Answer:
D. 1.2
Step-by-step explanation:
The sum of an arithmetic sequence is the product of the average term value and the number of terms.
The average term is often computed by averaging the first and last terms of the sequence. It can also be computed by averaging the middle two terms of the sequence (when there are an even number of terms, as here).
We are given a_13 is 1.9. We know that a_12 is 3.7 less, so is -1.8. Then the average of these two middle terms is ...
... (-1.8 + 1.9)/2 = 0.05
The product of this value and the number of terms (24) is ...
... 24·0.05 = 1.2 . . . . . the sum of 24 terms of the sequence
Hey there! :D
Plug in the values (0,5) -> (x,y)
5=0+5
5=5
This does satisfy the equation.
I hope this helps!

Answer:
answer: 9
Step-by-step explanation:
Assuming this is the Pythagorean theorem the formula is a²+ b² = c² so we arent given a but we are given c so we have to work backwards c = 15 and 15 × 15 = 225 12 × 12 = 144 225 - 144 = 81 so Now we just have to figure out what multiplied by itself equals 81 therefore 9 is our answer because 9 × 9 = 81 Hope that helps!
<h3>Answer:</h3>
- The line is horizontal.
- The rise is zero.
<h3>Explanation:</h3>
Slope is (rise/run). When it is zero, rise=0. A line with zero slope goes neither up nor down. It is horizontal, not vertical.
When run is zero, the line is vertical, and the slope is <em>undefined</em> (not <em>zero</em>).
