(1 point) Let T be a linear transformation from R3 to R3 . Determine whether or not T is one-to-one in each of the following situations: B 1. Suppose T(a)=u, T(b)=v, T(c)=u+v, where a, b,c, u,v are vectors in R3. C 2. Suppose T is an onto function A 3. Suppose T(−1,−1,−3)=u, T(0,−2,3)=v, T(−1,−2,0)=u+v. A. T is not a one-to-one function B. T is a one-to-one function C. There is not enough information to tell

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
