Answer
L= 3 W=7
Step-by-step explanation:
22.75 - 3.25 = 19.5 He earned 19.5$ by selling both water and lemonade. Lemonade cost 3$ each so 3x3=9. Water cost 1.5$ each so 1.5x7=10.5. 10.5+9=19.5.

With
the singular ODE can be written as
The first term of the second series admits the indicial equation. When
, we have
Factoring reveals two distinct roots at

Next, shift the index of the first sum so that it starts at
by replacing
, then consolidate the sums to get
Setting
, we then have this as
However I don't see the connection to the given answer... It seems some information is missing, specifically about how the coefficients
are related.
When a perpendicular is dropped from the right-angle (C) to the opposite side AB, the metric relations apply:
BD*BA=a^2 ..........................(1)
AD*AB=b^2...........................(2)
BD*DA=DC^2........................(3)
Given AD=6, AB=24, using metric relation (2) above, we have
b^2=6*24=144
=>
b=sqrt(144)=12
By the way, we conclude that this is a 30-60-90 triangle because b/AB=(1/2)=sin(B) => B=30 degrees.
Answer: b=12
a geometric sequence is a bunch of numbers where you can get from a number to the next number by multiplying the previous number by a certain number
might be confusing so here's an example
1,2,4,8,16
each term is multiplied by 2 to get next term, that number that each term is multiplied by is called the common ratio
formula for geometric sequence is
where is nth term
is first term
r is teh common ratio
n=which term
in our example
1,3, 9, 27, 81
each term is being multiplied by 3 so it is a geometric sequence and thus r=3
also first term is 1 so
so the formula is or in function notation
