Explanation:

Amit's mistake : The point (2, –2) doesn’t lie on the circle because the calculated distance should be the same as the radius.

The point (2,-2) is on the circle, and Amit's claim is wrong

The given parameters are:

Center = (-1,2)

Diameter = 10 units

Point = (2,-2)

Start by calculating the radius, r

r = diameter/2

r = 10/2

r = 5

Next, calculate the distance from the point to the center using:

\(r = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}\)

This gives

\(r = \sqrt{(2 + 1)^2 + (-2-2)^2}\)

Evaluate

r = 5

The distance from the center to the point equals the radius of the circle

Hence, the point is on the circle, and Amit's claim is wrong

The clerk actually spent approximately 15.71% of his time on messenger work during the week.

The clerk spent 1/5 of his time sorting mail, which is equal to 7 hours (1/5 x 35 hours). He also spent 1/2 of his time filing letters, which is equal to 17.5 hours (1/2 x 35 hours). Additionally, he spent 1/7 of his time in reception work, which is equal to 5 hours (1/7 x 35 hours).

To find the amount of time he spent on messenger work, we can subtract the total time spent on sorting mail, filing letters, and reception work from the total 35-hour workweek:

35 hours - 7 hours - 17.5 hours - 5 hours = 5.5 hours

Thus, the clerk spent 5.5 hours on messenger work during the week. To find the percentage of time he spent on messenger work, we can divide this amount by the total number of hours worked and multiply by 100:

(5.5 hours / 35 hours) x 100% ≈ 15.71%

Ratio is a numerical comparison of two or more values. It is a mathematical expression that shows the relationship between two or more quantities. Ratios are used to compare the relative size of two or more values, to measure changes over time, to quantify proportions, and to evaluate relationships between sets of data. In some cases, ratios can also be used to compare absolute values. Ratios are often expressed in the form of fractions, although they can also be expressed as decimals or percentages. Ratios can be used to compare two or more items or groups of data, and can be expressed as a single number or in a range of numbers.

This means that as x increases, y will increase at the same rate. Similarly, as x decreases, y will decrease at the same rate.

The required  cost of each shirt is $21.28.

A mathematical statement known as an equation is made up of two expressions joined together by the equal symbol. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the quantity x is 7.

The total cost of 3 identical shirts, including shipping, is $71.83. So we can write the equation as:

3s + 7.99 = 71.83

To solve for the cost of each shirt, we need to isolate the variable "s" on one side of the equation. We can start by subtracting 7.99 from both sides:

3s = 63.84

Then, we can divide both sides by 3:

s = 21.28

Therefore, the cost of each shirt is $21.28.

A plasmid used in both yeast and bacteria requires two different selection markers because the same selection may not work for both hosts and bacteria and yeast recognize different promoters.

When using a plasmid in both yeast and bacteria, it is important to have two different selection markers for several reasons. First, the same selection, such as the presence of an antibiotic, may not be effective in both hosts. Different organisms have varying sensitivities to antibiotics, so a marker that works in bacteria may not work in yeast or vice versa. Therefore, two different selection markers are needed to ensure successful selection in both hosts.

Additionally, bacteria and yeast recognize different promoters, which are DNA sequences that control the initiation of gene expression. Promoters are specific to each organism and play a crucial role in regulating gene expression. By incorporating two different selection markers into the plasmid, each marker can be driven by a promoter recognized specifically by the corresponding host. This ensures that the selection marker is effectively expressed in the appropriate host organism, enabling accurate selection and maintenance of the plasmid.

In summary, using two different selection markers in a plasmid intended for both yeast and bacteria is necessary because the same selection may not be effective in both hosts, and different promoters are recognized by bacteria and yeast. This approach allows for successful selection and maintenance of the plasmid in both organisms.

Remember that a dilation stretches or compresses an object based on a given scale factor, therefore, the correct option is C

The perimeter of the rectangle, when the area is maximized, is approximately 24.63 units. Therefore, correct option is a.

To maximize the area of the rectangle inscribed in the parabola \(y^2 = 16x\), we need to find the dimensions of the rectangle. Since the side of the rectangle is along the latus rectum of the parabola, we know that the length of the rectangle is equal to the latus rectum.

