How you would work through this kind of problem, or at least how I would approach it weight out the pros and cons of each graph, or put some data on different graphs and see what works best. On the contrary if you have a rough idea of how each graph would look like you would just chose the one you think conveys the information best.

The function f(x) = 4 is continuous at x = 1 and the derivative of f(x) = cos⁻¹(3x² - 5) is f'(x) = -6x * sin(cos⁻¹(3x² - 5)).

To determine if the function f(x) = 4 is continuous at x = 1, we need to check if the limit of f(x) as x approaches 1 is equal to f(1).

The given function f(x) = 4 is a constant function, which means its value is the same for all values of x. In this case, f(x) = 4 for all x.

So, the limit of f(x) as x approaches 1 is:

lim(x→1) f(x) = lim(x→1) 4 = 4

And f(1) = 4

Since the limit and the value of f(x) at x = 1 are the same (both equal to 4), the function f(x) = 4 is continuous at x = 1.

To obtain the derivative of f(x) = cos⁻¹(3x² - 5), we can use the chain rule.

Using the chain rule, we have:

f'(x) = -sin(cos⁻¹(3x² - 5)) * d/dx(3x² - 5)

To differentiate 3x² - 5, we get:

d/dx(3x² - 5) = 6x

Substituting back into the equation:

f'(x) = -sin(cos⁻¹(3x² - 5)) * 6x

It's B, -2, v/5 4, and 3².

a)The sample sizes are n1 = 379 and n2 = 573. The Z-score for a 90% confidence level is approximately 1.645.
b)The confidence interval contains both positive and negative numbers, it means that the true difference between the population proportions can be either positive or negative.

(a) To find the 90% confidence interval for pi - p2, we can use the formula:

CI = (p1 - p2) ± Z * sqrt((p1 * (1 - p1) / n1) + (p2 * (1 - p2) / n2))

where p1 is the proportion of couples with three preferences in common, p2 is the proportion of couples with two preferences in common, n1 is the sample size for couples with three preferences in common, n2 is the sample size for couples with two preferences in common, and Z is the Z-score corresponding to a 90% confidence level.

From the information provided, p1 = 134/379 = 0.353 and p2 = 215/573 = 0.375. The sample sizes are n1 = 379 and n2 = 573. The Z-score for a 90% confidence level is approximately 1.645.

Plugging these values into the formula, we get:

CI = (0.353 - 0.375) ± 1.645 * sqrt((0.353 * (1 - 0.353) / 379) + (0.375 * (1 - 0.375) / 573))

Calculating this expression, we find that the lower limit of the confidence interval is -0.047 and the upper limit is 0.029.

Therefore, the 90% confidence interval for pi - p2 is approximately -0.047 to 0.029.

(b) In the context of this problem, the confidence interval in part (a) means that we are 90% confident that the true difference between the population proportions of couples with three preferences in common and couples with two preferences in common falls between -0.047 and 0.029.

Since the confidence interval contains both positive and negative numbers, it means that the true difference between the population proportions can be either positive or negative.

The exercise involves finding the product C = AB, where matrix A is given by [2 9] and matrix B is given by [3 6 1]. We need to perform the matrix multiplication to obtain the resulting matrix C.

Let's calculate the matrix product C = AB step by step:

Matrix A has dimensions 2x1, and matrix B has dimensions 1x3. To perform the multiplication, the number of columns in A must match the number of rows in B.

In this case, both matrices satisfy this condition, so the product C = AB is defined.

Calculating AB:

AB = [23 + 912 26 + 94 21 + 95]

[103 + 612 106 + 64 101 + 65]

Simplifying the calculations:

AB = [6 + 108 12 + 36 2 + 45]

[30 + 72 60 + 24 10 + 30]

AB = [114 48 47]

[102 84 40]

Therefore, the product C = AB is:

C = [114 48 47]

Symbolically, they correspond to the relationships between the coefficients of the equations.

A system of 2 linear equations in 2 variables can have one of the following three possible solutions:

One unique solution: In this case, the two lines intersect at exactly one point, and this point is the solution to the system. Visually, the two lines are not parallel, but they are not the same either. Symbolically, the system is represented as:

a1x + b1y = c1

a2x + b2y = c2

where a1, b1, c1, a2, b2, and c2 are constants, and x and y are variables.

Infinitely many solutions: In this case, the two lines coincide and are on top of each other, meaning they have the same slope and the same y-intercept. Visually, the two lines are identical. Symbolically, the system is represented as:

a1x + b1y = c1

ka1x + kb1y = kc1

where a1, b1, and c1 are constants, x and y are variables, and k is any non-zero constant.

No solution: In this case, the two lines are parallel and never intersect. Visually, the two lines are distinct and never meet. Symbolically, the system is represented as:

a1x + b1y = c1

a2x + b2y = c2

where a1, b1, c1, a2, b2, and c2 are constants, and x and y are variables, and the slope of one line is not equal to the slope of the other.

a.  the estimated area under the graph of f(x) = 10√x from x = 0 to x = 4 is R4 = 1. b. Using four approximating rectangles and left endpoints, the estimated area under the graph of f(x) = 10√x from x = 0 to x = 4 is L4 =1

(a) Using four approximating rectangles and right endpoints, the estimated area under the graph of f(x) = 10√x from x = 0 to x = 4 is R4 = _______.

To estimate the area using right endpoints, we divide the interval [0, 4] into four subintervals of equal width. The width of each subinterval is Δx = (4 - 0) / 4 = 1.

