a cargo plane is flying at a height of 600 feet when it drop some packages. The height h (in feet) packages can be modelled by h equals -16t^2+600, where t is time (in seconds) since the cargo plane dropped him determine after how many seconds of packages will be 200 feet above the ground by solving the equation for t.

the answer to your question a or b but i am pretty sure it is b. i hope this : )

step-by-step explanation:

answer: i believe the answer is e

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:

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

sale price= $ 475

therefore the price before sale is: $625
