Answer:
[tex]\sqrt{135\\}[/tex]
Step-by-step explanation:
Geometric mean can be calculated like such:
a/x = x/b
Where a and b are your 2 numbers. By solving for x by cross-multiplying you get:
x^2=ab
So to solve for geometric mean, all you have to do is to multiply the two numbers and take the square root:
9(15)=135
[tex]\sqrt{135\\}[/tex]
The geometric mean of 9 and 15 is 11.62
Given two integers A and B, the geometric mean of the integers is expressed as:
GM = √A×B
Given the values 9 and 15, the geometric mean of the values is expressed as:
GM = √9×15
GM = √135
GM = 11.62
Hence the geometric mean of 9 and 15 is 11.62

(x - 1) is a factor of the following, what are the remaining 2 factors:
Answer:
(x +(-2) ) and ( x+3)
The factors of a given cubic polynomial function are
( x-1) (x -2 ) and (x +3)
Step-by-step explanation:
Step(i):-
Given that x³ - 7x + 6=0
f(x) = x³ - 7x + 6=0
put x=1
f(1) = 1 -7 +6 =0
(x -1 ) is one factor of given polynomial
By using synthetic division
x³ x² x constant
x=1 ║ 1 0 -7 6
║ 0 1 1 -6
1 1 -6 0
The polynomial ( x² + x - 6) =0
Step(ii):-
The factors of
x² + x - 6=0
x² + 3x -2x - 6=0
x ( x +3 ) - 2( x +3) =0
(x -2 ) ( x+3 ) =0
x = 2 and x =-3
Final answer:-
The factors of a given cubic polynomial function are
( x-1) (x -2 ) and (x +3)

A principal of $2600 is invested at 7% interest, compounded annually. How much will the investment be worth after 13 years?
Use the calculator provided and round your answer to the nearest dollar.
Answer:
The total amount accrued, principal plus interest, from compound interest on an original principal of $ 2600 at a rate of 7% per year compounded 1 time per year over 13 years is $ 6266.
Step-by-step explanation:
Given
Principle P = $2600
Interest rate r = 7% = 0.07
Time period t = 13 years
Compounded annually means: n = 1
To determine
Accrued Amount = ?
Using the formula
[tex]A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{nt}[/tex]
substituting P = 2600, r = 0.07, t = 13, n = 1
[tex]A\:=\:2600\left(1\:+\:\frac{0.07}{1}\right)^{1\left(13\right)}[/tex]
[tex]A=2600\left(1+0.07\right)^{1\cdot \:13}[/tex]
[tex]A = 6266[/tex] $
Therefore, the total amount accrued, principal plus interest, from compound interest on an original principal of $ 2600 at a rate of 7% per year compounded 1 time per year over 13 years is $ 6266.

An airline finds that if it prices a cross-country ticket at $400, it will sell 300 tickets per day. It estimates that each $10 price reduction will result in 30 more tickets sold per day. Find the ticket price (and the number of tickets sold) that will maximize the airline's revenue.
Answer:
$300, 400 tickets
Step-by-step explanation:
let x= number of price reduction
let us solve for p(x), the price per ticket with x reductions
p(x)= 400-10x dollars
Also, q(x), the number of tickets sold with x reduction
q(x)=300+10x tickets
we know that revenue
R(x)= p(x)*q(x)
substitute
R(x)= (400-10x)*(300+10x)
open bracket we have
R(x)= 120000+4000x-3000x-100x^2
R(x)=120000+1000x-100x^2
R(x)'= 1000-100x
R(x)'=0
1000=100x
x=10
R(x)"=-100
R(x)"<0
x= 10 is the maximum
from
p(x)= 400-10x
p(x)= 400-10*10
p(x)= 400-100
p(x)= $300
q(x)=300+10x tickets
q(x)=300+10*10
q(x)=300+100
q(x)=400 tickets
