Answer:

Step-by-step explanation:
We are to factorize the expression
completely. To do this, we will apply the expression below;
The expression can be rewritten as 
To factorize the expression, we need to first factorize
first

The we will make
the subject of the formula as shown;




This last result gives the expansion of the expression
The answer is 20 questions.
Answer:
4) Increase from 0 to 1
Step-by-step explanation:
We have to analyze the value of cos(Ф) from -π/2 to 0. This can be done if we simplify evaluate the value of cos(Ф) at these two extreme.

This shows that value of cos(Ф) is 0 at -π/2 or -90 degrees and increased to 0 at 0 degrees.
This answer can be validated if you visualize the graph of cos function. Cos function has a peak at 0 degrees, i.e. a value equal to 1. On right and left side of 0 degrees, the curve starts falling down and eventually touches the horizontal axis at 90 degrees and -90 degrees. This is shown in the graph attached below:
The reciprocal of 3 is 1/3.
Find the common ratio r for the geometric sequence, and use r to find the next 3 terms n 1, 2, 3, 4, 5, 6, 7 f(n) 1,4,16,64
mote1985 [20]
Divide the given terms:
4/1 = 4
16/4 = 4
64/16 = 4
R = 4
The next term is the previous term multiplied by 4.
64 x 4 = 256
256 x 4 = 1024
1024 x 4 = 4096
The next three terms are: 256, 1024, 4096
