21) A tour bus holds 40 people. It charges $7 per ticket. The function representing the total sales is fx) = 7x, where x represents the number of tickets sold. What is the domain? A) X = all real numbers
B) x = all non-negative integers 280 or belowx = all non-negative integers 40 or below
C) x <=40
D)x = all non-negative integers 40 or below

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.

it is x=-4

step-by-step explanation:

hi there!

question 1 answer: p/q can be terminating when q = 5^m * 2^n

question 2 answer: -1 and -1

question 3 answer: -4

question 4 answer: 5/12

hope this : )
