2. A diver followed a path defined by h(t)=-4.9t? +3t+10 in her dive, where t is the
time, in seconds, and h represents her height above the water, in metres.
a) At what height did the diver start her dive? [1]
b) For how long was the diver in the air? [4]
c) What are the domain and range of the diver while in the air? [4]
d) When will the diver reach a height of 5m? [4]

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

you divide them and then you get the answer i took this class this year
