Answer:
- 4 and 3
Step-by-step explanation:
Given
f(n) = 7n - 11
To evaluate f(1) and f(2) substitute n = 1 and n = 2 into f(n), that is
f(1) = 7(1) - 11 = 7 - 11 = - 4
f(2) = 7(2) - 11 = 14 - 11 = 3
Answer:
3 to the fourth power, which equals 81.

Answer:
If z =1/2, which expression has the greatest value?
1. (z^-2 z^5)^-2 = (z^3)^-2 = 1/z^6 = 1/(1/2)^6 = 2^6 = 64
2. (z^3)^5 = z^15 = (1/2)^15 = 1/(2^15)
3. z^-6 z^4 = z^-2 = (1/2)^-2 = 1/2^2 = 1/4
4.-(z^2 z^-4)^-3 is negative 64
Answer:
Let b be the number of branches that the shrub will have after m months, since the shrub has an initial amount of 12 branches and the shrub grows 4 new branches every month, then we can set the following equation:
Evaluating the above equation at m=7 we get:
Simplifying the above result we get that the shrub will have
branches after 7 months.
