3. consider an isosceles triangle a with base 10 and height 12. consider another triangle b formed using vertices which are the center of the sides of triangle a. consider another triangle c whose vertices are similarly formed from b. repeat this process ad infinitum. express the sum of the areas of all such triangles using a series and its closed form sum. compute the areas (a) by using only the first two terms of the series and (b) by using the closed form of the series sum

Answer asap ill give ! ’ a sample of radioactive material decays over time. the number of grams, y , of the material remaining x days after the sample is discovered is given by the equation y = 10(0.5)^x. what does the number 10 represents in the equation? a. the half-life of the radioactive material, in days b. the amount of the sample, in grams, that decays each day c. the time, in days, it will take for the samples to decay completely d. the size of the sample, in grams, at the time the material was discovered

Yo need asap pls ! markin da brainiest too !
