Answer:

Step-by-step explanation:

The potential energy of a body can be found by using the formula

PE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 9.8 m/s²

We have

PE = 500 × 9.8 × 4

We have the final answer as

Hope this helps you

For a line that goes through points (2,-2) and (1.-6), what is the equation

sesenic [268]

Answer:

$y + 6 = 4[x - 1]\:or\:y + 2 = 4[x - 2]$

Step-by-step explanation:

First find the <em>rate of</em><em> </em><em>change</em><em> </em>[<em>slope</em>]:

$\frac{-y_1 + y_2}{-x_1 + x_2} = m$

$\frac{2 - 6}{-2 + 1} = \frac{-4}{-1} = 4$

Then plug each of these coordinates into the Point-Slope Formula, $y - y_1 = m[x - x_1].$ Now remember, in this formula, all the negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL inserting the coordinates into the formula with their CORRECT SIGNS:

$y + 6 = 4[x - 1]\:or\:y + 2 = 4[x - 2]$

Answer: so a can be -2 and b can be 6, note that there are many combinations since u can factor all types of stuff out including fractions

Step-by-step explanation:

a(bx+3) basically is just factoring out a random common factor between -12x and -18

so we can factor out a -2 to get -2(6x+9)
