Answer:
use a calculator
Step-by-step explanation:
the exponential function f(x) =
he invest $1000 for 5, 10, 15 years
5 years,
To find the amount of money he have , we plug in 5 for x and find out f(5)
f(x) =
f(5) =
= 1762.34
The amount of money he have after 5 years is 1762.34
10 years,
To find the amount of money he have , we plug in 10 for x and find out f(10)
f(10) =
= 3105.85
The amount of money he have after 10 years is 3105.85
15 years,
To find the amount of money he have , we plug in 15 for x and find out f(15)
f(15) =
= 5473.57
The amount of money he have after 15 years is 5473.57
f(5) = 1762.34
f(10) = 3105.85
f(15) = 5473.57
Answer:
x = 7
Step-by-step explanation:
Let
x = the unknown number
double it :
2x
add 11:
2x + 11
I get 25:
The equation is
2x + 11 = 25
2x = 25 - 12
2x = 14
Divide both sides by 2
x = 14/2
x = 7
