Answer:
Step-by-step explanation:
Given that:
The investment amount in account = $ 320
The rate of interest is = 8.1% compounded quarterly
Compunded quarterly means 8.1% / 4 = 0.02025
The time period = t years
The objective is to write a function showing the value of the account after t years.
From compound interest , compounded monthly.
Thus; the function after t years
The percentage of growth per year is :
= (1 + 0.02025)^4 - 1
= 1.083493758 - 1
= 0.083493758
= 8.4 % (APY) yearly
Answer:
A number line with an open circle on -6, shading to the left, and a closed circle on 5, shading to the right
Step-by-step explanation:
we have
----> inequality A
or
----> inequality B
<em>Solve inequality A</em>
The solution of inequality A is the interval ----> (-∞, -6)
<em>Solve inequality B</em>
The solution of inequality B is the interval ----> [5,∞)
The solution of the compound inequality is
(-∞, -6) ∪ [5,∞)
The solution is
A number line with an open circle on -6, shading to the left, and a closed circle on 5, shading to the right
Answer:
-1 3/5
Step-by-step explanation:
-4/5 - 4/5= -8/5
-8/5= -1 3/5
you can figure it out by using Google btw
Simplify the expression
-10
Hope this helps! :)
Using continuous compounding, it is found that the value of r is of r = 7.7%.
<h3>What is continuous compounding?</h3>
The amount of money after t years in continuous compounding is:
In which:
- P(0) is the initial amount.
- r is the exponential growth rate.
The doubling time of 9 years means that P(9) = 2P(0), which is used to find r, hence:
r = 0.077.
r = 7.7%.
