Answer:
A = 0.65
B = 3.304
C = 6.07
Step-by-step explanation:
You have to subtract to the final result the initial one and divide it for the number of segments. Then, for every segment you add the number you found, for example:
Value of a segment:
![\frac{1 - 0.5}{10} = 0.05](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%20-%200.5%7D%7B10%7D%20%20%3D%200.05)
Value of A:
![0.5 + 3 \times 0.05 = 0.65](https://tex.z-dn.net/?f=0.5%20%2B%203%20%5Ctimes%200.05%20%3D%200.65)
We have to determine the value of ![\sum _{m=9} ^{21} (5m+6)](https://tex.z-dn.net/?f=%5Csum%20_%7Bm%3D9%7D%20%5E%7B21%7D%20%285m%2B6%29)
= (5(9)+6) + (5(10)+6) +(5(11)+6) + .......... + (5(21)+6)
= 51+56+61+66+ ........ + 111
Since, the common difference is 5, hence this series is in arithmetic progression.
Sum of AP is given by the formula:
![\frac{n}{2}[2a+(n-1)d]](https://tex.z-dn.net/?f=%5Cfrac%7Bn%7D%7B2%7D%5B2a%2B%28n-1%29d%5D)
Since, there are 13 terms.
= ![\frac{13}{2}[2(51)+(13-1)5]](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B2%7D%5B2%2851%29%2B%2813-1%295%5D)
= ![\frac{13}{2}[102+60]](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B2%7D%5B102%2B60%5D)
= ![\frac{13}{2}[162]](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B2%7D%5B162%5D)
= ![13 \times 81](https://tex.z-dn.net/?f=13%20%5Ctimes%2081)
= 1053
Therefore, the sum of the series is 1053.
So, Option G is the correct answer.
The answer is <span>B.The statement is true, but the inverse is false.
An acute angle is less than 90 degrees when talking about the terminal side. It inverse would be 360 - 43 = 317 degrees </span>
