The restrictions are:
1) x ≥ 0
2) number of lower bowl seats = 65% * 18500 = 12,025
=> x ≤ 12,025
3) y ≥ 0
4) number of upper bowl seats = 35% * 18500 = 6,475
=> y ≤ 6,475
It is not necessary to state that x + y ≤ 18,500 because it is included in the other restrictions.
Answer:
I'm sorry but where's the picture
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
Answer:
<h2>
(2m-7)(m+3)</h2>
Step-by-step explanation:
hello:
2m² - m - 21
∆ =b²-4ac a=2 and b= -1 and c= -21
∆ =(-1)²-4(2)(-21)=169 = 13²
m1 = (-b+√∆)/2a = (1+13)4 = 14/4 = 7/2
m2 = (-b-√∆)/2a = (1-13)4 = -12/4 = -3
the factorization is : a(m-m1)(m-m2)
2(m-7/2)(m+3) = (2m-7)(m+3)
