Answer:

Potential Energy = 8550 Joules

Step-by-step explanation:

The potential energy of the body is the energy possessed by it due to its position therefore:

Potential energy = mgh

m = mass of the body measured in kg

g= acceleration due to gravity

h= height or distance measured in meters

But in the question asked we are not given mass but weight so

w= mg   measured in newtons

We have

w= 190 N

h= 45m

PE= mgh

PE  = w h= 190 * 45 =  8550 J

The unit of energy is Joule.

Out of a salary of $4500. I kept 1/3 as saving. Out of the remaining money. I spend 50% on food and 20% on house rent. How much
Step2247 [10]
Well 1/3 for savings means that you save 1/3*4500 or 1500 dollars.
You then have $3000 left. Of this if you spend 50% on food, you spend 0.5*3000 or 1500 dollars on food.

Answer:

The coordinates of his position is (-6,-8).

Step-by-step explanation:

Consider the provided information.

Let's assume for a moment that we are standing at the origin and the positive y-axis points due North while the positive x-axis points due East.

North represents the positive y axis, then south will represents the negative y axis.

It is given that the east represents the positive x axis then west represents the negative x axis.

Sasquatch-o-meter tells us that Sasquatch is 6 miles West and 8 miles South of our current position.

6 miles west represents a x=-6 and also 8 miles south represents y=-8

Thus, the coordinates of his position is (-6,-8).

Find (r-s) (t-s) + (s-r) (s-t) for all numbers r, s, and t. (a) 0 (b) 2 (c) 2rt (d) 2(s-r) (t-s) (e) 2(r-s) (t-s)
lyudmila [28]
Notice that the 2 expressions have 2 common terms.

(r-s) is just (s-r) times (-1)

similarly

(t-s) is just (s-t) times (-1)

this means that :

(r-s) (t-s) + (s-r) (s-t)=-(s-r)[-(s-t)]+(s-r) (s-t)

the 2 minuses in the first multiplication cancel each other so we have:

-(s-r)[-(s-t)]+(s-r) (s-t)=(s-r) (s-t)+(s-r) (s-t)=2(s-r) (s-t)
