Answer:
See below.
Step-by-step explanation:
x^2 + 2 = 3^2/3 + 3^-2/3
x^2 = 3^2/3 + 3^-2/3 - 2
x = √(3^2/3 + 3^-2/3 - 2)
x = 0.748888296
Substitute for x in 3x^3 + 9x - 8:
3( 0.748888296)^3 + 9( 0.748888296) - 8 = 0.
So it is proved.
1 second = 2 megabytes

2 seconds = 4 megabytes
Step-by-step explanation:
Given,
Time taken to download 5 megabytes =
seconds

Multiplying both sides by
to find unit rate

1 second = 2 megabytes




2 seconds = 2*2 megabytes
2 seconds = 4 megabytes
