Step-by-step explanation:

since you know that it is a right triangle, you can use pythagorean theorem, which states that A^2+B^2=C^2. so you add the squares of the smaller numbers, then take the square root of that number to get the answer. it is guess and check, but its a good theorem to know.

6^2=36

8^2=64

36+64=100

√(100)=10

The volume of a rectangular prism is given by the formula V = lwh, where l is the length, w is the width, and h is the height. In this case, we have:

V = 5 x 3 x 8

V = 120 cubic inches

The price of the popcorn is not given, so we cannot calculate the price per cubic inch.

The differential of the function, dt, can be represented as: dt = (∂t/∂v) dv + (∂t/∂u) du + (∂t/∂w) dw = (6v^5 + uw) dv + (vw) du + (uv) dw, Therefore, the differential of the function t = v6 + uvw is (6v5 + uw) dv + uv dw.

To find the differential of the function t = v6 + uvw, we can use the rules of calculus.

First, we can take the derivative of each term separately. The derivative of v6 is 6v5, and the derivative of uvw with respect to v is uw.

Then, we can multiply each derivative by the differential of the corresponding variable. So the differential of v is dv, the differential of u is du, and the differential of w is dw.

Putting it all together, we get:

dt = 6v5 dv + uw dv + uv dw + uv dv

Simplifying this expression, we get:

dt = (6v5 + uw) dv + uv dw

Therefore, the differential of the function t = v6 + uvw is (6v5 + uw) dv + uv dw.

To find the differential of the function t = v^6 + uvw with respect to a variable, say x, we'll use partial derivatives.

The partial derivative with respect to v: ∂t/∂v = 6v^5 + uw
The partial derivative with respect to u: ∂t/∂u = vw
The partial derivative with respect to w: ∂t/∂w = uv

The differential of the function, dt, can be represented as:

dt = (∂t/∂v) dv + (∂t/∂u) du + (∂t/∂w) dw = (6v^5 + uw) dv + (vw) du + (uv) dw

Different logs measure different physical properties of the formation that are related to porosity, and the relationship between the log measurement and porosity can be expressed through equations.

The different logs used to obtain porosity and their principles of measurement, quantities measured, and relation to porosity.
There are three main types of logs used to obtain porosity: neutron logs, density logs, and sonic logs.
Neutron logs: These logs measure the hydrogen content in a formation, which is directly related to porosity. The tool emits neutrons that interact with hydrogen atoms, and the resulting gamma rays are measured. The count rate decreases with increasing porosity. The neutron log can be expressed as:
Porosity = (neutron log reading - matrix reading) / (fluid reading - matrix reading)
Density logs: Density logs measure the bulk density of a formation, which can be related to porosity. The tool emits gamma rays that interact with the formation, and the scattered gamma rays are measured. The bulk density decreases with increasing porosity. The density log can be expressed as:
Porosity = (matrix density - bulk density) / (matrix density - fluid density)
Sonic logs: Sonic logs measure the travel time of sound waves through a formation, which can be related to porosity. The tool sends an acoustic wave and measures the time it takes to travel a specific distance. The travel time increases with increasing porosity. The sonic log can be expressed using Wyllie's time-average equation:
Porosity = (sonic log reading - matrix reading) / (fluid reading - matrix reading)
In summary, neutron logs measure hydrogen content, density logs measure bulk density, and sonic logs measure travel time of sound waves. These measurements can be used to calculate porosity using the respective equations provided.

The top right graph could show the arrow's height above the ground over time.

The initial and the final height are both at eye level, which is the reference height, that is, a height of zero.

This means that the beginning and at the end of the graph, it is touching the x-axis, hence either the top right or bottom left graphs are correct.

The trajectory of the arrow is in the format of a concave down parabola, hitting it's maximum height and then coming back down to eye leve.

The total surface area of the prism is 204 cm²

Prism is a three-dimensional solid object in which the two ends are identical. It is the combination of the flat faces, identical bases and equal cross-sections. The faces of the prism are parallelograms or rectangles without the bases.

Given here: A prism with triangular base with three of its faces as rectangle and its bases triangles.

Thus total surface area is the sum of areas of all these 5 faces

TSA= Sum of the area of the two slanted rectangles + Sum of the two bases + the sum of the rectangle the prism is resting on in the figure

Now dimensions of the slanted rectangles are given by length =12 and breadth =5 and the dimensions of the last rectangle are length =12 and breadth = 6

∴ TSA= 2×12×5 +1/2 ×6×4 +12×6

The total surface area of the television is 21,584 square centimeters.

To find the total surface area of the television, we need to calculate the area of all six sides and add them up.

The front and back sides have the same dimensions and area, so we can find the area of one and multiply it by two. The same goes for the left and right sides.

The area of the front/back sides is:

120 cm x 68 cm = 8160 sq cm

Multiplying by 2 gives us the total area of both front/back sides:

2 x 8160 sq cm = 16,320 sq cm

The area of the left/right sides is:

68 cm x 14 cm = 952 sq cm

Multiplying by 2 gives us the total area of both left/right sides:

2 x 952 sq cm = 1904 sq cm

The area of the top and bottom sides is:

120 cm x 14 cm = 1680 sq cm

Multiplying by 2 gives us the total area of both top/bottom sides:

2 x 1680 sq cm = 3360 sq cm

Adding up all six sides, we get:

16,320 sq cm + 1904 sq cm + 3360 sq cm = 21,584 sq cm

Therefore, the total surface area of the television is 21,584 square centimeters.

According to the Empirical rule,

Mean = 40 inches(given)

Standard deviation = 5 inches(given)

To find out the lower and upper boundaries for the middle of 68% heights-

lower boundary = mean - standard deviation

upper boundary = mean + standard deviation

The slope of the line tangent to the surface z+x^2+y^2-4=0 and parallel to the xz-plane is 2.  This problem would show a surface with a tangent line passing through the point (1, 1, 1) and parallel to the xz-plane.

The slope of the line tangent to the surface z + x^2 + y^2 - A = 0 and parallel to the xz-plane can be determined by taking the partial derivative of the surface equation with respect to y.

Since the line is parallel to the xz-plane, the derivative with respect to y will be zero.

Taking the partial derivative of the equation with respect to y, we have:

∂(z + x^2 + y^2 - A)/∂y = 2y

Since the line is parallel to the xz-plane, the slope of the line will be the same as the partial derivative with respect to y evaluated at the given point (1, 1, 1). Substituting the values into the derivative equation, we have:

Slope = 2(1) = 2

Therefore, the slope of the line tangent to the surface and parallel to the xz-plane that passes through (1, 1, 1) is 2.
