10 cars in each row
5 cars x 6 rows = 30
30 divided by 3 = 10 cars in each row
1 and a fourth because 3 3/4 devided by three equals 1 1/4
The magnitude of the vector is √(7^2+12^2)=√(49+144)=√193
The direction is α=arctan(y/x)=arctan(12/-7)≈-59.74 however this is relative to the negative x-axis so we add 180° to get the standard angle...180-59.74=120.26°
So the vector is √193 @ 120.26°
It is hard to see but the first one is 243xy^6/5
The one that best applies here is the b option: The range only includes numbers greater than or equal to 0. This is because<span> when you square a number that is negative or positive, it becomes a positive</span>
