Provide an appropriate response.Derive the equations x = x0 + 
(1 - e-kt)cos ?, y = y0 + 
(1 - e-kt)sin ? + 
(1 - kt - e-kt)by solving the following initial value problem for a vector r in the plane. Differential equation: 
= -gj - kv = -gj - k
Initial
conditions: r(0) = x0i + y0j 
(0) = v0 = (v0cos ?)i + (v0sin ?)jThe drag coefficient k is a positive constant representing resistance due to air density, v0 and ? are the projectile's initial speed and launch angle, and g is the acceleration of gravity.

Solve the problem.The rates of death (in number of deaths per 100,000 population) for 20-24 year olds in the United States between 1985-1993 are given below. (Source: NCHS Data Warehouse) 
A logarithmic equation that models this data is y = 57.76 + 48.56 ln x where x represents the number of years since 1980 and y represents the rate of death in that year. Use this equation to predict the year in which the rate of death for 20-24 year olds first exceeds 200.

Solve the problem. Round rates to the nearest tenth of a percent and dollar amounts to the nearest cent.A jewelry store purchased 80 fashion watches for $2400. If the store sold 40 watches at $60, 32 watches at $54, and the rest at $30, find (a) the total markup, (b) the markup percent on selling price, and (c) the equivalent markup percent on cost.
A. $1968, 45.1%, 82% B. $1968, 82%, 45.1% C. $2400, 55%, 72% D. $4368, 100%, 182%
