State the slope and y-intercept of the line with equation y=4+3x.

By using Pythagorean theorem and derivatives, we find the distance between the boy and the balloon is increasing at a rate of 16 ft/s, 5 seconds after the boy passes under the balloon.

We can use the Pythagorean theorem to relate the distance between the boy and the balloon, the height of the balloon, and the distance the boy has traveled:

distance^2 = height^2 + (distance traveled by the boy)^2

Taking the derivative with respect to time, we have:

2(distance)(rate of change of distance) = 2(height)(rate of change of height) + 2(distance traveled by the boy)(rate of change of distance traveled by the boy)

Simplifying and solving for the rate of change of distance, we get:

rate of change of distance = [(height)(rate of change of height) + (distance)(rate of change of distance traveled by the boy)] / distance

At the moment the boy passes under the balloon, we have:

distance = 40 ft

height = 40 ft

rate of change of height = 4 ft/s (since the balloon is rising at a speed of 4 ft/s)

distance traveled by the boy = 16 ft/s x 5 s = 80 ft

rate of change of distance traveled by the boy = 16 ft/s (since the boy is cycling at a constant speed of 16 ft/s)

Substituting these values into the equation above, we get:

rate of change of distance = [(40 ft)(4 ft/s) + (40 ft)(16 ft/s)] / 40 ft = 16 ft/s

Therefore, the distance between the boy and the balloon is increasing at a rate of 16 ft/s, 5 seconds after the boy passes under the balloon.

We can see the ratio of A/B is same for the first three rows of the table:

Assume the same ratio applies to the last row, then:

Correct choice is A.

The answer of the given question based on the circle on finding the angle congruent to angle ∠MPO is Angle ∠MPN is congruent to angle ∠MPO.

Congruent angles are angles that have the same measure or size, in other words, they are identical in terms of their angle measure. Two angles are congruent if they have the same angle measure, even if their orientation or position is different. Formally, if two angles have the same measure, they are denoted by the symbol ≅, which means "congruent". For example, ∠ABC ≅ ∠DEF means that angle ∠ABC is congruent to angle ∠DEF.

Congruent angles have the same properties, such as being supplementary, complementary, or vertical, and they can be used interchangeably in geometric proofs and constructions.

Angle ∠MPN is congruent to angle ∠MPO.

This is because angle ∠MPN and angle ∠MPO are both inscribed angles that subtend the same arc PO on circle M, and therefore they are congruent according to the Inscribed Angle Theorem.

The number of tomato slices, t and the number of hamburgers, h is t=2h

A ratio is a mathematical relationship between two or more numbers that shows how much one value is proportional to another. It is expressed in the form of a fraction or as a colon between the two values.

Since each hamburger gets the same number of slices of tomatoes, we can assume that the relationship between the number of tomato slices, t, and the number of hamburgers, h, is a proportional relationship.

To find the constant of proportionality, we can choose any two sets of data from the table and calculate the ratio of tomato slices to the number of hamburgers:

For the first two days: 72/36 = 2, or 100/50 = 2

For the last two days: 150/75 = 2, or 200/100 = 2

Since the ratios are all equal, we can conclude that the equation representing the relationship between t and h is:

Ht = 2h

Linear Programming problem:

Given a linear programming problem with the objective function to minimize, we have to construct the first table and identify the pivot element.

The given objective function is:

Minimize c = 3000x + 2000y

The given constraints are:

20x + 10y > 200

25x + 50y > 500

8x + 4y > 300

Let x, y, z, > 0

To construct the first table, we need to introduce slack variables. We need to write all the inequalities in the standard form, i.e., Ax + By + Cz ≤ K.

Inequality 1: 20x + 10y > 200 ⇒ 20x + 10y - s₁ = 200

Inequality 2: 25x + 50y > 500 ⇒ 25x + 50y - s₂ = 500

Inequality 3: 8x + 4y > 300 ⇒ 8x + 4y - s₃ = 300

To construct the first table, we need to create a table with a slack variable for each constraint. The coefficients of x and y will be kept in the same row, and the slack variable will be placed in the next column.

