Chris is creating a triangular-shaped garden. he creates a scale drawing with coordinates a, b, and c to represent each corner of the garden. triangle abc has vertices located at a(4, 0), b(4, 3) and c(–3, 0).

see in the diagram above the triangle that represents chris’s garden. use the formula for the area of a triangle to determine the area of the garden in square units. show your work.

chris knows that 1 unit is equivalent to 2 ft on his graph. chris says that to calculate the area in square feet, he can just double the area that he calculated in square units. is chris correct? explain why or why not.

chris decides to plant corn in one-third of his garden. chris wants to plant only four corn plants in each square foot of this section of the garden to ensure each plant has enough room to grow. how many corn plants will he need? show your work.

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

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.
