Answer:

\frac{x}{x(x - 6)}\\\\\frac{1}{x-6}

6 is excluded

Step-by-step explanation:

The expression \frac{x}{x^2 - 6x} can be simplified by factoring the denominator and dividing out the x term.

x² - 6x = x(x-6)

It simplifies the expression by:

\frac{x}{x(x - 6)}\\\\\frac{1}{x-6}

The excluded value is any value which makes the denominator 0.

x - 6 = 0

x = 6

6 is excluded.

Find the coordinates of P so that P partitions the segment AB in the ratio 6:2 if A(−4,12) and B(9,−4).
Jobisdone [24]

<u>ANSWER</u>

B. (5.75, 0)

<u>EXPLANATION</u>

If the point P(x,y) partitioned

A(x_1,y_1)

and

B(x_2,y_2)

in the ratio m:n, then

x =  \frac{mx_2+nx_1}{m + n}

y=\frac{my_2+ny_1}{m + n}

If the coordinates are A(−4,12) and B(9,−4), then:

x =  \frac{6 \times 9+2 \times  - 4}{6 + 2}

x =  \frac{54 - 8}{8}

x =  \frac{46}{8}

x = 5.75

y=  \frac{6 \times  - 4+2 \times  12}{6 + 2}

y =  \frac{24 - 24}{8}

y =  \frac{0}{24}  = 0

The correct choice is

B. (5.75, 0)

In ΔXYZ, x = 27 cm, y = 79 cm and ∠Z=142°. Find the length of z, to the nearest centimeter.
Annette [7]

The value of side z will be equal to 99.32 cm.

<h3>What is trigonometry?</h3>

The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle are termed trigonometry.

Given that:-

In ΔXYZ, x = 27 cm, y = 79 cm and ∠Z=142°

So by applying the formula given below:-

z²   =   x²  +  y²  -  2xyCos(142)

z²   =   79²  +   27²   -  2 ( 79 x 27  x  Cos142  )

z    =    99.32  cm

Hence the value of side z will be equal to 99.32 cm.
