A section of a water tube ride at an amusement park can be modelled by the function h(t)=−0.002t^4 +0.104t^3 −1.69t^2 +8.5t +9

where t is the time, in seconds, and h is the height, in metres, above the ground. When will the riders be more than 15 m above the ground?

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6

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
