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
Answer:
f[g(2)] = 50
Step-by-step explanation:
<u>Given functions:</u>
We are asked to determine f[g(2)], which is known as a composite function. When solving composite functions, you always work inside out.
Step 1: Find the value of g(2) by substituting 2 for x in function g(x).
Step 2: Substitute the found value into the composite function.
![\\\implies f[g(2)]= 2(4+1)^2](https://tex.z-dn.net/?f=%5C%5C%5Cimplies%20f%5Bg%282%29%5D%3D%202%284%2B1%29%5E2)
![\implies f[g(2)] = 2(5)^2 \Rightarrow 2(25) \Rightarrow \boxed{50}](https://tex.z-dn.net/?f=%5Cimplies%20f%5Bg%282%29%5D%20%3D%202%285%29%5E2%20%5CRightarrow%202%2825%29%20%5CRightarrow%20%5Cboxed%7B50%7D)
Hence, the value of the composite function f[g(2)] is 50.
