The inverse of function f(x) = x +3 is y=x−3
Step-by-step explanation:
To find the inverse function, swap x and y, and solve the resulting equation for x.
If the initial function is not one-to-one, then there will be more than one inverse.
So, swap the variables: y=x+3 becomes x=y+3.
Now, solve the equation x=y+3 for y.
y=x−3
A company manufactures products in patches of 200 on one machine . If the company works 8 hours per day, 5 days per 5 a) the Production Capacity per week if the setup time is 3hrs and the cycle time is 1.5 minutes
The Production Capacity per week if the setup time is 3 hours and the cycle time is 1.5 minutes is 1110 products.
Calculate the Production capacity per week with the help of the following formula;
Production Capacity = ((60 / Cycle Time) * Hours per day * Days per week) - (Hours of maintenance / Hours per week)
As given, Cycle time = 1.5 minutes, Working hours per day = 8 hours, Working days per week = 5 days, Hence,
Working hours per week = Working hours per day × Working days per week
= 8 hours × 5 days
= 40 hours
Setup time = 3 hours, Therefore, Maintenance hours per week = Setup time = 3 hours
Now, Production Capacity = ((60 / 1.5) × 8 × 5) - (3 / 40)= (240 × 5) - 0.075×(240 × 5)
= 1200 - 90
= 1110 products

Which of the following search algorithms should be used on large arrays if speed if important?
BinaryascendingBubble sortAll of the above
If speed is important and the array is large, the a. Binary search algorithm should be used. This algorithm is designed to efficiently search through sorted arrays by repeatedly dividing the search interval in half.
It has a time complexity of O(log n), which means that as the size of the array increases, the time it takes to search for an item will not increase at the same rate.
On the other hand, ascending bubble sort and other sorting algorithms such as selection sort and insertion sort have a time complexity of O(n^2), which means that as the size of the array increases, the time it takes to sort the array will increase exponentially. Therefore, these algorithms are not efficient for large arrays and should not be used if speed is important.
In summary, when dealing with large arrays and speed is important, binary search is the best algorithm to use for searching, while ascending bubble sort and other sorting algorithms with a time complexity of O(n^2) should be avoided.

How do you find the limit of a function on a calculator?
Answer:
Step-by-step explanation:
The method for finding the limit of a function on a calculator depends on the specific calculator you are using. Here are the general steps for finding the limit of a function using a graphing calculator:
Enter the function: Most graphing calculators have a function editor where you can enter the function you want to find the limit of.
Set the limit: To find the limit of the function at a particular point, you need to specify the value at which you want to find the limit. This is done by entering the limit expression, for example: limit(f(x), x, a) where f(x) is the function, x is the variable, and a is the value at which you want to find the limit.
Evaluate the limit: After entering the limit expression, you can evaluate it by pressing the "enter" or "=" button. The calculator will then display the limit of the function at the specified value.
It's important to note that a graphing calculator can only estimate the limit of a function based on the accuracy of the graph, so the result may not be exact. Additionally, some functions may have limits that cannot be evaluated using a calculator. In these cases, you may need to use analytical methods to determine the limit.

The real exchange rate of Canada increased by 4.9% relative to US. Observing that Canada's inflation rate is 8.5% while the US inflation rate is 3.8%, what is the change in the nominal exchange rate (in Canada's perspective)? Round your answer to the nearest two decimal place. Write your answer in percentage terms so if your answer is 10%, write 10 .
The change in the nominal exchange rate, in Canada's perspective, is a depreciation of the Canadian dollar by 2.76%.
Nominal exchange rate is the price of one currency in terms of another currency. It represents the number of units of one currency that can be purchased with a single unit of another currency. In Canada's perspective, a change in nominal exchange rate means the value of the Canadian dollar in US dollars. So, to calculate the change in nominal exchange rate from Canada's perspective.
Nominal Exchange Rate = Real Exchange Rate x (1 + Inflation of Canada) / (1 + Inflation of US) Given, Real Exchange Rate of Canada
= 4.9% Inflation of Canada
= 8.5% Inflation of US
= 3.8% Nominal Exchange Rate
= 4.9% x (1 + 8.5%) / (1 + 3.8%) Nominal Exchange Rate
= 4.9% x 1.085 / 1.038 Nominal Exchange Rate
= 5.3099 / 1.038 Nominal Exchange Rate
= 5.11 (rounded to two decimal places)
This means that if there were no inflation, the nominal exchange rate from Canada's perspective would have been 5.11 Canadian dollars per US dollar. But due to inflation, the Canadian dollar depreciated by 2.76% (calculated as (5.11 - 4.97) / 5.11 x 100%). Therefore, the change in the nominal exchange rate, in Canada's perspective, is a depreciation of the Canadian dollar by 2.76%.

