Answer:

x=1±i√5

Step-by-step explanation:

the quadratic equation is in the form :

y=ax²+bx+c

y= 2x²-4x+12

x=(-b±√b²-4ac)/2a

x=-(-4)±√-4²-4(2)(12)/2a

x=4±√16-96/4

x=4±√-80/4

since the number under the square root then √-80=4i√5 ( assuming possitive numbers)

x=(4±4i√5)/4

x=4(1±i√5)/4

x=1±i√5

If your starting salary were $50,000 and you received a 4% increase at the end of every year for 15 years, what would be the tot
ycow [4]

<u>Answer-</u>

<em>The total amount you would have earned over the first 16 years is </em><em>$90047.20</em>

<u>Solution-</u>

The exponential function that would given the growth is,

P'=P(1+r)^t

Where,

P' = Future value,

P = Current value = $50000

r = rate of change = 4% = 0.04

t = time = 15 year (not 16 because the the increment occurs at year end and we want to get the value at the beginning of 16th year)

Putting the values,

P'=50000(1+0.04)^{15}

=50000(1.04)^{15}

=90047.20

Therefore, the total amount you would have earned over the first 16 years is $90047.20
