1. You have the following information:
-The annual interest rate <span>is 7.2%.
- The </span><span>simple interest is calculated quarterly.
2. Then, to solve this exercise and calculate the </span><span>periodic interest rate of Marta's Account, you only have to divide the annual interest rate (7.2%) by 1/4 year. So, you have:
</span>
=(7.2%)(1/4)
=(7.2%)/4
=1.8%
<span>What is the periodic interest rate of Marta's Account?
The answer is: </span>1.8%
Answer:
<em>The correct option will be: C. 3</em>
Step-by-step explanation:
The given table is..........
-6 -3 -1 0 1 4
27 6 2 3 6 27
<u>The formula for average rate of change</u> is:
, where
is the given interval.
Here the interval is [-3, 4]. So,
and 
Now, plugging the values of
and
into the above formula, we will get........

<u>From the given table,</u> we will get
and 
So, the average rate of change will be: 
Answer:

Step-by-step explanation:
you can use hypotenuse formula
45-45-90 isosceles right triangle
so, 45= x
x² + x² = 24²
2x² = 24²
x²= 24.12
x= 
or :
you can use this rule: if you see a 45 45 90 isosceles right triagngle (you can look picture) 45=a cm and 90 = 
cm
so ;

a= 
hope this helps ^-^
