Answer:
The correct answer is f(3) = -294
Step-by-step explanation:
To find f(3), we have to find f(1) and f(2)
It is given that,
f(0)=5 and f(n+1)=-4f(n)+2
<u>To find f(1)</u>
using given information,
f(1) = -4f(0) + 2 = -4*5 + 2 = -20 +2 = -18
<u>To find f(2)</u>
f(2) = -4f(1) + 2 = -4*-18 + 2 = 72 + 2 = 74
<u>To find f(3)</u>
f(3) =-4f(2) + 2 = -4*74 + 2 =-296 + 2 = -294
Therefore the value of f(3) = -294
It is rational................

Step-by-step explanation:
Answer:
length of segment AB is 13
OR
AB = 13
Step-by-step explanation:
Use the Pythagorean Theorem with c being the length of segment AB.
a^2 + b^2 = c^2
5^2 + 12^2 = c^2
169 = c ^2 (square root both sides to get c by itself)
13 = c
Answer:
4
Step-by-step explanation:
If all were measure 5, the perimeter would be 30. The perimeter is 4 more than that. Each side that is 6 instead of 5 adds 1 to the perimeter, so there are 4 sides of length 6.
