Answer:
The diameter of the bacterium is 4.05 times the diameter of the plant cell
Step-by-step explanation:
The given parameters both represent diameters
Plant Cell P = 1.26m
Bacterium B = 5.1m
First write out both expressions:
P = 1.26
B = 5.1
Divide B by P
5.1 / 1.26 = 4.04762 Round to 4.05
Multiply both side by P
P * B/P = 4.05 P
B = 4.05 P
This shows that the diameter of the bacterium is 4.048 times the diameter of the plant cell.
Many students seem puzzled by function notation well after it has been introduced, and ask “why can’t we just write
y = 3x instead of
f(x) = 3x ?”. To motivate the use of function notation and improve understanding, I advocate using multi-variable functions instead of single-variable functions in introducing this notation. My introduction usually proceeds something like this:
Step-by-step explanation:
2*19*50= 1,900 I hope that helps:)
