Answer:
The first 5 terms are;
-2, 2, 13,38 and 91
Step-by-step explanation:
Here, we want to write the first 5 terms of the sequence.
We already have the first term as 1
Now, we need the 2nd term
Putting two in place of n, we have ;
2f(1) + 3n
= 2(-2) + 3(2) = -4 + 6 = 2
For the 3rd term, put 3 in place of n
2f(2) + 3(3)
sine f(2) = 2, we have
2(2) + 9 = 4+ 9 = 13
For the fourth term, put 4 in place of n, we have
2f(3) + 3(4)
since f(3) = 13
we have; 2(13) + 12 = 26 + 12 = 38
For the 5th term, put 5 in place of n, we have
2f(4) + 3(5)
since f(4) = 38, we have
2(38) + 15 = 76 + 15 = 91
Answer:
Percent Change Formula: [(new - old)/old] * 100
Step-by-step explanation:
New - old
80 - 20 = 60
Difference between new - old divided by old
60/20 = 3
Previous quotient times 100
3*100 = 300
Percent Change is 300%
Check your answer
300% of 20 is 60
20 + 60 = 80
Split the L into separate shapes. To do this, where the bit sticks out, cut it off and deal with it separately.
Answer:
23cm
Step-by-step explanation:
to convert from millimetres to centimetres, you divide by 10.
10mm= 1cm.
so 230mm = 23cm.
Answer:
x=5√2
Step-by-step explanation:
This is a right isosceles triangle, so the base and leg are the same. Both are x.
Pythagorean Theorem:
x²+x²=10²
2x²=100
x²=50
x=√50
x=5√2
