The function AequalsUpper A 0e Superscript negative 0.01386 x models the amount in pounds of a particular radioactive material stored in a concrete vault, where x is the number of years since the material was put into the vault. If 700 pounds of the material are initially put into the vault, how many pounds will be left after 60 years? Round to nearest whole number.

305 pounds

Step-by-step explanation:

-This is an exponential function given as:

#Where is the initial and final quantities after time x.

#We substitute the given values to solve for A after 60 yrs:

Hence, the amount after 60yrs is 305 pounds

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal
