Answer:
26*26*25 = 16,900
Step-by-step explanation:
First, we focus on the first initial, we have 26 letters that could fit in (the whole alphabet).
In the last initial we <em>can't</em> have the same we have in the first one, so we have 25 letters (the whole alphabet minus the letter that we already choose in the first initial
).
We have <em>no restrictions</em> for the middle one, so again we have 26 letters that could fit in.
So, we have 26*26*25 combinations (we multiply them because they happen all at the same time)
There is no need to use factorials, but we can use them if you want to.
Let's notice that 26! = 26*25*24*23*22*...
In our calculation, we only need the two first factors, so we can divide by 24! =24*23*22*21*...
Therefore,
26*26*25 = 26 * 26! /24!
Answer:
The required polynomial is f(x)=
Step-by-step explanation:
Given that polynomial is passing through points (-1,-1) (0,7) ( 1,9) and (2,17)
Let, The required polynomial be f(x)=
For point (-1,-1)
f(x)=
f(-1)=
(-1)a+b-c+d=(-1) Equation 1
For point (0,7)
f(x)=
f(0)=
d=7 Equation 2
For point ( 1,9)
f(x)=
f(1)=
a+b+c+d=9 Equation 3
For point (2,17)
f(x)=
f(2)=
8a+4b+2c+d=17 Equation 4
Replacing value of d of equation 2 in equation 1,3,4
For equation 1:
(-1)a+b-c+d=(-1)
(-1)a+b-c=(-8)
For equation 3:
a+b+c+d=9
a+b+c=2
For equation 4:
8a+4b+2c+d=17
8a+4b+2c=10
Now,
On adding equation 1 and 3
For equation 1: (-1)a+b-c=(-8)
For equation 3: a+b+c=2
((-1)a+b-c)+(a+b+c)=(-8)+2
2b=(-6)
b=(-3)
Replacing value of b in equation 1 and 4:
For equation 1: (-1)a+b-c=(-8)
(-1)a+(-3)-c=(-8)
(-1)a-c=(-5) Equation 4
For equation 4: 8a+4b+2c=10
8a+4b+2c=10
8a+4(-3)+2c=10
8a+2c=22 Equation 5
For value of a and c:
Equation 4 can be write as
(-1)a-c=(-5)
a+c=5
a=5-c
Replacing value of a in equation 5
8a+2c=22
8(5-c)+2c=22
40-8c+2c=22
-6c=-18
c=3
So,
a=5-c=5-3=2
a=2
Thus,
The value of
a=2, b=(-3), c=3 and d=7
The required polynomial is
f(x)=
f(x)=
Answer:
I think it is 1
Step-by-step explanation:
10% of 500 is 50
then you multipy by 50 which is 1
I hope this helps;)
