Answer:
Step-by-step explanation:
A geometric sequence is a sequence such that any element after the first is obtained by multiplying the preceding element by a constant called the common ratio which is denoted by r. The common ratio (r) is obtained by dividing any term by the preceding term.
from the given expression
the given data are
first term a1= 
second term a2= 
third term a3= 
the common ratio is expressed as 
= 
Sum of Terms in a Geometric Progression
Finding the sum of terms in a geometric progression is easily obtained by applying the formulas:
nth partial sum of a geometric sequence substituting the values of a1=a and the common ratio= r we have

Step-by-step explanation:
So if 25 - x items are sold, and they each cost x, we can write an equation for the revenue to be
y = (25 - x)x
The vertex of this equation will represent the maximum revenue. So we need to write this equation in vertex form so we can find the vertex.
Vertex from is
y = a(x - h)^2+ k,
where (h,k) represent the vertex.
the vertex form of this equation would be
And the vertex would be
This means the maximum revenue will occur when x = 25/2

The value of c in the parallelogram is 45
<h3>How to determine the value of c?</h3>
From the question, we have the following parameters:
- Parallelogram PARL is similar to parallelogram WXYZ.
- AP = 15, PL = 25, and WZ= 75
To calculate the value of c, we make use of the following equivalent ratio.
AP : PL = XW : WZ
Substitute the known values in the above equation
15 : 25 = c : 75
Express the above equivalent ratio as fractions
15/25 = c/75
Multiply both sides of the equation by 75
75 * 15/25 = c/75 * 75
Evaluate the product
75 * 15/25 = c
Evaluate the product
1125/25 = c
Evaluate the quotient
45 = c
Rewrite the equation as
c = 45
Hence, the value of c in the parallelogram is 45

Answer:
35 people
Step-by-step explanation:
This means we have to do 420/12, or 70/2. This is 35, so there are 35 people on each bus.
