Answer:
A. 3rd equation
B. 1st equation
C. 4th equation
D. 2nd equation
The final value within the square root can't be negative or else the solution is imaginary, and you also cannot divide by a value of zero.
Answer:
A
Step-by-step explanation:
Given
= 8 + 4A
Multiply through by 3 to clear the fraction
2A = 24 + 12A ( subtract 12A from both sides )
- 10A = 24 ( divide both sides by - 10 )
A = - 2.4 → A
Well subtract 8 from 1000 and then do that five times. so 992,984,976,968, and 960<span />
Answer:it will take 5 years
Step-by-step explanation:
Initial amount deposited into the account is $500 This means that the principal is
P = 500
It was compounded quarterly. This means that it was compounded 4 times in a year. So
n = 1
The rate at which the principal was compounded is 5.6%. So
r = 5.6/100 = 0.056
The formula for compound interest is
A = P(1+r/n)^nt
A = total amount in the account at the end of t years. A is already given as $750
Therefore,
750 = 500 (1+0.056/4)^4×t
750 = 500 (1+0.014)^4t
750 = 500 (1.014)^4t
(1.014)^4t = 750/500 = 1.5
Take root 1/4 of both sides
(1.014)^4t ×1/4 = 1.5^1/4
(1.014)^t = 1.107
t = 5 years
Answer is a :
100 + 300% of 100 = 400
but the markup is more than 300%
ans : a)
