Answer:
hello :
note :
the nth term of an arithmetic sequence is :
An =A1+(n-1)d ....a common difference is : d ... A1 : the first term
in this exercice : A1 = - 1 d = (-6) -(- 1) = -5
An = - 1 + (n - 1)(-5)
the expression is : An = - 5n +4
Answer:
hope it works for u
Step-by-step explanation:
Given the length of the rectangle = l
the breadth of the rectangle = b
perimeter of the rectangle = sum of length of all sides of the rectangle
= l+ b+ l+ b
=2 l+2 b
=2( l+ b)
∴ perimeter of the rectangle =2( l+ b)
as given perimeter = 1004 m
hence ,
2(l+ b)= 1004
(l+ b)=1004/2 = 502 m
<h2>
l+ b=502 m</h2>
Cos( A + B ) = cosAcosB - sinAsinB ;
cos( A + B ) / ( cosAsinB ) = ( cosAcosB - sinAsinB ) / ( cosAsinB ) = ( cosAcosB ) / ( cosAsinB ) - ( sinAsinB ) / ( cosAsinB ) = cosB / sinB - sinA / cosA = cotB - tanA ;
