Answer:
The number of miles Lori drive be 134 miles .
Step-by-step explanation:
Let us assume that the number of miles Lori be x.
As given
Lori rented a car for one day.
The daily rental rate was $12.50 plus 25 cents per mile.
As 1 dollar = 100 cent
As given
The total cost of her rental was $46.
Than the equation becomes
46 = 12.50 + 0.25x
46 - 12.50 = 0.25x
33.5 = 0.25x
x = 134 miles
Therefore the number of miles Lori drive be 134 miles .
When you multiply two complex numbers given in polar form, the argument of the product is the sum of the arguments of the factors. Meanwhile, the modulus of the product is the product of the moduli of the factors.
In this case, you'd have
and the modulus would simply be
. Since
we would expect the final product to fall in the first quadrant.
