So apparently the underlined answer is correct. Can somebody explain why? I will give brainliest if I get a good explanation.

The answer is "Failure of the reproductive structures to survive the frost". It is the most common factor limiting aspen's distribution along with the western edge of range in Canada.

Aspen trees are the one that are adapted to surviving in cold climates or cold weather but reproductive structures, like flowers and fruits are more sensitive to the frost. Cold temperatures at the western end of the shivering Canadian Cottonwood Range can cause frosts that damage and destroy that reproductive structures. This factor is most common factor that is restricting the distribution of aspens along the western edge of their range in Canada.

In addition, the harsh climate of "may" also limit the growth of popular seedlings, thus, aspen's range is limited by a lack of reproductive and growing success in the colder parts of its range.

the netballer's average for the whole season is 14.44 goals per game.by forming equation and solving it we are able to get answer.

what is  equation ?

An equation is a mathematical statement that asserts that two expressions are equal. It is typically written using an equal sign (=) between the two expressions. An equation can contain variables, which are symbols that represent unknown values.

In the given question,

To find the netballer's average for the whole season, we need to calculate the total number of goals she scored and the total number of matches she played.

Total number of goals scored in the season = (number of matches played before the final two matches) x (average number of goals per game) + (number of goals scored in the final two matches)

= 14 x 16.5 + 21 + 24

= 231

Total number of matches played in the season = 14 + 2 (final two matches)

= 16

Therefore, the netballer's average for the whole season is:

average number of goals per game = total number of goals scored / total number of matches played

= 231 / 16

= 14.44 (rounded to two decimal places)

Hence, the netballer's average for the whole season is 14.44 goals per game.

The equation for the relationship between x and y is y=5x and by the analysis of the graph, the constant of proportionality is 5.

By analyzing the graph given we can infer that  If four rooms are reserved, he must provide twenty towels.

So x is the number booked and y is the number of towels, Then x is directly proportional to y,

The given graph is linear in nature, as we increase x, there will be a significant increase in y, The constant of proportionality(k) tells us how much y will change when x changes.

The ratio connecting two given numbers in what is known as a proportional relationship is the constant of proportionality. The constant of proportionality may also be referred to as the constant ratio, constant rate, unit rate, constant of variation, or even the rate of change.

Answer:

To find the value of y from a given value of x, find the position of x on the x-axis, then trace vertically until you meet the line.  Once you meet the line, trace horizontally to the y-axis to find the corresponding value of y.

To find the value of x from a given value of y, find the position of y on the y-axis, then trace horizontally until you meet the line.  Once you meet the line, trace vertically to the x-axis to find the corresponding value of x.

From inspection of the graph,

when x = 1,  y = -1

when x = 0, y = 2

when x = 2, y = -4

Therefore,

\(\begin{array}{| c | c |}\cline{1-2} x & y\\\cline{1-2} 1 & -1 \\\cline{1-2} 0 & 2 \\\cline{1-2} 2 & -4 \\\cline{1-2}\end{array}\)

To find the equation of the line, find the slope:

\(\sf slope\:(m)=\dfrac{change\:in\:y}{change\:in\:x}=\dfrac{2-(-1)}{0-1}=-3\)

Then use one of the points and the found slope with the point-slope form of a linear equation: \(y-y_1=m(x-x_1)\)

\(\implies y-2=-3(x-0)\)

\(\implies y=-3x+2\)

So the equation of this line is: \(y=-3x+2\)

The correct answer is (a) yes; the equilateral triangle tessellates the plane.

A tessellation is a tiling of the plane using one or more geometric shapes without any gaps or overlaps. For a regular polygon to tessellate the plane, the sum of its interior angles must be a multiple of 360 degrees.

For an equilateral triangle, each angle measures 60 degrees, so the sum of the angles in a triangle is 180 degrees. Therefore, the sum of the interior angles in a tessellation of equilateral triangles must be a multiple of 180 degrees.

Since the measure of the interior angle of an equilateral triangle is 60 degrees, we can tile the plane with equilateral triangles meeting at each vertex. At each vertex, the sum of the interior angles of the three triangles is 180 degrees, so the tessellation meets the requirement that the sum of the interior angles is a multiple of 360 degrees.

Therefore, the answer is (a) yes; the equilateral triangle tessellates the plane.

The ratio of c:d:e is 1:3:2.

To find the ratio, you can multiply the first ratio by the second ratio: 1 * 2 = 2 and 3 * 3 = 9, so the ratio becomes 2:9:6, which can be simplified to 1:3:2.

A ratio is a comparison between two values. To calculate a ratio, divide the first value by the second value. For example, if you have three apples and seven bananas, the ratio of apples to bananas would be 3/7.

You can also simplify a ratio by dividing both values by their greatest common divisor. For example, if the ratio of apples to bananas is 6/14, you could simplify it to 3/7.

It's also possible to express a ratio as a fraction, decimal, or percentage. To convert a ratio to a fraction, simply divide the two values. To convert a ratio to a decimal, divide the numerator by the denominator. To convert a ratio to a percentage, multiply the ratio by 100.

