Drug Testing The concentration of a drug (in parts per million) in a patient's bloodstream hours after administration of the drug is given by the function P(t) = -t^4+12t^3-9t^2+108t
a. When will the drug be totally eliminated from the bloodstream? Explain.
b. Looking at your graph, estimate the maximum concentration of the drug (since the coefficients of P(x) have been chosen to make the polynomial “nicer” this number will be abnormally high).
P(t)≈ 2400

P(t)≈2500

P(t)≈ 2450

P(t)≈ 2550

c. Again, looking at your graph, estimate the time at which the maximum concentration occurs.
a) t≈9.5
b) t≈8
c) t≈9
d) t≈8.5

d. estimate the amount of time for which the concentration is above 80% of maximum.
a) t=7.5
b) t=7
c) t= 6.5
d) t=6
please help this is due soon im lost and i have no tutoring avilable rn to help me

(i really need ) read the story problem, and then answer the questions that follow. gordon works for a graphic design firm and is creating a label for a food truck vendor. the vendor specializes in finger food and wants to sell food in right conical containers so that they are easy for people to hold. to complete his label, gordon needs to collect several different measurements to ensure that the label he designs will fit the surface of the container. gordon has been told that the containers have a diameter of 4 inches and a height of 6 inches. part a: find the slant height of the cone. the slant height is the distance from the apex, or tip, to the base along the cone’s lateral surface. show your work. part b: find the measure of the angle formed between the base of the cone and a line segment that represents the slant height. part c: imagine two line segments where each represents a slant height of the cone. the segments are on opposite sides of the cone and meet at the apex. find the measurement of the angle formed between the line segments.
