Answer: 1) B is correct, constant of variation is -2.
Step-by-step explanation:
1)
Direct variation states that a relationship between the two variables. we say y varies directly as x
i.e, or y =kx.................[1] ; where k is the constant of variation.
Given the equation:
Divide both sides by -4 we get;
Simplify:
.......[2]
On comparing equation [2] with [1] we get;
k = -2
You would do 238855 divided by 75 ===3184.73333 mph
Step-by-step explanation:
it's 22 due to the sum all the 2 smallest sides bigger than the biggest
