In this case, it's clear that 5 is half of ten, therefore, you have to divide the first equation in half, giving you 5x42= 210. If it was something such as 20x24, you just work the answer from the multiple of ten.
Hope this helpsn
The answer is c cause it is the only one that rotated
Answer:
√1394
Step-by-step explanation:
The resultant vector is the specified sum of the component vectors.
v - 5u = <-7-5(-4), 5-5·8> = <13, -35>
The magnitude of the result is the root of the sum of the squares of the components.
║v -5u║ = √(13² +(-35)²) = √1394
Answer:
-1/3
Step-by-step explanation:
The slope of the line has the form y = mx + b where m is the slope. Here the slope is m = 3. A line perpendicular to it will have a negative reciprocal slope. The negative reciprocal of 3 is -1/3.
