Step-by-step explanation:

Given the equation y = 2,5x

y is the height of the water

x is the time.

To get the range of values of the height at t = 60s, we will substitute x = 60 into the function

What is the final elevation if a butterfly starts at 20 m and changes -16 m
Fofino [41]

Answer:

Therefore the final elevation of the butterfly is 4 m.

Step-by-step explanation:

i) initial elevation = 20 m

ii) change in elevation = -16m

iii) therefore final elevation = initial elevation + change in elevation

               =   20 m + (-16 m)  

              =   (20 - 16) m

               =    4 m

Therefore the final elevation of the butterfly is 4 m.
