Two-Column proof for my geometry class
The two-column proof is given below:
What is meant by geometry?Mathematics' earliest branch is geometry, along with arithmetic. The distance, size, shape, and relative position of objects in relation to one another are all aspects of space that are addressed. The term "geometer" refers to a mathematician who specializes in geometry.
Before the 19th century, Euclidean geometry which incorporates the concepts of point, line, plane, distance, angle, surface, and curve as fundamental concepts—was nearly entirely the focus of geometry.
Geometry's use was greatly expanded during the 19th century by a number of discoveries. One of the first of these discoveries is Gauss Theorema Egregium, which roughly states that the Gaussian curvature of a surface is independent of any particular embedding in a Euclidean space.

4-> Perpetua has 1,800/= to buy pencils. There are 2 types which prices differ by 40/=. If she boys the cheaper type sho will get 15 more pencils than if she buys the expensive type. What are the prices of the pencils?
The price of the two pencils is Rs.100 (expensive) and Rs.60 (cheaper).
Let the price of the expensive pencil be = x
And the price of the cheaper one be = y.
According to the question:
The difference between the price of 2 = 40
Therefore,
x- y =40
Total amount = 1800.
The number of Expensive pencils that can be bought = 1800/x.
The number of Expensive pencils that can be bought = 1800/y.
According to the question,
1800/y -1800/x = 15 (the number of extra pencils)
= (1800x -1800y)/xy = 15
= 1800x -1800y =15xy
= 1800 (x-y) =15xy
Substituting x-y as 40
1800 x 40 =15xy
xy = 4800.
We know that x-y =40
Therefore, x = y+ 40
xy = 4800
(y+40) y = 4800
[tex]y^{2}[/tex] + 40 y = 4800
Using the quadratic equation formula,
y = 52.111 or y = -92.111
Thus, the cost of the cheaper pencil (y)= Rs. 52.111
The cost of the expensive pencil (x) = 52.111 + 40 = Rs 92.111
Therefore the cost of two pencils is = Rs. 52.111 and Rs 92.111.

What is the slope-intercept form of 5x 2y 10?
The slope-intercept form of a straight line of equation 5x + 2y = 10 is y = (-5/2)x + 5.
The slope-intercept form of a line is:
y = mx + b
where m is the slope of the line and b is the y-intercept (the point at which the line crosses the y-axis).
To put the equation 5x + 2y = 10 in slope-intercept form, we need to solve for y. We can do this by rearranging the terms and isolating y:
2y = -5x + 10
y = (-5/2)x + (10/2)
Thus, the slope-intercept form of the equation 5x + 2y = 10 is:
y = (-5/2)x + 5
This means that the slope of the line is (-5/2) and the y-intercept is (0,5).

Given, f(x) = [tex]x^{5}-8x^{4}-16x^{3}[/tex]
[tex]x^{5}[/tex] will also approach -∞ as x approaches -∞. This is so because a negative number remains negative when raised to the power of an odd number.[tex]x^{5}[/tex] will go closer to +∞ as x approaches +∞. This is so because the outcome is still positive when we raise a positive number to the power of an odd number.the given function's roots,f(x) = [tex]x^{5}-8x^{4}-16x^{3}[/tex]
= [tex]x^{3}[/tex](x - 4)(x - 4) = 0

What is unique array value?
A unique array value is a value that appears only once among all the other values in the given array. Hence the name unique.
What is an array?An array is a set of items, images, or numbers arranged in rows and columns. Arrays are practical illustrations of multiplication ideas.
Why do we need arrays?Arrays are needed in cases where you need to store and manipulate large amounts of data efficiently.
Some of the benefits of using arrays include:
1. Arrays allow you to store a large number of items in a single data structure, which makes it easier to work with large datasets.
2. Arrays allow you to access and modify the items in the array quickly, using the index of the item.
A data structure called an array is used to hold a number of elements together. Each item in an array is recognized by its index, or place within the array. A value that only appears once in an array is considered to be unique array value. Think about the following array, for instance:
[1, 2, 3, 4, 5, 6]
Because each value only occurs once in this array, each value is distinct.
Contrarily, think about the following array:
[1, 2, 3, 3, 4, 5]
Since it appears twice in this array, the number 3 is not unique. Since they only exist once, each of the other values is distinct.

The factors of [tex]2x^2 + 7x + 15[/tex] are [tex](2x + 3)[/tex] and [tex](x + 5)[/tex].
To find the factors of [tex]2x^2 + 7x + 15[/tex] , we can use the factoring method called "splitting the middle term." Here's how it works:
Write the expression as the product of two binomials: [tex](2x^2 + 7x + 15) = (2x^2 + ax + b)(cx + d)[/tex]
Find the factors of the constant term (15) that add up to the coefficient of the middle term (7). The factors of 15 are 1 and 15, 3 and 5, and 5 and 3. The only pair that adds up to 7 are 3 and 5.
Set the coefficients of the two binomials to 3 and 5, respectively. The expression becomes: [tex](2x^2 + 3x + 5)(5x + 3)[/tex]
Rewrite the binomials using the distributive property: [tex](2x^2 + 3x + 5)(5x + 3) = (2x^2 + 5x + 3x + 15) = 2x(x + 5) + 3(x + 5) = (2x + 3)(x + 5)[/tex]

