(3x - 4)(2x^2 + 2x - 1) = 3x(2x^2 + 2x - 1) - 4(2x^2 + 2x - 1) = (6x^3 + 6x^2 - 3x) - (8x^2 + 8x - 4) = 6x^3 + 6x^2 - 3x - 8x^2 - 8x + 4 = 6x^3 - 2x^2 - 11x + 4
Answer:
12 feet
Step-by-step explanation:
30 divided by 5= 6
6 times 3= how far youve already swam(18 feet)
6 times 2= how far you have left(12 feet)
Hello,
if n=15: (4,1),(31,8),(244,63)
if n=7: (8,3),(127,48),(2024,765)
if n=99: (10,1),(199,20),(3970,399)
(Pell 's equation)
<span>im pretty sure it would be 1 in 3 or 1 in 4</span>
For this case, the first thing to do is to use the equation of the given line.
We have then:
f (x) = 0.76x + 42.39
We substitute the value of x = 15:
f (15) = 0.76 * (15) + 42.39
f (15) = 53.79
Then, subtracting with the original value we have:
53.79-52.04 = 1.75
Answer:
the residual for when x = 15 is:
1.75
