Use the properties of exponents to rewrite y=3e^-0.6t in the form y=a(1+r)^t or y=a(1-r)^t. Round the value or r to the nearest thousandth. Then find the percent rate of change to the nearest tenth of a percent. Rewritten function:
The percent decrease is about___%
1 answer:
Answer:
The value of r is 0.451
The percentage decrease is about 45.1%
Step-by-step explanation:
The given exponential function is
Using the exponent rule,
Now the value of
Thus, we can rewrite the function as
Therefore, the function in form
The value of r is 0.451
The percentage decrease is about 0.451 ×100 = 45.1%

Quotient is simply the result of dividing.
Hey there! To solve this, divide the numbers 1/4 and 5 . . . 1/4 = 1/4 5 = 5/1 1 x 1 = 1 4 x 5 = 20 = 1/20 1/20 is already in it's simplest form, so it doesn't need to be simplified.There are 1/20 liters of water in each glass. Hope this helps you. Have a great day!
