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 : -4a+10
Substitute (a-3) for x
-4(a-3)-2
-4a+12-2
-4a+10 but can also be written as -2(2a-5)
Answer: 33 tulips bloomed / 66 tulips did not bloom
Step-by-step explanation:
<h2>Given:</h2>
Total number of tulips = 99
Total number of tulips bloomed = 3/9 of total
<h2>Solve:</h2>
Step One: Find the number of tulips that bloomed
99 × (3/9) = 99 × (1/3) = 33 tulips
Step Two: Find the number of tulips that did not bloom
99 - 33 = 66 tulips
Hope this helps!! :)
