Answer:
nth term is;
0.5n-0.5
Step-by-step explanation:
As we can see, the first term is 0
The common difference is 0.5-0= 1-0.5 = 1.5-1 = 0.5
Formula for nth term of an arithmetic sequence is;
a + (n-1)d
So we have
0 + (n-1) 0.5
= 0.5n-0.5
Step-by-step explanation:
Put the interior angle equal to 180.
It would look something like this:
x+45=180
-45 -45
180-45= 135 so the exterior angle would be 135!
Answer:
x = 5
Step-by-step explanation:
Given
f(x) = - 3x + 21 and f(x) = 6, then equating gives
- 3x + 21 = 6 ( subtract 21 from both sides )
- 3x = - 15 ( divide both sides by - 3 )
x = 5
