The equation change of volume of a sphere Rohana uses to solve for this value in cubic feet is V = (4/3)π(10)³ which gives the value 4,188.79 cubic feet.

The formula for the volume of a sphere is given as V = (4/3)πr³, where r is the radius of the sphere and π is a constant value approximately equal to 3.14159.

In this problem, the radius of the sphere is given as 10 feet. So, we can substitute this value into the formula to get the volume of the sphere as:

V = (4/3)π(10)³

Simplifying the right side, we get:

V = (4/3) × π × (1000)

V = (4/3) × 3.14159 × 1000

V = 4.18879 × 1000

V = 4,188.79 cubic feet

Therefore, the volume of the sphere with a radius of 10 feet is 4,188.79 cubic feet.

The volume of the spherical boulder is approximately 71.21 cubic feet.

To find the volume of a spherical boulder, we can use the formula for the volume of a sphere:

V = (4/3)πr³

where V is the volume and r is the radius of the sphere.

We are given that the diameter of the boulder is 10 feet, so the radius is half of that, or:

r = 10/2 = 5 feet

We are also given that the boulder weighs almost 6 tons. To convert this weight to pounds, we can multiply by 2000 (since 1 ton is equal to 2000 pounds):

6 tons * 2000 pounds/ton = 12,000 pounds

The weight of the boulder is related to its volume through its density. The density of a boulder will depend on its composition, but we can make an estimate based on common rock types. For example, granite has a density of about 2.7 grams per cubic centimeter, or 2.7 metric tons per cubic meter (since 1 metric ton is equal to 1000 kilograms). A boulder made of granite would therefore weigh about 2.7 times its volume in cubic meters.

Assuming the boulder is made of granite, we can find its volume by setting its weight equal to its volume times its density:

12,000 pounds = V * 2.7 metric tons/m³

To convert pounds to metric tons, we can divide by 2204.62 (since 1 metric ton is equal to 2204.62 pounds):

12,000 pounds / 2204.62 pounds/metric ton = 5.44 metric tons

Substituting this into the equation above, we get:

5.44 metric tons = V * 2.7 metric tons/m³

Dividing both sides by 2.7, we get:

V = 5.44 metric tons / 2.7 metric tons/m³ = 2.0148 m³

To convert this volume to cubic feet, we can use the conversion factor 1 cubic meter = 35.3147 cubic feet:

V = 2.0148 m³ * 35.3147 ft³/m³ = 71.21 ft³

Therefore, the volume of the spherical boulder is approximately 71.21 cubic feet.

After considering and calculating, the modulus of z is r = [tex]2^{1/32}[/tex] and the argument of z is θ = 5π/32.

To solve this equation, we can first express −1−i in polar form as:

−1−i = √2cis(3π/4)

where cis(θ) = cos(θ) + i sin(θ) is the polar form of a complex number.

Now, we can express z in polar form as:

z = r cis(θ)

where r is the modulus of z and θ is its argument. Substituting this into the equation z¹⁶ = √2cis(3π/4), we get:

r¹⁶ cis(16θ) = √2cis(3π/4)

Taking the modulus of both sides, we get:

r¹⁶ = √2

Taking the argument of both sides, we get:

16θ = 3π/4 + 2kπ or 16θ = -3π/4 + 2kπ

where k is an integer. Solving for θ in the range 0 < θ < 2π, we find that the second smallest positive solution is:

θ = (3π/4 + 2π)/16 = 5π/32

Therefore, the value of z is:

z = r cis(θ) = [tex]\sqrt{2}^{1/16}[/tex] cis(5π/32)

We can simplify this as:

z = [tex]2^{1/32}[/tex]cis(5π/32)

So, the modulus of z is:

r = [tex]2^{1/32}[/tex]

And the argument of z is:

θ = 5π/32

Therefore, the answer is:

z = [tex]2^{1/32}[/tex]  cis(5π/32)

So, the modulus of z is r = [tex]2^{1/32}[/tex] and the argument of z is θ = 5π/32.

The only difference for these devices in 3701 is that the jk-FF (or jk-latch) has an additional control input, which is the clock (CK). The CK input is used to enable and disable the device so that the inputs, j and k, do not always affect the output (Q) of the device.

The SR-FF (or SR-latch) has two inputs, S and R, which directly affect the output, Q. When S=1, the output is set to 1, and when R=1, the output is reset to 0.

On the other hand, the jk-FF (or jk-latch) has three inputs, J, K and CK. When CK is 0, the device is disabled and the outputs remain the same. When CK is 1, the J and K inputs can be used to either set (J=1, K=0) or reset (J=0, K=1) the output, Q.

In summary, the j and k in the jk-FF (or jk-latch) are similar to the s and r in the SR-FF (or SR-latch).

Based on the information provided, the three true statements about Josiah's solution are:

"300 = x." - This statement is true because Josiah predicted that there were 300 rock songs on his MP3 player.

"He did not multiply the numerator and denominator by the correct number to equal 1,500." - This statement is true because in his proportion, Josiah multiplied the numerator and denominator by 30, which is not a multiple of 1,500.

"He should have multiplied the numerator and denominator by 75, not 30, because 20 times 75 = 1,500." - This statement is true because to set up a proportion with 1,500 as the denominator, Josiah should have multiplied the numerator and denominator by a multiple of 1,500. In this case, 75 is a multiple of 1,500, so multiplying by 75 would have been the correct approach.

The perimeter of the square garden is 100 feet.

To find the perimeter of the square garden, first we need to determine the length of one side of the square. The given

information states that the hose, which lies along one diagonal of the garden, has a length of 25√2 feet.

Recall that the diagonal of a square divides it into two congruent right triangles, with the diagonal being the

hypotenuse.

Use the Pythagorean theorem to find the side length of the square. Let 'a' represent the side length of the square.

Then, we have:

a² + a² = (25√2)²

Simplify the equation:

2a² = 625 × 2

Divide both sides by 2:

a² = 625

Find the square root of both sides:

a = 25

Now that we know the side length of the square garden is 25 feet, we can calculate the perimeter.

The perimeter of a square is given by the formula:

Perimeter = 4 × side length

Substitute the side length:

Perimeter = 4 × 25

Angle BAC = 40 degrees

Let's use the trigonometric ratio for the sine of angle BAC:

sin(BAC) = opposite/hypotenuse

sin(40°) = AB/AC

Rearranging the equation to solve for AB, we have:

AB = AC * sin(BAC)

Substituting the given values, we get:

AB = 5 * sin(40°)

Using a calculator to evaluate sin(40°), we find:
