The point which has the coordinates (-3.5, 4) is point Z.

Coordinates are the set of points in a geometrical plane or space, which is used to denote the exact point in the coordinate plane or space.

Given coordinate is (-3.5, 4).

This means that the point is at a distance of 3.5 to the left of the origin and at a distance of 4 units above the origin.

So in order to find the point, mark the point -3.5 in the exact middle of -3 and -4 on the X axis.

Mark the point 4 on the Y axis.

Draw perpendicular lines from both.

Intersecting point is the given point.

Here point Z indicates this.

Hence point Z indicates the coordinates (-3.5, 4).

The number of workers required = 15

Observe the given problem and find out the relation between the number of workers and the number of days.

In given two one quantity decreased and the other quantity increased then both quantities are said to be in inverse proportions.    

Here the product of two quantities will equal a constant.

Here we have

10 workers can complete a piece of work in 18 days

Let 'x' be the number of workers required to complete work in 12 days

Here when the number of days increases the number of workers will be decreased which shows the number of work is inversely proportional to the number of days

The relation can be represented as  

=> 10 worker × 18 days  = 12 days × x workers

=> 10 × 18 = 12x

=> x = 180/12

=> x = 15

Therefore,

The number of workers required = 15

Using  Remainder Theorem and synthetic division, f(-10) = 191, f(2) = 1, f(3) = 34

What is synthetic division?

A polynomial's coefficients are split one by one in synthetic division.

The split polynomial's zero, which belongs in the box on the far left, has this value.

To use the Remainder Theorem and synthetic division to evaluate f(-10), f(2), and f(3) for the function[tex]f(x)=2x^2+x^2-10x+1[/tex], we can proceed as follows:

First, we need to perform synthetic division using -10, 2, and 3 as the divisors.

1) For f(-10):

The result of the division is 191, so f(-10) = 191.

2) For f(2):

The result of the division is 1, so f(2) = 1.

3) For f(3):

The result of the division is 34, so f(3) = 34.

Therefore, we have:

f(-10) = 191

f(2) = 1

f(3) = 34

Answer:

Step-by-step explanation:

Let's call the number of large bags of popcorn sold "L" and the number of small bags of popcorn sold "S".

We can set up two equations based on the information given:

L + S = 290 (the total number of bags of popcorn sold)

4L + S = 566 (the total revenue from popcorn sales)

We can use substitution or elimination to solve for L and S.

Substitution:

From the first equation, we know that S = 290 - L. We can substitute this into the second equation:

4L + (290 - L) = 566

Simplifying, we get:

3L + 290 = 566

3L = 276

L = 92

Then we can use the first equation to find S:

L + S = 290

92 + S = 290

S = 198

So the movie theater sold 92 large bags of popcorn and 198 small bags of popcorn.

Elimination:

We can eliminate one variable by multiplying one of the equations by a constant to make the coefficients of one of the variables equal but with opposite signs.

In this case, we can multiply the first equation by 4 to make the coefficients of S equal but with opposite signs:

4L + 4S = 1160

4L + S = 566

Subtracting the second equation from the first, we eliminate L:

3S = 594

S = 198

Then we can use either of the original equations to find L:

L + S = 290

L + 198 = 290

L = 92

So the movie theater sold 92 large bags of popcorn and 198 small bags of popcorn.

This type of study would be a comparative study, as it involves comparing the level of academic motivation between college students and their siblings.

Step-by-step explanation:

It is true that the graph contains the point (0, 0).

The following three assertions regarding the function and its graph are true:

The function's graph resembles a parabola.

The graph begins at the bottom.

The point is shown in the graph (0,0).

Explanation:

A second-degree polynomial function, the quadratic function f(x) = x2 - 5x + 12 has a parabola as its graph.

The parabola widens downward because the coefficient of x2 is positive (1 in this instance).

When we replace x with -10 in the given function, we obtain the value of f(-10) as (-10)2 - 5(-10) + 12 = 82. Hence, "f(-10) = 82" is true.

