Answer:

The equation used is

(\text{Remaining side})^2=14^2-9^2  

Step-by-step explanation:

Given that the hypotenuse of a right triangle has a length of 14 units and a side that is 9 units long.

we have to find the equation which is used to find the length of the remaining side.

In right angled triangle Pythagoras theorem can be used to find the length of one side if two sides are given as

Hypotenuse^2=(one \thinspace side)^2+(other\thinspace side)^2

14^2=9^2+(\text{Remaining side})^2

(\text{Remaining side})^2=14^2-9^2

which is required equation

Using the Pythagorean therom.

9^{2} + b^{2} = 14^{2}
81 + b^{2} = 196
b^{2} = 115
b = \sqrt{115}

Hope this helps!

Prove that if a is equivalent to 5 mod (8) and b is equivalent to 3 mod (8), then 8 divides ab+1
olga nikolaevna [1]

Answer:

Explanation contains the proof.

Step-by-step explanation:

a \equiv 5 (mod 8) \text{ means there is integer } k \text{ such that } a-5=8k.

b \eqiv 3 (mod 8) \text{ means there is integer } m \text{ such that } b-3=8m.

We want to show that 8 \text{ divides } ab+1.  So we are asked to show that there exist integer n \text{ such that } 8n=ab+1 \text{ or 8n-1=ab

So what is ab?

a-5=8k \text{ gives us } a=8k+5.

b-5=8m \text{ gives us } b=8m+5.

So back to ab....

ab

=(8k+5)(8m+5)

=64km+40k+40m+25  (I use foil to get this)

Factoring out 8 gives us:

=8(8km+5k+5m)+25

Now I could have factored some 8's out of 25.  There are actually three 8's in 25 with a remainder of 1.

=8(8km+5k+5m+3)+1

We have shown that there is integer n \text{ such that } ab=8n-1.

The integer I found that is n is 8km+5k+5m+3.

Therefore 8|(ab+1).