Then, the right-hand side of each constraint will be put in the final column. The last row will be filled with coefficients of the objective function. Hence, the first table is:

Variable 20x + 10y - s₁ 25x + 50y - s₂ 8x + 4y - s₃ RHS s₁ s₂ s₃ Coefficient 3000 2000 13000

To identify the pivot element, we have to use the minimum ratio test. This test helps us to choose the pivot element by finding the smallest non-negative ratio of the constant in the objective row to the constant in the row for each variable.

The minimum ratio test for variable x:

s₁/20 = 200/20 = 10

s₂/25 = 500/25 = 20

s₃/8 = 300/8 = 37.5

The smallest ratio is for variable x in the first row. Hence, the pivot element is 20.

The table after pivoting:

Variable 20x + 10y - s₁ 25x + 50y - s₂ 8x + 4y - s₃ RHS s₁ s₂ s₃ Coefficient 3000 2000 13000 New Row -2x + y + s₁ - 2s₂ - 4s₃ = -300 New Row/(-2) x - y - s₁/(-2) + s₂ + 2s₃/(-2) = 150

The second table after pivoting and computing the new row is:

Variable 20x + 10y - s₁ 25x + 50y - s₂ 8x + 4y - s₃ RHS s₁ s₂ s₃ Coefficient 3000 2000 13000 New Row -2x + y + s₁ - 2s₂ - 4s₃ = -300 New Row/(-2) x - y - s₁/(-2) + s₂ + 2s₃/(-2) = 150

The optimal solution is found where x = 75, y = 75, z = 0, and c = 450000. The pivot element is 20.

Answer:

1.  D. (7, 0.5)

2. 0 and 1

Step-by-step explanation:

1. The question says to estimate the best solution for the two equations. They are looking for the point of intersection for the two lines. Choices B and C aren't on either line, and Choice A only lies on the first line, so it is not a solution to both equations. You can also check this:  Add the two equations such that 2y = 1;  y = 0.5, the coordinate for Option D.

2. This time, the question is only looking for values of x that satisfy the equation. You can look at the graph and see that the two functions intersect at (0,2). 0 is the x-coordinate for this point so it is one of the answers. The second intersection point lies on x = 1, we can't tell what the y-value is at that point, but it doesn't matter because the question is only looking for x-values.

You can check both of these numbers by substituting them into the equation where f(x) and g(x) are set equal to each other.

Check for 0

[tex]-\frac{3}{4} (0) +2 = \frac{1}{4}^0 +1\\0+2 = 1+1\\2=2\\[/tex]            Note that any number raised to the 0 power is 1.

Check for 1

[tex]-\frac{3}{4}(1)+2 = \frac{1}{4}^1+1\\ \\-\frac{3}{4} +2 = \frac{1}{4} + 1\\ \\\frac{5}{4} = \frac{5}{4}[/tex]

So the solutions to f(x) = g(x) are x = 0, 1.

The integration of  y′ = 2e^2x sin (e^2x) ⇒ y =_____+C is y = e^2x sin(e^2x) - (4/5)e^5x cos(e^2x) - (8/25)∫e^7x sin(e^2x) dx + C

To solve this integration problem, we need to use integration by parts. Integration by parts is a technique for evaluating integrals where the standard integration rules do not apply. The formula for integration by parts is ∫u dv = uv - ∫v du.

Let u = sin(e^2x) and dv = 2e^2x dx

Then, du = 2e^2x cos(e^2x) dx and v = e^2x

Using the formula for integration by parts, we get:

∫2e^2x sin(e^2x) dx = e^2x sin(e^2x) - ∫e^2x * 2e^2x cos(e^2x) dx

= e^2x sin(e^2x) - 2∫e^4x cos(e^2x) dx

Now, we need to use integration by parts again. Let u = cos(e^2x) and dv = 2e^4x dx

Then, du = -2e^2x sin(e^2x) dx and v = (2/5)e^5x

Using the formula for integration by parts, we get:

∫2e^4x cos(e^2x) dx = (2/5)e^5x cos(e^2x) - (2/5)∫(2/5)e^5x * -2e^2x sin(e^2x) dx

