What is a translation?In Mathematics, the translation a geometric figure or graph to the left simply means subtracting a digit from the value on the x-coordinate of the pre-image while the translation a geometric figure or graph downward simply means subtracting a digit from the value on the y-coordinate (y-axis) of the pre-image.
Next, we would apply a translation to each of the points as follows;
Point 1 (1, 2) → (x - 5, y - 4) = (1 - 5, 2 - 4) = Point 1' (-4, -2).
Point 2 (2, 4) → (x - 2, y - 3) = (2 - 2, 4 - 3) = Point 2' (0, 1).
Point 3 (4, 4) → (x + 1, y - 4) = (4 + 1, 4 - 4) = Point 3' (5, 0).
Point 4 (3, 2) → (x - 3, y - 2) = (3 - 3, 2 - 2) = Point 4' (0, 0).

there are about 1,265 school districts in the state of texas that generate an equivalent expression using prime factorization for the number 1,265
pls, help whoever answers first gets brainliest!!
Answer:
1265 = 5*11*23------------------------------------------
Find prime factors of 1265.
We see it is divisible by 5 since ends with 5:
1265/5 = 253253 is not divisible by 3 or 9 since the sum of digits is not divisible by 3 or 9. It is not divisible by 7 (since 25 - 3*2 = 19 is not divisible by 7) but divisible by 11, since the sum of digits in odd places is same as the digit in the even place (recall divisibility by 11):
253/11 = 2323 is a prime number so no more factors.
Hence the prime factorization of 1265 is:
1265 = 5*11*23Marshall is looking at the key on a map. According to the key, 1 inch = 24 miles. Marshall measures the
distance between 2 cities on the map and discovers they are 11.5 inches apart. How many miles apart are the two cities?
A. 276 miles apart
B. 210 miles apart
C. 249 miles apart
D. 294 miles apart
Answer:
A. 276 miles apart
Step-by-step explanation:
We have the information that if two cities are 1 inch apart then the distance between them is 24 miles.
If it is 11.5 inches apart, then we should multiply the 24 miles per inch by 11.5
24 miles / 1 inch
(24 miles / 1 inch) * 11.5 inches
Inches cancel so you are left with
24 * 11.5 = 276 miles

a manufacturer conducted a survey to determine how many people buy products p and q. what fraction of the people surveyed said that they buy neither product p nor product q ?
The fraction of the people surveyed that said that they buy neither product p nor product q is 1/6.
It is given to us that -
A survey is conducted with the number of people buying products p and q
We have to find out the fraction of the people surveyed said that they buy neither product p nor product q.
From the given information, the total number of products can be represented as -
[Total products bought] = [p products bought] + [q products bought] - [both p and q bought] + [neither p and q bought] ---- (1)
We have to find out -
[neither p and q bought]/[Total products bought]
Let us assume that the total products bought = 6
It is known that 1/3 of the people surveyed said that they buy product p but not product q.
=> [p products bought] - [both p and q bought] = 1/3 * 6
=> [p products bought] - [both p and q bought] = 2 ------ (2)
From equation (1), we can say that -
[Total products bought] = [p products bought] + [q products bought] - [both p and q bought] + [neither p and q bought]
=> 6 = ([p products bought] - [both p and q bought]) + [q products bought] + [neither p and q bought]
From equation (2), we can write the above equation as -
=> 6 = 2 + [q products bought] + [neither p and q bought]
=> [q products bought] + [neither p and q bought] = 4 ------ (3)
Again, it is also known that 1/2 of the people surveyed said that they buy product q.
=> [q products bought] = 1/2 *6
=> [q products bought] = 3 ---- (4)
From equation (3) and equation (4), we can say that -
[q products bought] + [neither p and q bought] = 4
=> 3 + [neither p and q bought] = 4
=> [neither p and q bought] = 1 ------ (5)
From equation (5) and the total number of products bought, we can say that -
[neither p and q bought]/[Total products bought] = 1/6
(Since, the total number of products bought = 6)
Therefore, the fraction of the people surveyed that said that they buy neither product p nor product q is 1/6.

