Answer:
The slope of any line perpendicular to the given line is 3
Explanation:
The general form of the linear line is:
y = mx + c where m is the slope
The given line is:
y = -1/3 x + 22
Comparing the given line with the general form, we will find that:
slope of the given line (m1) is -1/3
Now, for any two lines to be perpendicular, the product of their slopes should be equal to -1.
This means that:
m1 * m2 = -1
We have m1 = -1/3
Therefore:
-1/3 * m2 = -1
m2 = 3*1
m2 = 3
Hope this helps :)
Answer:
The sum of first 50 terms is 3425.
Step-by-step explanation:
Let the first tem of A.P be 'a' and it's common difference be 'd'
Thus the 16th term of the A.P is given by
Now we know that the sum of first 'n' terms of the A.P is given by
![S_n=\frac{n}{2}[2a+(n-1)d]\\\\5=\frac{5}{2}[2a+4d]\\\\1=a+2d..........(ii)](https://tex.z-dn.net/?f=S_n%3D%5Cfrac%7Bn%7D%7B2%7D%5B2a%2B%28n-1%29d%5D%5C%5C%5C%5C5%3D%5Cfrac%7B5%7D%7B2%7D%5B2a%2B4d%5D%5C%5C%5C%5C1%3Da%2B2d..........%28ii%29)
Solving equation 'i' and 'ii' simultaneously we get
Thus 
Thus the sum of first 50 terms euals
![S_{50}=\frac{50}{2}[2\times -5+(50-1)3]\\\\S_{50}=3425.](https://tex.z-dn.net/?f=S_%7B50%7D%3D%5Cfrac%7B50%7D%7B2%7D%5B2%5Ctimes%20-5%2B%2850-1%293%5D%5C%5C%5C%5CS_%7B50%7D%3D3425.)
The answer is n=7 please mark Brainelist
