Write the equation in spherical coordinates. (a) x2 y2 z2 = 64
vekshin1

The equation in spherical coordinates will be a constant, as we are describing a spherical shell.

r(φ, θ) = 8 units.

<h3>How to rewrite the equation in spherical coordinates?</h3>

The equation:

x^2 + y^2 + z^2 = R^2

Defines a sphere of radius R.

Then the equation:

x^2 + y^2 + z^2 = 64

Defines a sphere of radius √64 = 8.

Then we will have that the radius is a constant for any given angle, then we can write r, the radius, as a constant function of θ and φ, the equation will be:

r(φ, θ) = 8 units.

Mathius walked ⅜ mile to school. Eva walked ⅖ mile to school. How many more
zalisa [80]

Answer:

132ft

Step-by-step explanation:

Mathius Distance = 3/8 mile

Eva Distance        = 2/5 mile

1 mile = 5,280ft

1. Start by multiplying the mile distance of Mathius to the distance of 1 mile in feet.

5,280ft x 3/8 = 15840ft/8 = 1980ft

2. Do the same thing as number 1 but for Eva's distance now.

5,280ft x 2/5 = 10560ft/5 = 2112ft

3. Subtract Eva's Distance from Mathius' Distance for the answer.

2112ft (Eva) - 1980ft (Mathius) = <em>132ft</em>
