Question

i. iv. V. nt ch The damn bank didn't approve the 2.25-million-dollar loan to SambrineMobile, but they did approve 1.5 million dollars. So, the company needs to lower its standards a bit: we don't offer excellent reception everywhere in the city, but we do offer at least good reception. 5. Recall that SINR is a measure for the quality of the signal. It starts at 16 right at the cell tower and decays-3.23% a mile on the most humid of days. You made a function for this and looks something like this: SINR 1 6e"(-0.0323d) where d is the number of miles away from the cell tower Here's the quality table. Quality SINR Bars 5 Good Fair Poor 12.5 or higher 10-12.5 7-10 Less than 7

Explanation / Answer

SINR = 16e^(-0.0323d)

Plug in 10 :
10 = 16e^(-0.0323d)

0.625 = e^(-0.0323d)

-0.4700036292457356 = -0.0323d

d = 14.55

Now, plug in SINR to be 12.5 :
12.5 = 16e^(-0.0323d)

0.78125 = e^(-0.0323d)

-0.2468600779315258 = -0.0323d

d = 7.6427

The new radius can be anything between
7.64 to 14.55 miles
