and one train travels 21 miles per hour faster than the other and if they meet in 6 hours, then the rate of the faster and slower train will be 92mph and 71 mph respectively.
To determine the rate or speed of each train, an algebraic expression can be used.
As one train travels 21 miles per hour faster than the other, consider x to be the speed of the train that travels slower. In this case, an algebraic expression can be given as,
6x + 6(x + 21) = 978
Here, (x + 21) represents the speed of the faster train
6x + 6x + 126 = 978
12x = 978 - 126
12x = 852
x = 852 ÷ 12
x = 71
x + 21 = 71 + 21 = 92
Hence, the rate of the faster train is 92 miles per hour and the rate of the slower train is 71 miles per hour.

It exists given that the Probability of two independent event A and B exists given by P(A) and P(B).
The intersection of event A and B is given by P( A∩B).
The group of items that are part of both sets A and B is the intersection of the two sets. A ∩ B represent the intersection. The symbol "∩" can be used to represent the intersection of sets.
The collection of all outcomes that are components of both sets A and B is known as the intersection of events A and B (abbreviated AB).
