Well I’m getting 574.5 for the first one and not getting the same for any of them.
By the equations according to the <em>cylindrical</em> system of coordinates, the equation for a helix are x = 8 · cos (2π · t /T), y = 8 · sin (2π · t /T) and z = 6 · (t/T).
<h3>How to derive the equations of a helix in cylindrical form</h3>
According to the <em>cylindrical</em> system of coordinates, helix can be described by the following equations:
Radius
x = r · cos (2π · t /T) (1)
y = r · sin (2π · t /T) (2)
Height
z = H · (t/T) (3)
Where T is the period of one <em>complete</em> revolution.
If we know that r = 8 and H = 6, then the equations for the helix is:
x = 8 · cos (2π · t /T)
y = 8 · sin (2π · t /T)
z = 6 · (t/T)

Answer:
$426
Step-by-step explanation:
According to the question,
New car cost = $20,448
Time to repay = 4 years or 48 months
So, we can calculate the monthly car payment by using following formula,
Monthly car payment = New car cost ÷ Time to repay
By putting the value, we get
Monthly car payment = $20,448 ÷ 48
= $426
Hence, Alex monthly car payment is $426.
We would convert the gallons to cup hence 1 gallon is equal to 16 cups = gallons
