The population of a local species of dragonfly can be found using an infinite geometric series where a1 = 42 and the common ratio is three fourths. write the sum in sigma notation and calculate the sum that will be the upper limit of this population.

Monica build a remote control toy airplane for science project to test the plane she launched it from the top of a building the plane travel a horizontal distance of 50 feet before landing on the ground a quadratic function which models the height of the plane in feet relative to the ground at a horizontal distance of x feet from the building is shown

An airport in death valley is 60 feet below sea level, and an airplane is flying 2,000 feet above sea level. how many feet must the plane descend in order to land? a. 2060 b. 2000 feet c. 1940 feet d. 1880 feet e.1400 feet will mark as brainliest

Bring the fraction a/a-4 to a denominator of 16-a^2
