It will take him 30 years to earn a combined total of $100,000

Step-by-step explanation:

The earning of an employee represented by the function

f(t)=5000e^{0.1t} , where

  • f(t) is his earning in t years
  • t > 0

We need to find how many years it will take him to earn $100,000

∵ f(t)=5000e^{0.1t}

∵ The total earning = $100,000

- Substitute f(t) by 100,000

∴ 100000=5000e^{0.1t}

- Divide both sides by 5000

∴ 20=e^{0.1t}

- Insert ㏑ for both sides

∴ ㏑(20) = ㏑( e^{0.1t} )

- Remember ㏑( e^{n} ) = n

∴ ㏑(20) = 0.1 t

- Divide both sides by 0.1

∴ t = 29.957

∴ t = 30 years to the nearest year

It will take him 30 years to earn a combined total of $100,000

HEYYYY NOBODY ANSWER MY MATH QUESTION I ASK THIS MORNING THAT'S NOT FAIR!!!
Leviafan [203]

Answer:

( a+b) (a-b)

x^2 - 50

Step-by-step explanation:

The formula for difference of squares is

a^2 - b^2 = ( a+b) (a-b)

121x^2 -144 = (11x)^2 - 12^2 so this is the difference of squares

x^2 - 16y^2 = (x)^2 - (4y)^2  so this is the difference of squares

9x^2 -64 = (3x)^2-8^2  so this is the difference of squares

x^2 - 50 = (x)^2 - 2*(5)^2  this is not the difference of squares
