Function Name: poly Parameters: list of ints, int Returns: int Description: A polynomial of degree n with coefficients a0,a1,a2,a3, . . . ,an is the function p(x) = (a0 * x0) + (a1 * x1) + (a2 * x2) + (a3 ∗ x3) + . . . + (an ∗ xn) This function can be evaluated at different values of x. For example: If p(x) = 1+2x1+ x2, then p(2) = 1+2 ∗ 2+22 = 9. If p(x) = 1+x2+x4, then p(2) = 21 and p(3) = 91. Write a function poly() that takes as input a list of coefficients a0, a1, a2, a3, . . . , an of a polynomial p(x) and a value x. The function will return poly(x), which is the value of the polynomial when evaluated at x.

answer: when the substance contain the two parts (polar and non-polar) like soap.

explanation:

soap is produced from the basic hydrolysis of ester "saponification", it is considered as a salt of hydrocarbons. the soap molecule contains the two parts: a polar group   (-coo-na+) and a non-polar group (r-hydrocarbon part). the polar group is called the head and the tail is the non-polar group. the polar group is hydrophilic in nature (water loving) and the non-polar group is hydrophobic in nature (water repelling).the polar/non-polar nature of a substance is useful that it can dissolve the non-polar substances by the polar part and also can dissolve the polar substances by the non-polar part. it commonly used in detergents and soaps.

Just trying to get some points : p sorry bro
