An investment promises a return of 12% per year. Brody wants to figure out how much money he will have if he invest $1000 for 5,

jeka57 [31]

the exponential function f(x) = $1000(1.12)^x$

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) = $1000(1.12)^x$

f(5) = $1000(1.12)^5$ = 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) = $1000(1.12)^10$ = 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) = $1000(1.12)^15$ = 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

Find the smallest positive integer k such that 3240/k is a square number

sashaice [31]

Answer:

10

Step-by-step explanation:

First, factorize the number 3,240:

$3,240=2\cdot 1,620=2\cdot 2\cdot 810=2\cdot 2\cdot 2\cdot 405=2\cdot 2\cdot 2\cdot 2\cdot 5\cdot 81=2^3\cdot 5\cdot 9^2$

So,

$3,240=2^2 \cdot 2\cdot 5\cdot 9^2=18^2\cdot 10$

Now consider the fraction

$\dfrac{3,240}{k}=\dfrac{18^2\cdot 10}{k}$

If k = 10, then

$\dfrac{3,240}{k}=\dfrac{18^2\cdot 10}{10}=18^2$

is a square number.

For all k < 10, the fraction tex]\dfrac{3,240}{k}[/tex] is not a square number (this follows from factorization).

Or you can simply check the values of the fraction for all k < 10:

k = 1, $\dfrac{3,240}{1}=3,240$ is not a square number;
k = 2, $\dfrac{3,240}{2}=1,620$ is not a square number;
k = 3, $\dfrac{3,240}{3}=1,080$ is not a square number;
k = 4, $\dfrac{3,240}{4}=810$ is not a square number;
k = 5, $\dfrac{3,240}{5}=648$ is not a square number;
k = 6, $\dfrac{3,240}{6}=540$ is not a square number;
k = 7, $\dfrac{3,240}{7}$ is not a square number;
k = 8, $\dfrac{3,240}{8}=405$ is not a square number;
k = 9, $\dfrac{3,240}{9}=360$ is not a square number.
