Half life of the radioactive substance is 3.6  days

The half life of the element is calculated from the formula

N(t) = N'(1/2)^(t/t')

N(t) = quantity of the substance remaining

N' = initial quantity of the substance

t = time elapsed

t' = half life of the substance

0.4 = 4.8 (0.5)^13/t'

0.4 / 4.8 =  (0.5)^13/t'

take natural logarithm of both sides

㏑(0.4/4.8) = 13/t' ㏑(0.5)

divide through by natural log of 0.5

-2.4849 / ㏑(0.5) = 13/t'

13/t' = 3.58496

t' = 13 / 3.58496

t' = 3.626 days

This measure of central tendency can be considered the most precise in option c. mean

The mean is a measure of central tendency that calculates the average of a set of values. It is often considered the most precise measure because it takes into account all the values in the dataset and provides a balanced representation.

The mean is calculated by summing all the values and dividing by the total number of values. Unlike the mode, which only identifies the most frequently occurring value, and the median, which represents the middle value, the mean incorporates all the values and provides a comprehensive summary of the dataset.

However, it is important to note that the mean can be sensitive to extreme values or outliers in the data.

The grower should plant 59 trees per acre to maximize her harvest, and the maximum harvest she can achieve is approximately 3540 bushels.

To determine the number of trees the plum grower should plant per acre to maximize her harvest, we can set up an equation and use calculus to find the optimal solution. Let's denote the number of additional trees planted as x.

The yield of each tree can be represented by the equation:

Yield = 126 - 2x

The total yield per acre is then given by:

Total Yield = (26 + x) * (126 - 2x)

To maximize the harvest, we need to find the value of x that maximizes the total yield. We can achieve this by finding the maximum point of the quadratic equation representing the total yield.

Differentiating the equation with respect to x and setting it equal to zero, we can find the critical point:

d(Total Yield)/dx = -4x + 252 - 2(26 + x) = 0

Simplifying the equation, we get:

-4x + 252 - 52 - 2x = 0

-6x + 200 = 0

x = 200/6

x ≈ 33.33

Since we cannot have a fraction of a tree, the grower should plant 33 additional trees per acre to maximize her harvest. This gives a total of 26 + 33 = 59 trees per acre.

To find the maximum harvest, we substitute the value of x into the equation for the total yield:

Total Yield = (26 + 33) * (126 - 2 * 33)

Total Yield ≈ 59 * 60

Total Yield ≈ 3540 bushels

Therefore, the grower should plant 59 trees per acre to maximize her harvest, and the maximum harvest she can achieve is approximately 3540 bushels.

The derivative of the given function is:

f'(x) + g'(x) = (-60 / (x^5)) + (1/4)x^-3

To use the power rule, we differentiate each term separately and then add the results.

For the first term, we have:

f(x) = (15/ (x^4))

Using the power rule, we bring down the exponent, subtract one from it, and multiply by the derivative of the inside function, which is 1 in this case. Therefore, we get:

f'(x) = (-60 / (x^5))

For the second term, we have:

g(x) = -(1/8)x^-2

Using the power rule again, we bring down the exponent -2, subtract one from it to get -3, and then multiply by the derivative of the inside function, which is also 1. Therefore, we get:

g'(x) = 2(1/8)x^-3

Simplifying this expression, we get:

g'(x) = (1/4)x^-3

Now, we can add the two derivatives:

f'(x) + g'(x) = (-60 / (x^5)) + (1/4)x^-3

Therefore, the derivative of the given function is:

f'(x) + g'(x) = (-60 / (x^5)) + (1/4)x^-3

To find the average height of the paraboloid \(z = x^2 + y^2\) over the square, we need to calculate the average value of z over the given square region.

Let's denote the square region as R, with sides of length L. Since the square is centered at the origin (0, 0), its vertices can be represented as \(\left(\frac{L}{2}, \frac{L}{2}\right), \left(-\frac{L}{2}, \frac{L}{2}\right), \left(\frac{L}{2}, -\frac{L}{2}\right), \text{ and } \left(-\frac{L}{2}, -\frac{L}{2}\right)\).

The average value of a function f(x, y) over a region R is given by the double integral:

\(\text{Avg}(f) = \frac{1}{\text{Area}(R)} \iint_R f(x, y) \, dA\),

where dA represents the differential area element and Area(R) is the area of the region R.

In this case, we want to find the average height of the paraboloid \(z = x^2 + y^2\), so our function is \(f(x, y) = x^2 + y^2\).

The differential area element dA in Cartesian coordinates is given by dA = dx dy.

The region R is a square with sides of length L, so its area is given by \(Area(R) = L^2\).

Substituting the function, differential area, and region area into the average formula, we have:

\(\text{Avg}(f) = \frac{1}{L^2} \iint_R (x^2 + y^2) \, dx \, dy\)

To evaluate the double integral, we integrate with respect to x from \(-\frac{L}{2} \text{ to } \frac{L}{2}\), and with respect to y from \(-\frac{L}{2} \text{ to } \frac{L}{2}\).

