If a quadratic equation has an imaginary root -4i, then its conjugate i. E. 4i will be the other root of the equation. Step-by-step explanation: a. The only imaginary root of a quadratic equation is -4i, this is not possible. Because, if a quadratic equation has an imaginary root -4i, then it's conjugate i. E. 4i will be the other root of the equation. b. So, the two roots of a quadratic equation are imaginary and they are 4i and -4i. Therefore, the equation will be (x - 4i)(x + 4i) = 0 ⇒ ⇒ ⇒ (Answer)

In a heat transfer course, we can derive the equation for the temperature distribution in a flat rectangular plate. in this example, we will look at a plate at steadystate with three sides being held at t1, and one side held at t2. the temperature for any location on the plate, t(x,y), can be calculated by where create a function (prob3_5) that will take inputs of vectors x and y in feet, scalar n, scalars l and w in feet and scalars t1 and t2 in degrees fahrenheit. it will output a matrix t which is the temperature of each x and y locations. t will have the number of columns equal to the number of elements in x and rows equal to the number of elements in y. though this can be done without loops (perhaps more efficiently), your program must use a nested loop.
