Answer:

29 inches

Step-by-step explanation:

For the following I just used trial and error and experimented with the possibilities:

29 inches - This is the only one that does not work.

30 inches - We can use 5 of the 6 inch trains, so this is possible.

31 inches - We can use 4 of the 6 inch trains and 1 of the 7 inch trains, so this is possible.

32 inches - We can use 3 of the 6 inch trains and 2 of the 7 inch trains, so this is possible.

33 inches - We can use 2 of the 6 inch trains and 3 of the 7 inch trains, so this is possible.

Instructions: Find the missing side lengths. Leave your answers as radicals in simplest form.

serg [7]

Given:

A figure.

To find:

The values of x and y.

Solution:

We know that, in a right angled triangle,

$\sin \theta =\dfrac{Perpendicular}{Hypotenuse}$

$\sin 60^\circ =\dfrac{x}{16}$

$\dfrac{\sqrt{3}}{2} =\dfrac{x}{16}$

Multiply both sides by 16.

$\dfrac{\sqrt{3}}{2}\times 16=\dfrac{x}{16}\times 16$

$8\sqrt{3}=x$

And,

$\cos \theta =\dfrac{Base}{Hypotenuse}$

$\cos 60^\circ =\dfrac{y}{16}$

$\dfrac{1}{2}=\dfrac{y}{16}$

Multiply both sides by 16.

$\dfrac{16}{2}=y$

$8=y$

Therefore, the missing side lengths are $x=8\sqrt{3}$ and $y=8$ .

Geometric sequence or whatever

sladkih [1.3K]

Step-by-step explanation:

An = -2 * An-1

What this means is that you multiply -2 to the term to get the next term.

Since our 1st term (A1) is -2, we have:

A2 = -2 * A1 = -2 * (-2) = 4,

A3 = -2 * A2 = -2 * (4) = -8,

A4 = -2 * A3 = -2 * (-8) = 16,

A5 = -2 * A4 = -2 * (16) = -32,

A6 = -2 * A5 = -2 * (-32) = 64.

Hence our first 6 terms in the GP are

-2, 4, -8, 16, -32 and 64.
