Answer:

0.1(2, 6) = (0.2, 0.6)

Step-by-step explanation:

The projection of B onto A will be ...

|B|·cos(θ)×uA

where uA = A/|A|, a unit vector in the A direction.

The dot product of A and B is ...

A•B = |A|·|B|·cos(θ), so the desired vector is ...

projection of B onto A = (A•B)/|A|·(A/|A|) = A·(A•B)/|A|²

For A = (2,6) and B = (5, -1), this is ...

projection of (5, -1) onto (2, 6) = (2, 6)·(2·5-6·1)/(2²+6²) = (2, 6)·4/40 = 0.1·(2, 6)

= (0.2, 0.6)

I WILL MARK AS BRAINLIEST! Solve the following
deff fn [24]

Answer:

6)

a. x=35

b. x=4

c. x=30

Step-by-step explanation:

6a) 7/9=x/45

7/9×45=x

7×45/9=x

315/9=x

35=x

x=35

————————

b. 10/8=5/x

5/4=5/x

5/4x=5(the x is in the middle of the division sign here)

5x/4=5(the x is NOT in the middle of the division sign)

5x=5×4

5x=20

x=20/5

x=4

———————

c. x/34=15/17

x=15/17×34

x=15×34/17

x=510/17

x=30

hope that helped you. I can't answer number 7, I'm sorry