\(\text{Avg}(f) = \frac{1}{L^2} \int_{-\frac{L}{2}}^{\frac{L}{2}} \int_{-\frac{L}{2}}^{\frac{L}{2}} (x^2 + y^2) \, dx \, dy\)

Integrating with respect to x, we get:

\(\text{Avg}(f) = \frac{1}{L^2} \int_{-\frac{L}{2}}^{\frac{L}{2}} \left(\frac{x^3}{3} + xy^2\right) \, dx \, dy\)

Simplifying, we have:

\(\text{Avg}(f) = \frac{1}{L^2} \int_{-\frac{L}{2}}^{\frac{L}{2}} \left(\frac{L^3}{12} + \frac{y^2L}{4}\right) \, dy\)

Integrating with respect to y, we get:

\(\text{Avg}(f) = \frac{1}{L^2} \left[\left(\frac{L^3}{12}\right)y + \left(\frac{y^3L}{4}\right)\right]_{-\frac{L}{2}}^{\frac{L}{2}}\)

Evaluating the integral limits, we have:

\(\text{Avg}(f) = \frac{1}{L^2} \left[\left(\frac{L^3}{12}\right)\left(\frac{L}{2}\right) + \left(\left(\frac{L}{2}\right)^3\frac{L}{4}\right)\right]\)

Simplifying further:

\(\text{Avg}(f) = \frac{1}{L^2} \left[ \frac{L^4}{24} + \frac{L^4}{32} \right]\\\\= \frac{1}{L^2} \left[ \frac{8L^4 + 6L^4}{96} \right]\\\\= \frac{1}{L^2} \left( \frac{14L^4}{96} \right)\\\\= \frac{14L^2}{96}\)

Therefore, the average height of the paraboloid \(z = x^2 + y^2\) over the given square region is \(\text{Avg}(f) = \frac{14L^2}{96}\).

To evaluate the line integral ∮C F · dr using Green's theorem, we need to confirm the orientation of the curve C and apply the appropriate sign. Therefore, ∮C F · dr = -8 - 8π.

Given the vector field F(x, y) = ⟨y - cos(y), x sin(y)⟩ and the curve equation \((x - 4)^2 + (y + 9)^2 = 16\), let's proceed with the evaluation.

1. Orientation of Curve C:

To determine the orientation, we can parametrize the curve equation. Let's use the parameterization:

x = 4 + 4cos(t)

y = -9 + 4sin(t)

By analyzing the parameterization, we find that the curve C is oriented counterclockwise as t varies from 0 to 2π.

2. Green's Theorem:

Green's theorem states that ∮C F · dr = ∬D (∂Q/∂x - ∂P/∂y) dA, where D is the region enclosed by the curve C, F = (P, Q) is the vector field, and dr = (dx, dy) is the differential displacement vector.

3. Apply Green's Theorem:

Let's compute the double integral of (∂Q/∂x - ∂P/∂y) over the region D.

∬D (∂Q/∂x - ∂P/∂y) dA = ∬D ((∂/∂x)(x sin(y)) - (∂/∂y)(y - cos(y))) dA

4. Evaluate the Double Integral:

Integrate (∂/∂x)(x sin(y)) and (∂/∂y)(y - cos(y)) with respect to x and y over the region D.

∬D (∂Q/∂x - ∂P/∂y) dA = ∫(0 to 2π) ∫(0 to 4) (sin(y) - 1) dx dy

Evaluate the inner integral:

= ∫(0 to 2π) [x sin(y) - x] |(0 to 4) dy

= ∫(0 to 2π) (4sin(y) - 4) dy

Evaluate the outer integral:

= [-4cos(y) - 4y] |(0 to 2π)

= [-4cos(2π) - 4(2π)] - [-4cos(0) - 4(0)]

Simplifying, we get:

= [-4 - 8π] - [-4]

= -8 - 8π

What is equilateral triangle?

An equilateral triangle in geometry is a triangle with equal-length sides on all three sides. In the well-known Euclidean space, an equilateral triangle also is equiangular, meaning that each of its three internal angles is 60 degrees and congruent with the others. It's also referred to it as a regular triangle because it is a regular polygon.

To find the intersection point between the curve y = tan(x) and the line y = 7x, we can use Newton's method. Newton's method is an iterative numerical method used to approximate the root of a function.

We need to find the x-value where the curves intersect, so we can set up the equation tan(x) - 7x = 0. We want to find a solution between x = 0 and some unknown value denoted as X.

Using Newton's method, we start with an initial guess x_0 for the solution and iterate using the formula:

x_(n+1) = x_n - f(x_n) / f'(x_n),

where f(x) = tan(x) - 7x and f'(x) is the derivative of f(x).

We continue this iteration until we reach a desired level of accuracy or convergence. The resulting value of x will be the approximate intersection point between the two curves.

Please note that without specific values or range for X or an initial guess x_0, it is not possible to provide a specific numerical answer. However, you can apply Newton's method using an initial guess and the given function to find the approximate intersection point.
