Answer:
c.
Step-by-step explanation:
<span>If tan theta= 15/8, then theta is expected that theta is found in the first and third quadrant. the y-component is 15 and the x-component is 8. hence the hypotenuse is 17 from the pythagoren theorem. cos theta thus is equal to 8/17, sec theta is equal to 17/8. csc theta is equal to 17/15. answer are A and D</span>
Answer:
Required series is:

Step-by-step explanation:
Given that
---(1)
We know that:
---(2)
Comparing (1) and (2)
---- (3)
Using power series expansion for 


![=-[c+\sum\limits^{ \infty}_{n=0} (-1)^{n}\frac{x^{2n+1}}{2n+1}]](https://tex.z-dn.net/?f=%3D-%5Bc%2B%5Csum%5Climits%5E%7B%20%5Cinfty%7D_%7Bn%3D0%7D%20%28-1%29%5E%7Bn%7D%5Cfrac%7Bx%5E%7B2n%2B1%7D%7D%7B2n%2B1%7D%5D)

Hence,

X=10, the two triangles are alike except one is double the size of the other. hope this helps
The correct answer is option B which is the actual product is about StartFraction 1 over 18 EndFraction less than the estimate.
<h3>What are fractions?</h3>
The fraction is defined as the division of the whole part into an equal number of parts. here we have the following information Vassil rounded to the nearest half to estimate the product of Five-eighths and StartFraction 8 over 9 EndFraction.
E =
= 0.55
Thus the product of the fraction estimated in the nearest half is,
0.5×1= 0.50
Therefore the correct answer is option B which is the actual product is about StartFraction 1 over 18 EndFraction less than the estimate.
