<span>Question :Why is it that any number raised to the power zero is equal to 1 and not zero ?
<span>
Answer :</span><span>When a number is raise to the power 0, we are not actually multiplying the particular number by 0. For example, let us take 20. In this case we are not actually multiplying the number 2 by 0.

We define 20 = 1, so that each power of 2 is one factor of 2 larger than the last, e.g., 1,2,4,8,16,32...</span><span>This involves the rules of exponents particularly division. 

If a is a number and x and y are also numbers, then according to the rule of division for powers with the same base, 

a^x/a^y = a^(x - y).

It says the quotient of two powers with the same base is equal to the common base raise to the exponent equal to the difference between x and y. 

So, if x = y, then a^x/a^y = a^(x -y) = a^0 

But a^x is equal to a^y, since x = y; hence a^x/a^y = 1 

Therefore, by Transitive property of Equality, 

a^0 = 1 

Thus, this result says that number raised to the power zero is equal to 1.</span></span>

Answer:

f(x)=-3(x+2)^2-2

Step-by-step explanation: the the FX graph the -3 in my equation represents the decrease(for being negative) in the graph, the positive 2 represents the x axis if that number is positive the negative 3 is going to change the x axis then will end up being negative which is why the x starts off in negative 2, the last number represents the y axis if the y axis is negative 2 the y will start off at -2

1+4=5 2+5=12 3+6=21 8+11=?
ziro4ka [17]
Okay so we just need to find out the pattern...
in this case the pattern is adding..
we did 
1 + 4 = 5 
2 + 5 = 12
we figure this one out by adding 2 and 5 twice so it look like this 
2 + 5 + 5 = 12 
now moving on to our next one 
3 + 6 = 21 
so we added 3 and added 6, three times so look
3 + 6 + 6 + 6 = 21 
so now 
8 + 11 = 96 because we added 8 and added 11, eight times look..
8 + 11 + 11 + 11 + 11 + 11 + 11 + 11 + 11 = 96 
so our answer to 8 + 11 is 96!
hope this helps:)

An angle bisector of a triangle divides the opposite side of the triangle into segments 5 cm and 3 cm long. A second side of the
attashe74 [19]
There is a little-known theorem to solve this problem.

The theorem says that
In a triangle, the angle bisector cuts the opposite side into two segments in the ratio of the respective sides lengths.

See the attached triangles for cases 1 and 2.  Let x be the length of the third side.

Case 1:
Segment 5cm is adjacent to the 7.6cm side, then
x/7.6=3/5  => x=7.6*3/5=4.56 cm

Case 2:
Segment 3cm is adjacent to the 7.6 cm side, then
x/7.6=5/3 => x=7.6*5/3=12.67 cm

The theorem can be proved by considering the sine rule on the adjacent triangles ADC and BDC with the common side CD and equal angles ACD and DCB.
