Constructed Response Task
An object is launched at 144 feet per minute (ft/m) from a 576 feet tall tower. The equation for
the object's heights at timer minutes after launch is
s(t) = -1672 +1441 +576, where s is in feet. When does the object land on the ground
and why?

The object takes 12 minutes to land on the ground.

Explanation:

Given that the equation for the object's height s at time t minutes after the launch is

We need to determine the time that it takes for the object to land on the ground.

Time taken:

The time t of an object can be determined by substituting

Thus, we have,

Switch sides,

Thus, we get,

Let us solve the equation using the quadratic formula.

Thus, the values of t are and

Simplifying, we get,

and

 and

Since, the value of t cannot be negative, then

Thus, the object takes 12 minutes to land on the ground.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
