Step-by-step explanation:
Answer:
The height of the jumping hill x = 189.3 m
Step-by-step explanation:
From Δ ABC
AB = x = height of the hill
∠A = 36° , ∠B = 90°
Thus ∠C = 180 - ∠A - ∠B
⇒ ∠C = 180 - 36 - 90
⇒ ∠C = 54°
From Δ ABC
x = 0.809 × 234
x = 189.3 m
This is the height of the jumping hill.
1.) (x - 4)(x + 1) = 0
x^2 + x - 4x - 4 = 0
y = x^2 - 3x - 4
2.) (x - 2)(x - 6) = 0
x^2 - 6x - 2x + 12 = 0
x^2 - 8x + 12 = 0
since the function has a maximum point the leading coefficient is negative.
Therefore, required equation is y = -3x^2 + 24x - 36
3.) a(x + 3)^2 = ax^2 + 6ax + 9a
since the y intercept is at y = 18 => 9a = 18 => a = 2
Therefore, required function is y = 2x^2 + 12x + 18
You can stack 77 books into 7 piles of 11, or into 11 piles of 7. So in two different ways.
