Answer:
26042.
Step-by-step explanation:
What's the first term of this geometric series?
2.
What's the common ratio of this geometric series?
Divide one of the terms with the previous term. For example, divide the second term -10 with the first term 2.
.
What's the sum of this series to the seventh term?
The sum of the first n terms of a geometric series is:
,
where
- is the first term of the series,
- is the common ratio of the series, and
- is the number of terms in this series.
.
Answer:
30 degrees
Step-by-step explanation:
Let Angle ABC be 2x, Angle EBC be 5x
5^-3 is 1/125
The negative in the exponent makes it so there is a 1 over the problem if there was no negative. When you have a negative in the exponent, the answer will be the reciprocal (opposite) of the question with no negative.
For example,
9^2 = 81
9^-2 = 1/81
Answer:x= -3/8
Step-by-step explanation:
Answer:
y = 5x - 4
Step-by-step explanation:
5 is the slope so it goes in front of the x and -4 is the y Intercept so it goes last.
