How much water will be in each pool when they have the same amount?

The graph that represents the equation is:

The graph shows an upward parabola with vertex (2, -6) and passes through (-1, 7), (0, 0), (4, 0), and (5, 7).

Option B is the correct answer.

We have,

The equation y = (3/2)x² - 6x represents an upward parabola since the coefficient of x² is positive.

Now,

The vertex of the parabola.

x = -b/2a,

where a and b are the coefficients of x² and x, respectively.

So,

a = 3/2 and b = -6

x = -(-6)/(2(3/2)) = 6/3 = 2.

Plugging x = 2 into the equation,

We get y = 3/2(2)² - 6(2) = -6,

so the vertex is (2, -6).

We can eliminate options A and C since their vertices are not (2, -6).

Now,

To check which of the remaining options fits the equation, we can plug in the given points and see if they satisfy the equation.

Option B gives:

When x = -1, y = 3/2(-1)² - 6(-1) = 7

When x = 0, y = 3/2(0)² - 6(0) = 0

When x = 4, y = 3/2(4)² - 6(4) = 0

When x = 5, y = 3/2(5)² - 6(5) = 7.5

So option B fits the equation, and is the graph that represents

y = (3/2)x² - 6x.

Therefore,

The graph that represents the equation is:

The graph shows an upward parabola with vertex (2, -6) and passes through (-1, 7), (0, 0), (4, 0), and (5, 7).

Front-end rounding 10,355 to the nearest ten is 10,360.

Rounding is the process of approximating a number to a specified degree of accuracy or precision. Rounding is useful when we want to simplify numbers or express them in a more manageable or meaningful way. There are various methods of rounding, such as rounding up, rounding down, and rounding to the nearest value.

To round a number to a specified degree of accuracy, we first identify the place value we are rounding to, such as units, tens, hundreds, etc. We then look at the digit in that place value and the digit to the right of it. If the digit to the right is 5 or greater, we round up by adding 1 to the digit in the place value we are rounding, and then replace all the digits to the right with zeros. If the digit to the right is less than 5, we round down by simply dropping all the digits to the right.

To front-end round a number, you look at the digit in the place value you are rounding to and round up or down based on the digit to the right of that place value.

To front-end round 10,355 to the nearest ten, we look at the tens place, which is the second digit from the right. The digit in the tens place is 5, which is greater than or equal to 5, so we round up.

To round up, we add 1 to the digit in the tens place and replace all the digits to the right with zeros. So, rounding up 10,355 to the nearest ten gives us:

The zeros of the function f(x) = (-x - 2)(-2x - 3) are x = -2 and x = -3/2, listed from least to greatest.

Given the function in the question:

f(x) = ( -x - 2 )( -2x - 3 )

To determine the zeros of the function f(x), we need to solve the equation f(x) = 0.

f(x) = ( -x - 2 )( -2x - 3 )

Any point that includes the origin that comes in the shaded region will satisfy the system of equation.

For the points that satisfy the system of inequalities y < x² + 3 and y > x² - 4, we need to graph the two parabolas y = x² + 3 and y = x² - 4 and shade the region where the two graphs overlap.

The graph of y = x² + 3 is an upward-facing parabola that intersects the y-axis at (0, 3). The graph of y = x² - 4 is also an upward-facing parabola that intersects the y-axis at (0, -4).

We can see from the graphs that the region where y < x² + 3 and y > x² - 4 is the shaded region between the two parabolas. This region is bounded by the two lines y = x² + 3 and y = x² - 4.

To find a point that satisfies this system of inequalities, we can pick any point within this shaded region. For example, the point (0, 0) lies within the shaded region and satisfies both inequalities:

[tex]y = 0 < x^2+ 3 = 3\\y = 0 > x^2 - 4 = -4[/tex]

This means that the coordinates of P are (a, b), where a is the value for which f'(a) = 0, and b = f(a).

The term "coordinate" generally refers to a value or set of values that describe the position or location of a point or object in a particular system or space. In mathematics, coordinates are typically used to describe the position of a point on a graph or in a geometric plane, and they usually consist of a set of numerical values that indicate the distance or direction of the point from a specified origin or reference point. In geographic or cartographic contexts, coordinates might refer to latitude and longitude values that indicate a specific location on the Earth's surface. Other systems may use different types of coordinates, but the underlying idea is usually the same: a set of values that describe the position of an object or point in a given space or system.

if the graph of f has a horizontal tangent at point P, this means that the slope of the tangent line at P is zero.

