Write n as a discrete exponential function of t of the form n(t)=a(1+r)t. (hint: you will need to find (1+r), where r is the rate. use n(11)=130 and the initial value n(0)=84 to find it.)

.

Step-by-step explanation:

We have been given that and . We are asked to write N as a discrete exponential function of t of the form .

Using our given information, we can set an equation as:

Using our given information, we will get:

Substitute the given values:

Switch sides:

Take 11th root of both sides:

Therefore, our required function would be .

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
