Answer 1

Answer:

1.  4   2. 2   3. Does not exist   4. Does not exist   5. 3

Step-by-step explanation:

1. This is the limit as x approaches 2 from the left.  That means that x "sneaks up" on 2, but from the left (ironically moving right). As  x  does that, the graph rises, heading for 4 (even though the point is "empty").  The limit is 4.  See attached image 1

2. Let  x  sneak up on 2 from the right (so moving left towards 2). As x does that, the graph falls, heading for the y-value 2.  The limit is 2.  See image 2.

3. This limit (two-sided) does not exist because the one-sided limits had different values.

4. This limit does not exist, either.  The limit as x approaches 0 from the left is 4.  The limit as x approaches 0 from the right is 0.  These are different, so the two-sided limit is not defined.

5. g(2) = 3, where the solid dot is.  It's the value of the function at x=2.

Answers

Answer:

the length is 8ft

the width is 3ft

Step-by-step explanation:

Step one:

given

perimter= 22ft

let the length be x

width = x-5

Step two

the expression for the perimeter of a rectangle is

P=2L+2W

substituting our data

22= 2(x)+2(x-5)

open brackets

22=2x+2x-10

collect terms and solve for x

22+10=4x

32=4x

divide both sides by 4

x= 32/4

x= 8ft

Amiron buys a tarp to cover that area under his tent tent has an area of 5 ft. ² the tarp bought is 2 2/3’ x 2 1/4’ will the tide be big enough to cover the area under Amiron’s tent?

Answers

The tarp bought by Amiron, which has dimensions of 2 2/3' x 2 1/4', may not be big enough to cover the area under his tent, which has an area of 5 ft².

To determine if the tarp is big enough to cover the area under Amiron's tent, we need to compare the dimensions of the tarp to the area of the tent.

The area of the tarp can be calculated by multiplying its length and width. In this case, the tarp has dimensions of 2 2/3' x 2 1/4'. Converting these mixed numbers to improper fractions, we have 8/3' x 9/4'. Multiplying these fractions gives us an area of (8/3) x (9/4) = 72/12 = 6 ft².

Comparing the area of the tarp (6 ft²) to the area of the tent (5 ft²), we can see that the tarp is larger than the tent. Therefore, the tarp is big enough to cover the area under Amiron's tent.

It is important to note that it's ideal to have a tarp that is larger than the area to be covered, as it provides better coverage and protection. In this case, the tarp is larger than the tent, which should be sufficient for covering the area underneath.

find the maximum value m of (,)=25f(x,y)=x2y5 for ≥0,x≥0, ≥0y≥0 on the line =1.x y=1. (use symbolic notation and fractions where needed.)

Answers

The maximum value of f(x, y) = \(x^2 * y^5\) subject to the given constraints is approximately 0.06715.

To find the maximum value of f(x, y) = \(x^2 * y^5\)subject to the constraints x ≥ 0, y ≥ 0, and x + y = 1, we can use the method of Lagrange multipliers.

First, let's define the Lagrangian function L(x, y, λ) as:

L(x, y, λ) =\(x^2 * y^5\) + λ(x + y - 1)

We need to find the critical points of L(x, y, λ) by taking partial derivatives with respect to x, y, and λ, and setting them equal to zero:

∂L/∂x = \(2xy^5\)+ λ = 0

∂L/∂y = \(5x^2y^4\)+ λ = 0

∂L/∂λ = x + y - 1 = 0

From the first equation, we have:

\(2xy^5\)+ λ = 0

λ = -2xy^5

Substituting this into the second equation:

\(5x^2y^4 - 2xy^5\) = 0

\(xy^4(5x - 2y)\) = 0

This equation gives us two possible cases:

\(xy^4 = 0\)

This implies that either x = 0 or y = 0.

5x - 2y = 0

This implies that 5x = 2y, or x = (2/5)y.

Now let's consider each case separately:

\(Case 1: xy^4 = 0\)

a) If x = 0, then the constraint x + y = 1 gives us y = 1.

So the point (x, y) = (0, 1) satisfies the constraints.

b) If y = 0, then the constraint x + y = 1 gives us x = 1.

So the point (x, y) = (1, 0) satisfies the constraints.

