y is directly proportional to c, and y = 60 when x = 10. Write a direct proportion equation that relates to y and x

y=6x

Step-by-step explanation:

y=kx

find k, which is constant

y=60, x= 10

60=k10

divide both sides by 10

k=6

therefore, the equation relates y and x is;

y=6x

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.
