A fifth-degree polynomial function has a zero at I = -3 with a multiplicity of 2. It also has a zero at I = 2 with a multiplicity of 3. The value of the function is negative when I = -4.
Which graph could model this polynomial function?

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
