42.5% and the estimation is 43%
Answer:
Step-by-step explanation:
70 = x/4
x = 4 cos 70 = 1.37m
x = 4 cos 80 = 0.69m
The range is ( 0.69m, 1.37m)
As there are only three values in the table, it is a little hard to be certain of the vertex. However, the slope is positive as there is an increase from the x value -2 to the x value -2 to the x value 0. If there is a vertex within this table, it must be a minimum as the y values are increasing. (-4,-1) is not included within the table, so the vertex appears to be a minimum at (-2,-3).
