20.18 using the following data, calculate the work done by stretching a spring that has a spring constant of k 300 n/m tox-0.35 m. to do this, first fit the data with a polynomial and then integrate the polynomial numerically to compute the work: f, 103. n , m 0.01 0.05 0 0.028 0.10 0.046 0.15 f, 103.n 0.063 0.082 0.1 0.13 0.35 x, m 0.20 0.25 0.30

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

what? ?

what type of question is thiss

step-by-step explanation:

option c is correct.

step-by-step explanation:

the rule regarding the sides of triangle is:

(length of longest side)^2 = square of sum of other two sides.

the sides given are:

6, 10 and 8.

applying the rule we will get:

(10)^2 = (6)^2 + (8)^2

100 = 36+64

100 = 100

so, her answer is incorrect.

no, she should have added 6^2 and 8^2 and compared that to 10^2.

so, option c is correct.
