The speed of the van traveling south is 46 miles per hour.

Let the speed of the van traveling south be x miles per hour. Then, the speed of the van traveling north is (x + 10) miles per hour.

Since both vans are moving apart, we add their speeds: x + (x + 10) = 2x + 10 miles per hour.

In 2.5 hours, they are 255 miles apart. So, (2x + 10) * 2.5 = 255.

Now, we solve for x:

5x + 25 = 255
5x = 230
x = 46

To translate one-step equations, you need to understand the language of algebra.

Algebraic expressions involve variables, numbers, and operations such as addition, subtraction, multiplication, and division. One-step equations require only one operation to isolate the variable, making them easy to solve.

To write an equation to represent the statement "15 is 9 more than j," you can use the equation 15 = j + 9. This equation says that 15 is equal to j plus 9. To solve for j, you need to isolate j on one side of the equation by subtracting 9 from both sides. This gives you the equation j = 6.

To solve the equation j % 3 = c, you need to understand the modulus operator, which gives you the remainder when two numbers are divided. In this case, j % 3 means the remainder when j is divided by 3. To solve for j, you need to multiply both sides of the equation by 3, which gives you the equation j = 3c.

In summary, to translate one-step equations, you need to understand the language of algebra and the operations involved. To solve for variables, you need to isolate them on one side of the equation. And to solve equations involving the modulus operator, you need to understand how it works and how to apply it to solve for variables.

The absolute maximum value is 20/17, which occurs at x = 5, and the absolute minimum value is 4/5, which occurs at x = 1.

To find the absolute maximum and minimum values of the function f(x) = 8x/(6x + 4) on the interval (1, 5), we need to find the critical points of the function within the interval and evaluate the function at those points, as well as at the endpoints of the interval.

First, let's find the derivative of the function:

f(x) = 8x/(6x + 4)

f'(x) = [8(6x + 4) - 8x(6)] / (6x + 4)^2

f'(x) = [8(2)] / (6x + 4)^2

f'(x) = 16 / (6x + 4)^2

The critical points occur when f'(x) = 0 or is undefined. However, since f'(x) is always positive on the interval (1, 5), there are no critical points within the interval.

Next, let's evaluate the function at the endpoints of the interval:

f(1) = 8(1)/(6(1) + 4) = 8/10 = 4/5

f(5) = 8(5)/(6(5) + 4) = 40/34 = 20/17

Finally, we need to determine which of these values is the absolute maximum and which is the absolute minimum.

Since f(x) is always positive on the interval (1, 5), the function can never be less than 0. Therefore, the absolute minimum value is the smallest value of f(x) on the interval, which occurs at x = 5, where f(5) = 20/17.

To find the absolute maximum value, we compare the values of f(1), f(5), and the maximum value of f(x) as x approaches the endpoints of the interval. We can use the fact that the function is continuous on the closed interval [1, 5] to find the maximum value.

As x approaches 1, we have:

f(x) = 8x/(6x + 4) → 8/10 = 4/5

As x approaches 5, we have:

f(x) = 8x/(6x + 4) → 40/34 = 20/17

Therefore, the absolute maximum value is 20/17, which occurs at x = 5, and the absolute minimum value is 4/5, which occurs at x = 1.

Determine the solution to the quadratic function graphically.

An object moves in simple harmonic motion with a period of 8 minutes and an amplitude of 12 m. At time =t0 minutes, its displacement d from rest is −12m, and initially, it moves in a positive direction. We can write the final equation for the displacement d as a function of time t: d(t) = 12 * cos((π/4)t + π)

To model the displacement d as a function of time t for an object in simple harmonic motion with a period of 8 minutes and an amplitude of 12m, we'll use the following equation:

d(t) = A * cos(ωt + φ)

where:
- d(t) is the displacement at time t
- A is the amplitude (12m in this case)
- ω is the angular frequency, calculated as (2π / period)
- t is the time in minutes
- φ is the phase angle, which we'll determine based on the initial conditions

Since the period is 8 minutes, we can calculate the angular frequency as follows:
ω = (2π / 8) = (π / 4)

At t = 0 minutes, the displacement is -12m, and the object moves in a positive direction. So we have:
-12 = 12 * cos(φ)

Dividing both sides by 12:
-1 = cos(φ)

Therefore, φ = π (or 180°) since the cosine of π is -1.

The angles on the north side of the intersection are complementary angles because complementary angles are two angles whose measures add up to 90 degrees. At the intersection of Madison Street and Peachtree Street, the north side of the intersection forms a right angle (90 degrees).

