Answer:
8.89 feet
Step-by-step explanation:
The square of the side length is 79 ft², so the side length is the square root of that:
√(79 ft²) ≈ 8.88819 ft ≈ 8.89 ft
Get into ax²+bx+c=0 form
subsitute u=x⁴
x⁸-3x⁴+2=0
(x⁴)²-3(x⁴)+2=0
u²-3u+2=0
factor
(u-2)(u-1)=0
set to zero
u-2=0
u=2
u-1=0
u=1
wait, u=x⁴
2=x⁴
![\sqrt[4]{2}=x](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B2%7D%3Dx)
1=x⁴
+/-1=x
the subsitution is u=x⁴
and the possible values for x are -1,
![\sqrt[4]{2}=x](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B2%7D%3Dx)
, and 1
Answer: E. Convenience
Step-by-step explanation:
- A convenience sampling is a method of sampling whose structure is based on accessibility to the researcher .
Given : An internet site asks its members to call in their opinion regarding their web searching habits.
Here the internet site is working according to its accessibility .
Hence, this is a type of convenience sampling .
[ (12 - n)/7 ] = -1
12- n = -7
-n = -19
n = 19
