A weight is attached to a spring suspended vertically from a ceiling. When a driving force is applied to the system, the weight moves vertically from it equilibrium position. This motion is described by the model y = 1.5sin8t - 0.5cos8t where y id the distance from equilibrium in feet and t is the time in seconds. Write the model in the ofrm sqrt(a^2+b^2)sin(Bt+c)

they charge the same amount at 20 minutes.

step-by-step explanation:

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
