Answer:
a = 1 and b = - 10
Step-by-step explanation:
Expand the right side of the identity
x(ax² - 3x + b) - 3(ax² - 3x + b)
= ax³ - 3x² + bx - 3ax² + 9x - 3b
= ax³ - x²(3 + 3a) + x(b + 9) - 3b
Equate the coefficients of like terms on both sides of the identity
x³ terms → ax³ with x³ ⇒ a = 1
x terms → - x with (b + 9)x ⇒ b + 9 = - 1 ⇒ b = - 10
Answer:
C
Step-by-step explanation:
-x is the reflection and +1 is the translation
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.
