F(n) = 1st term - common difference (n - 1)
The operation is subtraction because the sequence is decreasing.
n = number of the term you are looking for
1st term = 1st number in the sequence, in this case, 16
common difference = difference between one number to the next
f(n) = 16 - 1(n-1)
Assuming we are looking for the 5th term.
f(5) = 16 - 1(5-1)
= 16 - 1(4)
= 16 - 4
= 12 * as you can see, 12 is the 5th term of the sequence.
If you are looking for the equivalent of the nth term, simply substitute n by the number you are looking for and solve the equation.
soln,
circumference of circle = 11.27π ft
so,
C = 2πr
or, 11.27π = 2πr
or, 11.27π/2π = r
so, r = 5.635 ft
now,
diameter = 2r
= 2 x 5.635
= 11.27 ft
Can you upload a picture pls so i can help you
Answer:
684 mm squared
Step-by-step explanation:
Very simple. It's 18mm multiplied by 38 mm.
18 mm * 38 mm = 684 mm2
(-1,5) = (x1,y1)
(3,13) = (x2,y2)
slope(m) = (y2-y1)/(x2-x1)
= 2
by using slope point form
y-y1 = m (x-x1)
y-5 = 2(x+1)
2x-y+7=0
