What is the distance of this line?<br><br>Which is the right answer?

Shtirlitz [24]

Answer:

Step-by-step explanation:

We can use the distance formula derived from the Pythagorean theorem

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

the two points given are

(0, 3) and (-2, -3)

$(x_2-x_1) = (0-(-2)) = 2\\(y_2-y_1) = (3-(-3)) = 6\\D = \sqrt{(2)^2 + (6)^2} \\D = \sqrt{4 + 36} \\D = \sqrt{40} = 6.324$

0.75 = 0.750<br> are they equal

Sliva [168]

Yes they are the same. The number on the right just has an extra zero. You can add an infinite amount of zeros to the end of a number without changing it's value.

Sec (a) + tan (a) = sec (a) – tan (a)

Mariulka [41]

Answer:

a = π n for n element Z

Step-by-step explanation:

Solve for a:

sec(a) + tan(a) = sec(a) - tan(a)

Subtract sec(a) - tan(a) from both sides:

2 tan(a) = 0

Divide both sides by 2:

tan(a) = 0

Take the inverse tangent of both sides:

Answer: a = π n for n element Z
