Nitrogen-13 is a radioactive isotope of nitrogen used in a physiological test called positron emission tomograph (PET). A typical PET
scan begins with 6.9 picograms of nitrogen-13 (1 picogram grams).
The number N of picograms of nitrogen-13 remaining after t minutes can be
modeled by N = 6.9e-0.06951. How many picograms of nitrogen-13 remain after
10 minutes?

Which segments are congruent? o jn and ln o jn and nm o in and nk onk and nm

Simplify the expression. -2/5(10+15m-20n)

Item 1 which question could the expression 1000n answer? let n = the number of gallons of gas used. how many miles per gallon did the car get driving 1000 miles? let n = the number of grams of food needed for each dog. how many grams of food are needed to feed 1000 dogs? let n = the number of people at the show. how many empty seats were there at the show if there are 1000 seats at the theater? let n = the number of seats at the theater. how many empty seats will there by if 1000 people come to the show?
