15. In a parallelogram ABCD, AB = 7.2 cm and the perpendicular from C on AB is 4.5 cm find its area.​

Answers

Answer 1

Answer:

32.4 cm²

Step-by-step explanation:

Given the parallelogram ABCD ; with AB = 7.2 cm

Perpendicular from C on AB is the height of the parallelogram = 4.5 cm

Using the relation fir the area of a parallelogram :

Area of a parallelogram = base * height

Area of a parallelogram = 7.2 cm * 4.5cm

Area of parallelogram = 32.40cm²

Hence, Area of parallelogram is 32.4 cm²

Next, choose a ratio other than 2 : 3, and divide using the selected ratio. Repeat the steps from questions 1 through 4 for the new line segment and ratio. Show your work. When you are finished, take a screenshot with the distances displayed on the divided line segment and paste it below your work.
Urgent!!! PLEASE HELP!!!

Answers

Answer:

hope this displays, sorry if it doesn't

Step-by-step explanation:

If we take (1,2) and (2,4) then the slope will be 2. and is we change it to (3,5) and (8,8) then slope will be 3/5.

What is slope?

The slope is the vertical distance which is calculated by ratio of difference between y coordinates and x coordinates.

How to find slope?

The formula of slope is (y2-y1)/(x2-x1).

Points A and B are (1,2) and (2,4) then slope=4-2/2-1=2

Length of line will be [tex]\sqrt{(4-2)^{2} +(2-1)^{2} }[/tex]

=[tex]\sqrt{4+1}[/tex]

=[tex]\sqrt{5} units[/tex]

Change the points to (3,5) and (8,8)  slope becomes=8-5/8-3=3/5

length of line will be [tex]\sqrt{(8-5)^{2} +(8-3)^{2} }[/tex]

=[tex]\sqrt{9+25}[/tex]

=[tex]\sqrt{34}[/tex] units.

let the ratio be 2:9

If we select this and divide using 2:9 then it will become 2:9.

Write an equation in slope-intercept form of the line going through the points (-1,6)
and (5, 0).

Answers

Answer:

Equation in slope-intercept form : y = -1x + 5

Step-by-step explanation:

Given points are:

(-1, 6) and (5,0)

We will first find the slope.

[tex]m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{0-6}{5-(-1)}\\\\m = \frac{-6}{6}\\m = -1[/tex]

The general equation for slope intercept form is;

y = mx + b

Now we will find the value of b by putting one of the points in the general equation

Putting (5,0)

0 = -1(5) + b

0 = -5 + b

b = 5

The equation in slope intercept form is;

y = -1x + 5

Hence,

Equation in slope-intercept form : y = -1x + 5

Similar triangles have their side lengths proportional by a constant scale factor. They also have all of their internal angles congruent, or with the same measure.

This means that the marked angles are equal:
