Answer:
f(x) = x³+2x²-16x-32
Step-by-step explanation:
f(x) = 0 when x = -4, -2, 4
So these are the roots
Factors are (x+4)(x+2)(x-4)
f(x) = [(x+4)(x-4)](x+2)
f(x) = (x²-16)(x+2)
f(x) = x³+2x²-16x-32
Answer:
cos 240 deg = -1/2 and sin 240 = - root(3)/2
Step-by-step explanation:
if cos 60° = 1/2 and sin 60º = root 3/2 find cos 240° and sin 240".
we know that cos 240 = cos (60 + 180) = - cos 60 = - 1/2
cosine is negative when the angle is in the 3rd quadrant
sin 240 = sin (60 + 180) = - root(3) /2
sine is also negative in the 3rd quadrant.
We are given that:
5[2p-4(p+5)]=25
<span>
First thing to do is to divide everything by 5 so that:</span>
2p-4(p+5)=5
Then distribute -4:
2p – 4p – 20 = 5
Combine like terms:
-2p = 5 + 20
-2p = 25
<span>p = -12.5</span>