A line is perpendicular to y = -1/5x + 1 and intersects the point negative (-5,1) what is the equation of this perpendicular line?
Answer: y = 5x + 26
Step-by-step explanation:
To find the equation of a line that is perpendicular to the given line y = -1/5x + 1 and passes through the point (-5, 1), we need to determine the slope of the perpendicular line. The given line has a slope of -1/5. Perpendicular lines have slopes that are negative reciprocals of each other. So, the slope of the perpendicular line will be the negative reciprocal of -1/5, which is 5/1 or simply 5. Now, we have the slope (m = 5) and a point (-5, 1) that the perpendicular line passes through.
We can use the point-slope form of a linear equation to find the equation of the line:
y - y1 = m(x - x1)
Substituting the values, we get:
y - 1 = 5(x - (-5))
Simplifying further:
y - 1 = 5(x + 5)
Expanding the brackets:
y - 1 = 5x + 25
Rearranging the equation to the slope-intercept form (y = mx + b):
y = 5x + 26
Therefore, the equation of the perpendicular line that passes through the point (-5, 1) is y = 5x + 26.

The poll conducted among 1755 internet users indicates that a portion of them have posted a photo or video online. However, it is not possible to definitively conclude whether more than half of internet users have done so based solely on this survey.
The poll results show that a specific percentage of the surveyed internet users have posted a photo or video online. However, it is important to note that the sample size of 1755 users might not represent the entire population of internet users accurately. The survey participants might not be a diverse and representative sample, which can introduce biases. Additionally, there may be various reasons why some internet users choose not to share photos or videos online, such as privacy concerns, lack of interest, or limited access to technology. Therefore, while the poll provides insights into the habits of the surveyed individuals, it is not sufficient to draw a conclusive statement about the behavior of all internet users.

Elena is paid a constant rate for each hour she works. The table shows the amounts of money that Elena earned for various amounts of
time that she worked.
Constant rates are used to illustrate linear functions.
The average rate of change is $9.0 per hourThe function that models the table is: \(\mathbf{f(x) = 9x }\)The amount earned in 7.5 hours is $67.5(a) The average rate of change
This is calculated using:
\(\mathbf{Rate = \frac{y_2 -y_1}{x_2 -x_1}}\)
So, we have:
\(\mathbf{Rate = \frac{31.5-22.50}{3.5 - 2.5}}\)
\(\mathbf{Rate = \frac{9}{1.0}}\)
\(\mathbf{Rate = 9.0}\)
Hence, the average rate of change is $9.0 per hour
(b) A function that models the table of values
Let x represent hours, and y represent the earnings.
So, we have:
\(\mathbf{y =m (x - x_1) + y_1}\)
Where:
m =Rate = 9.0
So, we have:
\(\mathbf{y = 9(x - 2.5) + 22.5}\)
Expand
\(\mathbf{y = 9x - 22.5 + 22.5}\)
\(\mathbf{y = 9x }\)
Represent as a function
\(\mathbf{f(x) = 9x }\)
Hence, the function that models the table is: \(\mathbf{f(x) = 9x }\)
(c) Amount earned for 7.5 hours
This means that x = 7.5
So, we have:
\(\mathbf{f(7.5) = 9 \times 7.5 }\)
\(\mathbf{f(7.5) = 67.5}\)
Hence, the amount earned in 7.5 hours is $67.5
