Answer:
Step-by-step explanation:
You know it the answer is 5:12 so you add the 5 and 3 give you 8 then you get 5:12
The slope is the value in the term with "x". That is 2/9x has "x".
In this case, the slope will be 2/9
Answer:
120 ways.
Step-by-step explanation:
From the given information:
Total number of roads leading from Bluffton to Hardeeville = 4
Total number of roads leading from Hardeeville to Savannah = 6
Total number of roads leading from Savannah to Macon = 5
We need to find the total number of ways to get from Bluffton to Macon.
Total number of ways to get from Bluffton to Macon =
Therefore, there are 120 required number of ways to get from Bluffton to Macon.
Answer:
Identity is verified.
Step-by-step explanation:
We have to verify the identity ![cos(x+\frac{\pi }{2}) = (- sinx)](https://tex.z-dn.net/?f=cos%28x%2B%5Cfrac%7B%5Cpi%20%7D%7B2%7D%29%20%3D%20%28-%20sinx%29)
To prove any identity we always prove one side(either left hand side or right hand side) of the equation equal to the other side.
In this identity we take the left hand side first
![cos(x+\frac{\pi}{2})](https://tex.z-dn.net/?f=cos%28x%2B%5Cfrac%7B%5Cpi%7D%7B2%7D%29)
(as we know cos(a+b) = cosa×cosb-sina×sinb)
![= cosx\times0-sinx\times1](https://tex.z-dn.net/?f=%3D%20cosx%5Ctimes0-sinx%5Ctimes1)
![= 0-sinx](https://tex.z-dn.net/?f=%3D%200-sinx)
= - sinx ( Right hand side)
Hence identity is proved.
