Step-by-step explanation:
36A) AB = 4/ sin 30° = 4/ 0.5 = 8 cm
36B) AC = 4/ tan 30° = 4/ 0.577 = 6.9 cm
36C) BD = 4/sin 45° = 4/ 0.707 = 5.7 cm
36D) area of ∆ABC = ½×6.9×4= 13.8 cm²
36E) sin A = sin 30° = 0.5
Hi!
- The number in the 10 thousands place is 80,801
- Look to the right of the 8, is the number less than or greater than or equal to 5?
- It is less than 5, so we round down.
80,000
<h2>The answer is 80,000</h2>
Hope this helps! :)

The coefficient of x² is is a negative 0.6, so this function has a maximum value.
the max value of a quadratic function is the value of f(x) when x=-b/2a,
in this case, a=-0.6, b=382
so x=382/1.2=
r(382/1.2)=-0.6(382/1.2)²+382*(382/1.2)
use a calculator: 60801.67 is the number I got.
