So, if a long distance call costs 21 cents we just use a formula first we do 20 - 9.92, which gives us 10.08, then we divide it like this: 10.08 / 0.21, which gives 48! So, Lashonda spent 48 minutes making a long distance call! Hope this helped! Brainliest is always appreciated.
<span>This is decay. The exponent has a negative sign. The reciprocal of 2 is 0.5. So N(t) can be rewritten as 0.5^(t/8). The base is fraction less than 1, which is decay.</span>
