Suppose that the demand function for a product is given by D(p)equals=StartFraction 50 comma 000 Over p EndFraction 50,000 p and that the price p is a function of time given by pequals=1.91.9tplus+99, where t is in days. a) Find the demand as a function of time t. b) Find the rate of change of the quantity demanded when tequals=115115 days. a) D(t)equals=nothing (Simplify your answer.)

(a)

(b)

Step-by-step explanation:

The demand function for a product is given by :

Price, p is a function of time given by , where t is in days.

(a)We want to find the demand as a function of time t.

(b)Rate of change of the quantity demanded when t=115 days.

Therefore, when t=115 days

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons
