Answer:

71° F

Step-by-step explanation:

Consider the rational part of f(t)

\frac{40t^3}{t^3+100}  ( divide numerator and denominator by t³

= \frac{40}{1+\frac{100}{t^3} }

As t → infinity then \frac{100}{t^3} → 0 , the expression simplifies to

\frac{40}{1+0} = \frac{40}{1} = 40

Thus after driving for a long time

f(t) = 31 + 40 = 71° F

What are the sine and cosine ratios for a 30°–60°–90° triangle with a hypotenuse of 6, when θ = 60°?
Margaret [11]

Answer:

There are two ways to do this problem algebraically or trigonometrically.

Algebraically/geometrically

The ratios of the sides of a 30/60/90 tri. are x, x√3, 2x (short leg, long leg, hyp). Therefore, if the long leg is 6 'units'. then 6 = x√3. x = 6√3.

The hyp is 2x then the hypotenuse is 2(6√3) = 12√3, rationalizing is 12√3/3 = 4√3

Using Trig.

We can use sinx = y/r = opp/hyp. The long leg of 6 is opposite 60 degrees (pi/3).

Therefore, sin(pi/3) = 6/r =

r = 6/sin(pi/3) = 6/(√3/2) = 12/√3, when you rationalize you get 12√3/3 = 4√3
