Missing information:

The question is incomplete and the complete question is shown in the attached picture.

The parabola has an axis of symmetry x=22, vertex at (22, 2), and opens downward.

Given the focus (22, 3) and directrix y=1, we can determine the following:

a. Axis of symmetry: Since the parabola is vertical (directrix is horizontal), the axis of symmetry will be a vertical line passing through the focus. So, x=22 is the axis of symmetry.

b. Vertex: The vertex is the midpoint between the focus and the directrix. To find the vertex, average the y-coordinates of the focus and the directrix. Vertex = (22, (3+1)/2) = (22, 2).

c. Direction: If the focus is above the directrix, the parabola opens upward. If the focus is below the directrix, the parabola opens downward. In this case, the focus (22, 3) is above the directrix y=1, so the parabola opens downward.

The absolute maximum value is 3 at x=0, and the absolute minimum value is -2 at x=-1.

To find the absolute maximum and minimum values of the function f(x) = 2x³- 2x² - 2x + 3 over the interval (-1, 0], we'll first find the critical points and then evaluate the function at the endpoints of the interval.

1: Find the derivative of f(x) and set it equal to zero. f'(x) = 6x² - 4x - 2

2: Solve the equation f'(x) = 0 for x to find the critical points. 6x² - 4x - 2 = 0

This quadratic equation does not have rational roots, so there are no critical points in the given interval.

3: Evaluate the function at the endpoints of the interval.

f(-1) = 2(-1)³ - 2(-1)² - 2(-1) + 3 = -2 f(0) = 2(0)³ - 2(0)² - 2(0) + 3 = 3

Since there are no critical points in the interval, the absolute maximum and minimum values occur at the endpoints.

Based on these calculations, option 1 gives you the cheaper price per square inch of pizza.

To determine which option will give you a cheaper price per square inch of pizza, you will need to compare the prices of the two options and calculate their respective prices per square inch.

Let's say option 1 is a large pizza with a diameter of 18 inches and costs $20, while option 2 is a medium pizza with a diameter of 14 inches and costs $15.

To calculate the area of each pizza, you need to use the formula for the area of a circle:

A = πr^2

For option 1, the radius is 9 inches (half of the diameter), so the area is:

A = π(9)^2 = 81π square inches

For option 2, the radius is 7 inches (half of the diameter), so the area is:

A = π(7)^2 = 49π square inches

Now you can calculate the price per square inch for each option by dividing the cost by the area:

Option 1:

Price per square inch = $20 / (81π) = $0.078/square inch

Option 2:

Price per square inch = $15 / (49π) = $0.098/square inch

The continuous compound rate of decay of this isotope is approximately 1.41%.

In order to find the continuous compound rate of decay of the radioactive isotope, we can use the formula:

N(t) = N0 * e^(-λt)

Where N(t) is the amount of the isotope present at time t, N0 is the initial amount of the isotope, λ is the continuous decay constant, and t is the time elapsed (in this case, 6 years).

We are given that 91.9% of the isotope is still present after 6 years, so:

0.919 = e^(-λ * 6)

To solve for λ, we can take the natural logarithm of both sides:

ln(0.919) = -6λ

Now, we can solve for the decay constant:

λ = -ln(0.919) / 6 ≈ 0.0141

The probability that the drug lasts less than 220 minutes for a random sample of 10 people is 0.0571, or about 5.71%.

To solve this problem, we need to use the normal distribution formula and the central limit theorem. The formula for the standard normal distribution is:

z = (x - μ) / σ

where z is the z-score, x is the observed value, μ is the mean, and σ is the standard deviation.

In this case, we want to find the probability that the drug lasts less than 220 minutes (3 hours and 40 minutes) for a random sample of 10 people. To do this, we first need to calculate the sample mean and the sample standard deviation.

The sample mean is the same as the population mean, which is 240 minutes:

μ = 240 minutes

The sample standard deviation is given by the formula:

σ = population standard deviation / sqrt(sample size)

σ = 40 minutes / sqrt(10) = 12.65 minutes (rounded to the nearest hundredth)

Now, we can calculate the z-score for a drug duration of 220 minutes:

z = (220 - 240) / 12.65 = -1.58 (rounded to the nearest hundredth)

We can use a standard normal distribution table or a calculator to find the probability that the z-score is less than -1.58. The probability is approximately 0.0571 (rounded to the nearest ten-thousandth).

Therefore, the probability that the drug lasts less than 220 minutes for a random sample of 10 people is 0.0571, or 5.71%.

To get the center of mass of the system with masses m1 = 4, m2 = 8, and m3 = 9 located at points P1 = (-6, -8), P2 = (3, 1), and P3 = (6, 2), the center of mass of the system is approximately (2.57, -0.29).

Center of Mass (x, y) = (Σ (mi * xi) / Σ mi, Σ (mi * yi) / Σ mi)
First, find the sum of the masses: Σ mi = m1 + m2 + m3 = 4 + 8 + 9 = 21
Next, calculate the x and y coordinates of the center of mass: Σ (mi * xi) = (4 * -6) + (8 * 3) + (9 * 6) = -24 + 24 + 54 = 54,
Σ (mi * yi) = (4 * -8) + (8 * 1) + (9 * 2) = -32 + 8 + 18 = -6.
Now divide these sums by the total mass: x-coordinate = 54 / 21 ≈ 2.57, y-coordinate = -6 / 21 ≈ -0.29.

To determine the domain of the function (g o f o g)(x), we need to consider the domains of the functions g(x) and f(x), as well as the composition of these functions.

