Answer:
Dy/dt = 11.67 ft/s
Step-by-step explanation: See Annex
In Annex, Triangles ACE and BCD are similar then, we can write
( y- x ) / y = 6 / 15
15*y -15*x = 6*y
15*y - 6*y = 15*x
9*y = 15*x
y = (15/9)*x
Differentiating with respect time on both sides of the equation we get
Dy/dt = (15/9) Dx/dt (1)
Where we know Dx/dt = 7 ft/s, and according to (1) Dy/dt does not depend on x (distance between man and the pole, only depend on the speed f the man
Dy/dt = (15/9) * 7
Dy/dt = 11.67 ft/s
Answer:
it will be approximately 10 weeks
Step-by-step explanation:
Answer:
Option A.
Step-by-step explanation:
step 1
we know that
The equation of the solid line is
The solution is the shaded area above the solid line
so
The equation of the first inequality is
step 2
The equation of the dashed line is
The solution is the shaded area above the dashed line
so
The equation of the second inequality is
therefore
The system of inequalities could be
