A Parallelogram whose vértices have coordinates r(1,-1) s(6,1) t (8,5) u 3,3 have a shorter diagonal

Mathematics

lara [203]3 years ago

Answer:

The two shortest diagonals seems to be RU and TS. A further explanation is provided below.

Step-by-step explanation:

The given coordinated are:

r = (1, 1)

s = (6, 1)

t = (8, 5)

u = (3, 3)

Now,

The distance between RU will be:

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

On putting the values, we get

= \sqrt{(3-1)^2+(3+1)^2}

= \sqrt{(2)^2+(4)^2}

= \sqrt{4+16}

= \sqrt{20}

PLEASE HELP!
emmainna [20.7K]

Use the given recursion and starting value of x_0 = 2.4 to find x_1 :

x_1 = \dfrac{x_0 + \frac6{x_0}}2 = \dfrac{2.4 + \frac{6}{2.4}}2 = 2.45

Do the same for x_2 and x_3 :

x_2 = \dfrac{x_1 + \frac6{x_1}}2 = \dfrac{2.45 + \frac6{2.45}}2 \approx 2.44949

x_3 = \dfrac{x_2+\frac6{x_2}}2 \approx \dfrac{2.44949 + \frac6{2.44949}}2 \approx \boxed{2.44949}

(That's not a mistake. This just tells you that the 2nd and 3rd iterates are very close together and have at least the same first 5 digits after the decimal.)

Hmm who is smart enough for this :)
Goryan [66]

Answer:

1

-\frac{9}{15}

-0.7

Step-by-step explanation:

Both -\frac{9}{15} and -0.7 are negative so therefore, 1 is the greatest

-\frac{9}{15} is -0.6 which is greater than -0.7 so it's the 2nd greatest

and -0.7 is the least

(3x - 2) + (5x + 7)​
deff fn [24]

Answer:

8x+5

Step-by-step explanation:

To solve this, you need to combine the like terms. The line terms are 3x +5x and -2+7. 3x+5x=8x and 7-2 (same thing as -2+7) is positive 5 so its 8x+5
