Answer:
x - 2y = 2
Step-by-step explanation:
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and A, B are integers )
given y = x - 1
multiply through by 2 to eliminate the fraction
2y = x - 2 ( subtract 2y from both sides )
0 = x - 2y - 2 ( add 2 to both sides )
x - 2y = 2 ← in standard form
Answer:
0.0048cm/s
Step-by-step explanation:
Volume of the spherical balloon is expressed as;
dV/dt = dV/dr * dr/dt
Given
dV/dt = 5cm³/s
dV/dr = 4πr²
Since V = 972picm³
972π = 4/3πr³
972 = 4/3r³
4r³ = 972 * 3
r³ = (972 *3)/4
r³ = 729
r = ∛729
r = 9cm
dV/dr = 4π(9)²
dV/dr = 324π
dV/dt = dV/dr * dr/dt
5 = 324πdr/dt
dr/dt = 5/324π
dr/dt = 5/324(3.14)
dr/dt = 5/1017.36
dr/dt = 0.0048cm/s
