Hey man ill be honest idrk but it is kinda hard to see
Answer:
<em>3/5 of 30 = (3/5)*30</em>
<em>3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/5</em>
<em>3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/5</em>
<em>3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/53/5 of 30 = 18</em>
<em>3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/53/5 of 30 = 18So when the tank is 3/5 full, there are 18 gallons in the tank.</em>
Answer:
$29,900
Growth
22%
Step-by-step explanation:
Initial value is when t = 0
v(0) = 29900(1.22)^0
v(0) = 29900(1)
v(0) = 29900
-------------------------
Growth
because 1.22 is greater than 1
----------------------------
Yearly value change
1.22 - 1 = 0.22
0.22 * 100 = 22
22%
(Assuming that theses are mixed number fractions) the exact form is -97/24, decimal form -4.0416 repeated, and the mixed number is -4 1/24
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
