I’m not 100% sure but isn’t it x2 +xy +y2?
Answer:
60.2 m
Step-by-step explanation:
Let x represent the width of the river. The distance from the point across from the tree to the second point is 15 m. The angle from this point to the tree across the river is 76°.
This makes the side opposite the angle x, the width of the river. It also means the 15 m side is adjacent to this angle.
The ratio opposite/adjacent is the ratio for tangent; this gives us the equation
x/15 = tan(76)
Multiply both sides by 15:
15(x/15) = 15(tan(76))
x = 15(tan(76)) ≈ 60.2
Hey there!
The answer to your question is:
Graph A represents a growth.
Graph B represents a decay.
Graph C represents a growth.
I will give an explanation any way.
Graph A has a positive slope - a growth.
Graph B has a negative slope - a decay.
Graph C has a positive slope - a growth.
Good luck on your assignment! Hope it helps, and have a great day!
Here is a note: the sum of the 2 shorter sides have to be greater than the longest side. Sorry that i cant help more.
