A certain chemical reaction occurs most efficiently if the temperature oscillates between a low of 35c and a high of 100c over a 15 minute interval. The temperature is at its lowest point at t = 0. Use window pane graphing to write the equation of a cosine function as temperature with time in hours.

answer: y=0 if that is what u r looking for

1 1/7 hope i

step-by-step explanation:

8/7 = (1 * 7 + 1) / 7 = 1 + 1/7 = 1 1/7

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
