This problem involves the dot product.
You must provide all info for position vector m. Your (2,) is inadequate.
Supposing that the terminal point of vector m were (2,3), then
m dot n would equal 8, or 8 = 2*2+3*y. Then 8 = 4 + 3y, and 4 = 3y, and y =3/4.
Please type in the terminal point of vector m and then answer this question following the above example.
Answer:
Step-by-step explanation:
With the expression 
, start by looking to see if you can take out any x-values. As you can see, both 
and 
have an x to the first power. You can factor that out, leaving you with the expression 
. Now you look for the largest numerical value that you can take out. Both 4 and 16 are divisible by 4, so you can factor out the number 4, leaving you with the expression .
Answer:
Speed of passenger train=18+30=48 mph
Speed of freight train=30 mph
Step-by-step explanation:
Let x be the speed of freight train.
Speed of passenger train=x+18 mph
Time taken by freight train=1.5+2.5=4 hrs
Time taken by passenger train to overtake the freight train=2.5 hrs
Distance=
By using this formula
Distance traveled by passenger train=2.5(x+18) miles
Distance traveled freight train=4x
According to question
Speed of freight train=30 mph
Speed of passenger train=18+30=48 mph
Can you take a picture of it
Answer:
Step-by-step explanation:The formal term to describe a straight line graph is linear, whether or not it goes through the origin, and the relationship between the two variables is called a linear relationship. Similarly, the relationship shown by a curved graph is called non-linear.
