A model train has a scale of 1 in : 3in. if the real train is 12ft tall then how tall is the model train
Gelneren [198K]

If the ratio of a model train to a real train exists 1:3 and the real train exists 12 feet then the model train exists 3 feet long.

<h3>How to estimate the ratio of the model train?</h3>

Given that the model train contains a scale of 1: 3 and the real train exists 12 feet tall.

The ratio indicates how many times one number has another number.

A ratio exists as the relationship in quantity between two things.

It conveys the quantity of one thing in words of another.

The ratio of a model train to a real train exists at 1 inch :3 inches.

Height of model train = 12 * 1/4

Height of model train = 3 inches

Therefore, the ratio of a model train to a real train exists 1: 3 and if the real train exists 12 feet then the model train exists 3 feet long.

Verify that -tan2x = (2tanx) / (sec^2x - 2)
sashaice [31]

Answer:

Below.

Step-by-step explanation:

- tan 2x =   -2tanx / (1 - tan^2x)

Using the identity  tan^2x = sec^2x - 1 and substituting for tan^2x:

- tan 2x = -2 tanx / (1 - (sec^2x - 1))

=   2 tanx / ( - 1(sec^2x + 2))

= 2 tan x / (sec^2 x - 2)
