Step-by-step explanation:
<u>The line of best fit given:</u>
<u>It is given in the slope-intercept form:</u>
- y = mx + b, where m- slope, b - y-intercept
The slope is this situation is m = 0.404 cm and it represents the average growth rate of the plant in one day.
It seems reasonable but without means of control it is difficult to trace the growth while still under the ground, during the first 13-14 days.
Cosine is 
.
Apply the equation:
B is the adjacent side so
cosine is:
Cos(t) = 5/2
Have a great day,
And I hope this helps you!
A postulate is an assumption we use for mathematical reasoning; it isn't yet proven. once it's proven, it becomes a theorem.
Lim x->1 (x^2+8x-2)
substitute x =1
= 1^2 +8(1)-2
= 1 +8 -2
= 7
So the limit = 7
