Answer:

Step-by-step explanation:

A(3, 5)   ; B(6,-7)

Let's find the slope of AB = \dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\

                                         =\dfrac{-7-5}{6-3}\\\\=\dfrac{-12}{3}\\\\= - 4

m = -4

Slope of the perpendicular line to AB = -1/m = \dfrac{-1}{-4}=\dfrac{1}{4}

The perpendicular line of AB is bisector also. So, it goes through the midpoint of AB

Midpoint of AB = (\dfrac{x_{1}+x_{2}}{2}, \dfrac{y_{2}-y_{1}}{2})

                         =(\dfrac{3+6}{2},\dfrac{5+(-7)}{2})\\\\=(\dfrac{9}{2},\dfrac{-2}{2})\\\\=(\dfrac{9}{2},-1)

Equation of require perpendicular line: y - y1 = m (x -x1)

(x_{1},y_{1})= (\dfrac{9}{2},-1)\\ \\m =\dfrac{1}{4}\\\\y-[-1]=\dfrac{1}{4}(x-\dfrac{9}{2})\\\\y+1=\dfrac{1}{4}x-\dfrac{1}{4}*\dfrac{9}{2}\\\\y=\dfrac{1}{4}x-\dfrac{9}{8}-1\\\\y=\dfrac{1}{4}x-\dfrac{9}{8}-\dfrac{8}{8}\\\\y=\dfrac{1}{4}x-\dfrac{17}{8}

Answer:

Step-by-step explanation:

Perpendicular means that the slopes of the "old" line and the "new" line are opposite reciprocals; bisector means that the "new" line goes directly through the center of the "old" line. This perpendicular bisector, then, will go directly through the center of the "old" line, cutting it directly in half and leaving in its wake a 90 degree angle. To write this equation, then, of the perpendicular bisector, we need the slope of the old line and the midpoint of the old line. Let's work on the midpoint first:

M=(\frac{3+6}{2},\frac{5-7}{2})\\M=(\frac{9}{2},\frac{-2}{2})\\M=(\frac{9}{2},-1) So the "new" line will go through this point.

Onto the slope:

m=\frac{-7-5}{6-3}\\m=\frac{-12}{3}so the slope is

m = -4. That means that the perpendicular slope is

m=\frac{1}{4} Now we're ready to write the equation:

y-5=\frac{1}{4}(x-3) and

y-5=\frac{1}{4}x-\frac{3}{4}\\y=\frac{1}{4}x-\frac{3}{4}+\frac{20}{4} and finally,

y=\frac{1}{4}x+\frac{17}{4}

Answer:

A. 48

B. 24

C. C

Step-by-step explanation:

To divide up whole numbers by fractions, you simply need to just multiply the whole number by the reciprocal of the fraction. in other words, flip the fraction.

Ex.

12 ÷ 1/4

=

12 x 4

Ex. 2

12 ÷ 1/2

=

12 x 2

You have 3 number
Dominik [7]

Answer:

2

Step-by-step explanation:

The last number is 2

You calculate this by the only way the mean can be 4 is if the 3 numbers= up to 12. so 9 + 1=10 and if were looking for 12 we need 2 more so 2.

10 + 2=12

When dealing with mean you calculate the sum of all the number(check) then divided by the total of numbers so 3

12 divided by 3=4 and 4= your mean

Hope it helps have a great day:)

Paul bought 2.25 meters of wood to make 5 shelves of equal length . What is the length of each shelf ? show your work on a picec
LiRa [457]

Answer:

Length of each shelf is 0.45 meters

Step-by-step explanation:

Given

Total\ Length = 2.25\ meters

Shelves = 5

Required

Determine the length of each shelf

This is calculated by dividing the total length by number of shelves as thus:

Length = Total\ Length/Number\ of\ Shelf

Length = 2.25m /5

Length = 0.45m

Hence;

<em>Length of each shelf is 0.45 meters</em>
