Which point is a reflection of (-4,-3) across the y-axis?
O (3, 4)
O (4, -3)
O (-3,-4)
O (4,3)
Answers
Answer:
The point after the reflection of (-4,-3) across the y-axis is:
(4, -3)Hence, option B is correct.
Step-by-step explanation:
When a point P(x, y) is reflected across the y-axis, we reverse the sign of the x-coordinate while the y-coordinate remains the same.
Thus,
The rule to reflect a point across the y-axis is:
P(x, y) → P'(-x, y)
In our case, we are given the point (-4, -3)
Let say the point is A(-4, -3)
Thus, using the rule to reflect a point across the y-axis is:
P(x, y) → P'(-x, y)
A(-4, -3) → A'(-(-4), -3) → A'(4, -3)
Therefore, the point after the reflection of (-4,-3) across the y-axis is:
(4, -3)Hence, option B is correct.

The explicit formula for the geometric progression is f ( x ) = 3 ( 4 )ˣ⁻¹
What is Geometric Progression?A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.
The nth term of a GP is aₙ = arⁿ⁻¹
The general form of a GP is a, ar, ar2, ar3 and so on
Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )
Given data ,
Let the geometric progression be represented as A
Now , the value of A is
f ( x + 1 ) = 4 f ( x )
where the second term is a₂ = 12
Now , the explicit formula is given by
f ( x ) = 3 ( 4 )ˣ⁻¹
when x = 2
f ( 2 ) = 3 ( 4 )²⁻¹
f ( 2 ) = 3 ( 4 )
f ( 2 ) = 12
Hence , the GP is f ( x ) = 3 ( 4 )ˣ⁻¹

In a class with 28 students, there are 19 boys. What is the ratio of girls to boys? 9:19 19:28 19:9 28:9
Answers
Answer:
9:19
Step-by-step explanation:
Total number of students = 28
Number of boys = 19
Number of girls = Total number of students - Number of boys = 28-19 = 9
Therefore, ratio of girls to boys = Number of girls/Number of boys = 9/19 = 9:19
Answer: 9:19
Step-by-step explanation: The total number of students is 28.
Subtract the number of boys, 19
28 - 19 = 9 girls
Use those numbers for the ratio.
girls:boys

Net pay is the difference between a worker’s gross income and his or her deductions. A person’s gross income for the year was $65,000 and their total deductions were $12,860. What was their net pay for the year? Use the formula P = I - d, where P is the net pay, I is the gross income and d is the deductions.
a. $53,140 is the net pay
b. $77,860 is the net pay
c. $72,860 is the net pay
d. $52,140 is the net pay
Answers
We are given that I = $65,000 and d = $12,860. Using the formula, we get:
P = 65000 - 12860 = 52140
So, the person's net pay is $52,140, and the answer is D.
Hope this helps.
Net pay is the amount of money your employees take home after all deductions have been taken out. This is the money they actually get on payday.

Answer:
Step-by-step explanation:
Let the exponential function for the given table is,
f(x) = a(b)ˣ
Here, f(x) = Price of the item after 'x' years
a = Initial price of the item
b = Growth factor
x = Duration(years) from year 1913
By exponential regression calculator,
Exponential function represented by the table will be,
f(x) = 7.822(1.034)ˣ
Now we have to calculate the price of the item in year 2025.
Difference in time = 2025 - 1913
= 112 years
Price of the item after 112 years,
f(112) = 7.822(1.034)¹¹²
= $330.840

A farmer wishes to determine which of two brands of baby pig pellets, Kent or Moormans, produces better weight gains. Two of his sows each give birth to litters of 10 pigs on the same day, so he decides to give the baby pigs in litter A only Kent pellets, while the pigs in litter B will get only Moormans pellets. After four weeks, the average weight gain for pigs in litter A is greater than the average weight gain for pigs in litter B. The feed they get is not the only factor affecting the rate at which pigs gain weight. Genetic differences also affect weight gain. It is likely that the pigs in litter A are genetically different from the pigs in litter B since the two litters have different mothers.
What experimental design technique could the farmer use to take into account the genetic differences?
a. Placebo
b. Blocking
c. Probability sampling
d. Double blinding
e. Observational study
Answers
Answer:
Option d (Double blinding) would be the appropriate choice.
Explanation:
A double-blind research paper would be one in which although neither group members nor even the researchers understand whose been receiving a specific intervention. This methodology has been used to protect participants throughout the research findings, which are especially beneficial throughout the prevention of bias reducing the power of personality traits or perhaps the placebo impacts.Certain other preferences are not related to just the illustration in question.

9 cans of soup and the 4 frozen dinners were purchased
Step-by-step explanation:
Let x represent the number of cans of soup purchased.
Let y represent the number of frozen dinners purchased.
Lincoln purchased a total of 13 cans of soup and frozen dinners. This means that
x + y = 13
Each can of soup has 250 mg of sodium and each frozen dinner has 550 mg of sodium. The 13 cans of soup and frozen dinners which he purchased collectively contain 4450 mg of sodium. This means that
250x + 550y = 4450 - - - - - - - - -1
Substituting x = 13 - y into equation 1, it becomes
250(13 - y) + 550y = 4450
3250 - 250y + 550y = 4450
- 250y + 550y = 4450 - 3250
300y = 1200
y = 1200/300
y = 4
Substituting y = 4 into x = 13 - y, it becomes
x = 13 - 4 = 9
