The potential energy of the water in a lake is 57 trillion N × m, which is 57 trillion joules (J).

Gravitational potential energy applies in this situation. G P E = m g h is the formula for gravitational potential energy, where: mg stands for weight or mass times gravity (w). The height to which an object can fall before kinetic energy replaces potential energy is denoted by the symbol h. In the example of the lake, we first determine the amount of water using the equation for the volume of a typical cylinder in order to determine the weight of the cylinder: V cy l = π r²L , The weight density of the water per cubic foot, which is about 62 lb, can then be multiplied by this volume: W(water) = (Volume) (Density)

W (water) = (28,000,000 ft² ⋅ 40ft) ( 62 lb ÷ ft³ )

W (water) = 69,440,000,000 lb

To calculate the potential energy, multiply this weight by the height. GPE=mgh

GPE=Wh=(69,440,000,000lb)(600ft)

GPE=41,644,000,000,000ft⋅lb

matching the level of precision by rounding the response to two significant digits. 4.2X10¹³ft⋅lb , or 42 trillion ft-lb.

Because joules are measured in N × m units, multiply the result by fractional equivalencies. 42trillionft × lb × (4.45N ÷ lb) × (m ÷ 3.28ft)

The volume of the resulting solid is 3,280.953 cm3.

The volume of the resulting solid is calculated by subtracting the volume of the inner sphere (the hole) from the volume of the outer sphere (the ball). The volume of a sphere is calculated by the formula V=4/3πr3. Therefore, the volume of the outer sphere is V1=4/3π(13)3=4,714.286 cm3. Similarly, the volume of the inner sphere is V2=4/3π(7)3=1,433.333 cm3. Subtracting V2 from V1 gives the volume of the resulting solid as V3=4,714.286 - 1,433.333=3,280.953 cm3. Therefore, the volume of the resulting solid is 3,280.953 cm3.

The unit kilowatt-hour measures the amount of energy used or produced, whereas the rate at which energy is transformed is measured in kilowatts.

The unit kilowatt-hour (kWh) is a measure of energy, not power. Energy is a measure of the amount of work that can be done, and is usually measured in joules. Power, on the other hand, is a measure of the rate at which energy is transformed, and is usually measured in watts.

A kilowatt-hour is the amount of energy used or produced when a power of one kilowatt is used for one hour. For example, if a 100-watt light bulb is left on for 10 hours, it will have used

100 * 10 = 1000 watt-hours or 1 kilowatt-hour of energy.

So to summarize, the unit kilowatt-hour measures the amount of energy used or produced, whereas the rate at which energy is transformed is measured in kilowatts.

The minimum total cost for the company if all of the order constraints are fulfilled is given as follows:

$25.

The cost function is given as follows:

C = 3x + 2y.

Meaning that:

The relevant restrictions to minimize the costs are given as follows:

Since an item y costs less than an item x, considering the second bullet point above, the cost is minimized with an equal amount of x and y.

From the first restriction, they must have at least 10 amounts, hence the cost is minimized with:

x = 5 and y = 5.

Answer:

2(x+2)² - 18

Step-by-step explanation:

Given

2x² +8x-10

express in the form a(x + b)² + c

Take out common factor 2 from 2x² +8x-10 ==> 2(x² + 4x -5)

x² + 4x - 5 can be converted to the form (x + b)² + c as follows using complete the square technique

(x + b)² = x² +2bx + b²

Comparing  x² +2bx + b² and x² + 4x - 5 we can see that b = 2

So the expression becomes
x² + 4x - 5 = (x+2)³ + c
= x² + 4x + 4 + c

Therefore -5 = 4 - c

c = -5 -4 = -9

Therefore
x² + 4x - 5 = (x+2)³ -9

2(x² + 4x -5) = 2[(x+2)³ -9]

=2(x+2)² -18

ANSWER

Verify

2(x+2)² -18 = 2(x² +4x + 4) - 18 = 2x²+8x +8 - 18 = 2x² + 8x - 10

Step-by-step explanation:

The slope of the situation is 10.20. Answer (a) is correct.

