Answer:
Where are the students answers.
Step-by-step explanation:
BC = a
AC = b
ACB = C
To find the area of such triangle we are going to use the formula;
1/2 * a * b * sine C
Substitute values.
1/2 * 4 * 4 * sine 45
= 5.65^2
Therefore the area of the triangle is 5.65^2
Answer:
x = 6
Step-by-step explanation:
3x - 1 = 17
add 1 to both sides:
3x = 18
divide by 3:
x = 6
(5, 3) is your answer hope this helps!
Answer: A.) It is a linear function because there is a constant rate of change in both the input and output values.
============================================================
Explanation:
Note how x is decreasing by 3 each time
- -2-3 = -5
- -5-3 = -8
- -8-3 = -11
At the same time, y is also decreasing by 3 each time
This means we have a linear function. We have,
slope = (change in y)/(change in x)
slope = (-3)/(-3)
slope = 1
Recall that slope is another term for rate of change, so a constant slope means we have a constant rate of change.
----------------
Another way to find the slope is to pick any two points from the table and use the slope formula
m = (y2 - y1)/(x2 - x1)
You should find that any two points you pick will lead to a slope of 1. I recommend you try out all possible pairs to help convince yourself the slope is 1.
