Answer:
If you've learnt sin(A+B) = sinAcosB + cosAsinB,
sin(4u)
= sin(2u+2u)
= sin(2u)cos(2u) + cos(2u)sin(2u)
= 2 sin(2u) cos(2u).
Answer:
The coefficient is "12"
Step-by-step explanation:
Step 1: Encircle the variable along with its power whose coefficient we are finding.
Step 2: Leave that variable and consider all other numbers or variables written with it. That will be the coefficient.
Answer:
2/5
Step-by-step explanation:
Slope can be found with rise over run. So looking at the graph, the line rises 2 units and runs 5 units to the right. Therefore, the slope should be 2/5.
Answer:
D. There are infinitely many solutions
Step-by-step explanation:
Solving the second equation for y gives you the first equation. This is a dependent system. Any solution of one equation is also a solution to the other one. There are infinitely many solutions.
