Answer:
Rational
Step-by-step explanation:
Its rational because it is a terminating decimal. Meaning that it doesn't go on and on like pie(3.14...).
3/5 is the probability that he will win, you must find a fraction which adds to make 100%.
2/5 would be the fraction for his probability to lose.
0.4 or 40%.
Answer:
-8i
Step-by-step explanation:
To multiply numbers is polar form
z1 = r1 ( cos theta 1 + i sin theta 1)
z2 = r2 ( cos theta 2 + i sin theta 2)
z1*z2 = r1*r2 (cos (theta1+theta2) + i sin (theta1+theta2)
z1 = 2(cos 70° + i sin 70°)
z2 = 4(cos 200+ i sin 200)
z1z2 = 2*4 (cos (70+200) + i sin (70+200)
z1z2 = 8 (cos(270) + i sin (270))
= 8 (0 + i (-1))
=-8i
Answer:
y=1/2x
Step-by-step explanation:
Look at the graph, all you need is the first point.
Y is at 4 and X is at 2. We can divide y/x to get 4/2=1/2x
5 × x = 1/4 x = 1/4 ÷ 5 x = 1/20
