Answer:
Step-by-step explanation:
You can calculate the length of side a using the Cosine Rule:
a^2 = 32.6^2 + 41.4^2 - 2.32.6.42.4 cos pi/6
a^2 = 456.01
a = √456.01
a = 21.35
By the Sine Rule:
32.6 / sin B = 21.35 / sin pi/6
sin B = (32.6 * sin pi/6) / 21.35
sin B = 0.76347
B = 0.869 radians.
C = pi - pi/6 - 0.869 = 1.749 radians.
The limand is continuous at <em>x</em> = -1, so
Answer:
105,660 times
Step-by-step explanation:
7 times 65=445 times 60=26 700
2 times 118=236 times60=14 160
15 times 72=1080 times 60=64 800
26700 plus 14 160 plus 64 800=105,660

1st answer: x= -7/2 -5/4y + 1/2z
2nd answer: x= 6 + 1/7y -2/7z
3rd answer: x= 28/3 -1/3y -4/3z
Steps
4x + 5y -2z = -14
Move variables to the right
4x = -14 -5y +2z
Divide both sides by 4
X= -7/2 -5/4y +1/2z
Answer
X= -7/2 -5/4y +1/2z
7x -y +2z =42
Move variables to the right
7x = 42 +y -2z
Divide both sides by 7
X= 6 + 1/7y -2/7z
Answer
X= 6 + 1/7y -2/7z
3x +y +4z = 28
Move variables to the right
3x =28 -y -4z
Divide both sides by 3
X= 28/3 -1/3y -4/3z
Answer
X= 28/3 -1/3y -4/3z
