Answer:
question 3: n is bigger than or equal to 0
question 5: n is bigger than or equal to 0 (the same as question 3)
Step-by-step explanation:
solve the same way as a equation. just remember the symbols
Answer:
Total Area = 84 feet
Step-by-step explanation:
Triangle = 1/2 (3 × 4) = 12/2 = 6 ft
Rectangle 1 = 7 × 4 = 28 ft
Rectangle 2 = 5 × 10 = 50 ft
Total Area = 6ft + 28ft + 50ft = 84ft
Answer: hello some part of your question is missing
Let v=〈−2,5〉 in R^2,and let y=〈0,3,−2〉 in R^3.
Find a unit vector u in R^2 such that u is perpendicular to v. How many such vectors are there?
answer:
One(1) unit vector ( < 5/√29, 2 /√29 > ) perpendicular to 〈−2,5〉
Step-by-step explanation:
let
u = < x , y > ∈/R^2 be perpendicular to v = < -2, 5 > ------ ( 1 )
hence :
-2x + 5y = 0
-2x = -5y
x = 5/2 y
back to equation 1
u = < 5/2y, y >
∴ || u || = y/2 √29
∧
u = < 5 /2 y * 2 / y√29 , y*2 / y√29 >
= < 5/√29, 2 /√29 > ( unit vector perpendicular to < -2, 5 > )
