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.
Just like 2 squared = 4, the square root of 2 multiplied by itself will result in a product of 2. Squaring a number always means multiplying that number by the same number.
C is on the line and D is not on the line.
-1/2(-40)+1=21
-1/2(20)+1≠-11
