3) a cellular phone network uses towers to transmit calls. each tower transmits to acircular area. on a grid of a city, the coordinates of theity, the coordinates of the location and the radius eachtower covers are as follows (integers represent miles): tower a is at (1, -2), and coversa 3 mile radius and tower b is at (-5, 3) and covers a 5 mile radius. if you werestanding at a point x (-0.5, 0.5) would you be able to call your friend (are you in cellphone range)? ao-10 -86-42

What is the solution of log2  (3x  -  7)  =  3? 4 5

Complex numbers multiply √-4 * √-25 and show all intermediate steps. alternative notation is sqrt(-4) * sqrt(-25).

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
