Answer:
5
Step-by-step explanation:
AC=AB+BC
so 16=x+1+x+7
which simplifies to 16=2x+8
subtract eight from both sides to get 8=2x
then divide by 2 to get that x=4
AB=x+1, which substitutes into 4+1=5
Answer:
cos 15 degrees is your answer.
Answer choice (b)
Answer:
42.40705%
Step-by-step explanation:
(1 - (23/100)^(19/9) = 1 + r/100
0.57593 = 1 + r/100
r = 42.40705%
Step-by-step explanation:
8t³-80t²+200t
= 8(t³-10t+25)
= 8t(t²-10t+25)
= 8t(t-5)(t-5)
= 8t(t-5)²
the answer is B.
