Answer:

$133507.33

Step-by-step explanation:

x = number of 6 month periods

y = total money in account

After 10 years:

$y = 300x(1.09)^x$

$y = 300(20)(1.09)^2^0$

$y = 6000(5.60441077)$

$y = 33626.46$

After 18 years:

$y = 33626.46(1.09)^x$

$y = 33626.46(1.09)^1^6$

$y = 33626.46(3.97030588)$

$y = 133507.33$

What are all the real zeros

xeze [42]

For this case we have a function of the form $y = f (x)$ , where $f (x) = (x-12) ^ 3-10$

To find the real zeros we must equal zero and clear the variable "x".

$(x-12) ^ 3-10 = 0$

We add 10 to both sides of the equation

$(x-12) ^ 3-10 + 10 = 10\\(x-12) ^ 3 = 10$

We apply cube root to both sides of the equation:

$\sqrt[3]{(x-12)^3} = \sqrt[3] {10}\\x-12 = \sqrt[3] {10}$

We add 12 to both sides of the equation:

$x-12 + 12 = \sqrt[3] {10} +12\\x = \sqrt[3] {10} +12$

slavikrds [6]

Answer:

293.04 miles

Step-by-step explanation:

249.48 miles / 12.6 gallons is a proportion that is given to be true so we look to find an equivalent fraction that has 14.8 gallons in it and that respects this proportion.
