Answer:

2√5

Step-by-step explanation:

Using the formula for calculating resultant

R = √Fx + Fy

\sum Fx = -2sin 45 + 4 cos 45

\sum Fx =  2cos45

\sum Fx = 2(1/√2)

\sum Fx   = 2/√2

Similarly;

\sum Fy = 2 cos 45 + 4 sin45

\sum Fx  = 2(1/√2) + 4(1/√2)

\sum Fx = 6/√2

Magnitude = √(2/√2)²+6/√2)²

Magnitude = √4/2 + 36/2

Magnitude = √2+18

Magnitude = √20

Magnitude = 2√5

Hence the magnitude of their sum is 2√5

Which of the following is a logical conclusion to the conditional statements
stellarik [79]

Answer:

A

Step-by-step explanation:

If I text him now, then I will catch him before he gets home.

If I catch him before he gets home, then he will meet me in

time.

If a then b, If b then c

Combine both conditional statements by cancelling out the middle man, which is "I will catch him before he gets home."

So you get, "If i text him now, he will meet me in time"

Please help
riadik2000 [5.3K]

Answer: they lost 16 games

<u>Step-by-step explanation:</u>

Wins: x + 17

Losses: x

Ties: 3

Total: 52


Wins + Losses + Ties = Total

x + 17 +    x      +     3   =    52

                     2x + 20 = 52

                     2x          = 32

                      x            = 16