Case 2: x = (2/5)y

Substituting this into the constraint x + y = 1:

(2/5)y + y = 1

(7/5)y = 1

y = 5/7

Plugging y = 5/7 back into x = (2/5)y:

x = (2/5)(5/7) = 2/7

So the point (x, y) = (2/7, 5/7) satisfies the constraints.

Now, we need to evaluate the function \(f(x, y) = x^2 * y^5\) at each of these critical points:

f(0, 1) = 0

f(1, 0) = 0

\(f(2/7, 5/7) = (2/7)^2 * (5/7)^5\)

To find the maximum value, we compare these values:

Maximum value m =\((2/7)^2 * (5/7)^5\)

Calculating this expression, we get:

m ≈ 0.06715

Therefore, the maximum value of f(x, y) = \(x^2 * y^5\) subject to the given constraints is approximately 0.06715.

In ABC, A = 50 and the external bisectors of B and C meet at O as shown in figure. The measure of BOC

Answers

Answer:

17

Step-by-step explanation:

Look at Triangle ABC, The rays meet at line BC and they are both from the interior point A. So this means that AB=AC. This makes ABC a isosceles triangle. Using the isosceles triangle theorem, Angle B and Angle C measure is equal to each other so

\(50 + x + x = 180\)

\(50 + 2x = 180\)

\(2x = 130\)

\(x = 65\)

This means angle b and C of the triangle ABC measure is 65.

External bisector bisect a figure that it makes the original angle split into half that they are equal to each other.

This means the angle below Angle B and angle C measure is 32.5. We can find the measure of Angle B and C in triangle BOC. This is a isosceles triangle as well so

\(32.5 + 65 + x = 180\)

\(98.5 + x = 180\)

\(x = 81.5\)

Angle C is 81.5 as well so

\(81.5 + 81.5 = 163\)

Find angle o

\(180 - 163 = 17\)

Explain how the sine of an angle in the second quadrant differs from the sine of its reference angle in the unit circle

Answers

The sine of an angle in the second quadrant differs from the sine of its reference angle by a negative sign.

In the unit circle, the reference angle is the acute angle formed between the positive x-axis and the terminal side of an angle measured counterclockwise. The sine of an angle is defined as the y-coordinate of the point on the unit circle corresponding to that angle.

In the second quadrant of the unit circle, angles have values between 90 degrees and 180 degrees (π/2 and π radians). Since the reference angle is always the acute angle, the reference angle for an angle in the second quadrant is the angle formed between the terminal side and the negative x-axis.

When comparing the sine of an angle in the second quadrant to the sine of its reference angle, there is a sign difference. The sine function is positive in the first and second quadrants. However, in the second quadrant, the y-coordinate (sine value) is negative because it lies below the x-axis. This means that the sine of an angle in the second quadrant is the negative value of the sine of its reference angle.

Mathematically, if θ is an angle in the second quadrant, and α is its reference angle, then:

sin(θ) = -sin(α)

This relationship holds true because the y-coordinate (sine value) in the second quadrant is the negative value of the y-coordinate in the first quadrant. So, the sine of an angle in the second quadrant differs from the sine of its reference angle by a negative sign.

a school district wants to justify building a new elementary school in the district because it believes that the expected number of students will start to exceed the capacity of the schools in the district. which statistical method would be most appropriate? group of answer choices binomial distribution confidence interval hypothesis test regression analysis

Answers

The answer is that regression analysis is the most appropriate method.

The most appropriate statistical method to justify building a new elementary school in the district would be regression analysis. This method can be used to examine the relationship between the expected number of students and the capacity of the schools in the district.



Regression analysis is a statistical method that helps to determine the relationship between two or more variables. In this case, the expected number of students would be the independent variable, while the capacity of the schools in the district would be the dependent variable. By analyzing the relationship between these variables, the school district can make predictions about how many students will need to be accommodated in the future and whether a new elementary school is necessary.

In contrast, binomial distribution is a statistical method that is used to calculate the probability of a specific number of successes in a set of trials, which would not be suitable for this situation. Confidence intervals and hypothesis tests are statistical methods used to draw conclusions about populations based on sample data, but may not be the most appropriate method for this situation.

You can infer causality from a correlational result, but only when the r value is greater than ?A. 0B. 5C. 1

Answers

You can infer causality from a correlational result, but only when the r value is greater than:

C. 1

Causality refers to a situation in which one event causes another. When there is a correlation between two variables, it means that they tend to move in the same direction.

