The slope of the linear function that represents the cost of plan B is $0.17.

In Mathematics, the slope of any straight line can be determined by using this mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = rise/run

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Since Plan B has the same monthly base charge as plan A, we can logically deduce that the data points (0, 14.45) and (45, 22.10) lie on the linear function.

Substituting the given data points into the slope formula, we have the following;

Step-by-step explanation:

m = 532 - (57 * h) represents the number of miles remaining after h hours of traveling at an average speed of 57 miles per hour.

The equation m = 532 - (57 * h) is used to represent the number of miles remaining, m, after h hours of traveling at an average speed of 57 miles per hour. The equation works by taking the total distance, 532 miles, and subtracting the product of the average speed, 57 miles per hour, and the amount of hours traveled, h. The result of the equation is the number of miles remaining, m. For example, if the family has been traveling for four hours, the equation would be m = 532 - (57 * 4). Solving the equation, m = 344, meaning the family has 344 miles left to travel. This equation allows the family to easily determine how many miles they have left to travel, given the average speed and amount of time traveled.

The distance the plane traveled from point A with measures an angle of elevation of 16°, to point B with measures an angle of elevation of 28°, is equals to the 11,728.6feet.

Jaya spots an airplane on radar that is currently approaching in a straight line start from point O in above figure, and that will fly directly overhead.

Altitude that plane maintain,h = 7300 feet

Initially, measure an angle of elevation to the plane at point A = 16°

Measure an angle of elevation to the plane at point B = 28°

Now, Let the distance between point A and point B be equal to 'x feet' and distance between point B and point C ( base) be equal to 'y feet'. So, distance between point A to point C = (x + y ) feet. We have to calculate the distance the plane traveled from point A to point B, i.e., x feet. See the above figure carefully, we see in right angled triangle BOC, tan 28° = 7300/y --(1)

In right angled triangle AOC,

tan 16° = 7300/(x + y) --(2)

Cross multiplication in equation (2)

=> tan 16° ( x + y ) = 7300

=> x + y = 7300/tan 16° --(3)

from equation (1), y = 7300/tan 28°

=> y = 7300/0.5317 = 13,729.55

so, x = 7300/tan 16° - y = 7300/0.287 - 13,729.55

= 25,458.12 - 13,729.55

= 11,728.58 ~ 11,728.6

Hence, required distance is 11,728.6feet.

Step-by-step explanation:

Answer: The area of each slice of pizza can be calculated by finding the area of the whole pizza and dividing it by the number of slices.

The radius of the pizza is half of the diameter, so the radius is 20/2 = 10 inches.

The area of the whole pizza can be calculated using the formula for the area of a circle:

Area = π × radius^2

Area = π × 10^2

Area = 100π square inches

Since there are 8 slices, each slice has an area of:

100π square inches / 8 = 12.5π square inches

Therefore, the area of the 5 slices that Chris ate is:

5 × 12.5π square inches = 62.5π square inches

This is approximately equal to 196.35 square inches, when rounded to two decimal places.

The relationship between the number of times Trevor turns the crank, x, and the height the box has been lifted, y, is a linear equation y = (3/5)x.

What is a linear equation?

A linear equation is an algebraic equation in which each term is either a constant or a product of a constant and a variable raised to the first power (i.e., the variable is not squared or cubed). The general form of a linear equation with one variable, x, is:

ax + b = 0

Now,

We are given that there is a proportional relationship between the number of times Trevor turns the crank, x, and the height the box has been lifted, y. Let k = constant of proportionality.

Then, we can write the equation as:

y = kx

We also know that Trevor turns the crank 5 times to lift a box 3 feet.

Now

3 = k(5)

Solving for k, we get:

k = 3/5

Substituting this value of k in the equation, we get:

y = (3/5)x

Therefore, the equation for the relationship between the number of times Trevor turns the crank, x, and the height the box has been lifted, y, is y = (3/5)x.

Answer:

  f(-3) = 6

Step-by-step explanation:

You want the value of f(-3) given a graph of f(x).

To find the value of f(-3), locate -3 on the x-axis. Follow the vertical grid line to where it intersects the graph of f(x). Follow the horizontal grid line from there to the axis marked f(x), and read the value on the vertical scale.

The attachment shows this process, and that the value of f(-3) is 6.

__

Additional comment

Unless there is information to the contrary, the usual assumption is that each grid line represents one unit. Positive is to the right of the vertical axis, and up from the horizontal axis. Then x=-3 is 3 grid lines left of the vertical axis.

The notation f(x) means the value of function f depends on the value x. The expression f(-3) is the function value when x=-3. Here, it is found by reading the graph. In other situations, it might be found from a table or by evaluating an algebraic expression.

The probability that a customer ordered a hot drink, given that they ordered a small, is approximately 0.045.

A mathematical technique called the Bayes theorem enables us to revise our views or probability regarding an occurrence in light of fresh data or evidence. It has the name of the reverend Thomas Bayes, a statistician and philosopher active in the 18th century. According to the Bayes theorem, the likelihood of an event A given that an event B has already happened is equal to the likelihood of an event B given that an event A has already occurred, multiplied by the prior likelihood of an event A, divided by the previous likelihood of an event B.

The Baye's Theorem is given as:

P(B|A) = P(A|B) × P(B) / P(A)

Here,

P(A) is the probability that a customer ordered a small drink = 0.22.

P(B) is the probability that a customer ordered a hot drink, regardless of whether it was small or medium or large = 0.05.

P(A|B) is the probability that a customer ordered a small drink, given that they ordered a hot drink = 0.2.

Substitute the value we have:

P(B|A) = P(A|B) × P(B) / P(A) = (0.2 × 0.05) / 0.22 ≈ 0.045

Therefore, the probability that a customer ordered a hot drink, given that they ordered a small, is approximately 0.045.

Mila should receive 44.44% of the profit.

An equation is a statement that asserts the equality of two expressions, typically with one or more variables. Equations are used to represent relationships between different quantities, such as the relationship between the length and width of a rectangle or the relationship between the time and distance traveled by an object.

Profit is the financial gain that is earned by a business or an individual after all expenses and costs have been subtracted from revenue or income. It is the difference between the amount earned from sales or services and the costs incurred to produce or provide those goods or services.

In the given question,

Let's begin by determining the amount of money each person invested in the project.

Let Sydney's investment be x.

Roy's investment is twice Sydney's, so Roy invested 2x.

Mila's investment is twice Roy's, so Mila invested 2(2x) = 4x.

Taniya's investment is half of Mila's, so Taniya invested 0.5(4x) = 2x.

The total amount invested is x + 2x + 4x + 2x = 9x.

Now, we need to find the percentage of profit Mila should receive. Since the profit is shared in proportion to the amount invested, Mila should receive a fraction of the profit equal to her investment divided by the total investment.

Mila's share = (Mila's investment) / (Total investment) x (Total profit)

Mila's share = (4x / 9x) x 27000

Mila's share = 12000

So Mila should receive $12,000 of the profit. To find the percentage of profit Mila should receive, we can divide her share by the total profit and multiply by 100:

Percentage of profit Mila should receive = (Mila's share / Total profit) x 100%

Percentage of profit Mila should receive = (12,000 / 27,000) x 100%

Percentage of profit Mila should receive = 44.44%

Therefore, Mila should receive 44.44% of the profit.
