Answer:
4%
Step-by-step explanation:
The amount of simple interest is given by ...
I = Prt . . . . . amount P invested at annual rate r for t years
This can be solved for r:
r = I/(Pt)
Using the given values, we find the rate to be ...
r = 16/(200·2) = 16/400 = 4/100 = 4%
The annual interest rate is 4%.
<u>Answer:
</u>
The complete factorization of 
are 4(x-3y)(x+3y)
<u>Solution:</u>
Given Data:
Take common value in all the three term.so we take 4 as common term in the above expression
Now factorize the expression 
Find the two numbers, whose product should be 9 and sum should be -6.
-3,-3 are the numbers which satisfy the above condition.
When we add -3-3=Sum is 6
Product of -3 
-3= 9
-3 , -3 satisfies the condition.
So the expression will become as 
= 
Take the common term
x(x-3y)+3y(x-3y)
(x-3y)(x+3y)
hence the complete factorization of are 4(x-3y)(x+3y)
Answer a = 5 and b = 2.
Procedure
Initially means x = 0, then
5 = a*b^0 = a*1 = a, then a = 5
When x = 1, the height is the double of 5, i.e 10 and
10 = a.b^1 = a.b ⇒ b = 10/a = 10/5 = 2
The a = 5 and b = 2, so the equation is y =5(2)^x
This is the associative property of addition because the grouping of addends does not change the some no matter where you place the numbers in the parenthesis.
