f(10)
An exponential function is represented as:

impleies that:
--- (1)
implies that
--- (2)
Divide (2) by (1)



Take 4th root

Substitute
in 


Solve for (a)


f(10) is calculated as:



Answer:
50x105m
Step-by-step explanation:
310 (length of field) - 65-65= 200/4=50
Start with the perimeter subtract 65 twice because the length is on two sides. Now the length and width will be equal so divide by 4. Add 65 back because you subtracted it earlier.
There Are 80 different ways a person can order a two course meal
a) Write an expression to describe the journey of the yellow submarine.
-> ((0 - 40) + 30) - 25
[] Sea level = 0
[] The descend 40 meters = -40
[] After examining the sea, they rose 30 meters = + 30
[] They dove 25 meters to look at an octopus = -25
b) At what depth did they stop to look at the octopus?
-> -35 meters
[] The started at 0 (0), descended 40 (-40), rose 30 (-10), and then sove 25 (-35) to see the octopus
[] Another way to think of this is to simplify our previous expression completely
