Answer:
40 ft
Step-by-step explanation:
The post is 8/12 = 2/3 as tall as the shadow is long. We expect the same relationship holds for the tree.
tree height = (2/3)(shadow length) = (2/3)(60 ft) = 40 ft
The tree is 40 feet tall.
Answer:
$300
Step-by-step explanation:
Front row: $225
Front row = 3 * balcony
225 = 3 * balcony
balcony = $225/3 = $75
One balcony ticket costs $75.
4 balcony seats = 4 * $75 = $300
Answer: $300
X³ + 2x² - x - 2 < 0
x³ - x + 2x² - 2 < 0
x(x² - 1) - 2(x² - 1) < 0
(x - 2)(x² - 1) < 0
(x - 2)(x - 1)(x + 1) < 0
by chacking we get the solution
x ∈ (-∞,-1) ∪ (-1,1)
