If A=[1 0 -1 7] find K such that A^2-8A-ki-KI=0

K = -7

Step-by-step explanation:

If A=[1 0 -1 7] find K such that A^2-8A-ki-KI=0

Given the 2×2 matrices

A =

We are to find K if  =0

A² =  

A² =

8A = 8

8A =

Since

Substitute the resulting matrices into the expression above:

A^2-8A-KI =   - - =

From the expression, we have the equations;

1 - 8 - k = 0

-7 - k = 0

-7 = k

k = -7

Hence the value of K is -7

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
