Answer:
Hi! If y varies directly as x, then k=y/x. If this is the case then, as y increases, x should increase also by the same factor.
Step-by-step explanation:
1. y varies directly as x: k=y/x or y=x*k; K is the constant or the factor that dictates the increase or decrease of y or x.
Hopefully that makes since! There is a good article on SparkNotes that explains this concept better I think.
For this, it is kind of like a triangle and having to find the diagonal. Let's see what the two legs of the triangle would be.
Leg one= 7 units
Leg two= 8 units
8²+7²= c²
64 + 49=113
√113≈10.6
The line is 10.6 units long.
So in this case use sine to figure this out.
To convert 48 to the ratio, you gotta use a calculator unless you've memorized everything. do sin(48), which equals about 0.74.
Since Sin is opposite / hypotenuse, 5/h must equal 0.74
So do 5 / 0.74 to get about 6.76 as your answer.
