A pair of parametric equations is given: x = sin2 t and y = cos t

a. Sketch the curve represented by the parametric equations (use the arrows to indicate the direction of the curve as t increases)
b. Find a rectangular-coordinate equation for the curve by eliminating the parameter.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
