Answer with Step-by-step explanation:
We are given that

when x<9
when 
LHD

=
RHD



Hence, the function is not differentiable at x=9
The quotient of the fraction n³ / (2n - 6) ÷ n³ / (3n - 9) is 2/3
<h3 /><h3>How to solve fraction</h3><h3 />
n³ / (2n - 6) ÷ n³ / (3n - 9)
- multiply by the reciprocal of n³ / (3n - 9)
= n³ / (2n - 6) × 1 / n³ / (3n - 9)
= 2n - 6 / 3n - 9
= 2(n - 3) / 3(n - 3)
= 2/3
Therefore, quotient of the fraction n³ / (2n - 6) ÷ n³ / (3n - 9) is 2/3

Answer:
Step-by-step explanation:
Assuming you meant to type b= -3, you would plug in 5 + -3 + -2 to equal 0. The answer would then be 0.
If b was supposed to be +3, then it would be absolute value of 5 + 3 + -2 to equal 6.
Answer:
1.5 km
Step-by-step explanation:
Length of pool = 25m
no.of lengths. = 60
Total length of he swim s = 25m* 60
= 1500m
You know , 1000m = 1km ,
so,
He swims 1500m/1000m
= 1.5 km
