The inverse of f(x) is f⁻¹(x) = ± √(-x+1). The inverse is not a function due to the presence of two possible values for y.

Given the function,

f(x)=-x²+1

To find the inverse of the function, interchange x and y. Then solve for y.

x = -y²+1y² = -x+1y = ± √(-x+1)

Now the inverse of f(x) is f⁻¹(x) = ± √(-x+1)

Now, to find the domain and range of the function and its inverse:

Domain of f(x) is all real numbers

Domain of f⁻¹(x) is x ≤ 1

Range of f(x) is (-∞, 1]

Range of f⁻¹(x) is all real numbers

Hence, the domain of the inverse is not a function because there are two values of y for each value of x, and the range of the original function is not the same as the domain of its inverse, thus the inverse is not a function.

Domain of f(x) is all real numbers

The absolute value of a number returns the positive value of the given number. A real life situation that describes the scenario is:

"the point which a boy stands if the boy is standing 2.5 meters away from the 7.5 meters point."

Given that:

\(x = 5\ or\ x = 10\)

An example of real life situation is as follows:

Calculate the point which a boy stands if the boy is standing 2.5 meters away from the 7.5 meters point.

Represent the point at which the boy stays with x. So, the situation is represented as:

\(|x - 7.5| = 2.5\)

Remove absolute brackets

\(x - 7.5 = 2.5\ or\ x - 7.5 = -2.5\)

Solve for x

\(x = 7.5+2.5\ or\ x = 7.5-2.5\)

\(x = 10\ or\ x = 5\)

Option A is the correct answer. Ellora wants to accumulate 150,000 in an RRSP by making annual contributions of 5,000 at the beginning of each year. If interest is 5.5% compounded quarterly, calculate how long she has to make contributions.

First, we have to find the interest rate per quarter, which will be
\(5.5% / 4\)= 1.375%.
The formula for the future value of an annuity is: 
\(FV = (C * [(1 + r)^n - 1] / r)\),

For Ellora, \(FV = $150,000, C = $5,000, and r = 1.375%.\)
Substituting these values into the formula gives:
\(150,000 = 5,000 * [(1 + 0.01375)^n - 1] / 0.01375\)
Simplifying this equation gives:
\(30 = [(1.01375)^n - 1]\)

We can solve this using logarithms:
\(ln 30 = ln [(1.01375)^n - 1]\)
\(ln 30 = n * ln 1.01375 - ln 1.01375e^(ln 30) / e^(-ln 1.01375) = n18.202125 = n\)

Therefore, it will take Ellora 18.202125 years to accumulate 150,000 in her RRSP through \($5,000\)annual contributions made at the beginning of each year with interest of \(5.5%\) compounded quarterly.

If the p-value is less than α (0.05), we reject the null hypothesis in favor of the alternative hypothesis.

To begin, let's calculate the mean age for the sample data provided. We have a sample size of 47 recently wed British men, and we need to find the sample mean and sample standard deviation.

To find the sample mean, we sum up all the ages and divide it by the sample size (47):

Sample Mean = (30 + 28 + 40 + ... + 33 + 31 + 25) / 47

Now that we have the necessary statistics, we can proceed with hypothesis testing. We will compare the mean age of the sample data to the mean age in 2013 (which was reported as 32.0) and test whether the difference is statistically significant.

Null Hypothesis (H0): The mean age of British men at the time of marriage is not significantly different from the mean age in 2013.

Alternative Hypothesis (Ha): The mean age of British men at the time of marriage has increased compared to the mean age in 2013.

To test this hypothesis, we will calculate the t-value and the p-value.

The t-value represents the difference between the sample mean and the hypothesized population mean (mean age in 2013) relative to the variability in the sample.

t-value = (Sample Mean - Population Mean) / (Sample Standard Deviation / √n)

In this case, the Population Mean is 32.0 (mean age in 2013), and n is the sample size (47). Plug in the values to calculate the t-value.

To calculate the p-value, we need to consult a t-distribution table or use statistical software. The p-value is the probability of observing a t-value as extreme as the one calculated in Step, given the degrees of freedom (df) associated with the t-distribution.

Finally, we compare the p-value to the significance level (α) to make a conclusion. If the p-value is less than α (0.05), we reject the null hypothesis in favor of the alternative hypothesis. If the p-value is greater than or equal to α, we fail to reject the null hypothesis.

In the given problem, the sum of \(\frac{4}{6}\) and \(\frac{4}{6}\) is \(\frac{4}{3}\).

The sum is the result of adding two or more numbers or terms. In other words, it is the process of bringing two or more numbers together to produce a new result or total. The symbol for the sum is "+".

The sum can be performed on any kind of number, including whole numbers, integers, rational numbers, real numbers, and complex numbers. The rules for addition are the same for all types of numbers.

To find the sum of \(\frac{4}{6}\) and \(\frac{4}{6}\),

\(\frac{4}{6}\) +  \(\frac{4}{6}\) = 2 \(\times \ \frac{4}{6}\)

        = \(\frac{4}{3}\).

The equation in slope-intercept form for Bill's finances is \(\(y = -75x + 975\).\) This equation represents the amount of money remaining in Bill's account for extra expenses at the end of each month.

Let's assume the number of months passed since January as "m" and the amount of money remaining in Bill's account for extra expenses at the end of each month as "y".

We are given the following information: In January (x = 1), Bill has not started spending yet, so he has all his expenses available. Therefore, at the beginning of January, he has $900 (y = 900) remaining for extra expenses.

Each month, Bill spends $75 on extra expenses. So, as the number of months increases, the remaining amount decreases.

Now, let's set up the equation in point-slope form using the point (1, 900) and the slope (-75): \(\[y - y_1 = m(x - x_1)\]\)

where:

\(\(y_1 = 900\) (remaining amount in January)\\\(m = -75\) (slope, indicating $75 reduction each month)\\\(x_1 = 1\) (January)\\\)

Now plug in the values: \(\[y - 900 = -75(x - 1)\]\)

Next, let's simplify the equation and convert it to slope-intercept form (y = mx + b) where "b" represents the y-intercept (the remaining amount when x = 0, i.e., the start of the year).

\(\[y - 900 = -75x + 75\]\)

To isolate "y," add 900 to both sides: \(\[y = -75x + 975\]\)

So, the equation in slope-intercept form for Bill's finances is \(\(y = -75x + 975\).\) This equation represents the amount of money remaining in Bill's account for extra expenses at the end of each month.

Step-by-step explanation:

Using binary search to find the key 60 in the given list, the elements compared in order are: 38, 76, 60.

1. We start by comparing the key (60) to the middle element of the list, which is 38. Since 60 is greater than 38, we know that the key must be in the second half of the list.
2. Next, we compare the key to the middle element of the second half of the list, which is 76. Since 60 is less than 76, we know that the key must be in the first half of the second half of the list.
3. We then compare the key to the middle element of the first half of the second half of the list, which is 50. Since 60 is greater than 50, we know that the key must be in the second half of the first half of the second half of the list.
4. Next, we compare the key to the middle element of the second half of the first half of the second half of the list, which is 72. Since 60 is less than 72, we know that the key must be in the first half of the second half of the first half of the second half of the list.
5. Finally, we compare the key to the middle element of the first half of the second half of the first half of the second half of the list, which is 60. Since 60 is equal to 60, we have found the position of the key in the list.
