Answer to Problem 24E
Explanation of Solution
Given information:
The given matrix is:
Calculation:
The given matrix:
To find the inverse matrix, the identity matrix and perform row operations trying to make the identity matrix to the left.
So, the given matrix with identity matrix:
Make zero in column one except the entry at row one, column
Make zeroes in column two except the entry at row
Add row
Multiply row
Make zeros in column
Add row
Subtract row
Divide row
Add row
Therefore, the solution is

- How would i solve this. More info is that b =1 but it might be better to solve this before making the substitutionarrow_forwardLet m(t) be a continuous function with a domain of all real numbers. The table below shows some of the values of m(t) . Assume the characteristics of this function are represented in the table. t -3 -2 8 11 12 m(t) -7 6 3 -9 0 (a) The point (-3, -7) is on the graph of m(t). Find the corresponding point on the graph of the transformation y = -m(t) + 17. (b) The point (8, 3) is on the graph of m(t). Find the corresponding point on the graph of the transformation y = -m (−t) . 24 (c) Find f(12), if we know that f(t) = |m (t − 1)| f(12) =arrow_forwardSuppose the number of people who register to attend the Tucson Festival of Books can be modeled by P(t) = k(1.1), where t is the number of days since the registration window opened. Assume k is a positive constant. Which of the following represents how long it will take in days for the number of people who register to double? t = In(1.1) In(2) In(2) t = In(1.1) In(1.1) t = t = t = In(2) - In(k) In(2) In(k) + In(1.1) In(2) - In(k) In(1.1)arrow_forward
