Answer:

Step-by-step explanation:
7y⁴ = 7y²(z - 3ax)
Divide both sides by 7y².
y² = z - 3ax
Add 3ax to both sides. Subtract y² from both sides.
3ax = z - y²
Divide both sides by 3a.

Answer:
the time is 1.57 sec and the distance is 49.32mm
Step-by-step explanation:
Given that,
The angle is 180°
Angular velocity is 2rev/sec
The radius is 10mm
we are to find the time and distance traveled at that time
The formula is
θ = at
where t is the time,
a is the angular velocity
θ is angle in radian
so,
θ = 180° × π/180°
θ = π
= 3.14
Hence ,
θ = at
3.14 = 2t
t = 1.57sec
let the distance be xmm

Therefore , the time is 1.57 sec and the distance is 49.32mm
The measure of angle 4 is 121 degrees
