1, 3, 9, 27, ...
1 answer:
Answer:
the answer is 59048
Step-by-step explanation:
as the common ratio is multiplying by 3 and the first term is 1 so from the rule (Tn=ar(power n-1 ) )
so the 11th term is 1*3(power 11-1 ) equal 3 power 10 equal 59048

AB² = AC²+BC²
AB² = 9²+12²
AB²= 225
AB= 15
SinA = 12/15
A = Sin-¹(0.8)
M`A = 53°
M`B = 90- A = 90-53= 37°
7x-y=9
3x-y=5 (multiply by -1 both sides of the equation)
7x-y=9
-3x+y=-5 (now add both equations)
7x-3x-y+y=4
4x=4 (divide by 4 both sides of the equation)
x=1
y=3x-5=3×1-5=-2
y= -2
answer: x=1, y=-2
