Answer:
f (x) = x2 shows us that function " f " takes " x " and squares it. Example: with f (x) = x2: becomes an output of 16. In fact we can write f (4) = 16. The "x" is Just a Place-Holder! Don't get too concerned about "x", it is just there to show us where the input goes and what happens to it.
Answer:
What is the question? there is only statement.
The answer is C, as both numbers are only both divisible by 1.
Answer: a) extension = 0.12m, b) work done = 2.16 J
Step-by-step explanation: according to hooke's law, provided that elastic limit is kept constant force (f) is proportional to extension (e).
F = ke, k = F / e.
F1/e1 = F2/e2
F1 = 15 N, e1 = 0.10m, F2= 18 N, e2 =?
15/0.10 = 18/e2
e2 = 18 * 0.10/ 15
e2 = 1.8/15
e2 = 0.12m.
Work done at this extension = F2 * e2
Work done = 18 * 0.12 = 2.16 J
