A kite is a quadrilateral which has two equal adjacent sides. Therefore measuring the lengths accurately would make the pieces of wood perpendicular. Since the diagonals of a kite are at right angle to each other.

Quadrilaterals are shapes which has four straight sides. Examples are; square, trapezium, kite, rectangle etc.

A kite is a shape which has adjacent sides to have equal lengths. It has two diagonals, and one line of symmetry.

The lengths of the sides of the fabric being exact imply that the pieces of wood would be perpendicular as suggested by Priya when fixed appropriately to the piece of fabric. This is because the diagonals of a kite are always perpendicular. Thus measuring the angles as suggested by Han is not necessary.

Visit: https://brainly.com/question/21979359

The 2 pieces of wood intersect at right angles if the length of sides of the fabric are measured correctly.

Since Priya said to Han that  "If we were careful about the lengths of the sides of the fabric, we don't need to measure the angle. It has to be a right angle."

Priya used the properties of a kite.

Since from the properties of a kite, two pairs of sides are equal. Also, since thes two pairs of sides are equal, the diagonals from the vertices of the kite intersect at right-angles.

So, as Priya said to Han, the angle made by the 2 pieces of wood have to be right angles if the sides are measured correctly, since the diagonals intersect at right angles.

So, the 2 pieces of wood intersect at right angles if the length of sides of the fabric are measured correctly.

bec we will do 720-3% which is going to give us the number exactly simple right ?

The implicit equation for the plane through (3,-2,2) normal to the vector ⟨4,1,-5⟩ is: 4(x - 3) + 1(y + 2) - 5(z - 2) = 0.

To find the implicit equation for the plane, we need the normal vector and a point on the plane. The given normal vector is ⟨4,1,-5⟩, which represents the coefficients of x, y, and z respectively. A point on the plane is (3,-2,2). Using the point-normal form of the equation, we substitute the values into the equation: 4(x - 3) + 1(y + 2) - 5(z - 2) = 0. Simplifying the equation gives us the implicit equation for the plane through the given point and normal vector.

Applying ratios, the length of segment EG is: 6.

Since the ratio of DE:EF:FG is 4:2:1, we know that DE =4x, EF = 2x, and FG = x, where x is some value. We also know that DG = DE+EF+FG, so we can set up the equation:

14 = 4x + 2x + x

Simplifying, we get:

14 = 7x

Dividing both sides by 7, we find that x = 2.

So, DE = 4x = 4(2) = 8, EF = 2x = 2(2) = 4, and FG = x = 2.

EG = EF + FG = 4 + 2 = 6.

Answer:

[ 0, 2 ] is the interval for the graphed function that contains the local maximum. Hence, the answer is [ 0, 2 ] is the answer.

Step-by-step explanation:

Answer:

  \(m(x)=\begin{cases}-\dfrac{1}{3}(x+4)^2+3&\text{ for }x \le-1\\4\left(\dfrac{1}{2}\right)^x&\text{ for }-1 < x < 3\\-x+5&\text{ for }3\le x\end{cases}\)

Step-by-step explanation:

The domain is the set of x-values for which the function is applicable. The pieces of a piecewise-defined function are each defined on their own domain. Here, there are three different functions, each defined on a different domain.

From left to right, the function's domain can be divided into the sections ...

This section of the graph looks like a parabola that opens downward. Its vertex is (-4, 3), and it seems to have a scale factor less than 1.

For some scale factor 'a', the function in vertex form is ...

  y = a(x -h)² +k . . . . . . quadratic with vertex (h, k)

  y = a(x +4)² +3

We know the point (x, y) = (-1, 0) is on the curve, so we can use these values to find 'a':

  0 = a(-1 +4)² +3 = 9a +3

  a = -3/9 = -1/3

So, the left-section function is ...

  m(x) = -1/3(x +4)² +3

__

The middle section of the graph has increasing slope, so might be a parabola or an exponential function. We note the average rate of change goes from -4 in the interval (-1, 0) to -2 in the interval (0, 1) to -1 in the interval (1, 2). The slope changing by a constant factor (1/2) in each unit interval is characteristic of an exponential function. That factor is the base of the exponent.

