Answer:

11

Step-by-step explanation:

n(A) means the number of elements in set A

Element 1=-10

Element 2=-9

Element 3=-8

Follow the pattern

Element 4=-7

Element 5=-6

Element 6=-5

Element 7=-4

Element 8=-3

Element 9=-2

Element 10=-1

Element 11=0

There are 11 elements in set A.

Also this has the same number of elements as {0,1,2,...,8,9,10} which has (10+1) elements.

You make an initial investment of $500. Fill in the table below to show how much money you would have after 3 years if your acco
Aleksandr [31]
After three years, your investment would be $575. The formula is A=P(1+(r/n)^(n*t) where A is the final amount, P is the initial balance, r is the interest rate, n is the amount of time the interest is compounded in a year, and t is the amount of time that has passed.
P=500
r= 5% is which converted into a decimal by dividing 5 by 100 which is then 0.05
n= 1 since it is compounded annually
t= 3
Hope this helped.

On a particular road map 1/2 inch represents 18 miles about how many miles apart are 2 towns that are 21/2 inches apart on this
andrew-mc [135]
So if 1/2 = 18 miles, we want to first find how many sets of 1/2 are in 21/2. We can just do this by dividing.

(21/2) / (1/2) = 21

So we know that there are 21 sets of 1/2 in 21/2, and since 1/2 and 18 are equal, we can say we know there are 21 sets of 18.

We can multiply to find this.

21 * 18 = 378

So two towns are 378 miles apart.
