Step-by-step explanation:
Answer:
71° F
Step-by-step explanation:
Consider the rational part of f(t)
( divide numerator and denominator by t³
=
As t → infinity then → 0 , the expression simplifies to
= = 40
Thus after driving for a long time
f(t) = 31 + 40 = 71° F
Answer:
D-y=-3x+5
Step-by-step explanation:
Slope is -3x and y intercept is positive 5
The formula for simple interest for months is I=P * (r / m) * n. Where P is the principle and r is rate and m is the year or 12 months and n equals how many months.
I=300 * (0.068 / 12) * 6 = 10.2
So the interest would be $10.2
120/2 = x/5....120 miles to 2 hrs = x miles to 5 hrs
cross multiply
(2)(x) = (120)(5)
2x = 600
x = 600/2
x = 300....the motorcyclist would travel 300 miles in 5 hrs
or u could do it this way..
120/2 = 60 miles per hr
60 * 5 = 300 miles
