Step-by-step explanation:

Let's denote the volume of the cube as V and the length of each edge as x. Given that the volume of a cube is V = x^3, we can find the rate at which the length of each edge is changing.

We're given that the rate of change of the volume is dV/dt = 56 in³/sec. We want to find the rate of change of the length of each edge, which is dx/dt, when the length of each edge is 6 inches.

First, we differentiate the volume equation with respect to time t:

V = x^3

dV/dt = d(x^3)/dt

Using the chain rule:

dV/dt = 3x^2 * (dx/dt)

Now, we know that dV/dt = 56 in³/sec and x = 6 in. Plugging these values into the equation, we get:

56 = 3 * (6)^2 * (dx/dt)

Solving for dx/dt:

56 = 108 * (dx/dt)

dx/dt = 56 / 108

dx/dt ≈ 0.5185 in/sec (rounded to four decimal places)

So, the rate at which the length of each edge is changing is approximately 0.5185 inches per second when the edges are 6 inches long.

We can use the Pythagorean theorem to solve this problem. Let's call the distance Brenda is away from the fish "x". Then, we have a right triangle with legs of length 12 and x, and a hypotenuse of length 16. So:

x^2 + 12^2 = 16^2

Simplifying:

x^2 + 144 = 256

x^2 = 112

Taking the square root of both sides:

x ≈ 10.6 feet

Therefore, Brenda is approximately 10.6 feet away from the fish.

Answer: 87.3 inches

Step-by-step explanation: The height of the pyramid is the hypotenuse of a right triangle whose legs are the height and half the length of the base.

Let h be the height of the pyramid, then:

h^2 + (21.6/2)^2 = 88.6^2

h^2 + 233.28 = 7857.96

h^2 = 7624.68

h = 87.3 inches (rounded to one decimal place)

Therefore, the height of the stainless steel patio heater is approximately 87.3 inches.

The volume of the rectangular prism is (867/20) cubic inches.

A volume is just the amount of space taken up by any three-dimensional solid. A cube, a cuboid, a cone, a cylinder, or a sphere are examples of solids. Volumes differ depending on the shape.

To find the volume of a rectangular prism, we need to multiply its length, width, and height. In this case, the length is 10 1/5 inches, the width is 4 1/4 inches, and the height is 2 inches. We can convert the mixed numbers to improper fractions and then multiply:

length = 10 1/5 inches = (51/5) inches

width = 4 1/4 inches = (17/4) inches

height = 2 inches

Volume = length x width x height

= (51/5) inches x (17/4) inches x 2 inches

= (867/20) cubic inches

Therefore, the volume of the rectangular prism is (867/20) cubic inches.

The given quadratic equation is: 10x^2 + 7x + 3 = 0.

To solve this quadratic equation, we can use the quadratic formula:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 10, b = 7, and c = 3.

Substituting these values into the formula, we get:

x = (-7 ± sqrt(7^2 - 4(10)(3))) / 2(10)

x = (-7 ± sqrt(49 - 120)) / 20

x = (-7 ± sqrt(-71)) / 20

Since the square root of a negative number is not a real number, this quadratic equation does not have any real solutions. Therefore, none of the options (A), (B), (C), or (D) are correct.

To convert the expression, Y=x^2-64/16 into the polar form, we would have: r = 2 / √(sin^2θ + cos^2θ).

The polar form of a mathematical expression is a way of representing complex numbers using their magnitude and angle.

For a complex number z = a + bi, where a and b are real numbers, its polar form is given by z = r(cosθ + i sinθ), where r is the magnitude of z and θ is the angle that z makes with the positive real axis.  

So, for the given expression, the polar form can be converted this way:

r^2 sin^2θ = r cos^2θ - 4

r^2(sin^2θ + cos^2θ) = 4

r = 2 / √(sin^2θ + cos^2θ)

Therefore, the polar form is r = 2 / √(sin^2θ + cos^2θ).

To cover a 2000 sq ft wall, we will need 5 gallons of paint.

what is area?

Area is the measure of the size of a two-dimensional surface or region, expressed in square units. It is a fundamental concept in geometry and is used to quantify the amount of space inside a shape, such as a square, rectangle, triangle, or circle. The unit of measurement for area varies depending on the system used, but in the International System of Units (SI), the standard unit of area is the square meter (m²). In everyday life, we often use other units of area such as square feet, square inches, or square centimeters.

To find the conversion factor, we need to divide the number of square feet by the number of square feet covered by one gallon of paint:

Conversion factor = 1 gallon / (400 sq ft/gallon)

So, for a wall that is 2000 sq ft, we can use this conversion factor to find the number of gallons of paint needed:

Number of gallons = (2000 sq ft) / (400 sq ft/gallon) = 5 gallons

To the nearest block, Landon's house is at distance of 12 blocks away from Maria's house if Maria could walk in a straight line.

A basic mathematical theorem relating to the sides of a right-angled triangle is known as Pythagoras' theorem. The square of the length of the hypotenuse, the side that faces the right angle, is said to be equal to the sum of the squares of the lengths of the other two sides, known as the legs, in a right triangle.

This can be written in mathematical notation as:

c² = a² + b²

where c is the length of the hypotenuse, and a and b are the lengths of the legs of the right triangle.

In this case, we can consider the straight line between Maria's house and Landon's house as the hypotenuse of a right triangle, with the distances they walked as the other two sides. We can use the distance formula to find the lengths of those sides:

Distance walked by Maria = √(9² + 3²) = √90 ≈ 9.49 blocks

Distance walked by Landon = √(5² + 7²) = √74 ≈ 8.60 blocks

The correct choice is (4) x² = 34² +29² - 2(34)(29)*cos(56).

Trigonometry is one of the branches of mathematics that deals with the relationship between the sides of a triangle (a right-angled triangle) and its angles. There are six types of trigonometry.

We can use the laws of cosines and sines to solve this problem.

According to the law of cosines, we have:

cos(B) = (a² c² - b²) / 2ac

where a, b and c are the  lengths of opposite sides of angles A, B and C. In this case, we get that a = 34, b = x, and c = 29, and we know that angle C is 56 degrees . Because:

cos(B) = (34² 29² - x²) / (23429)

According to the Law of Sines, we have:

sin(B) / b = sin(C) / c

Substituting the given values ​​we get:

sin(B) / x = sin(56) / 29

Solving Sin(B) we get:

sin(B) = x * sin(56) / 29

Now we can use the identity sin²(B) cos²(B) = 1 to eliminate sin(B) and solve for x:

(x * sin(56) / 29)² cos²(B) = 1

Expanding and substituting  cos(B) from the previous expression, we get:

(x² * sin²(56) / 29²) ((34² 29² - x²) / (2(34)(29))²= 1

Simplifying and solving for x², we get:

x² = 34²+ 29² - 2(34)(29)*cos(56)

Therefore, the correct choice is (4) x² = 34² +29² - 2(34)(29)*cos(56).
