Hello.

The answer is: The Commutative property

The Commutative property states that order does not matter. Multiplication and addition are commutative. Commutative is also when you change the order of the equation but its still that same answer.

Have a nice day.

The kinetic energy k of an object in joules is given by the formula k = 1 mv2, where m is the object's mass in kilograms and v i

RideAnS [48]

Answer:

108,000 joules

Step-by-step explanation:

Kinetic energy, k = 1/2 mv^2

Where,

m = mass of the object in kilogram

v = velocity in meters per seconds

Velocity of an object = 20 meters per seconds

Kinetic energy = 48,000 joules

Solve for m

k = 1/2 mv^2

48,000 = 1/2 × m × 20^2

48,000 = 1/2 × m × 400

48,000 = 200m

m = 48,000 / 200

m = 240 kg

If it speeds up to 30 meters per second, then what is its new kinetic energy?

k = 1/2 mv^2

Using m = 240 kg

k = 1/2 mv^2

= 1/2 × 240 × 30^2

= 1/2 × 240 × 900

= 216,000 / 2

= 108,000 joules

The new kinetic energy = 108,000 joules

The expression 2/ +2w is used to find the perimeter of a rectangle with length / and width w what is the perimeter of a rectangl

levacccp [35]

perimeter = 2 l + 2w

here l = 15 and w = 4

perimeter = ( 2 × 15 ) + ( 2 × 4 ) = 30 + 8 = 38cm

Find the length of a missing side of the triangle around your nearest tenth

Allisa [31]

Using the Pythagorean theorem:

14^2 = 8^2 + x^2

196 = 64 + x^2

Subtract 64 from both sides:

132 = x^2

Take the square root of both sides:

X = 11.49

Rounded to nearest tenth = 11.5
