Answer:
D
Step-by-step explanation:
change minutes to degrees
60minutes=1degree
47 mutes=?
47/60=0.78333333°
Add to 52°
52° + 0.78333333°
52.78333333°
so sin 52.7833 =0.7963540136
Step-by-step explanation:
the answer is C.
I hope it will be help you.....
To expand the given expression we proceed as follows:
(6x²-2x-6)(8x²+7x+8)
=6x²(8x²+7x+8)-2x(8x²+7x+8)-6(8x²+7x+8)
=48x⁴+42x³+48x²-16x³-14x²-16x-48x²-42x-48
putting like terms together:
48x⁴+(42x³-16x³)+(48x²-48x²)+(-16x-42x)-48
=48x⁴+26x³+0x²-58x-48
hence the answer is:
48x⁴+26x³-58x-48