The actual values on the curve also decrease by a factor of 1/2 in each unit interval, which tells us the function has not been translated vertically. The y-intercept value of 4 at x=0 tells us the multiplier of the function:

  m(x) = 4(1/2)^x

__

The funciton in this domain is a straight line. It has a "rise" of -1 unit for each "run" of 1 unit, so its slope is -1. If we extend the line left to the y-axis, we see that it has a y-intercept of 5. Its equation is ...

  m(x) = -x +5

__

Putting the pieces together into one function description, we have ...

  \(m(x)=\begin{cases}-\dfrac{1}{3}(x+4)^2+3&\text{ for }x \le-1\\4\left(\dfrac{1}{2}\right)^x&\text{ for }-1 < x < 3\\-x+5&\text{ for }3\le x\end{cases}\)

_____

Additional comment

If the function in the middle section were quadratic, its average rate of change on adjacent equal intervals would form an arithmetic sequence. Because the sequence is geometric, we know it is an exponential function.

is finding the square root

The inverse operation of squaring a number is finding the square root of that number. The square root of a number "x" is the value that, when squared, gives the original number.

When a number is squared, it is multiplied by itself. For example, squaring the number 4 gives 4^2 = 16.

The inverse operation undoes the effect of squaring and returns you to the original number. In this case, finding the square root of a number is the inverse operation of squaring.

The square root of a number "x" is a value that, when squared, gives the original number. It is denoted by the symbol √x.

For example, if you have the number 25 and you want to find its square root, you calculate:

√25 = 5

5 is the square root of 25 because when you square 5 (5^2), you get 25.

The inverse operation of squaring a number is finding the square root of that number. The square root of a number "x" is the value that, when squared, gives the original number. The concept of square root and squaring are inverse operations that are used in various mathematical calculations and problem-solving.

The probabilities are as follows:

(a) Probability for 1 woman's weight between 108 lb and 175 lb: P(108 lb ≤ X ≤ 175 lb) = P(Z1 ≤ Z ≤ Z2)

(b) Probability for 4 women's mean weight between 108 lb and 175 lb: P(108 lb ≤ X_bar ≤ 175 lb) = P(Z1' ≤ Z ≤ Z2')

(c) Probability for 89 women's mean weight between 108 lb and 175 lb: P(108 lb ≤ X_bar ≤ 175 lb) = P(Z1'' ≤ Z ≤ Z2'')


Let's analyze each section separately:

(a) Probability for 1 woman's weight between 108 lb and 175 lb:

To find the probability that a randomly selected woman's weight falls within the range of 108 lb to 175 lb, we need to standardize the values using the Z-score formula. The Z-score (Z) is calculated as (X - μ) / σ, where X is the weight value, μ is the mean, and σ is the standard deviation.

For the lower bound of 108 lb:

Z1 = (108 - 143) / 29 = -35 / 29 ≈ -1.2069

For the upper bound of 175 lb:

Z2 = (175 - 143) / 29 = 32 / 29 ≈ 1.1034

Using a Z-table or a calculator, we can find the corresponding probabilities associated with Z1 and Z2.

The probability of a woman's weight being between 108 lb and 175 lb is given by:

P(108 lb ≤ X ≤ 175 lb) = P(Z1 ≤ Z ≤ Z2)

Using the Z-table or a calculator, we can find these probabilities and calculate the difference between them.

(b) Probability for 4 women's mean weight between 108 lb and 175 lb:

To find the probability that the mean weight of 4 randomly selected women falls within the range of 108 lb to 175 lb, we need to consider the distribution of sample means. The mean of the sample means (μ') will still be the same as the population mean (μ), but the standard deviation of the sample means (σ') is calculated as σ / √n, where n is the sample size.

For n = 4, σ' = 29 / √4 = 29 / 2 = 14.5 lb.

We can then calculate the Z-scores for the lower and upper bounds using the formula mentioned earlier. Let's denote the Z-scores as Z1' and Z2'.

For the lower bound of 108 lb:

Z1' = (108 - 143) / 14.5 ≈ -2.4138

For the upper bound of 175 lb:

Z2' = (175 - 143) / 14.5 ≈ 2.2069

Using a Z-table or a calculator, we can find the probabilities associated with Z1' and Z2', which represent the probability of the mean weight falling between 108 lb and 175 lb.

