Determine n between 0 and 19 such that (2311)(3912) ≡ n mod 20.
sleet_krkn [62]

You can write 2311 and 3912 in the form 20q+r:

2311=115\cdot20+11

3912=125\cdot20+12

Then

2311\cdot3912=(115\cdot20+11)(125\cdot20+12)

2311\cdot3912=115\cdot125\cdot20^2+(11\cdot125+12\cdot115)\cdot20+11\cdot12

Taken modulo 20, the terms containing powers of 20 vanish and you're left with

2311\cdot3912\equiv11\cdot12\equiv132\pmod{20}

We further have

132=6\cdot20+12

so we end up with

2311\cdot3912\equiv12\pmod{20}

and so n=12.

###

If instead you're trying to find 2311^{3912}\pmod{20}, you can apply Euler's theorem. We can show that \mathrm{gcd}(2311,20)=1 using the Euclidean algorithm. Then since \varphi(20)=8, and 8 divides 3912, we have

2311^{3912}\equiv2311^{489\cdot8}\equiv(2311^{489})^8\equiv1\pmod{20}

To show 2311 and 20 are coprime:

2311 = 115*20 + 11

20 = 1*11 + 9

11 = 1*9 + 2

9 = 4*2 + 1   =>  gcd(2311, 20) = 1

Find BA if B(-3,-1) and A(0,1). Round to the nearest tenth.
Dvinal [7]

Answer:

BA=\sqrt{13}

Step-by-step explanation:

We are given two point B(-3,-1) and A(0,1)

We need to find distance BA

Using distance formula of two coordinate

D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Where,

(x_1,y_1)\rightarrow (-3,-1)

(x_2,y_2)\rightarrow (0,1)

Now we substitute points into formula and we get BA

BA=\sqrt{(0-(-3))^2+(1-(-1))^2}

BA=\sqrt{(0+3)^2+(1+1)^2}

BA=\sqrt{3^2+2^2}

BA=\sqrt{9+4}

BA=\sqrt{13}

Thus, Distance BA would be \sqrt{13}
