What steps would i use to find the distance between the points (20, -4) and (-4, 3)

1 answer:

8 0

Distance formula = sqrt ((x2 - x1)^2 + (y2 - y1)^2)
(20,-4)...x1 = 20 and y1 = -4
(-4,3)...x2 = -4 and y2 = 3
now we sub
d = sqrt ((-4 - 20)^2 + (3 - (-4)^2)
d = sqrt ((-24^2) + (7^2))
d = sqrt (576 + 49)
d = sqrt 625
d = 25 <==

How to put -7/9 and -4/9 and 1/9 and 1/2 on a number line from least to greatest

WARRIOR [948]

Step-by-step explanation:

Take the LCM of the denominators:

=> LCM = 18

=> -7/9 x 2/2 = -14/18

=> -4/9 x 2/2 = -8/18

=> 1/9 x 2/2 = 2/18

=> 1/2 x 9/9 = 9/18

When the number is negative, the greater the number, the smaller it is.

So, -14 is smaller than -8.

< = smaller than

=> -14/18 < -8/18 < 2/18 < 9/18

=> -7/9 < -4/9 < 1/9 < 1/2

Need help with this math question

Hoochie [10]

Answer:

x = 3.1 ft

Step-by-step explanation:

Use Pythagoras' Theorem to find the base of the triangle. The base of the triangle is half of 'x'. Let's call the base 'y' for now.

To find 'y' we must use this formula,

$y^{2} = c^{2} -b^{2}$

'c' is the hypotenuse, the longer side, and 'b' is the other short side.

Sub in the numbers for 'c' and 'b',

$y^{2} = 2.1^{2} -1.4^{2}$

= 2.45

Square root both sides to get 'y' by itself,

y = 1.5652.....

Remember that 'y' is half of x? Simply multiply 'y' by 2 to get an answer for 'x',

x = 1.5652.... x 2

= 3.1 ft (1 d.p. nearest tenth)

Hope this helped!!
