No answer is possible using only the information given in the question.
In addition to the angle of depression, we need either one of these:
-- the length of the tree's shadow on the ground
-- the slant distance direct from the tip of the shadow to the top of the tree.
I'm going out on a limb and guessing that on the page, next to that much of the
question, was a picture of the tree, with one of these additional items labeled.
There's an important reason why the publisher decided to go to the effort and
expense of printing the picture right there. I leave you to ponder the reason.
Answer:
C
Step-by-step explanation:
Rather than picking, let's try to construct one from the description.
reflected over the x axis means -
the vertex is usually at (0,0), now how do we move a graph? or in other words translating it.
To move left and right you use
where if you subtract h you move right and if you add h you move left. we go from (0,0) to (-4,2). so 0 to -4 is 4 left, so that means we add 4.
To move up and down we use
Here if v is positive you move up and if v is negative you move down. going from (0,0) to (-4,2) it moves up 2
So now we put them all together
And if you look, C matches that exactly.
Answer:
a(n) = 

Step-by-step explanation:
The given expression is in the form of the explicit formula of a geometric sequence.
f(n) = 
Where 'a' = First term of the sequence
r = common ratio
Recursive formula of a geometric sequence is,
a(n) = 
a(n) = 
Where, 
So the recursive formula will be a(n) =
