Answer:
(2+n)-3
That's how you write if that is what you want.
Alright, so we have tickets for 8 dollars. The number of tickets can represent x, and the money totaled is 8x. x=16+17+13=46, so we can substitute that in to get 8*46 for the total revenue=368 dollars
Answer:
6x + 5y + 13 = 0.
Step-by-step explanation:
y = 5/6x + 7/6
Gradient = 5/6
Since the line is perpendicular to y = 5/6x + 7/6
then its gradient is -6/5.
Hence its equation is: point (-8,7).
y - 7 = -6/5(x -(-8))
multiplying through by 5 we get;
5y - 35 = -6(x + 8)
5y - 35 = -6x - 48
6x + 5y + 13 = 0
E^x = 1 + x + x² / 2 + x³/ 3! + x^4 / 4! + .....
= (1 + x + x²/2 ) + x³ [ 1/6 + x /4! + x² / 5! + .... ]
Error = e^x - (1+ x + x² ) = x³ [ 1/6 + x /4! + x² / 5! + .... ]
x / 4! < x / 6 x² / 5! < x² / 6 and so on
So if we replace all factorials by 1/6 ..
error < x² [ 1/6 + x/6 + x²/6 + ... ]
< x² / 6 [ 1 + x + x² ..... ]
< x² / 6 * 1 / (1 -x) = x² / 6 (1-x) if x < 1
maximum error = x² /6(1-x) occurs at 0.4 or -0.4 in the given interval.
= 0.0444444
All that you're basically doing is plugging in the equations to how they ask you to solve
