The given line segment has a midpoint at (3,1)

masya89 [10]

Answer:

$y=\frac{1}{3}x$

Step-by-step explanation:

We have been given an image of a line segment and we are asked to find the equation of perpendicular bisector of our given line segment in slope-intercept form.

Since we know that the slope of perpendicular line to a given line is negative reciprocal of the slope of the given line.

Let us find the slope of our given line using slope formula.

$\text{Slope}=\frac{y_2-y_1}{x_2-x_1}$ , where,

$y_2-y_1$ = Difference between two y-coordinates,

$x_2-x_1$ = Difference between two x-coordinates of same y-coordinates.

Upon substituting the coordinates of points (2,4) and (4,-2) in slope formula we will get,

$\text{Slope}=\frac{-2-4}{4-2}$

$\text{Slope}=\frac{-6}{2}$

$\text{Slope}=-3$

Now we will find negative reciprocal of $-3$ to get the slope of perpendicular line.

$\text{Negative reciprocal of }-3=-(-\frac{1}{3})=\frac{1}{3}$

Since point (3,1) lies on the perpendicular line, so we will substitute coordinates of point (3,1) in slope-intercept form of equation $(y=mx+b)$ .

$1=\frac{1}{3}\times 3+b$

$1=1+b$

$1-1=1-1+b$

$b=0$

Therefore, the equation of perpendicular line will be $y=\frac{1}{3}x+0=\frac{1}{3}x$ and option A is the correct choice.

Hannah says that 2.11 is a rational number.Gus says that 2.11 is a repeating decimal.Who is correct and why?

irina [24]

According to Hannah 2.11 is a rational number.

According to Gus 2.11 is a repeating decimal.

Please see..

2.11 don't have more dots after two ones after decimal.

<em>If it would be a repeating decimal, it should be look like this 2.11......</em>

<em>2.11 could be expressed as rational number 211/100.</em>

<h3>Therefore, Hannah is absolutely correct by saying hat 2.11 is a rational number.</h3>

Find the surface area and the volume of the figure <br> Round to the nearest tenth if needed.

elixir [45]

Answer:

See below

Step-by-step explanation:

<u>Surface area:</u>

S = 2(lw + lh + wh) + 2πrh
S = 2(9*4 + 9*5 + 4*5) + 2*3.14*2*3 = 239.7 cm² (rounded)

<u>Volume:</u>

V = lwh + πr²h
V = 9*4*5 + 3.14*2²*3 = 217.7 cm³ (rounded)

9. Plot the points A (-2,3), B(2,-3), C(2,3) ,D(-2,3) join the points and find the distance between each point.

pav-90 [236]

Answer:

AB=7.21 unit

BC=6 unit

CD=7.21 unit

AD= 6 unit

AC=4 unit

BD=4 unit

Step-by-step explanation:

Coordinates of A =(-2,3)

Coordinates of B = (2,-3)

Coordinates of C = (2,3)

Coordinates of D =(-2,-3)

Distance formula : $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$A=(x_1,y_1)=(-2,3)\\B=(x_2,y_2)=(2,-3)\\AB = \sqrt{(2+2)^2+(-3-3)^2}$

AB=7.21 unit

$B=(x_1,y_1)=(2,-3)\\C=(x_2,y_2)=(2,3)\\BC=\sqrt{(2-2)^2+(3+3)^2}$

BC=6

$C=(x_1,y_1)=(2,3)\\D=(x_2,y_2)=(-2,-3)\\CD=\sqrt{(-2-2)^2+(-3-3)^2}$

CD=7.21

$A=(x_1,y_1)=(-2,3)\\D=(x_2,y_2)=(-2,-3)\\AD=\sqrt{(-2+2)^2+(-3-3)^2}$

AD=6

$A=(x_1,y_1)=(-2,3)\\C=(x_2,y_2)=(2,3)$

$AC=\sqrt{(2+2)^2+(3-3)^2}$

AC=4

$B=(x_1,y_1)=(2,-3)\\D=(x_2,y_2)=(-2,-3)$

BD= $\sqrt{(-2-2)^2+(-3+3)^2}$

BD=4
