Assuming the logarithm is base
, you have
Answer:
30/(2x^2-x)
Step-by-step explanation:
5/(2x-1) * 6/x
Multiply the numerators
5*6 = 30
Multiply the denominatos
(2x-1) *x = 2x^2 -x
5/(2x-1) * 6/x = 30/x(2x-1) = 30/(2x^2-x)
Answer:
3^2
Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
(a^b)/(a^c) = a^(b-c)

Answer:
<h2> $9</h2>
Step-by-step explanation:
<h2>
f(x) = - 25 ( x - 9 )² + 200</h2>
<em>when</em><em> </em>x = 5 ,
f(5) = - 25 ( 5 - 9 )² + 200 = - 200
<em>when</em><em> </em>x = 9 ,
f(9) = - 25 ( 9 - 9 )² + 200 = 200
<em>when </em>x = 10 ,
f(10) = - 25 ( 10 - 9 )² + 200 = 175
<em>when</em><em> </em>x = 15 ,
f(15) = - 25 ( 15 - 9 )² + 200 = -700
∴ when <u>price = $9</u>
the company receive the maximum profit
