Okay so i'm in advanced functions and modeling in math in an online class and it's really stressing me out. so if you answer me you will have to be patient so i can learn because i'm not the best at math.
okay so- given: f(x) = x - 7 and h(x) = 2x + 3

write the rule for h(f( i do not know how to do this and i'm in one classroom all day with someone who doesn't know math ?

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
