Ahot air balloon went from an elevation of 4,538 feet to an elevation of 3,363 feet in 50 minutes. what
was its rate of descent?

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.

c.)

step-by-step explanation:

a 90 degree rotation across the the origin followed by a reflection across the x-axis.
