Answer: cardiac output=11,250ml/min
Step-by-step explanation: Cardiac output = Heart rate(beats/min) × stokes volume (ml/beat)
Cardiac output = 125 ×(130 -40)
Cardiac output= 125×90 =11,250ml/min
B
calculate the slopes m of the 2 lines using the gradient formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = C(- 2, 4) and (x₂, y₂ ) = D(0, - 4 )
=
=
= - 4
repeat with (x₁, y₁ ) = F(- 4, 0 ) and (x₂, y₂ ) = G(4, 2 )
=
=
= 
The 2 lines are perpendicular because their slopes are negative reciprocals
