A sample of a radioactive isotope had an initial mass of 350 mg in the year 2009 and decays exponentially over time. A measurement in the year 2015 found that the
sample's mass had decayed to 300 mg. What would be the expected mass of the
sample in the year 2019, to the nearest whole number?

The diameter of a ball is 8 in. what is the volume of the ball? use 3.14 for pi. enter your answer as a decimal in the box. round only your final answer to the nearest hundredth.

In which form is the following function written? y = - 2(x – 3)(x + 5)

Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.
