Me i'll mark you ! i've been working on this problem for an hour or so and i really need ! the ordered pairs model an exponential growth function. {(−1,34), (0,51), (1,76.5), (2,114. 75)} what is the function equation? enter your answer in the box. f(x)=

The function equation for the given ordered pairs is f(x) = 51 (1.5)^x

Step-by-step explanation:

The general equation for an exponential function is f(x)=ab^x, where 'a' represents your initial amount, 'b' represents the rate and your 'x' is the independent variable which is most cases is time.  For this problem, you need to use the 'x' and 'y' values from the given points to find the rate of change.  from the points, we see that the x increases by 1 each time and the y increases by a multiple of 1.5, therefor the rate of change (y/x) is 1.5, or the value of 'b'.  The value of y when x=0 is 51, so that is our initial value, or 'a'.  Plugging in these values into our equation, we get f(x)= 51(1.5)^x.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
