Equate what is inside cosine with $2\pi$ , base period and solve for x,

$2\pi=\frac{\pi}{3}x$

$6\pi=\pi x$

$\boxed{x=6}$

Hope this helps :)

Step-by-step explanation:

14÷2=7

18÷2=9

for the first equation

14/y=7

cross multiply will be

7y=14

Find the missing dimension use the scale factor 1:12 model 32 cm find the actual in m

gizmo_the_mogwai [7]

Given:

The scale factor is 1:12.

Dimension of model = 32 cm

To find:

The actual dimension in m.

Solution:

Let x be the actual dimension.

The scale factor is 1:12 and the dimension of model is 32 cm.

$\dfrac{1}{12}=\dfrac{32}{x}$

On cross multiplication, we get

$x=32\times 12$

$x=384\ cm$

$x=3.84\ m$ $[\because 1\ m=100\ cm]$

Therefore, the actual dimension is 3.84 m.
