Answer:
5√3 ft
Step-by-step explanation:
If the ladder is 10ft tall, then that represents the hypotenuse. If the foot of our ladder is 5ft away from the wall, that is a side length that we know. Using the Pythagorean Theorem, a²+b²=c², where a and b are side lengths of a right triangle, and c is the hypotenuse, we can solve for the missing side length:
a²+b²=c²
(5)²+b²=(10)²
25+b²=100
b²=75
b=√75
b=5√3
So the ladder will reach a height of 5√3 ft.
Answer:
55.56 or 55 5/9
Step-by-step explanation:
To find the time it takes to type a report, you need to divide the number of words in the report by the words the typist can type in a minute.
2500/45 = 55.56
It takes 55.56 minutes or 55 5/9 minutes to type a 2500 word report.
Answer:
= 5n - 2
Step-by-step explanation:
The terms have a common difference between consecutive terms, that is
8 - 3 = 13 - 8 = 18 - 13 = 5
This means the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference, thus
= 3 + 5(n - 1) = 3 + 5n - 5 = 5n - 2
