Answer:
9.2
Step-by-step explanation:
6i + 4j written in component form is < 6, 4 >.
If we factor a 2 out of each component we get this,
2 < 3, 2 >
This now represents a scalar times the vector < 3, 2 >.
Let's just give it a different scalar value to find a vector in the same direction.
1 < 3, 2 > = 3i + 2j
3 < 3, 2 > = 9i + 6j
4 < 3, 2 > = 12i + 8j
So there are some other vectors going in the same direction as 6i + 4j but with different magnitudes. We can see that 3i + 2j is one of our options, ya?
Answer:
r = 3/5
Step-by-step explanation:
S_∞ = a/(1 – r)
A geometric series has first term 2 and sum to infinity 5.
1)Find the common ratio.
= S_∞ = a/(1 – r)
5 = 2/1 - r
Cross Multiply
5(1 - r) = 2
5 - 5r = 2
5 - 2 = 5r
r = 5 - 2/5
r = 3/5
2)Find the sum of the first 10 terms of the series.
The sum of the first 10 terms =
S
