c
Step-by-step explanation:
divide it by 5x. the rest of this is all just to fill up the space that I have to have to put the answer you can ignore it
A rational number can be expressed as a fraction with an integer numerator and denominator. The square root of 2 is irrational, and adding 4.2 doesn't change this, since there are no integers that, when divided, form this sum.
If A={1,2,3,4,5},B={4,5,6,7} and C={2,3,4}find (A-B)-C

Answer:
(A - B) - C = { 1 , 4 , 6 , 7 }
Step-by-step explanation:
A = { 1 , 2 , 3 , 4 , 5 }
B = { 4 , 5 , 6 , 7 }
A - B = { 1 , 2, 3 ,6 , 7 }
C = { 2 , 3 , 4 }
(A - B) - C = { 1 , 4 , 6 , 7 }
Answer:
NEITHER I THINK
Step-by-step explanation:
OK. I used my calculator to evaluate sec(85 degrees).
My calculator doesn't have a "sec" button on it.
But I remembered that
sec of an angle = 1 / (cosine of the same angle) .
So I used my calculator to find cos(85), and then I hit the
" 1/x " key, and got 11.474, which I knew to be sec(85).
