The tangent ratio of ∠A is
we know that
A mapping diagram shows how the elements are paired. Its like a flow chart for a function, showing the input and output values.
The input values are the elements of the domain and the output values are the elements of the range.
In this problem
Input Values (Domain) are
![[-2, 0, 1,5]](https://tex.z-dn.net/?f=%20%5B-2%2C%200%2C%201%2C5%5D%20)
Output Values (Range) are
![[-6, 3,-5,0]](https://tex.z-dn.net/?f=%20%5B-6%2C%203%2C-5%2C0%5D%20)
therefore
the answer is
The correct answer is the second diagram
see the attached figure
Answer:
.4625
Step-by-step explanation:
To find the mean, add up all the numbers, then divide by the number of terms
(0.2 +0.4+ 1+ 0.25) /4
1.85/4
.4625
