Step-by-step explanation:
since the two lines are parallel, slope of the line is Sam so it's 3.
let eqn of the line be y = 3x + b.
sub (4, -2):
4 = 3(-2) + b
b = 10
therefore, equation of the line is y = 3x + 10

♥ Solve:
(Arjun) 40*30=1200
(Dalia) 55*30=1650
Now subtract
1650-1200=450.
That means that Dalia will type 450 minutes more.
Final answer: 450
The volume of the sphere is expressed in the formula V = 4/3 pi r^3. The rate of change of volume is determined by differentiating the formula: dV/dt = 4pi r^2 dr/dt. When we substitute 500 cm3/min as dV/dt and 30 cm as r. Then dr/dt is equal to 0.0442 cm/min