(c) Probability for 89 women's mean weight between 108 lb and 175 lb:

Following the same approach as in (b), we can calculate the standard deviation of the sample means for a sample size of 89:

For n = 89, σ' = 29 / √89 ≈ 3.0755 lb.

We can then calculate the Z-scores for the lower and upper bounds using the formula mentioned earlier. Let's denote the Z-scores as Z1'' and Z2''.

For the lower bound of 108 lb:

Z1'' = (108 - 143) / 3.0755 ≈ -11.3405

For the upper bound of 175 lb:

Z2'' = (175 - 143) / 3.0755 ≈ 10.3904

Using a Z-table or a calculator, we can find the probabilities associated with Z1'' and Z2'', which represent the probability of the mean weight falling between 108 lb and 175 lb for a sample of 89 women.

Step-by-step explanation:

To evaluate an expression we need to find the numerical value of the expression by substituting appropriate values for the variables and performing the indicated mathematical operations.

Given rational expression:

\(\dfrac{6x^2}{y^3}\)

To evaluate the given expression when x = 6 and y = 2, substitute x = 6 and y = 2 into the expression and solve.

\(\dfrac{6(6)^2}{(2)^3}\)

Following the order of operations, begin by evaluating the exponents first.

To square a number, we multiply it by itself.

\(\implies 6^2 = 6 \times 6 = 36\)

To cube a number, we multiply it by itself twice.

\(\implies 2^3 = 2 \times 2 \times 2 = 8\)

Therefore:

\(\dfrac{6(6)^2}{(2)^3}=\dfrac{6 \cdot 36}{8}\)

Multiply the numbers in the numerator:

\(\dfrac{216}{8}\)

Finally, divide 218 by 8:

\(\dfrac{216}{8}=27\)

Therefore, the evaluation of the given expression when x = 6 and y = 2 is 27.

\(\hrulefill\)

As one calculation:

\(\begin{aligned}x=6, y=2 \implies \dfrac{6x^2}{y^3}&=\dfrac{6(6)^2}{(2)^3}\\\\&=\dfrac{6 \cdot 36}{8}\\\\&=\dfrac{216}{8}\\\\&=27\end{aligned}\)

The area of the rectangle is 17 square units.

The area of a rectangle is the product between the two dimensions (length and width) of the rectangle.

Here we know that the vertices are:

A(-1, 9), B(0, 9), C(0, -8), D(-1, -8)

We can define the length as the side AB, which has a lenght:

L = (-1, 9) - (0, 9) = (-1 - 0, 9 - 9) = (-1, 0) ----> 1 unit.

And the width as BC, which has a length:

L = (0, 9) - (0, -8) = (0 - 0, 9 + 8) = (0, 17) ---> 17 units.

The critical path is the path with the longest duration, which in this case is A -> B -> D -> E with a duration of 11 days.

To determine the critical path of the project, we need to find the longest path of activities that must be completed in order to finish the project on time. This is done by calculating the earliest start time (ES) and earliest finish time (EF) for each activity.

Starting with activity A, ES = 0 and EF = 4. Activity B can start immediately after A is complete, so ES = 4 and EF = 7. Activity C can start after A is complete, so ES = 4 and EF = 6. Activity D can start after B is complete, so ES = 7 and EF = 9. Finally, activity E can start after C and D are complete, so ES = 9 and EF = 11.

The variance for each activity is also given, which allows us to calculate the standard deviation and determine the probability of completing the project on time. The critical path is the path with the longest duration, which in this case is A -> B -> D -> E with a duration of 11 days.

Using the expected durations and variances, we can calculate the standard deviation of the critical path. This information can be used to determine the probability of completing the project on time.

Answer:

Independent Variable, Domain = Charity amount

Dependent Variable, Range = Donation amount

Step-by-step explanation:

Independent Variable is the causal variable. Dependent variable is the resultant or effected variable.

In this case, organisation donates money, a constant value (250) & a proportion (half) of charity. So, independent variable (causal) is charity, effecting the dependent variable ie donation.

Equation : Let donation = d, charity = c. Given : d = f (c) , where d = 250 + c/2

Domain is set of of all values for which a function is defined, range is the set of all values that f takes. So, domain is independent variable - charity & range is dependent variable - donation.
