Aball is thrown in the air from the top of a building. its height, in meters above ground, as a function of time, in seconds, is given by

h(t) = −4.9t2 + 12t + 10.

how long does it take to reach maximum height? (round your answer to three decimal places.)

1.225m

Step-by-step explanation:

Maximum height is reached at time t when the derivative of equation is 0

- 9.8t + 12 = 0

-9.8t = -12

Divide through by - 9.8

t = 1.225m to 3 decimal places

answer: this is not a question

step-by-step explanation: this is a answer

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
