N^4 - 1 = (n^2 - 1)(n^2 + 1)
= (n + 1)(n - 1)(n^2 + 1)
Answer:
x=4
Step-by-step explanation:
In triangle MLK
- it is a equilateral triangle
- Hence
- ML=LK=MK=5
Now come to triangle MKJ
- It is a isosceles triangle
- Hence
- MJ=Mk
MK=5
Hence




Answer:
cos 52 = 11/alpha ---> alpha = 11/cos52 = 17.9
Answer:
1. The minus before the |x| reflects the function in the x-axis. So it will still be V-shaped but instead but refected in the x-axis.
2. The +4 moves the function vertically 4 units upwards.
Step-by-step explanation:
We are given the function f(x) = - |x| +4. We know that the function f(x) = |x| only has positive values, so when x>0 the function is a straight line as in the function f(x) = x. When x<0 the function is also positive, as in the function f(x) = -x. So the graph is V-shaped with the vertex at the origin.
The f(x) = - |x| +4 has two important caracteristics:
1. The minus before the |x| reflects the function in the x-axis. So it will still be V-shaped but instead but refected in the x-axis.
2. The +4 moves the function vertically 4 units upwards.
So the graph of f(x) = - |x| +4 will be V-shaped, reflected in the x-axis and moved 4 units upwards.

Answer:
x=0
The line of symmetry here is the same as the y-axis. Along the y-axis, x=0.
