B. 25 Km. The measure of BC is 25 km.
The easiest way to solve this problem is using the cosine theorem c = √a²+b²-2ab*cos A.
BC = √AC²+AB²-2(AC)(AB)*cos A
BC = √(21km)²+(14km)²-2(21km)(14km)*cos 89°
BC = √441km²+196km²-588km²*(0.017)
BC =√637km²-10.26km²
BC = √636.74km²
BC = 25.03km ≅ 25
F(x)=|x-5|+2
plug it in
so f(3)
f3)=|3-5|+2
solve whats inside first
|-2|+2
since its absolute value its actually positive
2+2

Your answer is C.) 4
Answer:
Step-by-step explanation:
<u>Given inequality</u>
- |x+6| - 12 < 13
- |x+6| < 13 + 12
- |x+6| < 25
To solve this inequality graphically you need two graphs according left and right sides of inequality
<u>So the graphs should be:</u>
See attached for the graph
Answer:
See Below
Step-by-step explanation:
1) 180 ft / 6 sec
You can divide both the numerator and denominator by 6:
30 ft / 1 sec
2) 86 mi/5 hr
You can divide 86 by 5:
17.2 mi / hr
3) 83 mi / 5hr
Same as above ^
16.6 mi / hr --> 16.6 mph
4) 93 feet / 5 sec
Same as above ^^
18.6 ft/ 1 sec
5) 150 mi / 4 hr
Same as above ^^^
37.5 mi / 1 hr --> 37.5 mph
