Here's one way to construct the second triangle. See the attached image.
Difference is subtraction.
"The subtraction of 4 times a number (4x) and nine"
This means you subtract 4x by 9
4x - 9
Answer:
Hello,
Step-by-step explanation:
We are going to use the pythagorean's theorem
distance (building ,ladder)=1+8=9 (ft)
level of the window = 11ft
length of the ladder:
Answer:
Right 18 down 12
Step-by-step explanation:
Using a geometric series, it is found that he swims 1897 yards in the first week.
In a geometric series, the quotient between consecutive terms is always the same, and it is called common ratio q.
The general equation of a geometric series is given by:
In which is the first term.
The sum of the first n terms is given by:
In this problem:
- 200 yards on the first day, thus .
- Each day, the distance increases by 10%, since 100% + 10% = 110% = 1.1, .
- First week is first 7 days, thus
Then:
He swims 1897 yards in the first week.
