A:PN
C is diameter
MN =2*PN
the first x < 3 so x could be from - 1 till 3 in this graph
the other x > - 7 so x could be from from - 7 till - 3 in this graph
Answer:
The answer to this question can be defined as follows:
Step-by-step explanation:
The given equation is:

put,


hence y_k=k^2 is its solution.
Now,

the symbol form is:


The general solution is:

The complete solution is:

The answer is option b: 
After solve the complete solution is:

Answer:
1
Step-by-step explanation:
a+1=1
a=1-1
a=0
b^a which means:
b^0
whenever power is 0 answer is always one
so value of b^a is 1

Step-by-step explanation:
In this exercise we only need to recall the formula for C(n,k):

where the symbol
is the factorial and means
.
By convention 0!=1. The most important property of the factorial is
, for example 3!=1*2*3=6.
(a) The explanations to the solutions is just the calculations.
.
(b) The explanations to the solutions is just the calculations.
For all the calculations just recall that 4! =24 and 5!=120.
