<u>Given</u>:
Given that the first term of the geometric sequence is 729.
The common ratio is 
We need to determine the seventh term of the sequence.
<u>Seventh term</u>:
The seventh term of the sequence can be determined using the formula,
To find the seventh term, let us substitute n = 7 in the above formula, we get;
Now, substituting 
and 
, we get;
Thus, the seventh term of the geometric sequence is 1.
Answer:
60
Step-by-step explanation:
You dont have enough infor, but if its 120 degrees, A total degree of a triangle is 180, so 180-120 equals 60
4x - 5y = -15
y = -3x + 22
Plug in your y= equation into the y variable in the other equation
4x - 5 (y) = -15
^^
y = (-3x + 22) = -15
4x - 5 (-3x + 22) = -15
Distribute
4x + 15x - 110 = -15
Combine like terms and add 110 over to -15
19x = 95
Then, divide the whole equation by 19
x = 5
Then, plug in your x into your y= equation
y = -3 (5) + 22
y = -15 + 22
y = 7
<em><u>x = 5</u></em>
<em><u>y = 7</u></em>
<em><u>(5, 7)</u></em>
Answer:
3 (-1 / x^25)^1/5.
Step-by-step explanation:
(-243x^(-25))^((1)/(5))
= ( (-243/ x^25 ))^ 1/5
= 3 (-1 / x^25)^1/5.
