The answer is e none of the above
Answer:
7.405882353 years
Step-by-step explanation:
Simple interest is
A = P(1+rt)
Where A is the amount in the account
P is the principle invested
r is the rate and
t is the time
6593.75 = 5000( 1+ .0425*t)
Divide each side by 5000
6593.75/5000 = ( 1+ .0425*t)
1.31475 = ( 1+ .0425*t)
Subtract 1 from each side
.31475 = .0425t
Divide each side by.0425
.31475/.0425 = .0425t/.0425
7.405882353 = t

Arc length, (s)=(radius, r)(central angle, q)
s=rq
q=s/r
q=4/10
q=2/5, or 0.4 radians
Answer:
Eldest: $298500
Middle: $165250
Youngest: $149250
Explanation:
We can show the siblings like this:
e=2y (eldest)
m=16000+y (middle)
To find the value of y, or the youngest sibling, we use an equation.
2y+16000+y+y=613000
Simplify:
4y+16000=613000
Subtract 16000 on both sides:
4y=597000
Divide both sides by 4:
y=149250
The youngest received $149250.
Knowing this, we can plug in the numbers into the original formulas:
e=2(149250)=298500 ...or $298500
m=16000+149250=165250 ...or $165250
y=149250 ...or $149250
Add all those numbers up, and you reach $613000.
Given the expression (8+3i)+(-2+i)
We need to simplify it.
(8+3i)+(-2+i)
First we have to remove the parenthesis.
8+3i-2+i
As we know that multiplication of positive and negative is negative.
Now we will add or subtract like terms. Like terms means here i with i and constant term with constant term. So here we will add 3i and i. Also subtract 2 from 8.
8-2 +3i+i
6+4i
We have got the required answer.
The simplified answer is 6+4i.
