Verdich [7]

Answer:

Step-by-step explanation:

$\frac{2}{3}$ (18 - 9)

= $\frac{2}{3}$ × 9 ( cancel 3 and 9 by 3 )

What is the equation of the line that passes through the point (-9. 6) and is

hram777 [196]

Answer:

The perpendicular equation is y = -3x -21

Step-by-step explanation:

Perpendicular lines have the exact opposite slope as the other equation and they never have the same y-intercept.

To find the perpendicular slope just look at the slope in the original equation and get the exact opposite.

First let's simplify the equation.

-5 + x = 3y (divide by 3 on both sides to get y by itself)

-5/3 + 1/3x = y or y = 1/3x + 5/3

The exact opposite of this slope would be -3.

Now plug in the point you were given so that we can find the y-intercept.

6 = -3(-9) + b (b = y-intercept)

6 = 27 + b (subtract 27 on both sides)

-21 = b

So the perpendicular equation looks like this.

y = -3x -21

The variable r is directly proportional to the square of t, and r = 144 when t = 72.

Paul [167]

Answer:

k=0.023

Step-by-step explanation:

$r \alpha {t }^{2} \\ r = k {t}^{2} \\ 144 = k \times {72 }^{2} \\ k = \frac{144}{ {72 }^{2} } \\ k = 0.023 \\ the \: eqn \: is \: therefore \\ r = 0.023 \times {t}^{2}$

Construct a specific 2x2 matrix a with no zero entries at all such that aat = i

trasher [3.6K]

A 2 x 2 matrix has 2 rows and 2 columns

A specific 2 x 2 matrix a with no zero entries at all is $\left[\begin{array}{cc}1&-2\\-3&6&\end{array}\right]$

<h3>How to construct the matrix?</h3>

From the question, we understand that the matrix is a 2 x 2 matrix.

A 2 x 2 matrix is represented as:

$\left[\begin{array}{cc}a&b\\c&d&\end{array}\right]$

Also from the question we understand that the elements of the matrix are non-zero.

This means that:

$a \ne 0\ , b \ne 0, \ c \ne 0, \ d \ne 0$

An example of such matrix is:

$\left[\begin{array}{cc}1&-2\\-3&6&\end{array}\right]$

Note that there are several matrices that fit the given construction requirement