However, this does not necessarily mean that one event causes the other. In order for a correlation to indicate causality, the correlation coefficient (r) must be greater than 1. If the correlation coefficient is below 1, then there is not enough evidence to suggest that one event causes the other.

In addition, there are other factors that need to be considered when assessing causality from a correlational result.

For example, the strength of the relationship between the variables, the direction of the relationship, and the consistency of the results over time. It is also important to consider the context in which the research was conducted, as this may have an effect on the results.

Answers

The vertex form of the equation is y = (x - 3)² - 4, which corresponds to option OD.

To convert the given equation from standard form to vertex form, we need to complete the square.

The vertex form of a parabola's equation is y = a(x-h)² + k, where (h, k) represents the vertex of the parabola.

Given equation: y = x² - 6x + 14

Move the constant term to the right side:

y - 14 = x² - 6x

Complete the square by adding and subtracting the square of half the coefficient of x:

y - 14 + 9 = x² - 6x + 9 - 9

Group the terms and factor the quadratic:

(y - 5) = (x² - 6x + 9) - 9

Rewrite the quadratic as a perfect square:

(y - 5) = (x - 3)² - 9

Simplify the equation:

y - 5 = (x - 3)² - 9

Move the constant term to the right side:

y = (x - 3)² - 9 + 5

Answers

The expression in terms of first powers of cosine of multiple angles using power-reducing formulas is (1/4) + (1/2)cos6x + (1/4)cos²6x.

The power-reducing formulas are formulas that allow us to rewrite any expression that contains even powers of sine or cosine functions into expressions that contain only odd powers of sine or cosine functions.

Suppose we want to rewrite the expression cos^4(3x) in terms of first powers of cosine of multiple angles using power-reducing formulas.

The formula is given as:

cos²θ = (1 + cos2θ)/2

From the formula, we can write cos⁴θ = (cos²θ)²

So, cos⁴θ = [(1 + cos2θ)/2]²

By substituting 3x for θ, we have:

cos⁴(3x) = [(1 + cos6x)/2]²

Therefore, the expression in terms of first powers of the cosines of multiple angles is [(1 + cos6x)/2]².

Now, we have the following expression for the money Alex has:

3.63+x

Now, we have:

x+3.63+x = 27.93

2x+3.63 = 27.93

Subtracting 3.63 from both the sides:

2x = 27.93-3.63

2x = 24.3

Dividing by 2 on both the sides:

x = 24.3/2

x = $12.15

So, Rick has $12.15.

Answers

For D:

A triangle always has 180 degrees total. No more, no less. Seeing as though all the sides and angles are the same length, we can just divide 180 by 3, giving us 60. x = 60 degrees.

For E:

We can see there is a 90 degree symbol that surmises both angles. We know the lower angle is 30 degrees, so m must equal 60 degrees.

For G:

Same concept as D, except we gotta do a bit of math. A triangle always has 180 degrees, So we add 50 and 55 together and get 105. Subtract 105 from 180 and we get 75. Therefore, your angle is 75 degrees.

For H:

The 75 degree angle and m are parallel, with the same line passing through it, meaning that m is identical to the other angle. m = 75.

Answer:

d) x = 60

e) m = 60

g) q = 75

h) m = 75

Step-by-step explanation:

d) This image is that of an equilateral triangle, or a triangle whose sides are all equal (also known as a regular triangle). One property of an equilateral triangle is that all of its angles are also equal. Because the angles of a triangle add up to 180° (Triangle Sum Theorem), each angle would be 180/3°, or 60°, so x = 60.

e) This problem shows two complementary angles. Complementary angles are two angles that add up to 90°. Because one of the angles is given, you can find the other by subtracting the given one from 90°:

   m = 90 - 30

   m = 60

g) This is an image of a triangle with two given angles and the missing one is the third angle, q. You can solve for q using the Triangle Sum Theorem, which states that the three interior angles of a triangle add to 180°:

   50 + 55 + q = 180

   105 + q = 180

   q = 75

h) This image shows two parallel lines cut by a transversal. You can find m using the Corresponding Angles Theorem, which states that if parallel lines are cut by a transversal, the corresponding angles will be congruent. Because the lines are parallel, you know that m = 75 since the 75° angle is its corresponding angle.