Let's assume that the domain of g(x) is G and the domain of f(x) is F.

Since (g o f o g)(x) means that we apply the function g to f(x), and then apply g to the result again, we need to ensure that the output of f(x) is a valid input for g(x).

Therefore, the domain of (g o f o g)(x) is the set of all values of x in F such that g(f(x)) is in G, and g(y) is in G for all y in the range of g(f(x)).

In other words, the domain of (g o f o g)(x) is the set of all x in F such that f(x) is in the domain of g, and g(f(x)) is in the domain of g.

The length of the variable x, obtained from the formula for the surface area of a solid about 10.63 inches

What is the surface area of a solid object?

The surface area of a solid object is the area of the outside surface of the  object.

The dimensions of of the open top box with the square corners 2 in by 2 in cut from the corners are;

Length of the box, L = x - 4 inches

Width of the box, W = x - 4 inches

Height of the box, H = 2 inches

The surface area of the box is therefore;

Volume, A = L × W + 2 × L × H + 2 × W × H

Plugging in the expressions for the length, width and height of the box, the surface area = (x - 4) × (x - 4) + 2 × 2 × (x - 4) + 2 × 2 × (x - 4) = 9·x² - 40·x + 16

The surface area of the box, A = 9·x² - 40·x + 16

Second part;

When the surface area = 609 in², we get;

A = 609 = 9·x² - 40·x + 16

9·x² - 40·x + 16 - 609 = 9·x² - 40·x - 593 = 0

The correct option is (a)  270 degree clockwise rotation because they both result in the same final orientation, just in opposite directions.

A 90-degree counter-clockwise rotational  symmetry  is the same as a 270-degree clockwise rotation. This is because rotations are measured in degrees, and a full circle is 360 degrees. Therefore, rotating something 90 degrees counter-clockwise means turning it a quarter of a full circle, while a 270-degree clockwise rotation means turning it three-quarters of a full circle.

To visualize this, imagine a square with its sides parallel to the x and y axes. If we rotate this square 90 degrees counter-clockwise, its sides will now be parallel to the y and negative x axes.

To estimate the mean 30-year fixed mortgage rate for a home loan in the United States using a random sample of 10 recent loans with an average of 6.40% and a population standard deviation of 0.5%, you can compute the 95% and 99% confidence intervals as follows:

1: Identify the sample mean (x), sample size (n), and population standard deviation (σ).

x = 6.40%

n = 10

σ = 0.5%

2: Calculate the standard error (SE) using the formula SE = σ/√n.

SE = 0.5%/√10 ≈ 0.158%

3: Determine the critical z-values for 95% and 99% confidence intervals.

For a 95% confidence interval, z = 1.96 (from the z-table)

For a 99% confidence interval, z = 2.576 (from the z-table)

4: Calculate the margin of error (ME) using the formula ME = z * SE.

For 95% CI,

ME = 1.96 * 0.158% ≈ 0.309%

For 99% CI,

ME = 2.576 * 0.158% ≈ 0.407%

5: Compute the confidence intervals by adding and subtracting the ME from the sample mean.

95% CI:

(6.40% - 0.309%, 6.40% + 0.309%) = (6.091%, 6.709%)
99% CI:

(6.40% - 0.407%, 6.40% + 0.407%) = (5.993%, 6.807%)

A region is bounded by the curves  y = sinπ x ,  y = 4 x − 1 , and the x-axis. determine the area of the region. use the area formula for a triangle to expedite the calculation and show all your work.

To find the area of the region bounded by the curves y = sin(πx), y = 4x - 1, and the x-axis, we need to first find the points of intersection of the curves.

Setting y = sin(πx) and y = 4x - 1 equal to each other, we get:

sin(πx) = 4x - 1

Solving for x is difficult algebraically, so we can use numerical methods or graphing to estimate the solutions. A graph of the two curves shows that they intersect at approximately x = 0.161 and x = 1.239.

Next, we can find the area of the region by breaking it up into two parts: a triangle and a region bounded by the curve y = sin(πx), the x-axis, and the vertical lines x = 0.161 and x = 1.239.

The triangle has base 1.239 - 0.161 = 1.078 and height 4(1.239) - 1 = 3.956. Using the formula for the area of a triangle, we get:

Area of triangle = (1/2) * base * height

= (1/2) * 1.078 * 3.956

= 2.148

To find the area of the region bounded by y = sin(πx), the x-axis, and the vertical lines x = 0.161 and x = 1.239, we can use integration:

∫ from 0.161 to 1.239 of sin(πx) dx = [-cos(πx)/π] from 0.161 to 1.239 = [-cos(π(1.239))/π] - [-cos(π(0.161))/π] = (1/π) * (cos(0.161π) - cos(1.239π))

Using a calculator, we get:

(1/π) * (cos(0.161π) - cos(1.239π)) ≈ 0.696

Therefore, the total area of the region is:

Area = 2.148 + 0.696

= 2.844 (rounded to three decimal places)

So the area of the region bounded by the curves y = sin(πx), y = 4x - 1, and the x-axis is approximately 2.844 square units.

Step 1: Identify the angles A and B in our expression. In this case, A = ∠BAC and B = 30°.

Step 2: Apply the sine addition formula:

sin(∠BAC + 30°) = sin(∠BAC)cos(30°) + cos(∠BAC)sin(30°).

Now you have the expression for sin(∠BAC + 30°). To calculate its value, you will need the values of sin(∠BAC) and cos(∠BAC), which require more information about the triangle.
