solmaris [256]

Answer:

Step 1

Formulate a recursive sequence modeling the number of grams after n  minutes.

we have that

100%-17.1%-------------- > 82.9%------------> 0.829

a(n) = 780*[0.829^n]

for n=19 minutes

a(19)=780*[0.829^(19)]=22.1121 g---------------> 22.1 g

the answer is 22.1 g

Will the standard form 3.2 × 10–4 be more or less than 1? Explain what effect the negative exponent has. Thanks! =)
laila [671]
3.2 * 10^-4 = 0.00032
So the number is less than 1.

The effect the negative exponent has is.....well...here's an example

if the exponent was a positive it would be 3.2 *10^4 = 32,000

If it was positive you would move the decimal point to the right (for this equation) 4 times... if it was negative you would move it the other way.
