A line segment AB has the coordinates A (2,3) AND B ( 8,11) answer the following questions (1) What is the slope of AB? (2) What

Gnesinka [82]

Given:

Endpoints of a line segment AB are A(2,3) and B(8,11).

To find:

(1) Slope of AB.

(2) Length of AB.

(3) Midpoint of AB.

(4) Slope of a line perpendicular to AB.

Solution:

We have, endpoints of line segment AB, A(2,3) and B(8,11).

(1)

Slope of AB is

$m=\dfrac{y_2-y_1}{x_2-x_1}$

$m=\dfrac{11-3}{8-2}$

$m=\dfrac{8}{6}$

$m=\dfrac{4}{3}$

Therefore, the slope of AB is $\dfrac{4}{3}$ .

(2)

Length of AB is

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

$AB=\sqrt{(8-2)^2+(11-3)^2}$

$AB=\sqrt{(6)^2+(8)^2}$

$AB=\sqrt{36+64}$

$AB=\sqrt{100}$

$AB=10$

Therefore, the length of AB is 10 units.

(3) Midpoint of AB is

$Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)$

$Midpoint=\left(\dfrac{2+8}{2},\dfrac{3+11}{2}\right)$

$Midpoint=\left(\dfrac{10}{2},\dfrac{14}{2}\right)$

$Midpoint=\left(5,7\right)$

Therefore, the midpoint of AB is (5,7).

(4)

Product of slopes of two perpendicular lines is -1.

Let the slope of line perpendicular to AB be m₁.

$m_1\times \dfrac{4}{3}=-1$

$m_1=-\dfrac{3}{4}$

So, slope of line perpendicular to AB is $-\dfrac{3}{4}$ .

Can Someone answer this please

Vsevolod [243]

Answer:

So the scaling means that per every foot in real life, you have 2.4 centimeters, which means that the scale model would be 48 cm tall.

A. To find your answer, you would divide 48 by 1.2, which is 40. So your model would be 40 bottle caps tall

B. Same as A, all you have to do is divide 48 by 15.2, which would be about 3 popsicle sticks tall (rounded)

(Hope this helps)

Write the product as a mixed number.<br> 5 x 1 1/6

cupoosta [38]

Answer:

9 1/6

Step-by-step explanation:

multiplication of fractions

your 5 = 5/1

hence it will be 5/1 x 11/6 = 55/6

55 divided by 6 will be equal to 9 with one remainder

so your answer will be 9 1/6
