What is the factorization of 81a6 -100

see explanation

Step-by-step explanation:

81 - 100 ← is a difference of squares which factors in general as

a² - b² = (a - b)(a + b)

81 = (9a³ )² ⇒ a = 9a³ and 100 = 10² ⇒ b = 10

Hence

81 - 100

= (9a³)² - 10²

= (9a³ - 10)(9a³ + 10)

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.

the answer is c hope it
