Answer:
g(1) = -65; g(n) = g(n-1) -15
Step-by-step explanation:
Using n = 1, 2, 3, we can find the first three terms of the sequence:
g(1) = -50 -15 = -65
g(2) = -50 -15(2) = -80
g(3) = -50 -15(3) = -95
The first term of the arithmetic sequence is -65, so that is g(1). Each next term is 15 less than the one before, so the recursive formula is ...
g(n) = g(n-1) -15
The complete recursive function definition requires both parts:
g(1) = -65
g(n) = g(n-1) -15
The correct answer is B) -8.9%
The rate of change for any problem is always determined using the following equation.
In this case, the old value is 3.15 and the new value is 2.87. SO we use these in the equation to get the answer.
-.088889 * 100
-8.9%
Answer:
150
Step-by-step explanation:
255 - 99 = ?
255 can become 250
99 can become 100
250 - 100 = 150
To check, 255-99 = 156 so our answer seems to be correct and a close estimate! ✔
