Answer:
= sqrt(53)
Step-by-step explanation:
|7-2i| means find the distance
d = sqrt(real part^2 + imaginary part^2)
= sqrt(7^2 + (-2)^2)
= sqrt(49+4)
= sqrt(53)
Answer:
1=(w=6,C=20.80
2=(W=2,C=27.05)
3=(w=11,C=14.25)
4=(w=15,C=11.05)
Step-by-step explanation:
Just do the work
0.55x15=8.25+2.80=11.05
1.10x6=6.6+14.20=20.8
11x0.65=7.15+7.10=14.25
Out of process of elimination, 2=(W=2,C=27.05)
96 yards = 288 feet
speed is 288/40 - 7.2 feet/s
