Answer:
≈ 4,22 m
Step-by-step explanation:
volume = 20000L = 20000 dm^3 = 20 m^3
diameter = 2,4m
the volume of a cilinder is π * r^2 * h (height)
20 = π * 1,2^2 * h
h = ≈ 4,42 m

Answer:
y = - x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x + 9 ← is in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= -
, thus
y = - x + c ← is the partial equation
To find c substitute (- 6, 5) into the partial equation
5 = 9 + c ⇒ c = 5 - 9 = - 4
y = - x - 4 ← equation of perpendicular line
