Answer and Step-by-step explanation: Spherical coordinate describes a location of a point in space: one distance (ρ) and two angles (Ф,θ).To transform cartesian coordinates into spherical coordinates:
For angle θ:
- If x > 0 and y > 0:
;
- If x < 0:
; - If x > 0 and y < 0:
;
Calculating:
a) (4,2,-4)
= 6
For θ, choose 1st option:
b) (0,8,15)
= 17
The angle θ gives a tangent that doesn't exist. Analysing table of sine, cosine and tangent: θ = 
c) (√2,1,1)
= 2
= 
d) (−2√3,−2,3)
= 5
Since x < 0, use 2nd option:
Cilindrical coordinate describes a 3 dimension space: 2 distances (r and z) and 1 angle (θ). To express cartesian coordinates into cilindrical:
Angle θ is the same as spherical coordinate;
z = z
Calculating:
a) (4,2,-4)
= 
z = -4
b) (0, 8, 15)
= 8
z = 15
c) (√2,1,1)
= 
z = 1
d) (−2√3,−2,3)
= 4
z = 3
The correct answer is y=4x-1
So, this problem is asking us to find the value of our variable
u.
How can you do this? By isolating the variable, or having only it on one side of the equals sign.
Here's the step by step approach. It's just simple algebra and reverse order of operation (which is what you should do whenever you are solving for a variable).
Multiply both sides by 11 to get rid of the 11 denominator.
Then, subtract both sides by 88 to get u by itself.
Therefore, u is equal to 99.
Answer:
I do believe that the answer would be 56%
Step-by-step explanation:
Using estimation if the box is half full it would have 4.5 books in the box, if you add that extra book it would be around 56%
Answer:
C. 1/2 divided by 13
Step-by-step explanation:
You have to divide the 1/2 gallon between the 13 people...not the 13 people by the 1/2 gallon! Can you mark brainliest again??
