Answer:
a(n) = (3/5)a(n-1), where a(1) = 10 and n is 2 or greater.
Step-by-step explanation:
determine the common factor...The first term (10) by 3/5 results in the given second term (6); the third term is 3/5 of the second term (6), resulting in 18/5 (equivalent to 36/10 or 3.6/1, or just 3.6. Resulting in a(n) = (3/5)a(n-1).
the third term is 3.6, which, if mult. by (3/5), produces 2.16, as expected.
Thus, the recursive formula for this geometric sequence is a(n) = (3/5)a(n-1).
This is good only for a(1) = 10 and n = 2, 3, ....

The intersection of two coplanar, non-parallel lines is a point
Answer:
Step-by-step explanation:
The distance formula is d=![\sqrt{(x2-x1)^{2} +[tex]\sqrt{(0-0)^{2} + (12-3)^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%28x2-x1%29%5E%7B2%7D%20%2B%5Btex%5D%5Csqrt%7B%280-0%29%5E%7B2%7D%20%2B%20%2812-3%29%5E%7B2%7D%7D)
= 9
So in this case, the depth is measured from the bottom up
0 is the bottom of the sea
a submarine can't go above the water
so
0≤d≤depth of ocean
