Answer:
Below in bold.
Step-by-step explanation:
b.
If we drop a perpendicular line from B to AC and mark the point D on AC, we have 2 right triangles, with AD = DC = 16 cm.
So tan O = BD/16 = 15/8
BD = (16*15)/8
= 2*15
= 30.
So the area of triangle ABC = 16*30
= 480 cm^2.
Answer:
We have, y=f(x)
From graph, when x = 2, y =f(x)=-5. So, functional value at x=2, f(2) = -5
Answer:
(a) it is less then
(b) it is greater then
Step-by-step explanation:
it those because that the right answer
<span>f(x)=-6x-1