Let (a, b) be the coordinates of P. Then the equation of the tangent line at P is:

[tex]y - b = f'(a)(x - a)[/tex]

Since the slope of the tangent line at P is zero, we have:

f'(a) = 0

This means that the derivative of f at x = a is zero. So, we need to find the value of a for which f'(a) = 0.

Once we find the value of a, we can substitute it into the equation of the tangent line to find the value of b.

So, let's find f'(x) first:

f(x) = ... (the function is not given, so we cannot find f'(x) explicitly)

We know that f'(a) = 0, so we have:

[tex]f'(a) = lim h- > 0 [f(a+h) - f(a)]/h = 0[/tex]

This means that:

[tex]lim h- > 0 [f(a+h) - f(a)]/h = 0[/tex]

Multiplying both sides by h, we get:

[tex]lim h- > 0 [f(a+h) - f(a)] = 0[/tex]

Taking the limit as h approaches 0, we get:

[tex]f(a) - f(a) = 0[/tex]

A linear equation is written in standard form when the coefficients are mutually prime, and the leading coefficient is positive:

  ax +by = c . . . . . . GCF(a, b, c) = 1, a > 0

The equations are easiest to compare when they are all written in standard form.

A system will have an infinite number of solutions when the equations are identical.

A system will have zero solutions when it reduces to ...

  (non-zero constant) = 0

A system will have one solution when the equations are different.

A factor of 2 can be removed from the first equation:

  2x -3y = 5

A factor of 3 can be removed from the second equation:

  2x -3y = 5

These equations are identical, so have infinitely many solutions.

Multiplying the first equation by 2 gives ...

  2y = -3x +6

Adding 3x, we have ...

  3x +2y = 6

When we subtract the second equation from this, we get ...

Okay, let's analyze the linearized data options to determine which equation best models it:

a. log y = 0.116315x+0.249114

This has a positive slope coefficient of 0.116315, so it will model increasing data. But the y-intercept term 0.249114 is negative, so the model line would start below the origin. This does not seem to match the typical linear relationship we would expect.

b. log y = 0.249114x+0.116315

This also has a positive slope coefficient, but now the y-intercept term 0.116315 is positive. This could potentially model increasing data that starts above the origin. However, without seeing the data it's hard to definitively say if this is the best fit.

c. log y = 0.0288761x+0.435269

This has a positive but much smaller slope coefficient of 0.0288761. This would model increasing data at a much shallower rate. Again, without seeing the data we can't rule this out, but it seems less likely.

d. log y = 0.435269x+0.0288761

This has a larger positive slope coefficient of 0.435269, so it would model increasing data at a steeper rate. And the positive y-intercept term of 0.0288761 ensures the model line starts above the origin.

Of these 4 options, choice d (log y = 0.435269x+0.0288761) seems the most likely to best model increasing linear data that starts above the origin. However, without seeing the actual data points, we can't say that with certainty. The slope and intercept values would need to give the closest fit to the data for that to be the definitive choice.

To calculate the gross profit, we need to subtract the cost of goods sold (COGS) from the revenue generated by sales. The revenue generated by sales can be found by multiplying the number of printers sold by the selling price of each printer, which is $1,750.

Revenue generated by sales = 26 x $1,750 = $45,500

The cost of goods sold for each printer is $975, so the total cost of goods sold for all 26 printers is:

Total cost of goods sold = 26 x $975 = $25,350

Therefore, the gross profit can be calculated as:

Gross profit = Revenue generated by sales - Total cost of goods sold

Gross profit = $45,500 - $25,350

Gross profit = $20,150

The gross profit is $20,150.

To calculate the net income, we need to subtract all operating expenses from the gross profit. The operating expenses include your salary ($3,000/month), advertising ($50/month), and office lease ($550/month).

Total operating expenses = $3,000 + $50 + $550

Total operating expenses = $3,600

Therefore, the net income can be calculated as:

Net income = Gross profit - Total operating expenses

Net income = $20,150 - $3,600

Net income = $16,550

The net income is $16,550.

In summary, the gross profit is the revenue generated by sales minus the cost of goods sold, which in this case is $20,150. The net income is the gross profit minus all operating expenses, which in this case is $16,550.
