Answer:
1,6 ,15,20,15,6,1
Step-by-step explanation:
The trick here is that the expansion are the
numbers in pascal triangle
1
1,1
1,2,1
1,3,3,1
1,4,6,41,
1,5 ,10, 10, 5, 1
1,6 ,15,20,15,6,1
For this case we must solve the following quadratic equation:
We must apply the following formula:
We have to:
Substituting we have:
Thus, the solutions are:

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
the given expression is,
5x - (x +1) = 5 - 2x
5x - x - 1 = 5 -2x
4x + 2x = 5+1
6x = 6
x = 6/6
x = 1
thus, the answer is x = 1
Answer:
P425
Step-by-step explanation:
Given data
We are given that the family exchanged
$250 for P4250
the rate is
$250 for P4250
$1 will be x
x= 4250/250
x= P17
the pesos equivalent of $25 will be
= 25*17
= P425
