10. Is the relationship between the variables in the table a direct variation, an inverse variation,
both, or neither? If it is a direct or inverse variation, write a function to model it.
x 2 5 12 20
y 30 12 5 3

direct variation; y = 15x
60
inverse variation; y=
direct variation; y = 2x + 2
neither
X

Step-by-step explanation:

For direct variation, an increase or decrease in one variable would lead to a corresponding increase or decrease in the other variable.

For inverse variation, an increase or decrease in one variable would lead to a corresponding decrease or increase in the other variable.

From the given table, as the value of x is increasing, the value of y is decreasing. It means that it is an inverse variation.

Assuming a constant of variation, k then,

y = k/x

k = yx

When y = 30 and x = 2,

k = 30 × 2 = 60

Therefore, the function to model the inverse variation is

y = 60/x

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
