Suppose that a 4 × 4 matrix A has eigenvalues λ1 = 1, λ2 = − 3, λ3 = 5, and λ4 = − 5. Use the following method to find det (A). If
p(λ) = det (λI − A) = λn + c1λn − 1 + ⋯ + cn

So, on setting λ = 0, we obtain that

det (− A) = cn or det (A) = (− 1)ncn

det (A) = ?

$20.01

step-by-step explanation:

the sale price is (1.00 - 0.77)($87), or 0.23($87), or $20.01.

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

70

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
