Answer:
(-1)^n × (n!) × x^-(n+1)
Step-by-step explanation:
I've attached the solution
If 10% was added to the total (100%), then subtract 10% from 17.85.
17.85 * 0.1 = 1.785
17.85 - 1.785 = 16.065
$16.07
Answer:
10x +6y - 14
Step-by-step explanation:
3x - 2y = 13x + 4y = 14
3x = 13x + 6y = 14
-10x = 6y = 14
10x + 6y - 14
Answer:
Find length opposite to 30deg
Opposite = tan(30)*42
= 24.2
Whole side = 24.2+10
Find angle of 0 + 30deg: (say x)
Tan(x) = 33.2/42
Arctan(0.79) = x
x = 38.3
The angle to find:
38.3-30:
8.3
The angle is 8.3deg.
