Quick - an object is dropped from a tower, 159 ft above the ground. the object's height above ground t sec into the fall is s =159−16t^2. a. what is the object's velocity, speed, and acceleration at time t? b. about how long does it take the object to hit the ground? c. what is the object's velocity at the moment of impact?

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
