He purchased items worth 41.23.....she was charged 50.23
50.23 - 41.23 = 9 <== she paid 9 extra dollars
The formula for exponential growth is y=a(1+r)
. Where a is the initial value when time is 0 (100 in this case). r is the growth rate, we can see that the growth is 10%. And x is how much time has passed, we want to find out how many trucks after 9 years.
So we would plug the values in to get y=100(1+.1)
. Solving this gives us 235.79, so we would round up to 236, and our answer would be 236 trucks registered in the city in year 9.
Edit: The x and the 9 are exponents, the formatting made them look a bit weird.
No, it isn't. A polygon is a closed figure with 3 or more sides.
Answer:
A) .
Step-by-step explanation:
We have been given an image of a square pyramid and we are asked to find the volume of our given pyramid.
, where,
a = Base length of square,
h = height of pyramid.
Upon substituting our given values in above formula we will get,
Therefore, the volume of our given square pyramid is 24 cubic meters and option A is the correct choice.
So for 32 it’s Pi*squared. So Pi*8^2. If ur rounding to no decimal places. Then it will be 201. So 32 is c)201
