The following represent matrices and the dimension of each is also stated below. A is a matrix of size 4X2 B is a matrix of size 3X5 C is a matrix of size 7X2 D is a matrix of size 5X4 E is a matrix of size 5X3.
Which of the following matrices products are defined?
Answer:
EB is defined
BE is defined
BD is defined
and DA is defined
Step-by-step explanation:
To know that the product of two matrices are defined, the column of the first matrix must be the same as the row of the second matrix.
For example; for EB we have 5 columns for E and 5 rows for B. After this product is done it produces a matrix with dimension 3 x 3, which means 3 by 3 (3 rows by 3 columns)
Answer: 493,700,000
Step-by-step explanation:
Solve for x.
- 10= -6+ 2x
Simplify your answer as much as possible.
x=
Answer:
-2
Step-by-step explanation:
-10 = -6 + 2x
-10+6=2x
-4÷2x
-2=x
the nearest dollar, would be in the account after 8 years?
Abigail can find out how much money she will have after 8 years continuously compounding interest by using the formula A = P*e^(rt), where A is the final amount, P is the principal ($29,000), r is the interest rate (0.021), and t is time in years (8). Once the values are inserted into the formula, it can be solved to find the total amount.
The problem that Abigail is facing can be solved using the continuous compound interest formula which is A = P*e^(rt). Here, A stands for the amount of money in the account after t years, P is the principal amount (the initial amount of money), r represents the annual interest rate (expressed as a decimal), and t is time in years. In this context:
Plug in these values into the formula:
A = 29000 * e^(0.021 * 8)
When calculated this would give the total amount to the nearest dollar.
