suppose you are the financial manager of the International Emirates University IEU. And you are requested at the end of the year
Irina18 [472]
So what this is is
many words

assuming year 0 is 2017

so compound first thing till 2020, take out 30000
the remaining is copmpounded til 2022, take out 50000
remaining is compounded for 1 more year and that is equal to 80000

so from 2017 to 2020, that is 5 years
from 2020 to 2022 is 2 years
from 2022 to 2023 is 1 year


work backwards

A=P(r+1)^t
last one
A=80000
P=?
r=0.08
t=1 year

80000=P(1.08)^1
divide both sides by 1.08
I would leave in fraction
20000000/27=P

now that is the remaining after paying 50000, after 2 years of compounding

so
50000+(2000000/27)=P(1.08)^2
solve using math
about
106374=P

now reverse back

5 years
paid 30000

30000+106374=P(1.08)^5
solve using math
92813.526=P
round
$92813.53




put $92813.53 in the fund

Using the quadratic formula to solve 2x2 = 4x – 7, what are the values of x? 2 plus-or-minus StartRoot 10 EndRoot i 1 plus-or-mi
ioda

Answer:

x = 1 +/- \frac{i\sqrt{10} }{2}

Step-by-step explanation:

The equation given is:

2x^2 = 4x - 7\\\\2x^2 - 4x + 7 = 0

Using quadratic formula:

x = \frac{-b +/- \sqrt{b^2 - 4ac} }{2a}

From the question:

a = 2, b = -4, c = 7

Therefore:

x = \frac{4 +/- \sqrt{(-4)^2 - 4 * 2 * 7} }{2 * 2}\\\\x = \frac{4 +/- \sqrt{(16 - 56)} }{4}\\\\x = \frac{4 +/- \sqrt{-40} }{4}\\

=> x = 1 +/- \frac{i\sqrt{10} }{2}