Any angle on the north side of the intersection must be complementary to the right angle, meaning its measure must be less than 90 degrees.

For example, if we consider the angle formed by Madison Street and the north side of the intersection, it is less than 90 degrees and therefore complementary to the right angle formed by the intersection. Similarly, if we consider the angle formed by Peachtree Street and the north side of the intersection, it is also less than 90 degrees and complementary to the right angle formed by the intersection.
Therefore, all angles on the north side of the intersection are complementary to the right angle formed by the intersection.

The difference in the proportions of firstborn or only children for the two populations from which these samples were drawn is 0.16.The bound for the error of estimation is 95% confidence that the true difference in proportions of firstborn or only children for the two populations is between 0.058 and 0.262.

To estimate the difference in the proportions of firstborn or only children for the two populations, we can use the sample proportions and apply the formula:

p1 - p2 = (x1/n1) - (x2/n2)

where p1 and p2 are the true population proportions, x1 and x2 are the numbers of firstborn or only children in the samples, and n1 and n2 are the sample sizes.

The sample proportions,

p1 = x1/n1 = 0.7

p2 = x2/n2 = 0.54

Substituting these values into the formula,

p1 - p2 = (x1/n1) - (x2/n2) = 0.7 - 0.54 = 0.16

Therefore, we estimate that the difference in the proportions of firstborn or only children for the two populations is 0.16.

To find a bound for the error of estimation, we can use the formula:

E = z sqrt(p1*(1-p1)/n1 + p2*(1-p2)/n2)

where E is the margin of error, z is the critical value for the desired level of confidence (we'll use z = 1.96 for a 95% confidence interval), and p1 and p2 are the sample proportions.

Substituting the given values, we get:

E = 1.96sqrt(0.7(1-0.7)/180 + 0.54*(1-0.54)/100) ≈ 0.102

The nth partial sum can be written as:

sn = a1 + a2 + a3 + ... + an

= 2(1)^2 - ? + 2(2)^2 - ? + 2(3)^2 - ? + ... + 2n^2 - ?

We can simplify the above expression by factoring out 2 from each term:

sn = 2(1^2 + 2^2 + 3^2 + ... + n^2) - n?

Using the formula for the sum of squares, we have:

sn = 2(n(n+1)(2n+1)/6) - n?

Simplifying further, we get:

sn = (n^3 + 3n^2 + 2n)/3 - n?

Taking the limit as n approaches infinity, we get:

lim n->∞ sn = lim n->∞ [(n^3 + 3n^2 + 2n)/3 - n?]

The first derivative of S is S' = 1/15.
The second derivative of S is S'' = 0.

To find the first derivative (S'):

Starting with the given equation S = 15 + 344 - 1 15, we can simplify it to S = 344 + 15.

We can take the derivative of each term separately since they are added together.

The derivative of a constant (15 and 344) is always 0, so we only need to take the derivative of 1/15.

S' = d/dx (344 + 15)

= d/dx (359)

Answer:

380.1 square kilometers

Step-by-step explanation:

Answer:

We can start by using the vertex form of a quadratic function:

f(x) = a(x - h)^2 + k

where (h, k) is the vertex of the parabola.

We know that the vertex is (59, 300), so we can plug in these values:

f(x) = a(x - 59)^2 + 300

To determine the value of "a", we can use the fact that the parabola passes through the point (119, 0). So we substitute these values for x and y and solve for "a":

0 = a(119 - 59)^2 + 300

-300 = 3600a

a = -1/12

Substituting this value of "a" back into the equation for f(x), we get:

f(x) = (-1/12)(x - 59)^2 + 300

This quadratic function models the path of the flare, with a maximum height of 300 meters at the vertex (59, 300), and landing in the water at the point (119, 0).

The number of unique rhombuses that can be constructed using this information is three.

When given a 40° angle and an 8 cm line segment, we can construct three distinct rhombuses. A rhombus is a quadrilateral with all sides of equal length, and opposite angles are congruent.

In this scenario, the given 40° angle determines the orientation of the rhombus, while the 8 cm line segment determines its side length. By connecting the endpoints of the line segment with congruent opposite angles, we can create three different rhombuses.

Each rhombus formed will possess an angle measure of 40° and a side length of 8 cm. However, these rhombuses will vary in terms of their overall shape and orientation. Each one represents a unique configuration that satisfies the given angle and side length criteria.
