The simplest form of  the exponent number of 3^(5/2) is √243.

What is exponential form of a number?

To express numbers that are either too large or too tiny, use exponential notation, which raises the number to the power of the appropriate exponent. The exponent's power might either take the positive or negative form.

For instance, we may express the exponential form of 5 × 5 × 5 × 5 as 5⁴, where 5 is the base and 4 is the power. The power here indicates how many times we are multiplying the base by itself.

Given number is 3^(5/2)

The base of the given number is 3 and exponent 5/2.

Apply the formula a^(m/2) = √a^m in the given number:

3^(5/2) = √3⁵

Putting 3⁵ = 243

3^(5/2) = √243.

Part 1: The point of maxima is 21.212

Part 2: x = 21.212 is approximately equal to the year 2022

Part 3: The percentage at that time is 16.37%

Part 4: The rate of change of the percentage at that time is 0.294

Part 1:

p(x) = −0.00022x^3 + 0.014x^2 − 0.0033x + 12.236

where x is the number of years since 2000, data from 0<=x<=50

Differentiating the function with respect to x and equating it to 0

p'(x) = -0.00066x^2 + 0.028x - 0.0033

We will find the critical points of p'(x)

p''(x) = dp'(x)/dx  = -0.00132x + 0.028

Critical points of p'(x) lies at x where p''(x) = 0

Thus, -0.00132x + 0.028 = 0

x = 0.028/0.00132 = 21.212

Now, p'''(x) = -0.00132<0

x = 21.212 is a point of maxima of p'(x)

Therefore, the maximum possible values of x could lie at x = 21.212 as well as the extreme points of the domain p'(x), i.e. at x = 0 and 50

p'(0) = -0.00066(0)^2 + 0.028(0) - 0.0033 = -0.0033

p'(21.212) = -0.00066(21.212)^2 + 0.028(21.212) - 0.0033 = 0.2936

p'(50) = -0.00066(50)^2 + 0.028(50) - 0.0033 = -0.2533

Hence p'(x) attains maxima at x = 21.212

Therefore, p(x) increases most rapidly at x = 21.212

Part 2:

From the given condition in the question, x = 0 corresponds to the year 2000

Thus x = 21.212 is approximately equal to year 2022

Part 3:

The percentage at that time:

p(x) = −0.00022x^3 + 0.014x^2 − 0.0033x + 12.236

p(21.212) = -0.00022(21.212)^3 + 0.014(21.212)^2 - 0.0033(21.212) + 12.236

= 16.365

= 16.37%

Part 4:

Rate of change of the percentage at that time

p(x) = −0.00022x^3 + 0.014x^2 − 0.0033x + 12.236

p'(21.212) = -0.00066(21.212)^3 + 0.028(21.212) - 0.0033

= 0.2936

Division C’s highest acceptable transfer price if it were to buy 4,000 units from Division B should be $58.

The transfer price is the price that Division B should charge Division C for the internal supply of goods or services.

Ordinarily, the transfer price equals the outlay cost (production cost) plus the opportunity cost (profit from selling outside).

The highest acceptable transfer price that Division C should reflect the market price at which Division C could acquire the parts from outside.

Division B:

Outside market selling price per unit = $60

Variable cost per unit = $44

Fixed cost per unit = $8

Capacity in units = 20,000 units

Units sold outside by Division B = 15,000 units

Excess units = 5,000 units (20,000 - 15,000)

Units required by Division C = 4,000 units

Outside supplier's price per unit = $58

Thus, the highest acceptable transfer price should be $58 and not $60.

C. The Roth IRA reduces the tax burden because its taxes are calculated in a lower bracket.

In a traditional IRA, contributions may be tax-deductible in the year they are made, but withdrawals in retirement are taxed as ordinary income. This means that the $1000.00 investment in a traditional IRA would be taxed at the investor's ordinary income tax rate when it is withdrawn in retirement. If the investor's ordinary income tax rate is 12%, then the tax burden on the $1000.00 investment in a traditional IRA would be $120.00.

In a Roth IRA, contributions are not tax-deductible, but withdrawals in retirement are tax-free. This means that the $1000.00 investment in a Roth IRA would be taxed at the investor's ordinary income tax rate when it is made, but it would not be taxed when it is withdrawn in retirement. If the investor's ordinary income tax rate is 10%, then the tax burden on the $1000.00 investment in a Roth IRA would be $100.00.

Overall, the tax burden on the $1000.00 investment in a Roth IRA is lower than the tax burden on the same investment in a traditional IRA because the taxes on the Roth IRA are calculated in a lower bracket (10% vs 12%).

The equation of the line perpendicular to the line y = 3x+7 is 3y = -x-17

The slope or gradient of a line is a number that describes both the direction and the steepness of the line.

Given that, a line is perpendicular to line y = 3x+7 and passing through points (-2,-5)

The slope of perpendicular lines is negative reciprocal of each other.

Therefore, the slope of the asked line is -1/3

Finding c,

-5 = -1/3x(-2)+c

c = -17/3

Therefore, the equation of the line is y = -1/3x-17/3 or 3y = -x-17

A rectangle's greatest area is 32 square units.

Given:

A parabola's equation is y = 12 - x2, which is an even function

As a result, its rectangular shape is also even at the origin.

We are aware that the area of a rectangle is equal to its length times its width.

Here,

width = y, length = 2x

A = 2x, where (12 -  [tex]x^{2}[/tex])

⇒ A = 24x - 2[tex]x^{3}[/tex]

Consider the A derivative with regard to x.

⇒ A' = 24 - 6 [tex]x^{2}[/tex]

When A' = 0, the area is the largest.

⇒ 24 - 6x2 = 0

⇒ [tex]x^{2}[/tex] = 4

⇒ x = 2

Replace x with its value in y = 12 -  [tex]x^{2}[/tex].

⇒ y = 12 - 4

For this sample, a confidence interval based on the t distribution with 95% degrees of freedom would be appropriate.

In most research, the 95% confidence interval (95 CI) is reported. If the confidence interval (e.g., 95%CI 0.9-1.1) crosses 1, it is assumed that there is no difference between the research arms.

In the two-tailed t table, determine the critical value of t. Add s/n to the crucial value of t. Calculate the top limit of the confidence interval by adding this value to the mean, and the lower limit by deducting this value from the mean.

With a significance level of 0.05 (i.e., a confidence level of 95%), the confidence interval is calculated using the T function.

The critical value for a 99% confidence interval for this sample, according to Table 1, is 2.576.

State the null and alternate hypotheses in step one.

H0: (p1-p2) = 0

Step 2: Calculate the test statistic

We can calculate the test statistic using the formula:

z = (p1-p2)/√(p(1−p)(1/n1+1/n2))

where,

p = (successes in sample 1 + successes in sample 2)/(n1+n2)

= 61/160

= 0.30

n1 = sample size of population 1

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract x from both sides of the equation:
