The answer is: A
Cause I had this test before and I aced it ;)
Answer:
36 <127
(36,127°)
36 [ cos (127) + i sin (127)]
Step-by-step explanation:
w1 = 2 < 95
w2 = 18 < 32
w1 * w2
We multiply the magnitude and add the angles
w1 * w2 = 2*18 < (95+32)
=36 < 127
36 [ cos (127) + i sin (127)]
Answer:
Step-by-step explanation:
<u>Full charge can be expressed as equation:</u>
- c = 2.5 + 0.75m, where c- charge, m- miles
<u>The limit for charge is $13, then we got inequality:</u>
- 0.75m + 2.5 ≤ 13
- 0.75m ≤ 9.5
- m ≤ 9.5/0.75
- m ≤ 12.66
Option B: 10 is correct as the only number satisfying the inequality
It would be D
Hope this helps! :)
