The equation is actually h(t)=-16t^2+1437.  Free fall is always -16t^2 as the position function.  We are looking for how long it takes the object to hit the ground.  In other words, the height of an object is 0 when it is laying on the ground, so how long (t) did it take to get there? We will then set that position equal to 0 and solve for t.  0=-16t^2+1437.  If we subtract 1437 from both sides and divide by -16, we have t^2=89.8125.  Taking the square root of both sides gives us, rounded to the nearest tenth, t = 9.5 or t=-9.5.  The 2 things in math that will never EVER be negative are time and distance/length, so -9.5 is out.  That means that it took just about 9.5 seconds for the object to fall to the ground from a height of 1437 feet when pulled on by the force of gravity.

Answer:

A. $27.23

B. $467.77

Step-by-step explanation:

Lin is shopping for a couch with her dad and heard him ask the salesperson “how much is your commission?” The salesperson says that her commission is 5 1/2% of the selling price. A.How much commission will the salesperson earn by selling a couch for $495?

B.How much money will the store get from the sale of the couch?

Salesperson commission = 5 1/2%

Price of couch = $495

A. Amount earned by the salesperson = 5 1/2% of $495

= 5.5% × 495

= 0.055 × 495

= 27.225

Approximately

Amount earned by the salesperson = $27.23

B.How much money will the store get from the sale of the couch?

Amount the store get = Total price - amount earned by salesperson

= $495 - $27.23

= $467.77
