Answer:
An=10^n + 1 is the expression for the nth term.
Next three terms:
100001
1000001
10000001
Step-by-step explanation:
The number ot 0's imcrease between the two 1's starting at no zeros, 1 zero, two zeros, and so on...
So the next terms are 100001, 1000001, 10000001 and that's without finding the formula.
Now let's find the formula:
A1=11=10+1
A2=101=100+1
A3=1001=1000+1
Notice we have increasing powers of 10 and then just adding 1.
A1=10^1 +1
A2=10^2 +1
A3=10^3 +1
....
An=10^n +1
The height on the wall a 15-foot ladder will reach if it is placed 3. 5 feet from the base of a wall is 14.6 feet.
Using Pythagoras theorem,
c² = a² + b²
where
c = hypotenuse
a and b are the other two legs
The ladder length represent the hypotenuse sides
The distance of the ladder to the base of the wall is one of the leg.
The height on the wall the 15 ft ladder reach is the other leg
Therefore,
a² = 15² - 3.5²
a² = 225 - 12.25
a = √212.75
a = 14.5859521458
a ≈ 14.6 feet
