Answer:
29
Just replace n by 8 ===> C(8) = -6+5(8-1) = - 6 + 5x7 = -6+35 = 29
Step-by-step explanation:
We have been given a sequence formula. We are asked to find the 8th term of our given sequence.
We know that an arithmetic sequence is in form A_n=a_1+(n-1)d, where,
A_n=\text{ nth term of sequence},
A_1=\text{ 1st term of sequence},
n = Number of terms in sequence,
d = Common difference.
To find the 8th term of our given sequence, we will substitute n=8 in our given formula.
c(n)=-6+5(n-1)
c(8)=-6+5(8-1)
c(8)=-6+5(7)
c(8)=-6+35
Answer:
12^1 = 12
Step-by-step explanation:
Any number raised to the power of one equals the number itself.
We know that an equilateral triangle has all sides equal.
Initial perimeter = s + s + s = s
Each side has been increases by then the new perimeter is:
(s+15) + (s+15) + (s+15) = 3s + 45
So the new perimeter = 3s + 45
Since angle 2 is 120 degrees, the corresponding angle is 6, so 6 will also be 120 degrees
6 and 8 should form 180 degrees
180 - 120 = 60
so angle 8 is 60 degrees
