You need to estimate the square root of 200 ft². Rewrite 200 as 2 x 100, then square root of (2*100) is:

10*sqrt(2). The sqrt(2) = 1.414, so the length of each side of the square will be 10*1.414 = 14.14 ft or about 14 ft.

Answer:

The value of k is 1.

Step-by-step explanation:

x – 1 is a factor of f(x)

This means that:

x - 1 = 0

x = 1

That means that when $x = 1, y = 0$ . We use this to find the value of k.

f(x) = 3x^3 - 4x + k

$3*1^3 - 4(1) + k = 0$

$3 - 4 + k = 0$

$k = 1$

The value of k is 1.
