The answer is $116.18. 135 is 116.2% of the previous year.
Answer:
=135.53°
Step-by-step explanation:
The bearing that the captain should turn is the angle difference between the two islands from the position of the ship.
Let C be the position of the ship, then
AB is c=160
AC is b=220
BC is a=200
We use the cosine rule as follows:
c²=a²+b²-2ab Cos C
160²=200²+220²-2×200×220 Cos C
25600=88400-88000Cos C
88000 Cos C=88400-25600
88000Cos C=62800
Divide both sides by 88000.
Cos C=62800/88000
=0.7136
C=44.47°
He should turn (180°-44.47°)=135.53°
Answer:
The answer to your question is: k(-5) = -115
Step-by-step explanation:
Function k(n) = n³ - 3n find k(-5)
k(-5) = (-5)³ - 3(-5) substitution
k(-5) = -125 + 15 simplify
k(-5) = -115
<h2>Answer: it is 16.25.</h2>
Answer:
x=-2
Step-by-step explanation:
5x+4=-6 so basically what you want to do is try to get x by itself
step 1 subtract 4 from each side
5x=-10
step 2 divide each side by 5
x=-2