The maximum profit is $5000, which can be achieved by planting 50 acres of corn and 0 acres of wheat.

This is a linear programming problem that can be solved using the simplex method. We can define two decision variables

x1: the number of acres of wheat to be planted

x2: the number of acres of corn to be planted

The objective is to maximize the profit, which can be expressed as

maximize 80x1 + 100x2

The constraints are:

4x1 + 16x2 <= 800 (limit on labor hours)

20x1 + 40x2 <= 2400 (limit on capital)

x1, x2 >= 0 (non-negativity constraint)

We can rewrite the constraints in the form of inequalities:

x2 <= 50 - 0.25x1

x2 <= 60 - 0.5x1

x1, x2 >= 0

The first two constraints are derived by dividing the labor and capital constraints by the respective coefficients of x2 and x1.

The feasible region is bounded by the x-axis, y-axis, and the two lines given by the above inequalities. It is a convex polygon with vertices at (0,0), (0,50), (20,30), and (40,0).

To find the maximum profit, we need to evaluate the objective function at each vertex of the feasible region and choose the one with the highest value. This can be done as follows

At (0,0), the profit is 0.

At (0,50), the profit is 5000.

At (20,30), the profit is 3400.

At (40,0), the profit is 3200.

Therefore, the maximum profit is $5000

Step-by-step explanation:

To perform a two-tailed hypothesis test with a sample size of 18 and a significance level of α = 0.10, the critical t-values are approximately ±2.110.

To find the critical values for a two-tailed hypothesis test with a sample size of 18 and a significance level of α = 0.10, you need to follow these steps:

1. Determine the degrees of freedom (df) for the t-distribution. In this case, df = n - 1 = 18 - 1 = 17.

2. Divide the significance level by 2 to account for the two tails. α/2 = 0.10/2 = 0.05.

3. Look up the critical t-value in the t-distribution table for a two-tailed test with a significance level of 0.05 and 17 degrees of freedom. The critical t-value is approximately ±2.110.

Therefore, the critical t-values for the two-tailed hypothesis test with a sample size of 18 and α = 0.10 are approximately ±2.110.

To determine the value of the asset based on its risk classification and the required rate of return, we can use the concept of present value.

a) Value of the Asset based on Risk Classification:

(1) Low-Risk: To calculate the value of the asset if it is classified as low-risk, we can use the required rate of return of 4% as the discount rate. The cash inflows for the next four years can be discounted using the present value formula:

PV = CF1 / (1 + r)^1 + CF2 / (1 + r)^2 + CF3 / (1 + r)^3 + CF4 / (1 + r)^4

where PV is the present value, CF is the cash flow, r is the discount rate, and the subscripts represent the time periods.

(2) Average-Risk: For average-risk assets, the required rate of return is 7%. Use the same formula as in the low-risk case, but with the discount rate of 7%.

(3) High-Risk: For high-risk assets, the required rate of return is 12%. Apply the present value formula with the discount rate of 12%.

b) Value of the Asset without Knowing the Risk:

If Laura cannot assess the risk of the asset, the most she should pay would be based on the highest required rate of return among the three risk classifications. In this case, she should use the discount rate of 12% to calculate the present value of the cash inflows.

c) Effect of Risk on Asset Value:

Increasing risk has a significant effect on the value of an asset. As the required rate of return increases with higher risk, the present value of the cash inflows decreases. This means that the higher the risk associated with an asset, the lower its value will be, assuming all else remains constant.

In light of the findings in part a, we can observe that the value of the asset decreases as the required rate of return increases for different risk classifications. This confirms the inverse relationship between risk and asset value.

The quadratic inequality defined on the graph is given as follows:

y ≥ 2/3(x + 3)² - 24.

The coordinates of the vertex of the quadratic function are given as follows:

(-3, -24).

Hence the quadratic function is given as follows:

y = a(x + 3)² - 24.

In which a is the leading coefficient.

When x = 3, y = 0, hence the leading coefficient a is obtained as follows:

0 = a(3 + 3)² - 24

36a = 24

a = 24/36

a = 2/3.

Hence:

y = 2/3(x + 3)² - 24.

Answer:

Two: \(\sqrt{d}\) and \(\left(-\sqrt{d}\right)\).

Step-by-step explanation:

The question is asking for the number of real numbers \(x\) whose square is equal to \(d\) (where \(d > 0\).)

Naturally, the square root of \(d\): \(\sqrt{d}\) would satisfy the requirement. \(\left(\sqrt{d}\right)^{2} = d\).

However, keep in mind that \((x)^2\) and \((-x)^{2}\) have the same value. Therefore, if \(x =\sqrt{d}\) would satisfy the equation, the opposite \(x = -\sqrt{d}\) would also do.

Since \(d > 0\), \(\sqrt{d}\) and \(\left(-\sqrt{d}\right)\) would both take real values.

Because \(d \ne 0\), the value of \(\sqrt{d}\) and \(\left(-\sqrt{d}\right)\) would be distinct.

Hence, \(\sqrt{d}\) and \(\left(-\sqrt{d}\right)\) would correspond to the two real solutions of this equation.
