Answer:

1/625, or 0.0016 is the answer.

Answer:

when two lines are parallel the two slopes are equal (m1 =m2)

when two lines are perpendicular the product of the slopes is equal to -1( m1m2= -1)

m1 =1st slope

m2= 2nd slope

using the formula y= mx +c

m1= -8/9

m2= 9/8

since m1 is not equal to m2 and -8/9 × 9/8 = -1

It is perpendicular

Step-by-step explanation:

ST

3*-2 + 4*-4 = -22                3*0 + 4*5 = 20

-1*-2 + -2*-4 = 10                -1*0 + -2*5 = -10

try TS by yourself

the product of two given matrices is [tex]ST=\left[\begin{array}{cc}-22&20\\10&-10\end{array}\right][/tex] and [tex]TS=\left[\begin{array}{cc}-6&-8\\-17&-26\end{array}\right][/tex].

Given that,

[tex]S=\left[\begin{array}{cc}3&4\\-1&-2\end{array}\right][/tex] and [tex]T=\left[\begin{array}{cc}-2&0\\-4&5\end{array}\right][/tex]

The product of two matrices A and B is defined if the number of columns of A is equal to the number of rows of B. If both A and B are square matrices of the same order, then both AB and BA are defined. If AB and BA are both defined, it is not necessary that AB = BA.

Now, [tex]ST=\left[\begin{array}{cc}3&4\\-1&-2\end{array}\right] \times \left[\begin{array}{cc}-2&0\\-4&5\end{array}\right][/tex]

[tex]ST=\left[\begin{array}{cc}(-6-16)&(0+20)\\(2+8)&(0-10)\end{array}\right][/tex]

[tex]ST=\left[\begin{array}{cc}-22&20\\10&-10\end{array}\right][/tex]

[tex]TS= \left[\begin{array}{cc}-2&0\\-4&5\end{array}\right]\times \left[\begin{array}{cc}3&4\\-1&-2\end{array}\right][/tex]

[tex]TS=\left[\begin{array}{cc}(-6-0)&(-8-0)\\(-12-5)&(-16-10)\end{array}\right][/tex]

[tex]TS=\left[\begin{array}{cc}-6&-8\\-17&-26\end{array}\right][/tex]

Therefore, the product of two given matrices is [tex]ST=\left[\begin{array}{cc}-22&20\\10&-10\end{array}\right][/tex] and [tex]TS=\left[\begin{array}{cc}-6&-8\\-17&-26\end{array}\right][/tex].

[tex]6^{9}[/tex]

Step-by-step explanation:

When multiplying exponents with the same base, add the exponents:

[tex]\frac{6^{10-4} }{6^{-5+2} }[/tex] = [tex]\frac{6^{6} }{6^{-3} }[/tex]

Then use the negative exponent rule

[tex]\frac{6^{6} }{6^{-3} }[/tex] = [tex]6^{6+3}[/tex] = [tex]6^{9}[/tex]

The graphical device that divides data according to the percentage they represent is a pie-chart.

Frequency distribution, relative frequency distribution, or percent frequency distribution all are statistical measures that want to establish the part of the distribution corresponding to each measure, that is, percentages, thus they are represented by pie-charts.

An example, suppose that among 50 people sampled, 20 prefer the NBA and 30 the NFL.
