Answer: 2(2x+4y)
Step-by-step explanation:
4(x+2y) would be simplified to 4x+8y, so you just have to make an expression that would get you that answer.
Unit vector along the direction v = <3,1,-4> is :
So, unit vector opposing the is :
so, vector of magnitude 3 units in opposite direction from v is :
Hence, this is the required solution.
Answer:
In naming a ray, we always begin with the letter of the endpoint (where the ray starts) followed by another point on the ray in the direction it travels. Since the vertex of the angle is the endpoint of each ray and our vertex is , each of our rays must begin with . Only fails to do so.
SO first you want to change it to Y=mX+b by getting the y by itself. Subtract 3x over and have -6y=-3x=12 divide both sides by -6 and have y=1/2x-2. To get the perpendicular slope you flip it 1/2 to 2 then change its sign 2 to -2
The new slope is -2
Unknown side = square root (100 - 49)
unknown side = square root (51)
unknown side = 7.14
