Answer:
Option A, 50 degrees
Step-by-step explanation:
<u>Step 1: Estimate this angle</u>
<em>Option A, works because looks about the size of 50 degrees</em>
Option B, doesn't work because it is not more than a right angle.
Option C, doesn't work because it is not an obtuse angle.
Option D, doesn't work because there is no way it is 15.
Answer: Option A, 50 degrees
Answer:
3.74637674E20
Step-by-step explanation:
Step 1: 3x + 4y = 15
Step 2: Get in Slope intercept form = y=mx+b
Step 3: Subtract 3x from both sides since your trying to get Y alone
Step 4: 4y = -3x + 15
Step 5: Divide 4 from both sides since 4 cannot go into -3 or 15 leave it as is
Step 6: Y =

+

Step 7: Point slope form= y-y=m(x-x)
Step 8: (8, -2) are your points 8x and -2y
Step 9: Substitute
Step 10: y - 2 =

(x - 8)
Step 11: Distribute
Step 12: y - 2 =

+ -6
Step 13: Add 2 to both sides
Answer : y =

+ 4
Answer:
Part 1)
Projection of vector A on vector B equals 19 units
Part 2)
Projection of vector B' on vector A' equals 35 units
Step-by-step explanation:
For 2 vectors A and B the projection of A on B is given by the vector dot product of vector A and B
Given

Similarly vector B is written as

Thus the vector dot product of the 2 vectors is obtained as

Part 2)
Given vector A' as

Similarly vector B' is written as

Thus the vector dot product of the 2 vectors is obtained as
