Answer:
Approximately (assuming that the height of the base of the hill is the same as that of the observer.)
Step-by-step explanation:
Refer to the diagram attached.
Angles:
Let the length of segment (vertical distance between the base of the tree and the base of the hill) be .
The question is asking for the length of segment . Notice that the length of this segment is .
The length of segment could be represented in two ways:
For example, in right triangle , the length of the side opposite to is segment . The length of that segment is .
.
Rearrange to find an expression for the length of (in ) in terms of :
Similarly, in right triangle :
Equate the right-hand side of these two equations:
Solve for :
Hence, the height of the top of this tree relative to the base of the hill would be .
The answer is 90;
since each variable has a given value, just plug the numbers into the equation.
3(6)5=90
Since there is no <em>d </em>in the equation, don't worry about it:)
A
The end behaviour as x gets larger and positive ( right- hand end )or larger and negative ( left- hand end )is determined by the term of the greatest degree.
For p(x) that is 4, with
• Even degree (8) and positive leading coefficient (4), then
as x → ∞ , p(x) → ∞ and
as x → - ∞ , p(x) → ∞

(0, 2), (5, 5)
The w-intercept is the constant in the equation, so you know immediately that (x, w) = (0, 2) is one point on your graph.
Since the value of x is being multiplied by 3/5, it is convenient to choose an x-value that is a multiple of 5. When x=5, we have ...
w(5) = (3/5)(5) +2 = 3+2 = 5
So, (x, w) = (5, 5) is another point on your graph.
