Answer:
area of field = 146.24 m²
Step-by-step explanation:
Total area of field = I + II + III
Total area of field = 64 + 32 + 50.24
Total area of field = 146.24 m²
Answer:
Nicole is correct
Step-by-step explanation:
by multiplying the first equation by 3 it becomes:
3x + 6y =21
this can cancel the -3x in the second equation when adding them together
Answer:
-17.5 degrees Celsius in 5 hours
Step-by-step explanation:
0(current temp)-3.5x(temp decrease)=5(hours)
then simplify
Answer:
The volume is increasing at a rate of 1508 cubic millimeters per second when the diameter is 60 mm.
Step-by-step explanation:
Volume of a sphere:
The volume of a sphere is given by the following equation:

In which r is the radius.
Implicit derivatives:
This question is solving by implicit derivatives. We derivate V and r, implicitly as function of t. So

The radius of a sphere is increasing at a rate of 4 mm/s.
This means that 
How fast is the volume increasing (in mm^3/s) when the diameter is 60 mm?
This is
when
. So



The volume is increasing at a rate of 1508 cubic millimeters per second when the diameter is 60 mm.