We substitute x = 20 in the given function, resulting in f(20) = 202 - 5(20) + 12 = 212, to see if the point (20, -8) is on the function's graph. The claim "The graph contains the point (20, -8)" is untrue since the point's y-coordinate is -8, which is not equivalent to f(20).

We substitute x = 0 in the given function to get f(0) = 02 - 5(0) + 12 = 12 to determine if the point (0, 0) is on the function's graph. The assertion "The graph contains the point (0, 0)" is true because the y-coordinate of the point (0, 0) is 0, which is equivalent to f(0).

As the temperature of the pan increases, the heat transfer from the butter to the pan increases, causing the butter to melt faster. Ultimately, this heat transfer is necessary for Luke to prepare his food. Without it, the butter would stay solid and would not cook properly.

Heat transfer is the transfer of energy from one place to another due to a difference in temperature. Heat transfer can occur through conduction, convection, and radiation. Heat is always transferred from hotter to colder objects and the rate of transfer depends on the temperature difference between the two and the material it is passing through. Heat transfer is essential in many natural and man-made processes.

The energy is moving in two directions. Cold is moving from the pan and into the butter, while the heat is moving from the butter and into the pan. This is known as a heat transfer. Heat transfers occur when two objects at different temperatures come into contact with each other. In this case, the cold pan is coming into contact with the warm butter, causing the heat to move from the butter and into the pan. This heat transfer causes the butter to melt. As the temperature of the pan increases, the heat transfer from the butter to the pan increases, causing the butter to melt faster.

We can use the future value formula for an annuity to solve this problem:

FV = PMT * ((1 + r)^n - 1) / r

where:

FV is the future value of the annuity

PMT is the regular payment or deposit

r is the annual interest rate

n is the number of periods (in this case, the number of years)

We want to solve for PMT, so we can rearrange the formula to get:

PMT = FV * r / ((1 + r)^n - 1)

Plugging in the given values, we get:

FV = $80,000

r = 6% = 0.06

n = 15 years

So, the annual deposit required is:

PMT = $80,000 * 0.06 / ((1 + 0.06)^15 - 1) ≈ $3,782.58

Therefore, the man would need to deposit approximately $3,782.58 into the account each year in order to have $80,000 saved up for his granddaughter's college education in 15 years, assuming a 6% return.

If a car travels at an average speed of 68 miles per hour, it takes it 5 hours 15 minutes to travel 357 miles.

The average speed is the unit rate.

The average speed is computed as the quotient of the total distance and the total time.

Conversely, the time is a function of the division of the total distance by the average speed.

The total distance traveled by the car = 357 miles

The average speed = 68 miles per hour (mph)

The time = Distance/Average speed = 357/68 = 5.25 hours

The service's expected profit is $6,800.

What is the basic arithmetic operations?

The four basic mathematical operations are Addition, subtraction, multiplication, and division.

To find the service's expected profit, we need to calculate the total revenue and the total cost, and then subtract the cost from the revenue.

First, let's calculate the total revenue. The service sells maintenance agreements for $75 a year, so for every 100 customers, the revenue will be:

100 customers x $75/customer = $7,500

Now, let's calculate the total cost. We know that 2 in every 100 people who purchase maintenance agreements have air conditioners that need repair, and the average cost of repairing an air conditioner is $350. So for every 100 customers, the cost of repairs will be:

2 customers x $350/customer = $700

Finally, let's calculate the expected profit:

Expected profit = Total revenue - Total cost

Expected profit = $7,500 - $700

Expected profit = $6,800

Hence, the service's expected profit is $6,800.

Answer: We can use the formula for future value of an annuity to calculate how much will be saved for retirement:

FV = Pmt x (((1 + r)^n - 1) / r)

where:

FV is the future value of the annuity

Pmt is the payment made each period (in this case, the annual profit of $22,000)

r is the annual interest rate (9% or 0.09 as a decimal)

n is the number of periods (7 years)

Substituting the given values into the formula, we get:

FV = $22,000 x (((1 + 0.09)^7 - 1) / 0.09)

FV = $22,000 x (1.9904 / 0.09)

FV = $22,000 x 22.116
