Answer:

d=\frac{\sqrt{97}}{6}\approx1.6415

Step-by-step explanation:

We have the two points: (2, 5/2) and (8/3, 1).

And we want to find the distance between them.

So, we can use the distance formula:

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

Let (2, 5/2) be (x₁, y₁) and let (8/3, 1) be (x₂, y₂). Substitute:

d=\sqrt{(\frac{8}{3}-2)^2+({1-\frac{5}{2})^2

Evaluate the expressions within the parentheses. For the first term, we can change 2 to 6/3. For the second term, we can change 1 to 2/2. So:

d=\sqrt{(\frac{8}{3}-\frac{6}{3})^2+({\frac{2}{2}-\frac{5}{2})^2

Evaluate:

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

Square:

d=\sqrt{\frac{4}{9}+\frac{9}{4}

Add. We can change 4/9 to 16/36. And we can change 9/4 to 81/36. So:

d=\sqrt{\frac{16}{36}+\frac{81}{36}}

Add:

d=\sqrt{\frac{97}{36}}

We can separate the square roots:

d=\frac{\sqrt{97}}{\sqrt{36}}

Simplify. So, our distance is:

d=\frac{\sqrt{97}}{6}\approx1.6415

How many times greater is The total area of Russia than the total area of Finland? Finland total area is 3.4 x 10 to the 5th pow
Luden [163]

Answer:

The answer to your question is Russia is 50 times greater than Finland.

Step-by-step explanation:

Data

Finland area = 3.4 x 10⁵ km²

Russia area = 1.7 x 10⁷ km²

Proportion = ?

Process

1.- Just divide the Russia's area by the Finland's area.

   Proportion = \frac{Finland's area}{Russia's area}

   Proportion = \frac{1.7 x 10^{7} }{3.4 x 10^{5} }

   Porportion = 50

Which choice shows the coordinates of C’ if the trapezoid is reflected across the y-axis?
suter [353]
A reflection through the axis and is given by the following transformation rule:
 (x, y) -------> (-x, y)
 We have the following point:
 C = (5, 3)
 Applying the transformation rule we have:
 (5, 3) -------> (-5, 3)
 Therefore, C' is given by:
 C '= (- 5, 3)
 Answer:
 (-5, 3)

The way i do it, is sort of like this :

Is 7 a factor of 42? 
  Is 5 a factor of 42? 

7 is a factor of 42. 
It must be in multiples of 7!

Therefore, we have 5 on the other side, which makes it 5 x 7 = 35
