Cos( A + B ) = cosAcosB - sinAsinB ;
cos( A + B ) / ( cosAsinB ) = ( cosAcosB - sinAsinB ) / ( cosAsinB ) = ( cosAcosB ) / ( cosAsinB ) - ( sinAsinB ) / ( cosAsinB ) = cosB / sinB - sinA / cosA = cotB - tanA ;
Multiply 1/5 and 26/1 across the top and bottom, and you get 26/5
From there, you can estimate that its a little more than 5 because you know that 25/5 is 5 and 26/5 should be a tiny bit greater.
Hope this helped!
What are the number or what is the equation.What amount of dollars
Answer:
-1280
Step-by-step explanation:
Given a₁ = -10, n = 8, r =2
Required to find nᵗʰ term.
From the general formula: aₙ= a₁ (r)ⁿ⁻¹
Therefore nᵗʰ = -10(2)⁸⁻¹
= -10(2)⁷
= - 10(128)
= - 1280
Answer: Slope is m = 2/3
Step-by-step explanation:
-You have exactly four points on a table:
-Use the slope formula and use any two points from those four points in order to find the slope:
-The two points I use are 
and 
for the equation:
So, the slope of the table is 
.
