Answer:

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

Step-by-step explanation:

Given segment AB and point A with coordinates (x₁,y₁) and point B(x₂,y₂) as end points in the segment, the distance between the points forms the length of the segment AB and can be determined by the expression;

d=√ (x₂-x₁)² + (y₂-y₁)²

If 3t - 7 = 5t, then 6t =

STALIN [3.7K]

Answer:

-21 = 6t

Step-by-step explanation:

3t - 7 = 5t

Subtract 3t from each side

3t-7-3t = 5t-3t

-7 = 2t

Multiply each side by 3 to get 6t

-7*3 = 2t*3

-21 = 6t

How do the lengths of line segments define the golden ratio?

NISA [10]

Answer:

$\frac{a+b}{a}=\frac{a}{b}$

Step-by-step explanation:

The golden ratio is a special number favored by the Greeks. Its ratio roughly equals 1.618. The ratio is formed by taking a line segment and dividing it into two parts labeled a and b. The golden ratio is formed when this proportion is true $\frac{a+b}{a}=\frac{a}{b}$ .

When you add a and b then divide by a, it will be the same as a divided by b. This will hold true only for specific lengths of a and b. This means you must divide the line segment in such a way that a and b meet this requirement.

Example:

If the line segment is 50 cm long. Split the segment into parts a and b where a = 30.9 and b = 19.1. Substitute the values into the proportion $\frac{a+b}{a}=\frac{a}{b}$ .

$\frac{30.9+19.1}{30.9}=\frac{30.9}{19.1}$

$\frac{50}{30.9}=\frac{30.9}{19.1}$

1.618 = 1.618

This is the golden ratio.
