Slope intercept form of a line perpendicular to 3x + y = -8, and passing through (-3,1) is
<u>Solution:</u>
Need to write equation of line perpendicular to 3x+y = -8 and passes through the point (-3,1).
Generic slope intercept form of a line is given by y = mx + c
where m = slope of the line.
Let's first find slope intercept form of 3x + y = -8
3x + y = -8
=> y = -3x - 8
On comparing above slope intercept form of given equation with generic slope intercept form y = mx + c , we can say that for line 3x + y = -8 , slope m = -3
And as the line passing through (-3,1) and is perpendicular to 3x + y = -8, product of slopes of two line will be -1 as lies are perpendicular.
Let required slope = x
So we need to find the equation of a line whose slope is and passing through (-3,1)
Equation of line passing through and having lope of m is given by
Substituting the values we get,
Hence the required equation of line is found using slope intercept form
Step-by-step explanation:
Formula that relates the mass of an object at rest and its mass when it is moving at a speed v:
Where :
m = mass of the oebjct in motion
= mass of the object when at rest
v = velocity of a moving object
c = speed of the light =
We have :
1) Mass of the Dave =
Velocity of Dave ,v= 90% of speed of light = 0.90c
Mass of the Dave when moving at 90% of the speed of light:
m = 151.41 kg
Mass of Dave when when moving at 90% of the speed of light is 151.41 kg.
2) Velocity of Dave ,v= 99% of speed of light = 0.99c
Mass of the Dave when moving at 99% of the speed of light:
m = 467.86 kg
Mass of Dave when when moving at 99% of the speed of light is 467.86 kg.
3) Velocity of Dave ,v= 99.9% of speed of light = 0.999c
Mass of the Dave when moving at 99.9% of the speed of light:
m = 1,467.17 kg
Mass of Dave when when moving at 99.9% of the speed of light is 1,467.17 kg.
4) Mass of the Dave =
Velocity of Dave,v=?
Mass of the Dave when moving at v speed of light: 500
Dave should be moving at speed of .
