Assuming that what you want me to solve is how much she paid for "extra use", the answer is she paid 20 times for the extra charge
47 - 32 = 15
20x .75 = 15
Answer:
Use z = a +bi = IzI (cos (Ф) + i sin (Ф)) to find the trigonometric form. √2+∛ / 2 (cos (0) + i sin (0))
Step-by-step explanation:
Answer:
r = -6, -1
Step-by-step explanation:
r^2 + 7r+6 =0
Factor
What 2 numbers multiply to 6 and add to 7
6*1 =6
6+1 =7
(r+6) (r+1) =0
Using the zero product property
r+6 =0 r+1 =0
r = -6 r=-1
I think 140 is the answer
