Answer:
Step-by-step explanation:
<u>Solution 1:</u>
Notice the coordinate of both points are equal, meaning both points are on a vertical line. The distance between two points on a vertical line is the absolute difference of their y-coordinates. The absolute difference between and is .
<u>Solution 2:</u>
The distance between two points and is:
Plugging in given values, we have:
.
We can solve this in 2 ways
Since a1 = 4
a2 = 4 * (3) = 12 i.e( a1* common ratio)
a3 = 12 * (3) = 36 i.e( a2 * common ratio)
a4 = 36 * (3) = 108 i.e( a3* common ratio)
a5 = 108 * (3) = 324 i.e(a4*common ratio)
and so on
Answer:
2,380
Step-by-step explanation:
This is a selection problem, hence it is combination. It is simply telling us in how many ways can we select a group of 13 from 17.
This is straightforward, we only need to apply the combination formulae. Hence this goes thus:
17C13 = 2,380
There are 2,380 ways to do this task