What is the end behavior of the graph of f x x5 8x4 16x3?
The end behavior of the graph of f(x) = x^5 + 8x^4 + 16x^3 is asymptotic: it goes towards positive infinity as x approaches positive infinity, and negative infinity as x approaches negative infinity.
The end behavior of the graph of a polynomial function with degree 5 is determined by the leading term, which in this case is x^5. Since the degree of the leading term is odd and the coefficient is positive, the graph of f(x) = x^5 + 8x^4 + 16x^3 will approach positive infinity as x approaches positive infinity, and negative infinity as x approaches negative infinity. This is known as an asymptotic end behavior. As the x-values get larger and larger, the magnitude of the y-values will also get larger and larger, approaching infinity in either direction. This can be seen by looking at the graph of the function, which will have an "S" shape that curves up and to the right (positive infinity) for large positive x-values, and down and to the left (negative infinity) for large negative x-values.
For x > 0, the end behavior is:
f(x) = x5 + 8x4 + 16x3
lim x→∞ f(x) = lim x→∞ x5 + 8x4 + 16x3
lim x→∞ f(x) = lim x→∞ x5
lim x→∞ f(x) = +∞
For x < 0, the end behavior is:
f(x) = x5 + 8x4 + 16x3
lim x→−∞ f(x) = lim x→−∞ x5 + 8x4 + 16x3

If a and b are both negative numbers and a>b, what must be true about their absolute values?.
The absolute value of a number is the non-negative distance between the number and zero on a number line, regardless of sign.
This means that the absolute value of a negative number is always positive. Therefore, if a and b both are negative numbers, their absolute values will be positive numbers. If a is greater than b, then the absolute value of a must be greater than the absolute value of b. This can be expressed mathematically as follows:
|a| > |b|
This equation states that the absolute value of a is greater than the absolute value of b. In other words, the distance between a and zero is greater than the distance between b and zero on a number line.
To illustrate this, let’s take an example of two negative numbers, a=-3 and b=-5. The absolute values of these two numbers are 3 and 5 respectively. Since 3 is greater than 5, the absolute value of a is greater than the absolute value of b. This holds true regardless of the sign of the numbers, as long as a is greater than b.

If f(x) has a y-intercept at 3 and x-intercepts at 2 and −4, and if
g(x) = 2f(2x + 3), which intercepts of g(x) can you identify for certain, and what are they?
Answer:
Step-by-step explanation:
The y-intercept of g(x) is 3 * 2 = 6.
To find the x-intercepts of g(x), we need to find the values of x that make g(x) equal to 0. Since g(x) = 2f(2x + 3), this means we need to find the values of x that make f(2x + 3) equal to 0. Therefore, we can find the x-intercepts of g(x) by solving the equation f(2x + 3) = 0 for x.
Since the x-intercepts of f(x) are at 2 and -4, this means that the equation f(x) = 0 has solutions at x = 2 and x = -4. Substituting these values into the equation f(2x + 3) = 0, we get:
f(2(2) + 3) = 0
f(4 + 3) = 0
f(7) = 0
and
f(2(-4) + 3) = 0
f(-8 + 3) = 0
f(-5) = 0
Therefore, the x-intercepts of g(x) are at x = 7/2 and x = -5/2. These are the only intercepts of g(x) that we can determine for certain.

During optimal conditions, the rate of change of the population of a certain organism is proportional to the population at time t, in hours. At time t=0 hours, the population is 300. At time t=24 hours, the population is 1000. At what time t is the population 500 ?.
The time t at which the population is 500 is 45 hours.
The equation gives the rate of change of the population at time t:
dP/dt = kP
where P is the population at time t and k is the constant of proportionality.
We can use this equation to find the value of k by substituting the known values of P and t at time t=24 hours:
dP/dt = kP
1000 = k*300
k = 1000/300
k = 10/3
Now that we know the value of k, we can use the equation to find the time t at which the population is 500:
dP/dt = kP
500 = (10/3)P
P = 500*3/10
P = 150
Since the population at time t=0 hours is 300, the population has decreased by 150 over the 24 hours, so t = -150/(-10/3) = 45 hours.
Therefore, the time t at which the population is 500 is 45 hours.

dP/dt = kP
We can use this equation to find the value of k by substituting the known values of P and t at time t=24 hours:
dP/dt = kP
1000 = k*300
k = 1000/300
k = 10/3
dP/dt = kP
500 = (10/3)P
P = 500*3/10
P = 150
Since the population at time t=0 hours is 300, the population has decreased by 150 over the 24 hours, so t = -150/(-10/3) = 45 hours.
Therefore, the time t at which the population is 500 is 45 hours.
3. Indrani and Jagad share some money in the ratio Indrani: Jagad = 7:9. Calculate the percentage of the money that Indrani receives.
The percentage of money Indrani receives is 43.75%.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, Indrani and Jagad share some money in the ratio,
Indrani : Jagad = 7 : 9.
We know the percentage of money for both a and b in the form of a : b can be obtained as, [a/(a + b)]×100.
Therefore, the percentage of money Indrani gets is,
= [7/(7 + 9)]×100.
= (7/16)×100.
= 43.75%.

Answer:
43.75%
Step-by-step explanation:
Find the nth term of the following sequences. Also find the 9th and 6th terms .
Answer: an=2(-2)ⁿ⁻¹ a₉=512 a₆=-64
Step-by-step explanation:
Since we have an alternating minus sign in this sequence, therefore the first multiplier of the following sequence will be (-1)ⁿ.
And since the first term of the following sequence is positive, the first multiplier of the following sequence is (-1)ⁿ⁻¹.
The second multiplier of the following sequence is 2ⁿ because the sequence has the form: 2, 4, 8, 16, ..., 2ⁿ .
[tex]Thus,\ a_n=(-1)^{n-1}(2^n)\\\\ a_n=2(-2)^{n-1}\ \ \ (1)[/tex]
Find the 9th and 6th terms of the sequence by formula (1):
a₉=2(-2)⁹⁻¹
а₉=2(-2)⁸
a₉=2(256)
a₉=512
a₆=2(-2)⁶⁻¹
а₆=2(-2)⁵
a₆=2(-32)
a₆=-64
