Answer:
-10,2
Solve by factoring set each equation equal to 0.
2x-4=0
X+10=0
Simplify
A(1)=2*5^1-1=2*5^0=2*1=2
a(4)=2*5^4-1=2*5^3=2*125=250
a(8)=2*5^8-1=2*5^7=2*78,125=156,250
C: 5x (x-4)
If you were to distribute the 5x to everything in parentheses, you would get 5x squared (5x × 5) and -20x (5x × -4)
and 
There are 6 possible outcomes when rolling a die, 1, 2, 3, 4 , 5, 6
A
numbers less than 4 are 1, 2, 3
P( number less than 4 ) =
= 
B
numbers greater than 4 are 5, 6
P( number greater than 4 ) =
= 
Answer:
Step-by-step explanation:
θ is the angle the ladder makes with the ground.
θ = arcsin(13.8/14) ≈ 80.3° > 78°
The ladder is not safe at that height and angle.
