Let x = time they take working together . Then:-
1/5 + 1/6 = 1/x
Multiply through by 30x:-
6x + 5x = 30
11x = 30
x = 30/11 = 2.73
answer is 2.73 hours to nearest hundredth
Find critical points by setting derivative equal to 0.
Derivative of polynomial is found by multiplying coefficient by exponent, then subtracting 1 from exponent.
f'(x) = 5x^4 - 30x^2 + 9 = 0
This is in quadratic form, use quadratic formula to find x^2
Answer:
0.41791
Step-by-step explanation:
let x be the number written to the thousandth place then,
x times thousands = 417.91
or, x = 417.91/1000
therefore, x = 0.41791
and so
0.41791 thousand = 417.91
There are many ways you can say it,
one of them would be:
