Answer:
The answer is B.
Step-by-step explanation:
12 ≤ r + 22
r + 22 ≥ 12
r + 22 − 22 ≥ 12 − 22
r ≥ −10
I hope this helps you :D
Answer:
25
Step-by-step explanation:
I added them
Use the sum of angles's trigonometric identity formula:
cos(A+B)=(cosAcosB-sinAsinB)
x+y=4cos(t+π/6)+2sint=4(cost*cosπ/6-sint*sinπ/6)+2sint
recall that cosπ//6=√3/2, and sinπ/6=1/2:
4(cost*cosπ/6-sint*sinπ/6)+2sint=4[(√3/2)cost-(1/2)sint]+2sint
simplify:2√3cost-2sint+2sint=2√3cost
