Answer:
Step-by-step explanation:
((10²-8)+4)×3=288
(10²-8)+4=(100-8)+4=92+4=96
96×3=288
in the like term you can add directly and make it single fraction and in unlike term you have to take LCM of denominator .
The meaning of the horizontal asymptote is that the increase in a person's body temperature is a constant value when long time passes.
You can obtain that value by calculating the limit of the function when t → ∞:
4t
T(t) = ------------- => Lim T(t) when t → +∞ = 0.
t^2 + 1
That means that at long term the Temperature tends to remain at 98.6°F.
You need to work backwards
if it is no more than 9 units away from 8
thus x must be 8-9<x<8+9 solving -1<x<17
so the answer is 4.
