Reasoning write a function y for the lateral area of the hat as a function of the radius of its base, (hint: the formula the lateral cone is y the slant height.) the lateral area of a cone is y=pi radius s where s is the slant height.)

sorry i got nothing

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
