Two lines are perpendicular when... the product of their slope is -1, the product of the slope is greater than 0, they have the
Soloha48 [4]

The answer is the product of their slope is -1.

First, let's break this down. Perpendicular lines are line with opposite reciprocal slopes. Opposite meaning the inverse sign and reciprocal meaning flipped.

For instance,

If a line had the slope of 5, its inverse would have a slope of -1/5.

Now, if we multiply these numbers together,

5 * -1/5 = -1

The 5's cancel out.

This works for any two perpendicular lines

Indicate a general rule for the nth term of the sequence a1 = 2 and r = √3.
pantera1 [17]

It is given in the question that,

a_{1} = 2, r = \sqrt 3

Since we have the value of r given, so we have to use the formula to find the nth term of the geometric progression, which is

a_{n} = a(r)^{n-1}

Substituting the values of a and r, we will get

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

So the correct option is the third option .

Sladkaya [172]

Answer: C. 70 percent

Step-by-step explanation:

Given, Time for the first unit = 50 minutes

Time for the second unit = 35 minutes

The unit improvement factor learning curve = (The time for the second unit) ÷ (time for the first unit) x 100.

So, The unit improvement factor learning curve  = 35÷ 50 × 100 = 70 percent.
