Step-by-step explanation:

The minutes cancel out leaving you with:

= 3.2 revs per second.
The wheel does
3.2 revolutions per second.
Step-by-step explanation:
sec⁴A + tan⁴A = 1 + (2tan²A/cos²A)
LHS = sec⁴A + tan⁴A
= (sec²A)² + (tan²A)² {using formula of a²+b²)
= (sec²A-tan²A) + 2tan²A.sec²A
= 1 + {2tan²A.(1/cos²A)}
= 1 + (2tan²A/cos²A)
Answer:
x=1 2/3y-1/3z hope this helps!
Step-by-step explanation:
5y=3x+z
-z -z
5y-z=3x
/3 /3
1 2/3 - 1/3z=x
x=1 2/3y-1/3z
