There would be 60 questions on the test.
90%=54
1%= 54/90 = 6/10
100%= 6×100/10 =6×10=60
The order is -1.4, -3/5, 1/4, 0.9, and 9/2. So
D is the correct answer
Y>0 because raising a number to a negative power doesn't make it negative
D. y = 9 because it has a complete zero slope while the y-intercept of the equation is 9, so the equation is y = 9.
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.
