Answer:
b = 8
c = 16
Step-by-step explanation:
From the given right triangle,
a = 
, m(∠B) = 30°
By applying sine rule in the given triangle,
cos(B) = 
cos(B) = 
cos(30°) = 
c = 16
Further we apply tangent rule,
tan(B) = 
tan(30°) = 
b = 8
Answer:
0
Step-by-step explanation:
x2 +4x-21=0. solve for x
Answer: 2 2/5 distance
Step-by-step explanation:
You know 1/4 of an hour you travel of 3/5 of distance, so let’s set an proportion: 1/4 hr = 3/5 of distance, multiply 4 on both sides, and you get 2 2/5 distance. Hope this helps!
5p - 3q = -39
- (-2p - 3q = 3)
==> 7p = -42 ==> p = -6
==> p = -6
-2(-6) - 3q = 3 ==> 12 - 3q = 3
==>p = -6
-3q = 3 - 12 ==> -3q = -9
==> p = -6
q = 3
Step-by-step explanation:
domain is all real numbers since its quadratic: (-infinity, infinity)
Range is from -6 to positive infinity or [-6, infinity)
