Using the formula a² + b² = c² but reversing it to c² - b² = x² where x replaces the a for comprehension reasons

so this is the formula
c² - b² = x²

insert the numbers on the triangle in the picture
21² - 8² = 377

since 377 is squared and not the side length, we need to square root it to find x
√377 = 19.4~

Answer: x = 19.4

The horizontal line segment at the top of the polygon on the grid below is how many units long?​
Ymorist [56]

Answer:

6 units long.

Step-by-step explanation:

Given:

A polygon drawn on a graph.

In order to determine the distance of the horizontal line at the top, we find the coordinates of the end points and then use distance formula to find the exact distance.

Let us label the polygon as ABCD as shown below. AB is the length of the horizontal line.

Coordinates of A are (x_1,y_1)=(-3, 4) as seen in the graph.

Coordinates of B are (x_2,y_2)=( 3, 4) as seen in the graph.

Now, distance formula  for two points (x_1,y_1)\ and\ (x_2,y_2) is:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d_{AB}=\sqrt{(3-(-3))^2+(4-4)^2}\\d_{AB}=\sqrt{(3+3)^2+0}\\d_{AB}=\sqrt{36}=6\ units

Therefore, the horizontal line at the top is 6 units long.

A family swimming pool holds 61 m3 of water. It loses 0.27m3 of water to evaporation each day. This situation can be represented
Bezzdna [24]

Answer:

The answer to your question is: when x = 100 days, y = 34 m³

Step-by-step explanation:

Data

Volumen = 61 m³

Loses 0.27 m³ each day

Equation    y + 0.27x = 61

when x = 100, y = ?

Process, just substitute x in the equation and solve it for y

                  y + 0.27(100) = 61

                  y + 27 = 61

                  y = 61 - 27

                  y = 34 m³

It means that after ten days, the swimming pool will only have 34 m³, because 27 m³ will have evaporated.
