A scientist has four petri dishes of different sizes. Each dish contains a different number of bacteria.
A 3-column table has 4 rows. The first column has entries Dish A, Dish B, Dish C, Dish D. The second column is labeled Population of Bacteria with entries 7,200, 10,000, 13,650, 21,350. The third column is labeled Area (millimeters squared) with entries 2,826, 7,850, 20,096, 31,400.
Find each population density, to the nearest hundredth. Which statement is true?
Dish A has the lowest population density.
Dish C has the greatest population density.
Dish A and Dish B have approximately the same population density.
Dish C and Dish D have approximately the same population density.

(a) compute the maclaurin polynomial m2(x) for f(x) = cos x. (b) use the polynomial of part (a) to estimate cos π 12. (c) use a calculator to compute the error made using the estimate from part (b) for the value of cos π 12. remember that the error is defined to be the absolute value of the difference between the true value and the estimate.

Agroup of students want to create a garden. they do not know the exact measurements but they propose using a variable to represent the length and width of the garden. the length of the garden is 10 feet longer than double the width. use a single variable to write algebraic expressions for both the length and width of the garden. write an algebraic expression for the area of the garden. use mathematical terms to describe this expression.
