Answer:
y1= 0, y2= 5/3
Step-by-step explanation:
Remove the parentheses and multiply
then cancel the equal terms
collect the lie terms
move the variables to one side
divide both sides by two
split into possible cases
then solve the equation to get
y= 0 and
y= 5/3
Answer:
even i dont know can help
Answer:
12.
m∠ACB = 180° - 58° - 78° = 44°
m∠DCE = 180° - 85° - 60° = 35°
m∠BCD = 180° - 44° - 35° = 101°
13.
Base on the picture, we know that:
x° + 2x° + 3x° = 180°
6x° = 180°
x° = 180° ÷ 6 = 30°
=> m∠K = 2x° = 2 × 30° = 60°
=> m∠L = 3x° = 3 × 30° = 90°
=> m∠KML = x° = 30°
m∠LMN = 60° + 90° = 150°
Answer:
a). converges
b). diverges
c). converges
Step-by-step explanation:
{ 
} = { 
}
Using radio test,
L = 
= 
= 
= 
= |r|
Therefore, 
converges in |r| < 1
a). r = 1/5
This sequence is monotonically decreasing and bounded.
0 < < 1
Hence, { } converges.
b). r = 1
{ } = { n }
This sequence is monotonically increasing sequence which is not bounded.
Hence, { } diverges.
c). r = 1/6
This sequence is monotonically decreasing and bounded.
0 < < 1
Hence, { } converges.
For |r| < 1, the converges.
