Compare the functions below: f(x) = −3 sin(x − π) + 2
2 answers:
Given:
f(x) = - 3sin(x - π) + 2
h(x) = (x + 7)² - 1
g(x):
x: 0 1 2 3 4 5 6
g(x): 8 3 0 -1 0 3 8
For the range 0 ≤ x ≤ 6,
(a) f(x) takes a minimum value of -3 + 2 = -1, because the minimum value
for the sine function is -1.
(b) g(x) takes a minimum value of -1 according to the given table.
(c) h(x) takes a minimum value of 7^2 - 1 = 48 when x = 0.
A graph of f(x) and g(x) confirms the conclusions.
Answer: Both f(x) and g(x) have minimum values of -1.

Answer:
The tree is 16.25 m tall.
Step-by-step explanation:
Attached is a diagram that better explains the problem.
From the diagram we see that the distance between the top of the tree and the line of sight of the observer is x.
To find the height of the tree, we need to first find x and then add it to the height of the observers line of sight from the ground.
Using SOHCAHTOA trigonometric function:
tan(20) = x/39.2
=> x = 39.2 * tan(20)
x = 39.2 * 0.364
x = 14.27m
Hence, the height of the tree is:
(14.27 + 1.98)m
16.25m
The tree is 16.25 m tall.
