Is it possible to square root a negative number?

<span>No because a negative times a negative will be positive and it will not equal a negative number. the square root cannot be one negative and one positive because that is against the definition of a square root.

No because you had no number which were negative after you squared. if you do every number goes back positive after you squared it i think.

Answer:

Perimeter: 2(3x+6)+ 2(2x-4)

X=9

Step-by-step explanation:

In order to create the expression you just have to remember that the perimeter of a rectangle equals 2 bases plus 2 sides, so the expression would be:

Perimeter: 2(heights)+ 2(bases)

Perimeter: 2(3x+6)+ 2(2x-4)

IN order to solve for X we just have to insert the value of perimeter, which is 94:

Perimeter: 2(3x+6)+ 2(2x-4)

94=2(3x+6)+ 2(2x-4)

94= 6x+12+4x-8

94=10x+4

94-4=10x

x=90/10

x=9

So the value of x would be 9.

Answer:

Vel_jet_r = (464.645 mph) North + (35.35 mph) East

||Vel_jet_r|| = 465.993 mph

Step-by-step explanation:

We need to decompose the velocity of the wind into a component that can be added (or subtracted from the velocity of the jet)

The velocity of the jet

500 mph North

Velocity of the wind

50 mph SouthEast = 50 cos(45) East + 50 sin (45) South

South = - North

Vel_ wind = 50 cos(45) mph East - 50 sin (45) mph North

Vel _wind = 35.35 mph East - 35.35 mph North

This means that the resulting velocity of the jet is equal to

Vel_jet_r = (500 mph - 35.35 mph) North + 35.35 mph East

Vel_jet_r = (464.645 mph) North + (35.35 mph) East

An the jet has a magnitude velocity of

||Vel_jet_r|| = sqrt ((464.645 mph)^2 + (35.35 mph)^2)

||Vel_jet_r|| = 465.993 mph
