Answer: x=3 ; y=13

Step-by-step explanation:

1. isolate y from equation to substitute into the second equation

y= 16-x ---> (16-x) = 3x+4

2. move to one side and solve for x

4x=12 --> x=3

3. plug in x value to solve for y

3+y=16 or 3(3)+4

y=13

Step-by-step explanation:

The equation of the parabola that models the flight of the ball is y = ax^2 + 25, where a can be any non-zero real number.

The equation of the parabola that models the flight of the ball can be expressed in the standard form: y = ax^2 + bx + c.

Since the ball is kicked from the origin, the equation simplifies to y = ax^2 + c.

To find the values of a and c, we can use the given information. The ball reaches a maximum height of 25 feet, which means the vertex of the parabola is at the point (0, 25). This gives us c = 25.

Now we need to determine the value of a. Since the maximum height occurs at the vertex, the x-coordinate of the vertex is 0. Additionally, we know that the ball hits the ground 100 feet from where it was kicked. The x-coordinate at that point is 100. Therefore, we can use the vertex form of the parabola equation, which is x = -b/2a, to find a.

Substituting the known values, we have 0 = -b/2a, which implies b = 0. Therefore, a can be any non-zero value.

y = 75x - 450 represents the number of customers served per hour where y is the number of customers served and x is the number of hours.

The point-slope form of a linear equation is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.

To find the equation representing the number of customers served per hour, we can first find the slope of the line by using the information given. The slope of a line is the change in y over the change in x.

In 8 hours, the restaurant serves 600 customers and in 12 hours, 900 customers. Therefore, the change in y is 900 - 600 = 300 and the change in x is 12 - 8 = 4. The slope of the line is 300/4 = 75.

We also know that the restaurant serves 600 customers in 8 hours. This means that when x = 8, y = 600.

Using this information, we can write the equation in point-slope form:

y - 600 = 75(x - 8)

So the equation of the line representing the number of customers served per hour is:

y = 75x - 450

Where y is the number of customers served and x is the number of hours.

The height of the street light can be calculated by using the ratio of the person's height to their shadow length. The street light is 17 feet tall.

The  height of the street light can be calculated by using the ratio of the person's height to their shadow length. In this case, the person is 6 feet tall and their shadow is 8 feet long. This gives us a ratio of 6:8 or 3:4. Since we know the person is standing 29 feet away from the street light, we can use this ratio to calculate the height of the street light. Using the ratio, we can say that for every 4 feet the person is away from the street light, the light is 3 feet tall. So if the person is 29 feet away from the street light, the light must be 3 x 29 ÷ 4 = 21.75 feet tall. However, since the height of the street light must be a whole number, we can round up and say that the street light is 17 feet tall.

The error represented in this scenario is an inappropriate task allocation or a mismatch between job responsibilities and the assigned task during the interview process.

The primary role of a customer service representative is to interact with customers, address their concerns, and log calls professionally and efficiently. In contrast, performing a detailed analysis of call-in data falls under the domain of data analysis or business intelligence roles.

By asking the candidate to perform a task unrelated to their potential job responsibilities, the company may not accurately assess the candidate's aptitude for customer service tasks. This error could lead to selecting a candidate who may excel in data analysis but may not possess the necessary communication and problem-solving skills required for a customer service representative position.

To avoid this error, the company should focus on evaluating candidates based on their skills, experience, and performance in tasks directly relevant to the customer service role.

Answer:

-52 is the 20th term

Step-by-step explanation:

The graph remains at a constant height (y-value) for all x-values within the specified interval. This means that the function does not change in this interval and maintains a consistent output.

If the value of is constant for every value that satisfies a certain condition, it means that the graph is a horizontal line on that interval. The behavior of the graph is constant or unchanging in terms of its vertical position.

When every value of x that satisfies a given condition results in a constant value of y, this tells us that the behavior of the graph of the function on this interval is horizontal. In other words, the graph remains at a constant height (y-value) for all x-values within the specified interval. This means that the function does not change in this interval and maintains a consistent output.

The matching of the tangent and sine angles to their expressions will be:

sin(-π/12) = (✓2 - ✓6)/4

tan(π/12) = 2 - ✓3

tan(5π/12) = 2 + ✓3

1. Sin(-π/12) = sin(-15°)

sin(-15°)  = sin(30° + (- 45°)) = sin(30°)cos(-45°) + cos(30°)sin(-45°)

sin(30°)cos(-45°) + cos(30°)sin(-45°) = 1/2 × (√2)/2 + (√3)/2 × (-√2)/2

1/2 × √2/2 + √3/2 × -√2/2 = (√2)/4 - (√6)/4 = ((√2) - (√6))/4

sin(-15°)  = ((√2) - (√6))/4

= sin(-π/12) = (✓2 - ✓6)/4

2. Tan(π/12) = tan(15°)

tan(15°)  = tan(45° + (-30°)) = (tan(-30°) + tan(45°))/(1 - tan(-30°)×tan(45°))

(tan(-30°) + tan(45°))/(1 - tan(-30°)×tan(45°)) = ((-1/√3) + 1)/(1 - (-1/√3))

((-1/√3) + 1)/(1 - (-1/√3)) = (3 - √3)/(3 + √3) = (3 - √3)·(3 -√3)/((3 - √3)·(3 + √3))

(3 - √3)·(3 -√3/((3 - √3)·(3 + √3)) = (9 - 6·√3 + 3)/(9 - 3) = (12 - 6·√3)/6

(2 - √3)

tan(π/12) = 2 - ✓3

3. Tan(5π / 13) = tan(75°)

tan(75°)  = tan(30° + 45°) = (tan(30°) + tan(45°))/(1 - tan(30°)×tan(45°))

(tan(30°) + tan(45°))/(1 - tan(30°)×tan(45°)) = ((1/√3) + 1)/(1 - 1/√3)

((1/√3) + 1)/(1 - 1/√3) = (3 + √3)/(3 - √3) = (3 + √3)·(3 +√3/((3 - √3)·(3 + √3))

(3 + √3)·(3 +√3/((3 - √3)·(3 + √3)) = (9 + 6·√3 + 3)/(9 - 3) = (12 + 6·√3)/6

(12 + 6·√3)/6 = 2 + √3

Answer:

Logan's swimming average is 2.25 kilometers per hour.

Mila's swimming average swimming speed is 34.44 m/min.

The distance swam by Logan = 750 m

The distance swam by Mila =  of Logan's distance = \(\frac{2}{3}\)  × 750 = 2 × 250 = 500.

This should help. :)

Logan's swimming Average 2.25 kilometers per hour

and Mila's swimming speed is 34.44 m/min.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

The distance swam by Logan = 750 m

Logan's swimming average is 2.25 kilometers per hour.

Mila swam 2/3 of logans distance in 1/4 of an hour

So,

The distance swam by Mila =  2/3 of Logan's distance

= 2/3  × 750

= 2 × 250

= 500.

So, Mila's swimming speed is 34.44 m/min.

Hence, Logan's swimming Average 2.25 kilometers per hour and Mila's swimming speed is 34.44 m/min.

The present value of a future cash flow is the amount of money that would have to be invested today at a given interest rate to produce the future cash flow.

In this case, the interest rate is 2%, and the future cash flows are $1000 in year 1, $1100 in year 2, and $1210 in year 3. The present value of these cash flows is calculated as follows:

Present value = (Future cash flow 1 / (1 + Interest rate)^1) + (Future cash flow 2 / (1 + Interest rate)^2) + (Future cash flow 3 / (1 + Interest rate)^3)
