Answer: Y = -2X + 105
Step-by-step explanation: let speed = x and mpg = y
Using linear equation
Y = MX +c
M = dy/dt = (15 - 25)/( 40 - 45) =
-10/5 = -2
When y = 15 , x = 45
15 = -2(45) + c
15 = -90 + c
C = 105
The model linear equation will be
Y = -2X + 105
Answer:
With currency exchange rates constantly fluctuating it might affect the currency exchange plans of a traveler who plans to spend several thousand dollars as they travel over a period of two months because the traveler may encounter situations where his dollars may not be enough to be exchanged at any decent amount of currency in the country where he/she is in. This poses a serious problem especially if he/she does not have lodging or food ready in that said country.
Step-by-step explanation:
It is rather obvious that we will have to deal with a trigonometric function. Let us see... the first hint is that a function is not defined somewhere. cos and sin are defined for all real numbers... what about tan though? Well, as we approach pi/2, tan becomes larger and larger and it is not defined at pi/2. Given that the tan function has a period of pi (cos and sin have a period of 2pi), this function is the right candidate. Since it is periodic and it is not defined at pi/2, it cannot be defined at any x=pi/2+-npi (if it was defined for some n, then it would have the same value at pi/2 due to periodicity). Hence, a function that works is tanx, or 2*tanx or tanx+6.
