Answer: You need to grap a square where each side has 10 units in the grid.

Step-by-step explanation:

We know that each square has a side lenght of 0.1mm

Each unit in the grid represents 0.01mm

Then 10 units in the grid will represent 10*0.01 mm = 0.1mm.

Then the square face will be writen a square with a lenght of 10 units.

F.8=8f? What is the answer
sveta [45]

Hey there!

f.8=8f

0.8f = 8f

SUBTRACT 8f to BOTH SIDES

0.8f - 8f = 8f - 8f

SIMPLIFY IT!

-7.2f = 0

DIVIDE -7.2 to BOTH SIDES

-7.2f/-7.2 = 0/-7.2

CANCEL out3 -7.2/-7.2 because it give you 1

KEEP: 0/-7.2 because it help solve for the f-value

NEW EQUATION: f = 0/-7.2

SIMPLIFY IT!

f = 0

Therefore, your answer is: f = 0

Good luck on your assignment and enjoy your day!

Change from rectangular to spherical coordinates. (let ≥ 0, 0 ≤ ≤ 2, and 0 ≤ ≤. ) (a) (5, 5 3 , 10 3 )
Nikolay [14]

The spherical coordinate that is converted from the given rectangular coordinate is (12.62, 46.67°, 35.3°).

Here, the given rectangular coordinate is (5, 5.3, 10.3).

Therefore, the value of 'x' is 5, the value of 'y' is 5.3 and the value of 'z' is 10.3.

We can convert the rectangular coordinate (x, y, z) into spherical coordinate (ρ, θ, Φ) by the below mentioned method.

We know, ρ² = (x²+y²+z²)

Therefore, ρ

= √(x²+y²+z²)

= √[(5)²+(5.3)²+(10.3)²]

= √(25+28.09+106.09)

= √(159.18)

= 12.62

Again, tan θ = (y/x)

Therefore, θ = tan⁻¹(y/x) = tan⁻¹(5.3/5) = tan⁻¹(1.06) = 46.67°

Similarly, cos Φ = (z/ρ)

Therefore, Φ = cos⁻¹(z/ρ) = cos⁻¹(10.3/12.62) = cos⁻¹(0.816) = 35.3°

Here, the spherical coordinate is (ρ, θ, Φ).

Therefore, the required spherical coordinate for the given rectangular coordinate is (12.62, 46.67°, 35.3°).
