Answer:
s(t) = 10000·1.65^t
Step-by-step explanation:
The general form of an exponential model is ...
f(t) = (initial value) × (1 +(fractional change))^t
where the fractional change can be positive or negative and t is the number of time units. Each time unit will correspond to the period required for the fractional change.*
__
For your problem, you have (initial value) = 10,000 and (fractional change) = 65% = 0.65 with time units of 1 year. Your function for sales (s) will then be ...
s(t) = 10000·1.65^t
_____
* The business regarding time units has to do with problems where you get a description like "increased 30% in 4 hours." Then, if t is in hours, the multiplier of the initial value looks like 1.30^(t/4).
For part (a) the answer is 400 grams for part (b) 198.63 grams and for part (c) 20 years.
<h3>What is exponential decay?</h3>
During exponential decay, a quantity falls slowly at first before rapidly decreasing. The exponential decay formula is used to calculate population decline and can also be used to calculate half-life.
We have an equation for radioactive decay:
a) Plug t = 0
m(0) = 400 grams
b) plug t = 20 years
After solving:
m(20) = 198.63 grams
c) Plug m(t) = m(0)/2 = 400/2 = 200 grams
x = 19.80 years ≈ 20 years
Thus, for part (a) the answer is 400 grams for part (b) 198.63 grams and for part (c) 20 years.

THE ANSWER IS 49.50
Because if you divide 55 and 10 it gives you 5.5. So with that answer you just subtract to the price of the jeans giving you 49.50
Answer:
3n+5
Step-by-step explanation:
Like terms are the terms that can be added together, in this example, 7 and -2. There aren't any other like terms so if you add them together, the answer would be 3n+5.
