Answer:
True
x = 4.32 (2 dp)
Step-by-step explanation:
x³ - 5x = 59
x³ - 5x - 59 = 0
x = 4
4³ - 5(4) - 59 = -15
x = 5
5³ - 5(5) - 59 = +41
A change in sign indicates the existence of root between 4 and 5
Use iterative process to identify the root
x³ - 5x - 59 = 0
x³ = 5x + 59
x = (5x + 59)^⅓
Start at any x between 4 and 5
x(n+1) = (5x(n) + 59)^⅓
x0 = 4.8
x1 = 4.362070671
x2 = 4.323369309
x3 = 4.319915667
x4 = 4.319607202
x5 = 4.318579649
Clearly x is 4.32 (2 dp)
I'm not sure if that's what you mean, but the difference between 6010 and 5060 is 950, so to find a number in a halfway between them I divided 950 by 2 (which is 475) and added it to 5060 (or substracted from 6010 - it's the same). Next I added the same number (475) to 6010. So finally it would like like this:
6,485 ; 6,010 ; 5,535 ; 5,060
3(2n-9) is the equation that is equivalent to 6n-27.
