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

The first several steps of evaluating (−2) (3 4 7 ) are shown, including the distributive property. (−2) (3 4 7 )  = (−2) ( 3 + 4 7 )  = (−2)(3) + (−2) ( 4 7 )  = (−6) + ( −8 7 ) what is (−2) ( 3 4 7 )

A. plot the data for the functions ƒ(x) and g(x) on a grid. b. identify each function as linear, quadratic, or exponential, and use complete sentences to explain your choices. c. describe what happens to the function values in each function as x increases from left to right. d. at what value(s) of x are the function values equal? if you cannot give exact values for x, give estimates.
