What is the value of c in the interval (5,8) guaranteed by Rolle's Theorem for the function g(x)=−7x3+91x2−280x−9? Note that g(5
jeyben [28]

Answer:

\displaystyle c = \frac{20}{3}

Step-by-step explanation:

According to Rolle's Theorem, if f(a) = f(b) in an interval [a, b], then there must exist at least one <em>c</em> within (a, b) such that f'(c) = 0.

We are given that g(5) = g(8) = -9. Then according to Rolle's Theorem, there must be a <em>c</em> in (5, 8) such that g'(c) = 0.

So, differentiate the function. We can take the derivative of both sides with respect to <em>x: </em>

<em />\displaystyle g'(x) = \frac{d}{dx}\left[ -7x^3 +91x^2 -280x - 9\right]<em />

Differentiate:

g'(x) = -21x^2+182x-280

Let g'(x) = 0:

0 = -21x^2+182x-280

Solve for <em>x</em>. First, divide everything by negative seven:

0=3x^2-26x+40

Factor:

<h3>0=(x-2)(3x-20)</h3>

Zero Product Property:

x-2=0 \text{ or } 3x-20=0

Solve for each case. Hence:

\displaystyle x=2 \text{ or } x = \frac{20}{3}

Since the first solution is not within our interval, we can ignore it.

Therefore:

\displaystyle c = \frac{20}{3}

A and B are n×n matrices. Check the true statements below: A. (detA)(detB)=detAB. B. The determinant of A is the product of the
Rudik [331]

Answer with Step-by-step explanation:

We are given that

A and B are matrix.

A.We know that for two square matrix A and B

Then, det(AB)=det(A)\cdot det(B)

Therefore, it is true.

B. det A  is  the product of diagonal entries in A.

It is not true for all matrix.It is true for upper triangular matrix.

Hence, it is false.

C.\lambda+5=0

\lambda=-5

When  is a factor of the characteristics polynomial of A then -5 is an eigenvalue of A not 5.

Hence, it is false.

D.An elementary row operation on A does not change the determinant.

It is true because when an elementary operation applied then the value of matrix A does not change.
