Use determinants to find out if the matrix is invertible.

wariber [46]

Answer:

The matrix is not invertible.

Step-by-step explanation:

We are given the following matrix in the question:

$A =\left[\begin{array}{ccc}-5&0&1\\-1&3&2\\0&10&6\end{array}\right]$

Condition for invertible matrix:

A matrix is invertible if and only if the the determinant is non-zero.

We can find the determinant of the matrix as:

$|A| = -5[(3)(6)-(2)(10)]-0[(-1)(6)-(2)(0)] + 1[(-1)(10)-(3)(0)]\\|A| = -5(18-20)+(-10)\\|A| = 10-10\\|A| = 0$

Since the determinant of the given matrix is zero, the given matrix is not invertible.

Is it right

Rasek [7]

F(t) = t2 + 4t − 14

y + 14 + 4 = ( t2 + 4t +4)

y + 18 = ( t + 2)^2

so the vertex of the parabola is ( -2 , -18)

the axis of symmetry is y = -18

A track runner is eager to see if practicing helps her improve. She has plotted data on her weekly 100-meter dash times (s) as w

insens350 [35]

Answer:

$\displaystyle s = -\frac{1}{5}h + 20$

Step-by-step explanation:

Time is the dependent variable, so you set your function equal to s. Then, the correlation of the graph has a $\displaystyle -\frac{1}{5}$ rate of change [slope] from the y-intercept of $\displaystyle [0, 20],$ so we choose this answer choice.

I am joyous to assist you anytime.
