Answer:
f(x) = 4·3^x
Step-by-step explanation:
We assume the function will be of the form ...
f(x) = a·b^x
Substituting the given values, we can find 'a' and 'b'.
4/9 = a·b^(-2)
108 = a·b^3
Dividing the second equation by the first gives ...
108/(4/9) = b^(3 -(-2))
243 = b^5
b = 3 . . . . . . 5th root
Using the second equation, we can find 'a':
108 = a·3^3 = 27a
a = 108/27 = 4
The formula for the exponential function is ...
f(x) = 4·3^x
Answer:
well.. 1/1/1 would be 1.
8 x 3 = 24
24x 1 = 24
sooo the answer would be 24...
Step-by-step explanation:
Given:
Price paid including tax: $37.48
sales tax = 5%
This means that $37.48 is equivalent to 105%
To get the value of the 100% or its original price, we divide the price paid by its percentage rate
$37.48 ÷ 1.05 = $35.70 value of the original price
$35.70 * 5% = $1.78 value of sales tax
$35.70 + 1.78 = $37.48
