Answer:
Step-by-step explanation:
× = × = ( Domain is x ≠ 1 and x ≠ 5 )
The expression has an excluded value of x = 5
Answer:
30
Step-by-step explanation:
4.50=15%
30=100%
check;
30*0.85=25.5
30-25.5=4.50
Area of a trapezoid = h/2 ( a + b) where h = height and a and b are the lengths of the 2 parallel sides.
So here we have
Area = 12/2 ( 18 + 23)
= 246 in^2 Answer
ii . volume of a sphere = 4/3 pi r^3 so
1436.03 = 4/3 pi r^3
r^3 = 1436.03 / (4/3 * pi) = 342.827
r = cube root of 342.827 = 7.0 m Answer
Answer:
Differential equation will be
Step-by-step explanation:
Let V is the volume of the raindrop and surface area of the drop is S.
Since volume of the raindrop reduces at the rate directly proportional to the surface area.
Or where k is the proportionality constant.
We know volume of the spherical drop V =
Since S =
Therefore,
Since coefficient of is a constant.
Then
Therefore, differential equation for the volume of the raindrop as function of time will be
