Answer:Tn=29-2n
Step-by-step explanation:
Firstly u determine the differences between the terms and see if it's common. These case the common difference is -2 which means these is a linear pattern.
Now Tn=a+(n-1)d
Tn=27+(n-1)(-2)
Tn=27-2n+2
Tn=29-2n
Answer:
Step-by-step explanation:
y(x) and f(x) are similar in meaning; they both state that the dependent variable is a function of the independent variable x.
f(x) = 5x = y(x).
Answer:
The circle's area is pi
Step-by-step explanation:
A=πr2=π·12≈3.14159...
The formula for finding the height of an octagon from only one side is h=s(1 + the square root of 2). S is the length of one side. Your formula would be h=18(1 + the square root of 2).
h=18+18(the square root of 2)
h=18 + 25.4558
h=43.4558
Hope this helps!! :) And the decimal is rounded, just so you know ;). If your teacher likes everything in simplest radical form, then just don't convert the 18*the square root of 2 into a decimal and solve as you normally would.
