The main problems in the constructor are to break the input string apart into terms and to deal with conventions about (shortcuts in) formulas for terms. Think about how we can tell that a point of the String is the beginning of a new term. What missing parts of a term might need to be added in?

Anchors

Step-by-step explanation:

In computer programming such as in Javascript in order to define the start or end of a string, we can use anchors.

Anchors

These are special characters which define the boundary of a string. The caret ^  is used to define the starting point of string while the dollar $ is used to mark the end of string. An anchor has null width

Hence we need to add cater^ to all strings when the constructor divides them

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.

48+y= ?

the y is the variable and the ? could also be a variable
