We are told that f(1) = -1.5, and that f(n+1) = -2f(n).
Then: f(2) = -2f(1) = -2(-1.5) = +3 (answer)

Answer:
Step-by-step explanation:
Given Annabella time for a race is 24.2 seconds, if another runnee's time was 6.43 seconds faster, then the time taken for another runnee's time will be 24.2 - 6.43 = 17.77secs.
Let a variable X be the difference between annabelle's time and the other runners time.
X = annabelle's time - other runners time.
X = 24.2 - (24.2 - 6.43)
X = 24.2-24.2+6.43
X = 6.43seconds
Hence the expression between annabelle's time and the other runners time is X = 24.2 - (24.2 - 6.43)
<em>The difference between annabelle's time and the other runners time is 6.43seconds</em>
Given:
![$\frac{7}{r}+2^{3}+\frac{s}{3}+11](https://tex.z-dn.net/?f=%24%5Cfrac%7B7%7D%7Br%7D%2B2%5E%7B3%7D%2B%5Cfrac%7Bs%7D%7B3%7D%2B11)
To find:
Which statement are true?
Solution:
Option A: The entire expression is a sum.
It is true because it performed addition operation.
Option B: The coefficient of s is 3.
![$\frac{7}{r}+2^{3}+\frac{s}{3}+11=\frac{7}{r}+2^{3}+\frac{1}{3}s+11](https://tex.z-dn.net/?f=%24%5Cfrac%7B7%7D%7Br%7D%2B2%5E%7B3%7D%2B%5Cfrac%7Bs%7D%7B3%7D%2B11%3D%5Cfrac%7B7%7D%7Br%7D%2B2%5E%7B3%7D%2B%5Cfrac%7B1%7D%7B3%7Ds%2B11)
It is not true because the coefficient of s is
.
Option C: The term
is a quotient.
If we divide 7 by r, we obtain a quotient.
So it is true.
Option D: The term
has a variable.
It is not true because it does not contain any variable.
Therefore the entire expression is a sum and the term
is a quotient are true statement.