Machine fills rate 135 containers per minute how long will it take to fill 1000 containers at the same rate
At the rate of 135 containers per minute, it will take approximately 7.4 minutes to fill 1000 containers.
To determine the time it takes to fill 1000 containers, we need to divide the number of containers by the rate at which they are filled. In this case, we have 1000 containers and a filling rate of 135 containers per minute, so we divide 1000 by 135 to find the time it takes to fill the containers:
1000 containers / 135 containers/minute = 7.40740740740741 minutes
Since a minute cannot be divided into fractions, we must round the result to the nearest whole number. This means that it will take approximately 7.4 minutes to fill 1000 containers at a rate of 135 containers per minute.
The machine will take 7.41 minutes (approx) to fill 1000 Containers.
Time taken to fill 135 Containers= 1 minute ...............(Given)
Time taken to fill 1 Container= 1/135 minute
Time taken to fill 1000 Containers = 1000 × 1/135 minutes
= 1000/135 minutes
= 200/27 minutes
≈ 7.41 minutes.
Thus, The machine will take 7.41 minutes (approx) to fill 1000 Containers.

what lurking variables might be causing the increase in one or both of the variables? explain your answer.
A lurking variable is an explanatory variable that was not examined in a study but has an effect on the value of the study's response variable.
A concealed variable affects both the dependent and independent variables, resulting in an incorrect connection. Confounding is a causal concept that cannot be expressed using correlations or linkages. Confounders have a significant quantitative role in explaining why correlation does not imply causation.
In the case of risk assessments assessing the degree and form of threat to human health, it is critical to account for confounding in order to isolate the impact of a specific hazard such as a food additive, pesticide, or new drug.

(a) The quadratic equation (x+2)² +3k-1=0 has two real and distinct roots, where k is a constant. Find the range of values of k.
Answer: This means that the range of values of k is k ∈ [-1/3, 1/3].
Step-by-step explanation: The quadratic equation (x+2)² +3k-1=0 can be written as (x+2)² = 1-3k. For the equation to have two real and distinct roots, the expression under the square root must be nonnegative. Therefore, we have the inequality 1-3k ≥ 0. Solving this inequality gives us -1/3 ≤ k ≤ 1/3. This means that the range of values of k is k ∈ [-1/3, 1/3].

If AB has endpoint A(2, 13) and midpoint
(10,-1) then give the coordinate of B.
Answer:
(18, -15)
Step-by-step explanation:
The vector AB is defined by its starting and endpoints. Usually, B would be at the end, but in this case A is. Since we are given its midpoint, that is, the point equidistant from both the coordinates A and B, we can find coordinate B by simply calculating the distance between A and the midpoint and reapplying this distance to the midpoint.
1. Finding the distance between the midpoint and A:
The distance between two coordinates, from what I can recall, is simply the final coordinate value minus the initial coordinate value, following the form (x2-x1, y2-y1). We know that A comes after the midpoint, because it is the endpoint (so it will be the final coordinate value). Applying this to the context of the question, (2-10, 13+1) = (-8,14).
2. Finding B using the distance between midpoint and A:
B will be the initial coordinate value because it comes before the midpoint. Therefore, giving B the values (x,y): (10-x, -1-y) = (-8, 14). Separating into two equations (respective to each axis):
10-x=-8
-x=-18
x=18
-1-y=14
-y=15
y=-15
Therefore, the coordinate of B is (18, -15).

The quantity for the two equations is; 400
How to find the equilibrium price?
The equilibrium price formula is based on the demand and supply quantities; you will set quantity demanded (Qd) equal to quantity supplied.
The equilibrium price definition above is one that tells us that there is a price point that meets the needs of both supply and demand. In order to understand when those needs are met, we need to know how to find equilibrium price.
We are given;
Quantity supplied; S(p) = -200 + 50p
Quantity demanded; D(p) = 1060 - 55p
Thus, equilibrium price is p when;
S(p) = D(p)
-200 + 50p = 1060 - 55p
1060 + 200 = 55p + 50p
1260 = 105p

= [tex]2\int r - r[2(4r^2-y^2)]dy[/tex]
= [tex]4\int r - r(4r^2-y^2)dy[/tex]
= [tex]4(4r^2y-y^3/3)r-r[/tex]
= [tex]4(4r^2(r+r)-(r^3+r^3)/3)[/tex]
= [tex]4((4r^2)(2r)-2r^3/3)[/tex]
= [tex]8(4r^3-r^3/3)[/tex]
= [tex](8)(12r^3-r^3)/3[/tex]
= 88[tex]r^3[/tex]/3
Thus, the volume of cylinders is (88r^3)/3.
You question is incomplete, but most probably your full question was
find the volume of the given solid. bounded by the cylinders [tex]x^2 + y^2 = 4r^2[/tex], [tex]y^2 + z^2 = 4r^2[/tex]
