27. Supply and Demand Suppose that the demand and price for a certain model of a youth wristwatch are related by
where p is the price (in dollars) and q is the quantity demanded (in hundreds). Find the price at each level of demand.
- (a) 0 watches
- (b) 400 watches
- (c) 800 watches
Find the quantity demanded for the watch at each price.
- (d) $8
- (e) $10
- (f) $12
- (g) Graph p = 16 − 1.25q.

- The rate of change of an autocatalytic chemical reaction is kQxkx2 where Q is the amount of the original substance, x is the amount of substance formed, and k is a constant of proportionality. Factor the expression.arrow_forwardThe resistance of a copper wire carrying an electrical current is directly proportional to its length and inversely proportional to its cross-sectional area. A copper wire with a diameter of 0.0126inch has a resistance of 64.9ohms per thousand feet. What length of 0.0201-inch-diameter copper wire will produce a resistance of 33.5ohms?arrow_forwardThe kinetic energy E of an object varies jointly with the object’s mass m and the square of the object’s velocity v . An object with a mass of 50 kilograms traveling at 16 meters per second has a kinetic energy of 6400 joules. What is the kinetic energy of an object with a mass of 70 kilograms traveling at 20 meters per second?arrow_forward
- Heart Disease In a certain country, the number of deaths due to heart disease decreased from 235 in one year to 221 in the next year. What percentage decrease in deaths due to heart disease does this represent?arrow_forwardSolve each problem. y is directly proportional to x. If y=15 when x=4, find y when x=75.arrow_forwardFind the unknown value. 27. y varies jointly with x and the cube root of 2. If when x=2 and z=27,y=12, find y if x=5 and z=8.arrow_forward
