Answer:
u•u = 17
u•v = 13
v•u = u•v = 17
v•u/u•u = 13/17
Step-by-step explanation:
Given 2 column matrices
u = [-1 4] and v = [7 5]
Note that when computing product, we will multiply component wise.
To compute u times u, we will take the dot product of both column matrix.
u•u = [-1 4] • [-1 4]
u•u = (-1)(-1) + (4)(4)
u•u = 1+16
u•u = 17
To compute u times v, we will take the dot product of column matrix u and column matrix v.
u•v = [-1 4] • [7 5]
u•v = (-1)(7) + (4)(5)
u•v = -7+20
u•v = 13
v•u/u•u can be gotten by simply substituting the resulting values.
v•u/u•u = 13/17
Answer:
6y+15
Step-by-step explanation:
Product is multiplication so write 6y. Increased means to add so write +15. Now combine into 6y+15.
Answer:
Step-by-step explanation:
Answer:6.5
To find the mean (average)
Add 3.5 and 9.5 which equals 13. Then you divide 13 by 2 because you added two numbers (3.5 and 9.5) which equals 6.5.