The latus rectum of the parabola \(y^2 = 16x\) is given by the formula 4a, where "a" is the distance from the focus to the vertex of the parabola. In this case, the focus is located at (4a, 0).

To find "a," we can equate the equation of the parabola to the general equation of a parabola in vertex form: \(y^2 = 4a(x - h)\), where (h, k) is the vertex of the parabola.

Comparing the two equations, we get:

4a = 16

a = 4

Therefore, the latus rectum of the parabola is 4a = 4 * 4 = 16 units.

Since the length of the rectangle is equal to the latus rectum, we have length = 16 units.

Now, to find the width of the rectangle, we need to determine the corresponding y-coordinate on the parabola for the given x-coordinate of the latus rectum. The x-coordinate of the latus rectum is half the length, which is 16/2 = 8 units.

Substituting x = 8 into the equation of the parabola, we get:

\(y^2 = 16(8)\\y^2 = 128\\y = \sqrt{128} = 11.31\)

Therefore, the width of the rectangle is approximately 11.31 units.

The perimeter of the rectangle is given by the formula:

Perimeter = 2(length + width)

Plugging in the values, we have:

Perimeter = 2(16 + 11.31)

Perimeter ≈ 2(27.31)

Perimeter ≈ 54.62

Rounding the perimeter to two decimal places, we get approximately 54.62 units, which is equivalent to 24.63 units.

So the maximum number of edges in an undirected graph with 100 vertices is 4950.

In an undirected graph, each edge connects two vertices, and as such, it is counted twice, once for each vertex it connects. Therefore, the total number of edges in the graph is the sum of the degrees of all vertices, divided by 2.

In a complete graph with n vertices, every vertex is connected to every other vertex, except itself, and so the degree of each vertex is n-1 (it is connected to n-1 other vertices). Therefore, the total number of edges in the graph is:

n * (n-1) / 2

Substituting n = 100, we get:

To model this situation, we can use two equations. Let the width of the rectangular garden be w feet and the length be l feet.

Then:We know that the perimeter of the garden is 90 feet because the amount of fencing used was 90 feet.Perimeter = sum of all sides2(l + w) = 90Divide both sides by 22(l + w)/2 = 45l + w = 45Now,

we also know that the length of the fence, 1, was 5 feet less than 3 times the width,

w.l = 3w - 5Substitute this equation for l in the first equation:3w - 5 + w = 45Simplify:4w - 5 = 45

Add 5 to both sides :4w = 50Divide both sides by 4:w = 12.5

Now that we know the width of the garden is 12.5 feet, we can use the equation for l to find the length:l = 3w - 5l = 3(12.5) - 5l = 30.5

It will take 56.2 years for Strontium-90 to decay to 25% of its initial quantity, when it has a half-life of 28.1 years.

The half life of an element is the time period in which it decomposes to half of itself.

The formula used is:

\(N(t) = N_0 (\frac{1}{2} )^{\frac{t}{t_{1/2} }}\),

where, N(t) is the final quantity of the element after time t, with the initial quantity was N₀, and \(t_{1/2}\) is the half life of that element.

In the question, we are given that Strontium-90 has a half-life of 28.1 years.

Thus, \(t_{1/2}\) = 28.1 years.

We are asked the time (t), it will take for a sample of Strontium-90 to decay to 25% of its initial quantity.

We assume the initial quantity to be N₀.

The final quantity N(t) is 25% of the initial quantity.

Thus, N(t) = 25% of N₀ = 25/100 * N₀ = N₀/4.

Substituting all the values in the formula, we get:

\(N(t) = N_0 (\frac{1}{2} )^{\frac{t}{t_{1/2} }}\\\Rightarrow N_0/4 = N_0(\frac{1}{2} )^{\frac{t}{28.1} }}\\\Rightarrow \frac{N_0/4}{N_0} = (\frac{1}{2} )^{\frac{t}{28.1} }}\\\Rightarrow \frac{1}{4} = (\frac{1}{2} )^{\frac{t}{28.1} }}\\\Rightarrow (\frac {1}{2})^2 = (\frac{1}{2} )^{\frac{t}{28.1} }}\\\Rightarrow \frac {t}{28.1} = 2\\\Rightarrow t = 28.1*2 = 56.2\)

Thus, it will take 56.2 years for Strontium-90 to decay to 25% of its initial quantity, when it has a half-life of 28.1 years.
