The closest distance up the tree where the wire reaches is 17.93 foot.
<u>Explanation:</u>
Given-
Length of the wire, L = 12 foot
angle, Ф= 48°
Distance upto which the wire reaches the tree, x = ?
We know,
cos Ф = base/ hypotenuse
cos 48° = 12/ x
0.669 = 12/x
x = 17.93 foot
Therefore, the closest distance up the tree where the wire reaches is 17.93 foot.
Answer: No! This is not a function!
Step-by-step explanation:
Functions. Terms. Domain - The set of all inputs of a relation or function. Function - A relation in which each input has only one output. Often denoted f (x). Horizontal Line Test - If every horizontal line you can draw passes through only 1 point, x is a function of y.
Answer:
B
Step-by-step explanation:
In a function the x value cannot repeat
As long as no x value repeats it is considered a function
In answer choice A the x value "1" repeats therefore table a is not a function
In answer choice B no x value repeats twice. This one might be the answer however lets check the other tables just to be safe.
In answer choice C the x value "-4" repeats multiple times therefore table C is not a function
In answer choice D the x value "1" and "2" repeat therefore table D is not a function.
Thus, the answer is B
