Point T' has coordinates (-3, 4). If it was translated up 3 units, what were the coordinates of its pre-image?
(0, 4)
(-3, 7)
(-3, 1)
(-6, 4)
Answers
Translations are base on the rule (x,y) -- (x+a, y+b) where the words right and left represent the change in the x-axis, and the words up and down the change in the y-axis.
In this exercise it is asked you to find the coordinates of the preimage of point T', which has the coordinates (-3,4) and is the effect of a translation of 3 units up. As previous said, the words up and down represent a change on the y-axis, meaning that the y-coordinate is the one that should be changed.
If the translation from the preimage to the image was 3 units up, then the preimage can be found by subtracting three units.
Pre-image: (-3,4-3)= (-3,1)
The point that represents the coordinates of the pre-image is (-3,1).
Answer: the answer is (-3, 1)

A football stadium holds 52,000 fans. A college student is doing research and determines that on any given game day, the home team has five times as many fans as the visiting team. In order to help the student in his research, he represents the number of home team tickets as H and the visiting team’s tickets as V.
Answers
Based on this data, we can find the number of number of fans of each team.
Following data has been provided:
1) Total number of fans stadium can hold = 52000
So on a given day if stadium is full,
H + V = 52000
2) Home team has 5 times as many fans as the visiting team.
So,
H = 5V
Using the value of H in first equation, we get:
5V + V = 52000
6V = 52000
V = 8667 fans
H + V = 52000
⇒
H = 52000 - V = 52000 - 8667 = 43333 fans
So,
there will be 43,333 fans of home team and 8667 fans of visiting team.
how to do midpoint and distance formula
Answers
hopes this helped
Final answer:
The midpoint formula calculates the center point between two points on a coordinate plane, while the distance formula calculates the distance between two points using the Pythagorean theorem.
Explanation:
Understanding the Midpoint and Distance Formulas
The midpoint formula is used to find the exact center point between two defined points on a coordinate plane. To find the midpoint (M) between two points, (X1, Y1) and (X2, Y2), you use the formula:
M = ((X1 + X2) / 2, (Y1 + Y2) / 2)
For example, to find the midpoint between the points (2, 3) and (4, 8), you would calculate:
M = ((2 + 4) / 2, (3 + 8) / 2) = (3, 5.5)
The midpoint between these points is at coordinates (3, 5.5).
The distance formula, on the other hand, is used to determine the distance between two points on a coordinate plane.
The formula is derived from the Pythagorean theorem and is written as:
D = \(√((X2 - X1)^2 + (Y2 - Y1)^2)\)
Using the above points, the distance (D) would be:
D = \(√((4 - 2)^2 + (8 - 3)^2)√ = \(√(4+25) = \(√29\)√
The distance between the two points is the square root of 29.
Practicing these formulas enhances your problem-solving skills and helps in many areas of mathematics, including geometry and algebra.

True: If it is a function
False: If it is not a function
{(2, 3), (4, 5), (4, 3), (3, 4)}
Answers
Explanation:
The given relation does not fit the definition of function.
A function is a relationship that states unambigously the image (output) of the input (independent) variable.
In the set of ordered pairs it is true form the input-values 2, and 3, because their images are 3 and 4, respectively.
But, could you tell the image of 4?. It may be 5 or 3. That is an ambiguity. That is why the given relationship is not a function.
This means if more than one ordered pairs will have the same first component, the relation will not be a function.
In the given relation, the first component of 2nd and 3rd ordered pair is the same, so the relation {(2, 3), (4, 5), (4, 3), (3, 4)} is not a function.
So the Answer is False.

The question is:
[tex] \frac{d^2+d-30}{d^2+3d-40} + \frac{d^2+14d+48}{d^2-2d-48} [/tex]
1) Start factoring all the polynomials to rewrite the fractions.
2) d^2 + d - 30 = (d + 6)(d - 6)
3) d^2 + 3d - 40 = (d + 8)(d - 5)
4) d^2 + 14d + 48 = (d + 6) (d + 8)
5) d^2 - 2d - 48 = (d - 8)(d + 6)
6) rewrite the fractions:
(d+6)(d-5) (d+8)(d+6)
----------------- + -----------------
(d+8)(d-5) (d-8)(d+6)
7) simplify the fractions cancelling the factors that are equal in the numerator and the denominator:
d+6 d+8
-------- + -------
d+8 d-8
8) take least common denominatior: (d+8)(d-8), and sum the fractions:
(d-8)(d+6) + (d+8)^2
--------------------------------
(d+8)(d-8)
9) expand the parenthesis in the numerator and combine like terms:
d^2 - 2d - 48 + d^2 + 16d + 64
------------------------------------------- =
(d+8)(d-8)
2d^2 + 14d + 16
= ----------------------------
(d+8)(d-8)

