I believe it is C because I think 0 is actually not an integer
A,5.39.
2-0 and 5-0
5²+2²=√29=5.39
Answer:
3rd option
Step-by-step explanation:
The sum to infinity of a geometric sequence is
S = ![\frac{a}{1-r}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7B1-r%7D)
where a is the first term and r the common ratio
The expression inside the summation is
6 ![(\frac{1}{3}) ^{n-1}](https://tex.z-dn.net/?f=%28%5Cfrac%7B1%7D%7B3%7D%29%20%5E%7Bn-1%7D)
which is in the form of the nth term of a geometric sequence
with a = 6 and r =
, then
S =
← expression required
= ![\frac{6}{\frac{2}{3} }](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B%5Cfrac%7B2%7D%7B3%7D%20%7D)
= 9
Answer:
x is equal to 24 and y is equal to 66.
Step-by-step explanation:
In order to find the value of y, we first have to note that the unlabeled angle in the larger triangle, y and the 78 degree angle create a straight line. The unlabeled angle is equal to 36 since it and the other two angles equal 180. So we take that 36, 78 and y and can set that equal to 180.
36 + 78 + y = 180
114 + y = 180
y = 66
Now that we have that value, we can use y and the 90 degree angle to find x.
x + y + 90 = 180
x + 66 + 90 = 180
x + 156 = 180
x = 24
