Give me a second to work on number three. I'll respond ASAP
8*8 = 64
9*9 = 81
so integer part of sqrt 70 is 8 Answer
First make x the subject:-
3x = F(x) + 4
x = (F(x) + 4) / 3
f(-1(x) = (x + 4) / 3 answer
Answer:
=2mπ + π/3 for m ∈ Z.
Step-by-step explanation:
Given the equation 
, we are to find all the values of that satisfies the equation.
General solution for sin is = nπ + (-1)ⁿ ∝, where n ∈ Z.
If n is an even number say 2m, then = (2m)π + ∝ where ∝ = 60° = π/3
Hence, the general solution to the equation will be = 2mπ + π/3 for m ∈ Z.
It will take 8.2 x 10^20 electrons to have the same mass as one dust particle.
To get this answer, we divided the mass of the dust particle by the mass of the electron.
7.5 x 10^-10 divided by 9.1 x 10^-31 is 8.2 x 10^20
