A researcher begins a study with 1,400 mg of a certain radioactive material. The material has a half-life of 1 day, meaning that after 24 hours one half of the atoms in the sample have disintegrated. The amount in the sample after n days is given by the recursive formula A(n)= 1
2•A(n−1). How much of the material will be left in the sample after 7 days?
After 7 days, nothing mg of the material will be left in the sample.
(Simplify your answer.)

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
