Ageometric sequence is defined by the explicit formula an = 5(-4)n-1. what is the recursive formula for the nth term of this sequence?

a. an = -5an-1
b. an+1 = 4an
c. an+1 = 5an
d. an = -4an-1

Do u just plot the numbers on the graph like (1,

How many zeros does the function f(x)=4x3-x2+1 have

Acoffee shop orders at most $3,500 worth of coffee and tea. the shop needs to make a profit of at least $1,900 on the order. the possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea: 6c + 13t ≤ 3,500 3.50c + 4t ≥ 1,900 which graph's shaded region represents the possible combinations of coffee and tea for this order?