= (2/5)e^5x cos(e^2x) + (4/25)∫e^7x sin(e^2x) dx

Now, we can substitute this back into the original equation:

y = e^2x sin(e^2x) - 2[(2/5)e^5x cos(e^2x) + (4/25)∫e^7x sin(e^2x) dx] + C

Unfortunately, the integral ∫e^7x sin(e^2x) dx does not have a simple solution, so we cannot simplify this further. However, we have found the most simplified form of the integral in terms of another integral. The final answer is:

y = e^2x sin(e^2x) - (4/5)e^5x cos(e^2x) - (8/25)∫e^7x sin(e^2x) dx + C

To rank data sets from the smallest to largest standard deviation, we need to look at the spread of the data in each histogram. The standard deviation is a measure of how spread out the data is. If the data is closely clustered around the mean, the standard deviation will be small. If the data is spread out over a wider range, the standard deviation will be larger.

To determine the standard deviation of each data set, we can look at the width of the histogram. A narrower histogram indicates a smaller standard deviation, while a wider histogram indicates a larger standard deviation.

Based on this information, we can rank the data sets from smallest to largest standard deviation by looking at the width of the histograms and ordering them from narrowest to widest.

The percent of this older population that has osteoporosis is 31%.Hence, the answers given at the back of the book are correct.

The percentage of healthy young adults having osteoporosis by the WHO criterion is 0.6%.The World Health Organization criterion for osteoporosis is a BMD 2.5 standard deviations below the mean for young adults. As we know that BMD measurements in a population of people similar in age and sex follow roughly a normal distribution, the mean and the standard deviation for this distribution are given as follows:

Mean: 0 Standard deviation: 1 The z-score for the BMD measurement of a person with osteoporosis is:z = (−2.5 − 0)/1 = −2.5Thus, the probability that a healthy young adult has osteoporosis according to the WHO criterion isP(z < −2.5) = 0.0062 = 0.62%.

Therefore, the percentage of healthy young adults who have osteoporosis by the WHO criterion is 0.6%.b) The percentage of the older population that has osteoporosis is 31%.Women aged 70 to 79 are not young adults. The mean BMD in this age group is about −2 on the standard scale for young adults. As we know that the standard deviation is the same as that for young adults.

Therefore, we can standardize the BMD scores for the older population as follows:Mean: −2 Standard deviation: 1The z-score for the BMD measurement of a person with osteoporosis is:z = (−2.5 − (−2))/1 = −0.5 The area to the left of this z-score in the standard normal distribution is:P(z < −0.5) = 0.3085 = 30.85%Therefore, the percent of this older population that has osteoporosis is 31%.Hence, the answers given at the back of the book are correct.

In exploration 4.3.3, the vertical asymptote for question 2 is at x = -2. Let's see what is meant by a vertical asymptote.What is a vertical asymptote?A vertical asymptote is a line that a function approaches but never touches.

The curve gets arbitrarily close to the vertical line but never touches it. When the function approaches a vertical asymptote, the function approaches infinity or negative infinity.For instance, consider the function f(x) = 1/x. It has a vertical asymptote at x = 0. This is because the function's value becomes increasingly larger as x approaches 0 from the positive side, and the value of the function becomes increasingly smaller as x approaches 0 from the negative side.Therefore, if a curve goes on increasing or decreasing on both sides of a vertical line (called a vertical asymptote), the curve approaches that line but never touches it. This is the basic idea of a vertical asymptote.What is the vertical asymptote for question 2?The rational function f(x) = (x + 2) / [(x + 2)^2 - 4] is being studied in question 2 of exploration 4.3.3. It can be seen that (x + 2)^2 - 4 = (x + 2 - 2)(x + 2 + 2) = (x)(x + 4).Therefore, the denominator (x + 2)^2 - 4 can be written as (x)(x + 4).The vertical asymptotes of a rational function occur where the denominator equals zero. Since the denominator is (x)(x + 4), the vertical asymptotes occur where x = 0 or x = -4.However, x = 0 is not a vertical asymptote because there is a hole in the graph. So, the only vertical asymptote is at x = -2. This means that the curve approaches x = -2 but never touches it. Therefore, the vertical asymptote for question 2 in exploration 4.3.3 is x = -2.
