Since y = -4
The y intercept is (0,-4)
Let's say BB' = a
2^2 + 1^2 = a^2
4 + 1 = a^2
a^2 = 5
a = √5
So the distance of BB' is √5
It is: No, he is not correct and the correct solution is 10r +10
-2r-5a+12r+10+5a
-5a+10r+10+5a
10r+10
Answer:
20.4 years (nearest tenth)
Step-by-step explanation:
<u>Compound Interest Formula</u>
where:
- A = final amount
- P = principal amount
- r = interest rate (in decimal form)
- n = number of times interest applied per time period
- t = number of time periods elapsed
Given:
- A = $15,000
- P = $6,000
- r = 4.5% = 0.045
- n = 12 (monthly)
Substitute the given values into the formula and solve for t:
Therefore, it would take 20.4 years (nearest tenth) for the investment to reach $15,000.
