The height of the balloon from ground is 100√3m.
Justification:
<u>The above situation forms a right angled triangle ABC in which length of cable 200m indicates the hypotenuse side and angle of inclination is 60°</u>.
So, In ΔABC
sinθ = p/h
sin60° = AB/AC
√3/2 = AB/200
AB = 200√3/2
AB = 100√3m.
<u>Note</u>: Figure attached with answer.
Answer:
If n > 0, then n= 1
If n < 0, then n=n
If you could word this a bit differently, I might be able to help more, but this is what I'm getting from it. The way you worded it is a bit confusing.
Answer:
im sorry im just answereing like this to complete challenges but im heping people i understand the problems of.
Step-by-step explanation:
X^4 - 5x^2 - 36 = 0
(x^2 - 9)(x^2 + 4) = 0 - factor the left side
(x + 3)(x - 3)(x^2 + 4) = 0 - factor (x^2 - 9 as difference of squares)
x + 3 = 0 x - 3 = 0 x^2 + 4 = 0 Set each factor to 0 if any 0 the left side 0
x = -3 x = 3 x^2 = -4
x = 2i or -2i
The roots are 3, -3, 2i, -2i (Don't know if you need the imaginary roots but I gave you them anyway)
