a. A scientific (theory/law) is a well-tested explanation for a wide range of observations or experimental results. b. Describe one way that laws passed by state legislatures differ from scientific laws. c. Suppose the results of one experiment supported a scientists hypothesis. Could the supported hypothesis be called a theory? Why or why not?

Well-tested explanation supported by many observations__________. (a). controlled experiment (b). hypothesis (c). observation (d). theory

Find the limit. Use l’Hospital’s Rule where appropriate. If there is a more elementary method, consider using it. If l’Hospital’s Rule doesn’t apply, explain why. lim x tends to 0 (1+2x)^1/2-(1+4x)^1/2/x
