Answer:

Step-by-step explanation:
we know that
In a parallelogram the diagonals bisect each other
The figure XYZW is a parallelogram
so
VW=VY
VX=VZ
<em>Find the value of b</em>
VW=VY
substitute the given values

solve for b

Find the length of YW
----> by addition segment postulate

substitute the value of b

Answer:
Question D.
Pretty simple if you know what the distributive property is. In this equation, you notice 2 fractions outside the parenthesis. This means you must multiply this fraction by every number within its corresponding parenthesis. So, if you distribute the new equation would be
. After this isolate the variable y and solve. I'll leave that to you so you can get something out of it, because my entire explanation would be useless if you just looked at the answer and left, not knowing how to do it in the future. :)
Answer:
The APY of the saving account is 4.0474%
Step-by-step explanation:
We know the formula for APY which is given by

here, r= interset rate = 3.9742% = 0.039742
n = compounding cycles = 12
On plugging these values in the above formula, we get

On simplifying this we get
APY =0.04047395=4.0474%
