Density=mass/volume
Your volume is 0.5*0.5*0.5, which is 0.125m^3, andd you have the density (i'm not sure if you typed 2.0*103 or 2.0*10^3).
Anyway, potential energy=mass*gravitational pull*height
So you need to find mass
Rearrange the density formula
Density=mass/volume
Density*volume=mass
Once you find the mass, multiply it by 9.81 (gravitational pull) and 3m (height) to find potential energy

LOOK AT CHART BEFORE THE BULLET PART:

Answer:

  • m = -3/4
  • y-intercept = 399
  • slope-intercept equation: y = -3/4x + 399

Step-by-step explanation:

It can be easiest simply to solve the equation for y.

  3x + 4y = 1596

  4y = -3x + 1596 . . . . subtract 3x

  y = -3/4x + 399 . . . . divide by 4

From this equation in slope-intercept form you can read the slope as -3/4 and the y-intercept as 399. You already know the equation.

FIRST TO ANSWER GETS BRAINLIEST! A, B, and C are polynomials, where A = n, B = 2n + 6, and C = n2 – 1. What is AB – C in simples
denis23 [38]

Answer:

n^2+6n+1

Step-by-step explanation:

AB would be (n) * (2n + 6). We need to distribute the n, so we multiply the n by each term within the parentheses and add those products together:

AB = n(2n+6)=2n^2+6n

C is just n^2-1 , and we subtract this from 2n^2+6n:

2n^2+6n-(n^2-1)=2n^2+6n-n^2+1=n^2+6n+1

Thus, the answer is n^2+6n+1.

Hope this helps!

A theater sells tickets for a concert . Tickets for lower level sells for $35 each , tickets for upper level sell for $25 each .
arlik [135]
150 lower level
200 upper level

Let x = lower level and y = upper level. You can then set up an equation for cost as:

35x + 25y = 10,250

and the equation for total tickets as:

x + y = 350. 

Solve using any method.
