Answer:
The answer to your question is 24.7 ft
Step-by-step explanation:
Data
length of the ladder = 25 ft
distance from the ladder to the ladder = 4 ft
distance from the floor to the ladder = ?
Process
1.- Use the Pythagorean theorem to solve this problem
c² = a² + b²
- solve for b
b² = c² - a²
-Substitution
b² = (25)² - (4)²
-Simplification
b² = 625 - 16
b² = 609
-Result
b = 24.67 ft ≈ 24.7 ft
-Conclusion
The ladder is 24.7 ft from the floor.
Answer:
18 and 9
Step-by-step explanation:
The numbers are x and 1/2x.
x + 1/2x = 27
3/2x = 27
x = 18 so the numbers of 18 and 9.

Answer: a = 5n - 14
Step-by-step explanation: To write an explicit formula for an arithmetic sequence, we first need to identify the zero term of our sequence.
Since we know this is an arithmetic sequence, each time a number increases by 5 so our common difference is 5.
To find the zero term of the sequence, we will need to extend our arithmetic sequence so we will be subtracting 5 from -9 and we will get -14.
Now, we use the generic version for finding the nth term of an arithmetic sequence.
Explicit formula: a = 5n - 14