The cost of the breakfast platter of 12 bagels is $10.20 and the cost of a gallon of coffee is $4.65.

The slope represents the rate of change between two variables, typically represented as y and x. In this case, it's not clear which variables we should use to calculate the slope. If we use the number of bagels as x and the cost as y, then the slope would represent the rate of change in cost per bagel.

Alternatively, if we use the gallons of coffee as x and the total cost as y, then we can calculate the slope. The total cost would be the sum of the cost of bagels and the cost of coffee, which is $10.20 + $4.65 = $14.85.

Using the formula for slope, which is (change in y) / (change in x), we can calculate the slope as follows:

slope = (change in cost) / (change in gallons of coffee)

= ($14.85 - $4.65) / (1 - 0)

= $10.20 / 1

= 10.20

Therefore, the slope of the situation is 10.20. Answer (a) is correct.

With his average speed of 3mph, Viktor should leave his house by 6:36 am to arrive at the skaring rink on time.

From the case, we know that:

Average speed = 3.0 mph

Distance = 1.2 miles

Arrival time = 7:00 am

Departure time?

Using the average speed concept, we know that average speed can be calculated by dividing the travel distance with the travel time, or it can be formulated as:

Average speed = distance : travel time

3.0 = 1.2 : travel time

travel time = 0.4 hours

After finding the travel time Viktor spend to go from his house to the skating rink, we need to find the departure time for him to arrieve at the skating rink on time. However, we need to convert the travel time into minutes first.

Travel time = 0.4 hours

Travel time = 0.4 x 60 minutes

Travel time = 24 minutes

Arrival time = Departure time + Travel time

7:00 = Departure time + 24 minutes

Answer:

  (3, 6)

Step-by-step explanation:

You want the coordinates of the orthocenter of triangle WXY with vertices W(2,7), X(3, 4), and Y(6, 7).

The orthocenter is the point where the altitudes of the triangle meet. An altitude is the line through a vertex that is perpendicular to the opposite side.

This is an acute triangle, so the orthocenter is within the boundaries of the triangle.

We note that side WY of the triangle is a horizontal line, so the orthocenter will lie on the vertical line through point X. The x-coordinate of point X is 3, so that vertical line has equation x=3.

Side XY can be seen on the graph to have a slope of 1. Or, you can compute it from the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (7 -4)/(6 -3) = 3/3 = 1

Then the point-slope equation of the altitude to that line will have the opposite reciprocal slope, and will go through point W(2, 7):

  y -7 = -1(x -2)

The y-value of the point of intersection of the altitude through W with the altitude through X will be the solution to ...

Substituting for x in the second equation, we have ...

  y -7 = -3 +2

  y = 6 . . . . . . . . . . add 7

The orthocenter is (x, y) = (3, 6).

The orthocenter of a right triangle is the vertex where the right angle is located. The orthocenter of an obtuse triangle is outside the triangle.

A = (1/3)*20 = 20/3 = 6.7

The function graphed on the paper could be a quadratic function which has the two real roots equal to 3 and 9.

A parabola is a two dimensional figure on a plane which is U shaped and any point on the parabola is at an equal distance from a fixed point called focus and a fixed line called directrix.

The graph of a function is parabola when the function is quadratic.

Quadratic functions are of the form f(x) = ax² + b x + c.

Given that, the parabola touches the x-axis at 3 and 9.

This indicates that roots of the quadratic equation are 3 and 9.

That is, f(x) = 0, when x = 3 and x = 9.

It may be of the form f(x) = (x - 3)(x - 9) = x² - 3x - 9x + 27 = x² - 12x + 27.

A system of 4 linear equations in 3 variables x, y, z can have at most one solution.

It is because a system with more than three equations and only three variables will not have a unique solution due to the fact that the dimension of the solution space of 3-dimensional equations is three, so adding an extra equation will result in an over-determined system.

In other words, there are not enough variables in the system to meet the requirements of all the equations, which leads to an over-determined system where there is either no solution or a unique solution. If the system has exactly two solutions, it means that the solution space of the system of equations has a dimension greater than 3, which contradicts the fact that the dimension of the solution space of a system of 3-dimensional equations is 3.
