<span>given g(x)=9k−4 and </span><span>g passes through the point (7,−2)
substiting g(7) = 9*k - 4 = -2
so 9*k = -2 + 4 = 2
k = 2/9 or 0.22</span>
The length of the mirror is 64.52 cm
<u>Explanation:</u>
Given:
Distance of the person from the mirror = 145cm
Angle of depression = 14°
Angle of elevation = 11°
Vertical dimension of the mirror = ?
For angle of elevation:

For the angle of depression:

Total length of the mirror, AC = AB + BC
= 28.275 + 36.25cm
= 64.52 cm
Therefore, the length of the mirror is 64.52 cm
