Which transformation rule below translate points 5 units to the left and 2 units up? *

(1 Point)

(x y) --> (x + 5, y + 2)

(x, y) --> (x - 5. y - 2)

(x, y) --> (x + 5. y - 2)

(x, y)--> (x - 5. y + 2)

Please I need help

Answers

Answer:

(x, y)--> (x - 5. y + 2)

Step-by-step explanation:

Given the coordinate (x, y), when transforming the coordinate, up and right, the value of the constant we are using must be added to the coordinate since positive x axis acts towards the right side and the positive y axis acts upwards.

Also, when transforming the coordinate down and left, the value of the constant we are using must be subtracted from the coordinate since negative x axis acts towards the left side and the negative y axis acts downwards.

According to the question, we are to translate the coordinate (x, y) 5 units to the left and 2 units up,

Translating 5 units to the left means the x coordinate will become x--> (x-5)

Translating 2 units up means the y coordinate will become x--> (x+2)

Hence the correct transformation rule will be (x, y)--> (x - 5. y + 2)

A 52kg person walks from the ground to the roof of 78.52m tall building. How much gravitational potential energy is there?​USE GRESA METHOD

Answers

Answer:

P = 40013.792 J

Step-by-step explanation:

Given that,

Mass of a person, m = 52 kg

The height of the building, h = 78.52 m

We need to find the gravitational potential energy at this point. It is given by the formula as follows :

P = mgh

Where g is acceleration due to gravity

P = 52 kg × 9.8 m/s² × 78.52 m

P = 40013.792 J

So, the gravitational potential energy is 40013.792 J.
