Answer:
What is the answer choices
Answer: sum of all the given three sides
The angle between u = (-2,-5) and v = (5,2) is 134 degrees approximately.
<u>Solution:</u>
Given, two vectors are u = (-2, -5) and v = (5, 2)
We have to find the angle between two vectors.
We know that,

where
is angle between vectors a and b




Hence, the angle between given two vectors is 134 degrees approximately.
Answer:
y=1/4x
Step-by-step explanation:
y=mx+b
m=1/4
so, y=1/4x+b
Now, look at our line's equation so far: . b is what we want, the 1/4 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (4,1).
So, why not plug in for x the number 4 and for y the number 1? This will allow us to solve for b for the particular line that passes through the point you gave!.
(4,1). y=mx+b or 1=1/4 × 4+b, or solving for b: b=1-(1/4)(4). b=0.
y=1/4x+0
The difference would be 74.059
