Whether this equation represents a direct proportion? 0.4 Y = X If so, identify the value of Constant of proportionality

it is a direct proportion

The constant of proportionality is 0.4

Step-by-step explanation:

0.4 Y = X

Direct proportion can be written as

x = ky

Where,

k = constant of proportionality

0.4 Y = X can also be written as

x = 0.4y it is a direct proportion

The constant of proportionality is 0.4

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
