This is the last problem of this packet that is due in 2 weeks because of school me explain and show the work if possible

Franco wants to double the volume of the cone. what should he do?

An equation representing lyle’s hedge-trimming business is a = 12n - 300 where a is the amount of profit or loss in dollars and n is the number of hedges trimmed. how would the graph of lyle’s business change if the equation a = 10n - 300 represented his business? the graph would be flatter. the graph would be steeper. the graph would start closer to the origin. the graph would start lower on the y-axis.

Find the zero function by factoring (try to show work) h(x)=-x^2-6x-9
