With algebra 1. what is (f+g)(x)? f(x)=x^2-36 g(x)=x^3+2x^2-10 2. what is (f•g)(x)? f(x)=x^4-9 g(x)=x^3+9 3. what is (f-g)(x)? f(x)=x^3-2x^2+12x-6 g(x)=4x^2-6x+4

Marcus and cody both leave the park at the same time, but in opposite directions. if cody travels 6 mph faster than marcus and after 4 hours they are 64 miles apart, how fast is each traveling? solve using rare times time = distance.

Suppose a laboratory has a 30 g sample of polonium-210. the half-life of polonium-210 is about 138 days how many half-lives of polonium-210 occur in 1104 days? how much polonium is in the sample 1104 days later? 9; 0.06 g 8; 0.12 g 8; 2,070 g
