Answers
Exponential growth is a type of growth that occurs when the rate of increase is proportional to the current amount.
Logarithmic evaluationLog√7 = 1.659Log 23/6 = 0.862It is a rapid increase in the quantity of something over a period of time. Exponential growth can be seen in populations, investments, and other areas.It is characterized by a doubling or tripling of the original amount within a specified period of time.This type of growth is often caused by compounding, where gains from one period are reinvested in the next period, leading to a rapid increase in the overall amount.Exponential growth is often seen in the early stage of a business, when it is experiencing rapid growth due to investments or other factors.However, exponential growth can also lead to rapid decline if not managed properly.This is called logarithmic evaluation, which involves using logarithms to simplify complex expressions.To learn more about logarithmic evaluation refer to:

Answers
the missing functions in the piecewise function are f(x) = - x - 4 for - 6 ≤ x ≤ - 1, f(x) = 4 for 1 < x ≤ 2 and f(x) = - 1 / 2 x - 6 for 2 < x ≤6.
We are given the graph of a piecewise function.
We need to complete the function to represent the graph completely.
We know that, a piecewise function is a function that has different functions for a particular set of values for x.
Here, we can see that:
For the values of x in between - 6 and - 1 that is - 6 ≤ x ≤ - 1, we get the function as:
f(x) = - x - 4
For the values of x in between - 1 and 2 that is - 1 < x ≤ 2, we get the function as:
f(x) = 4
For the values of x in between 2 and 6 that is 2 < x ≤6, we get the function as:
f(x) = - 1 / 2 x - 6
Therefore, we get that, the missing functions in the piecewise function are f(x) = - x - 4 for - 6 ≤ x ≤ - 1, f(x) = 4 for 1 < x ≤ 2 and f(x) = - 1 / 2 x - 6 for 2 < x ≤6.

The equation for a transformed cosine wave with the following properties is y = 3cos2x + 4
Equation of transformed cosine wave:An equation for a transformed cosine wave with the following properties can be written in the form:
y = A× cos(B(x - C)) + D
Where:
A = amplitude (positive value)
C = phase shift (horizontal shift of the wave)
D = vertical shift (shift of the wave up or down)
Here we have
Amplitude = 3
Period = π
Horizontal shift = None
Vertical shift = 4 units up
As we know Period P = 2π/B
From the data => 2π/B = π
=> B = 2
Hence,
Equation for a transformed cosine wave, y = 3 × cos(2(x - 0)) + 4
=> y = 3 × cos(2(x )) + 4
=> y = 3cos2x + 4
Therefore,
The equation for a transformed cosine wave with the following properties is y = 3cos2x + 4

HI PLEASE HELP ON QUESTION ASAP USING AVERAGE (MEAN) TO ANSWER QUESTION! IF UR ANSWER AND EXPLAINATION IS CORRECT ILL RATE YOU FIVE STARS, A THANKS AND MAYBE EVEN BRAINLIEST. PLEASE MAKE SURE YOU ANSWER MY QUESTION USING AVERAGES.
1) a meal for 6 cost £12 per person. as it is one of the diners birthday , the other 5 decided to pay for his meal. how much do each of the five friends need to pay?
Answers
Each of the five friends needs to pay £14.40 to cover the cost of the birthday person's meal.
To calculate how much each of the five friends needs to pay, we can use the concept of averages or mean.
The total cost of the meal for 6 people is £12 per person. This means that the total cost of the meal is 6 * £12 = £72.
Since the other five friends have decided to pay for the birthday person's meal, they will evenly divide the total cost of £72 among themselves.
To find the average amount each friend needs to pay, we divide the total cost by the number of friends paying, which is 5:
£72 / 5 = £14.40
Using the concept of averaging or finding the mean allows us to distribute the cost equally among the friends, ensuring fairness in sharing the expenses.

} One number is 8 times another. When the lesser number is subtracted from the greater, the result is 2 more than 5 times the lesser number. What are the numbers?
Answers
The numbers are 1 and 8.
We have,
Let's assume the lesser number as "x" and the greater number as "8x".
According to the given information, when the lesser number is subtracted from the greater, the result is 2 more than 5 times the lesser number:
8x - x = 5x + 2
Simplifying the expression:
7x = 5x + 2
Subtracting 5x from both sides:
2x = 2
Dividing both sides by 2:
x = 1
So, the lesser number is 1 and the greater number is 8 times that, which is 8.
Therefore,
The numbers are 1 and 8.

From the chart, estimate (roughly) the number of transistors per IC in 2016. Using your estimate and Moore's Law, what would you predict the number of transistors per IC to be in 2040?
Please explain
Answers
The estimates for the number of transistors per IC, using an exponential function, are given as follows:
2016: 16,777,216,000.2040: 6.87 x 10¹³.What is the format of an exponential function?An exponential function has the general format presented as follows:
\(y = ab^\frac{x}{n}\)
In which the parameters of the function are listed as follows:
a is the initial value of the function.b is the rate of change of the function.n is the period relative to the rate of change.By Moore's Law, the number of transistors per IC doubles every two years, hence the values of parameters b and n are both two, that is:
b = 2, n = 2.
We take 1972 as the reference year, when the amount was of 4000 transistors per IC, hence the value of parameter a is given as follows:
a = 4000.
Thus the equation is:
\(A(t) = 4000(2)^{\frac{t}{2}}\)
Giving the number of transistors per IC in t years after the reference year of 1972.
2016 was 44 years after 1972, hence the estimate for the amount of transistors by IC was of:
\(A(44) = 4000(2)^{\frac{44}{2}} = 16,777,216,000\)
2040 will be 68 years after 1972, hence the estimate for the amount of transistors by IC is of:
\(A(68) = 4000(2)^{\frac{68}{2}} = 6.87 \times 10^{13}\)

Round to the nearest tenth of a million. Does this function value overestimate or underestimate the US population in 2010 given in the table? By how much? According to the logarithmic regression model, when will the US population be 400 million?
Answers
The logarithmic regression equation that models the situation is given as follows:
y = 242.9037 + 23.7097ln(x).
The estimated population in 2010 is of:
313.9 million
Which overestimates the actual amount by 5.2 million.
The prediction for when the population will be of 400 million is of:
Year of 2,744.
How to obtain the logarithmic regression equation?The logarithmic regression equation is obtained inserting the points of the data-set into a logarithmic regression calculator.
From the table given by the image at the end of the answer, the points are given as follows:
(0, 248.8), (10, 281.4), (20, 308.7), (30, 331.4), (31, 331.9).
Inserting these points into a calculator, the equation is given as follows:
y = 242.9037 + 23.7097ln(x).
2010 is 20 years after 1990, hence the estimate is given as follows:
y = 242.9037 + 23.7097 x ln(20) = 313.9 million.
The overestimate of the actual value, from the table, is of:
313.9 - 308.7 = 5.2 million.
The prediction for when the population will be of 400 million is obtained as follows:
400 = 242.9037 + 23.7097 x ln(x)
ln(x) = (400 - 242.9037)/23.7097
ln(x) = 6.6258.
x = e^(6.6258)
x = 754.
Hence during the year of 2,744.