For each subinterval, we take the right endpoint as the x-value to determine the height of the rectangle. The height of the rectangle is given by f(x) = 10√x. Therefore, the right endpoint of each subinterval will be the x-value plus the width of the subinterval, i.e., x + Δx.

We calculate the area of each rectangle by multiplying the width (Δx) by the height (f(x)) for each subinterval. Finally, we sum up the areas of all four rectangles to obtain the estimated area under the graph.

Performing the calculations, we have:

R4 = Δx * (f(1) + f(2) + f(3) + f(4))

Substituting the values, we get:

R4 = 1 * (10√1 + 10√2 + 10√3 + 10√4)

Simplifying this expression and rounding the answer to four decimal places will give us the estimated area under the graph using four approximating rectangles and right endpoints.

(b) Using four approximating rectangles and left endpoints, the estimated area under the graph of f(x) = 10√x from x = 0 to x = 4 is L4 = _______.

To estimate the area using left endpoints, we follow a similar process as in part (a), but this time we take the left endpoint of each subinterval as the x-value to determine the height of the rectangle.

We calculate the area of each rectangle by multiplying the width (Δx) by the height (f(x)) for each subinterval, using the left endpoint as the x-value. Finally, we sum up the areas of all four rectangles to obtain the estimated area under the graph using left endpoints.

Performing the calculations in a similar manner as in part (a) and rounding the answer to four decimal places will give us the estimated area under the graph using four approximating rectangles and left endpoints.

You want to know angles x, y, and z in the given figure where parallel lines 'a' and 'b' are crossed by a transversal. The sum of these angles is 290°.

Angles y and z are called consecutive interior angles. As such, they are supplementary, so their sum is 180°.

  x + y + z = 290°

  x + 180° = 290°

  x = 110°

Angles x and y are vertical angles, so are congruent.

  y = x = 110°

Then z is found from ...

  y + z = 180°

  110° + z = 180°

  z = 70°

The measures of x, y, and z are 110°, 110°, and 70°, respectively.

Assuming everything else stays the same, an increase in the price of smartphones will decrease the quantity supplied of smartphones. Option c is the correct answer.

This is because the quantity supplied is the number of smartphones that suppliers are willing and able to sell at a given price, while supply refers to the entire range of quantities that suppliers are willing and able to sell at different prices.

When the price of smartphones increases, the cost of production and supply also increases. This leads to a decrease in the profitability of supplying smartphones at the current market price, and hence suppliers reduce the quantity supplied.

As a result, the quantity supplied of smartphones decreases, causing a leftward shift in the supply curve.

However, it is important to note that a decrease in the quantity supplied does not mean that there is a decrease in demand for smartphones. The demand for smartphones could remain the same, or even increase, leading to a shortage of smartphones in the market.

Therefore, the correct option is c.

Driving a personal car would be the most cost-effective mode of transportation for this commute, with a total daily cost of approximately $4.60 ($3.60 for gas + $1 for travel time).

Based on the given information, the most cost-effective mode of transportation for this commute would be to drive a personal car. Taking public transportation or carpooling may be more environmentally friendly options, but they may not save as much money as driving alone.

Assuming an average speed of 60 miles per hour on the highway, the commute would take approximately 20 minutes each way, or 40 minutes round-trip. This means the total cost of travel time for each workday would be $40 ($60/hour x 2/3 hour).

Using a cost calculator such as GasBuddy, we can estimate that the cost of driving 20 miles per day (round-trip) would be around $3.60 per day, assuming an average fuel efficiency of 25 miles per gallon and a gasoline price of $2.50 per gallon.

The given initial value problem is a second-order linear homogeneous differential equation. To solve it, we first find the characteristic equation by substituting y = e^(rx) into the equation. This leads to the characteristic equation r^2 - 10r + 50 = 0.

The general solution of the differential equation is y(x) = e^(5x)(C₁cos(5x) + C₂sin(5x)), where C₁ and C₂ are constants determined by the initial conditions.

To determine the particular solution, we differentiate y(x) to find y'(x) = e^(5x)(5C₁cos(5x) + 5C₂sin(5x) - C₂cos(5x) + C₁sin(5x)), and then differentiate y'(x) to find y''(x) = e^(5x)(-20C₁sin(5x) - 20C₂cos(5x) - 10C₂cos(5x) + 10C₁sin(5x)).

Substituting the initial conditions y(0) = 1 and y'(0) = 5 into the general solution and its derivative, we obtain the following equations:

1 = C₁,

5 = 5C₁ - C₂.

Solving these equations, we find C₁ = 1 and C₂ = 4.

Therefore, the particular solution to the initial value problem is y(x) = e^(5x)(cos(5x) + 4sin(5x)).

The other two angle measures of a right triangle with side lengths 5, 12, and 13 can be found using trigonometric ratios. Let's label the sides of the triangle as follows:

- The side opposite the angle we are looking for is 5.
- The side adjacent to the angle we are looking for is 12.
- The hypotenuse is 13.

To find the first angle, we will use the inverse tangent function (tan^(-1)). The formula is:
Angle = tan^(-1)(opposite/adjacent)

Plugging in the values, we get:
Angle = tan^(-1)(5/12)

Using a calculator, we find this angle to be approximately 22.6 degrees (rounded to the nearest degree).

To find the second angle, we will use the fact that the sum of the angles in a triangle is 180 degrees. Therefore, the second angle can be found by subtracting the right angle (90 degrees) and the first angle from 180 degrees.
Second angle = 180 - 90 - 22.6

Calculating this, we find the second angle to be approximately 67.4 degrees (rounded to the nearest degree).

Therefore, the other two angle measures of the right triangle are approximately 23 degrees and 67 degrees.
