10
Because if you do 5•2 you get 10
More in depth explanation:
Though there are 25 possible configurations the question asks for two different toppings together. It also asks for unique combinations. So AB and BA are the same combination in this context. The only unique possibilities are
AB
AC
AD
AE
BC
BD
BE
CD
CE
DE
It is easy to simplify this into 5•2 for this situation. And if the question asked for three toppings you would do 5•3.
However if the question asked for the configurations for two toppings then you would do 5•5 and if it asked for the configurations of 3 toppings you would do 5•5•5
Volume of a sphere of radius r is
V = (4/3)πr³
r = 9
V = (4/3)π(9³) = 12(9²)π = 972 π
Answer : 972π cubic units
Answer:
Step-by-step explanation:
meants when 
, that the value for 
is 5.
So this gives us this equation:
meants when 
, that the value for is 10.
So this gives us this equation:
So I take equation 2 and divide it be equation 1 I get:
Simplifying:
Since the base for an exponential function can't be negative then 
.
So plugging into one of my equations I began with gives me an equation to solve for the initial value,
:
Divide both sides by 2:
The function is:
