Answer: The height is 4.472
Step-by-step explanation: That formula is Heron's formula.
Where "s" is calculated like this:
s = (a + b + c) / 2
In this case:
a = 14
b = 12
c = 6
replacing:
s = (14 + 12 + 6) / 2
s = 16
Now we calculate the area:
A ^ 2 = 16 * (16−14) * (16−12) * (16−6)
A ^ 2 = 1280
A = 35.777
The area of the triangle is:
A = b * h / 2
In this case we will take the base as the longest side of the triangle, that is to say = 14
Thus:
h = A * 2 / b
h = 35.777 * 2/16
h = 4.472
So the height is 4.472
Goes right 7 and down 8
Answer: b
All you have to do is find the slope of the graph.
1) Pick 2 points: (8,9) and (16,18) for example
2) Use the slope formula (y2-y1)/(x2-x1)
3) Once you know the slope, you know how much the graph will rise for each x-unit. Find the x distance between 24 and the new point (36), and use can calculate how high the y value should be
