When 605,000 is written in scientific notation, what will be the value of the exponent?

The quadratic function h(t)=-16.1t^2+150 choose the graph representation

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?

Write the function for the graph. (1.8) (0,4)
