Determine the range
To do this, we simply substitute the values of n in the given expression
So, we have:
Hence, the range is:
Answer:
x= 60 y=50
Step-by-step explanation:
First to find x, all the degrees in a triangle add up to 180 degrees. So 50+70+x=180 which is also 120+x=180 which means x=60. Y is the exterior angle of x and a missing angle. Let's substitute the missing angle with the variable z. 60+50+z=180 which is 110+z=180 which means z is 70. So 180-x+z=y. 180-60+70=y which means y is equal to 50. Hope this helps!
Recall that the characteristic polynomial of a 2x2 matrix
is
but
and
, so the characteristic polynomial for
is
We're given that the trace is 15 and determinant is 50, so the characteristic polynomial for the matrix in question is
and the eigenvalues are those
for which the characteristic polynomial evaluates to 0.
How did you get 12? It should be 11 because 9+2=11.
