Answer:
(-3,5) lies in Quadrant 2
the solution is b
Answer:
8 years.
Step-by-step explanation:
The simple interest formula is principal × rate (as a decimal) × time = interest. In this question, you want to find the time.
First, plug in your numbers. 350 × .055 × t = 154. Then, to find t, divide to get t one side.
t = 154 / 350 × .055
Then solve.
350 × .055 is 19.25. 154 / 19.25 is 8.
So, your answer is 8 years.
154/350*.055 = t

N = 1 * 1 * 9 * 10 * 10 * 10 * 10 * 10 * 10 = 9,000,000</span>
2040 = n/2(20+(n-1)4)
4080 = n(20+4n-4)
4080= 20n +4n^2 -4n
1020 = 4n + n^2
n^2 +4n -1020 =0
use common formula (can't write out so just look at answers. sorry)
which gives answers of n=-34 and n=30. since n can only be positive, n=30 so there are 30 rows. I liked that challenge
