Answer:
X= 140
Step-by-step explanation:
f(x) = x3 – 4x² - 6x – 32 at x = 6
(6)(6)(6) -4²=72
-6(6)-32= -68
72+68=140
30. is 8 [-5] [3] [-2] -2
Let the two sides of a right triangle be equal to one, which means that the hypotenuse is √2
Since cosa=adjacent side / hypotenuse
cos45=1/√2
We can rationalize the denominator by multiplying numerator and denominator by √2
√(2)/2
or if you prefer: √(1/2)
