Volume of cube is side power 3
therfore cubic root volume = side length
volume = 512 --> cubic root 512 =8 cm
side length is 8 cm if it was doubled
side length= 16 cm
therefore side length after doubling =
side power 3
(16) to the power 3 = 4096 cm3
The answer is $1219
Interest = Total amount * interest rate * time (
I=prt is the formula for calculating interest)
In this case,
Total amount = $1200
Interest rate= $ 0.19
Time span for which interest rate is being calculated= 1/12
(since the rate is yearly and we are calculating interest for a month)
Interest = 1200*0.19*1/12 = 19
So the total amount owned by family at the end of one month
= original amount + interest = $1200 +
$19 = $1219
Answer:

Step-by-step explanation:

Apply exponent rule: 


Answer:
- The interval [9, 10] is 1,375% greater than the interval [5, 8].
- The interval [9, 10] is 14.75 times greater than the interval [5, 8].
Step-by-step explanation:
1. To solve this problem you must apply the following formula:

2. Let's calculate the average rate of change of each interval:
a) Interval [9,10]:

b) Interval [5,8]:

3. The difference is:

4. In percentage:

5. You have that the interval [9,10] is 14.75 times greater than the interval [5,8], as you can see below:
