Answer:
At the end of 3 years, we could save upto $ 2975.4 with an interest rate of 3.3 %
Step-by-step explanation:
If we are putting $ 2700 into our IRA ( individual Retirement Account) for 3 years and we are earning 3.3% profit every year, we need to find the total amount saved at the end of 3 years.
Since the interest is calculated for more than 1 year, this is an example of compound interest.
The formula used is:
where FV = future value
P= Principal amount of money deposited
r= annual interest rate ( in decimal form)
n= number of times interest rate is compounded (yearly)
t= time period
So for our given guestion:
P= $2,700
r = 3.3 % = 0.033
n= 1
t= 3
putting our values in the formula
So, at the end of 3 years, we could save upto $ 2975.4 with an interest rate of 3.3 %
Answer:
d.
Step-by-step explanation:
We have been given that Cheng measures each edge of each base to be 2 feet. The height of the whole sculpture is 6 feet.
First of all, we will find height of each pyramid by dividing height of whole sculpture by 4 as:
We know that volume of a pyramid is equal to 1/3 of base area times height that is , where b represents area of base.
Since volume of one pyramid is equal to 2 cubic feet, so volume of 4 pyramids will be 4 times 2 cubic feet that is 8 cubic feet.
Therefore, Cheng must purchase 8 cubic feet of material.
Answer:a rectangular array of quantities or expressions in rows and columns that is treated as a single entity and manipulated according to particular rules.
Step-by-step explanation:For example, the matrix A above is a 3 × 2 matrix. Matrices with a single row are called row vectors, and those with a single column are called column vectors. A matrix with the same number of rows and columns is called a square matrix.
