tis a little of plain differentiation.
we know the radius of the cone is decreasing at 10 mtr/mins, or namely dr/dt = -10, decreasing, meaning is negative.
we know the volume is decreasing at a rate of 1346 mtr/mins or namely dV/dt = -1346, also negative.
so, when h = 9 and V = 307, what is dh/dt in essence.
we'll be needing the "r" value at that instant, so let's get it
now let's get the derivative of the volume of the cone
Answer:
a
b
c
Step-by-step explanation:
Generally the size of the sample sample space is mathematically represented as
Where N is the total number of objects available and r is the number of objects to be selected
So for a, where N = 19 and r = 8
For b Where N = 25 and r = 3
For c Where N = 23 and r = 2
