Answer:
r=2.9cm
Step-by-step explanation:
we know the formula, mass= density*volume
as a result we can figure out the volume = mass/density
=485/8 cm^3
=60.625cm^3
here comes another formula of volume of cone =
we will use this to find the radius,
=60.625
=181.875
h is 70mm which we will turn to 7cm
*7=181.875
=8.27
r=2.875825cm
r=2.9cm
nice question. hope this helps
Answer:
y = - 4x - 2 is the required equation of the line.
Step-by-step explanation:
Equation of two parallel lines differ only by a constant.
If the equation of a line is then the equation of the line parallel to it is given by
.
Note that only the constants differ in both the equations.
The given equation is: y = - 4x - 2
This is equivalent to 4x + y + 2 = 0.
Therefore, the equation of the line parallel to the given line will be:
4x + y + k = 0.
We are also given the point which passes through the line. We can substitute it to determine the value of 'k'.
Substituting (- 2, 6), we get:
4(-2) + 6 + k = 0
⇒ - 8 + 6 + k = 0
⇒ k = 2
Hence, the equation of the required line is: y = - 4x - 2
