Answer:
First Option 
Step-by-step explanation:
To graphically add two vectors a and b using the -tail and tip-method, you must draw the tail of b at the tip of the vector a. Then you must draw a line that goes from the tail of a to the tip of b. This line represents the sum of 
.
In this problem, notice that the tail of the vector w is on the tip of the vector v. The line that joins the tail of v with the tip of w is u.
Therefore we can say that 
.
The answer is the first option
Answer:
10 times 16 = C
Step-by-step explanation:
c2 = a2 + b2 − 2ab cos C = 162 + 102 − 2(10)(16) cos 22°
From the Formula:
Distance = Sqr Root [ (x2- x1)^2 + (y2 - y1)^2 ]
Distance = Sqr Root [ (20 --15)^2 + 18 -18)^2 ]
Distance = Sqr Root [ 1,225 + 0]
Distance = 35
Reorder the terms: 6.25 + -5y + y^2 = -14 + 6.25
Combine like terms: -14 + 6.25 = -7.75 6.25 + -5y + y2 = -7.75
Factor a perfect square on the left side: (y + -2.5)(y + -2.5) = -7.75
Can't calculate square root of the right side (negative). The solution to this equation could not be determined.
Answer:
x=7
Step-by-step explanation:
In a parallelogram, you know that parallel sides are equal in length, therefore, x+4 must equal 5x-24. From there you solve for x.
x+4 = 5x-24
28 = 4x (subtract x from both sides and add 24 to both sides)
7=x (28 divided by 4 is 7).