How many positive integers between 100 and 999 inclusive are divisible by three or four?
Answers
There are 900 numbers between 100 and 999 (inclusive)
We group the numbers into groups of 3s. So we find one number divisible by 3 in every group.
Number of numbers that can be divided by 3 = 900 ÷ 3 = 300
Number of numbers that can be divided by 3 = 300
We group the numbers into groups of 4s. So we find one number divisible by 4 in every group.
Number of numbers that can divided by 4 = 900 ÷ 4 = 225
Number of numbers that can divided by 4 = 225
Among the group of 4s, there is 1/3 that are already inclusive in divisible by 3.
225 ÷ 3 = 75
Number of numbers that can divided by 4 = 225 - 75 = 150
Total numbers of positive integers divisible by three and fours = 300 + 150 = 450
The total number of positive integers between 100 and 999 inclusive that are divisible by 3 or 4 is 450.
Explanation:The problem is looking for positive integers between 100 and 999 inclusive, that are divisible by three or four. First, we find out how many numbers between 100 and 999 are divisible by 3 by using the formula: (Last Numbers - First Number) divided by the number you are dividing + 1. Hence, [tex](999 - 102) / 3 + 1 = 300.[/tex] Similarly, for numbers divisible by 4: (996 - 100) / 4 + 1 = 225. However, we must subtract out the numbers that are counted twice because they are divisible by both 3 and 4 (i.e., divisible by 12). To find this, we do [tex](996 - 108) / 12 + 1 = 75.[/tex]
In conclusion, we add the numbers divisible by 3 and those divisible by 4 and subtract the ones that are divisible by both (12). Hence, the total number of positive integers between 100 and 999 inclusive that are divisible by 3 or 4 is [tex]300 + 225 - 75 = 450.[/tex]

Find the coefficient of x 4 in the taylor series expansion centered at the origin for the function f(x) = 8 ln(9 + 3x 2 ).
Answers
Note, that it is the full solution, it is possible to make it shorter.
The coefficient of x4 in the Taylor series expansion of the given function is 0.
Explanation:To find the coefficient of x4 in the Taylor series expansion of the function f(x) = 8 ln(9 + 3x2), we need to compute the fourth derivative of f(x) and evaluate it at x = 0.
The Taylor series expansion for a function centered at the origin is given by:
f(x) = f(0) + f'(0)x + f''(0)x2/2! + f'''(0)x3/3! + f''''(0)x4/4! + ...
In this case, we have:
f'''(x) = 48x/(9 + 3x2)
Evaluating f'''(x) at x = 0 gives:
f'''(0) = 0/9 = 0
Therefore, the coefficient of x4 in the Taylor series expansion centered at the origin for the function f(x) = 8 ln(9 + 3x2) is 0.

We have,
To determine how much you need to deposit today, we can use the concept of present value (PV).
The present value represents the current value of a future cash flow, accounting for the time value of money and the expected interest rate.
In this case, you want to have $31,664 in cash in 4 years, and you expect to earn an annual interest rate of 11.5%.
Let's calculate the present value using the following formula:
[tex]PV = FV / (1 + r)^n[/tex]
where PV is the present value, FV is the future value, r is the interest rate per period, and n is the number of periods.
Plugging in the values, we have:
[tex]PV = $31,664 / (1 + 0.115)^4[/tex]
Calculating this equation, we find:
[tex]PV = $31,664 / (1.115)^4[/tex]
= $31,664 / 1.530749
PV ≈ $20,701.27
Therefore,
You would need to deposit approximately $20,701.27 today if this is the only money you save for the purpose of buying a car in 4 years, considering an expected annual interest rate of 11.5%.

Given
x^2 = –5x + 8
First, put all terms in the left side of the equal sign, as follows:
x^2 + 5x - 8 = 0
Then, use the quadratic formula with a = 1 (the coefficient of the quadratic term), b = 5 (the coefficient of the linear term) and c = -8 (the independent term).
[tex]x = \frac{-b \pm \sqrt{b^2 - 4(a)(c)}}{2(a)}[/tex]

it can be noted that whilst the x coordinates remain the same in the final image, y coordinate values, the sign changes.
eg: A (x = -7) and A' (x = -7)
therefore x coordinates haven't changed the value nor sign
A (y = 1) and A' (y = -1)
y coordinates have been multiplied by -1 hence changing the sign.
the reflection goes as (x,y) = (x,-y)
this is a reflection over the x axis.
each picnic table seats 6 people how many picnic tables are needed to seat 24 people?
Answers
Final answer:
To seat 24 people at picnic tables that each seat 6, you divide 24 by 6, which equals 4 tables needed.
Explanation:
The question is asking how many picnic tables are needed to seat 24 people, if each table seats 6 people. This is a division problem where we need to divide the total number of people by the number of seats at a single table. You divide 24 (the total number of people) by 6 (the number of seats at one table) to find out the number of tables needed.
Here is the calculation: 24 \/ 6 = 4. Therefore, you would need 4 picnic tables to seat 24 people, assuming each person takes one seat and that there are no empty seats.
