Answer:

All the trigonometric ratios are mentioned and the value of x = 51.32°

Step-by-step explanation:

we are given the value of cosx = $\frac{5}{8}$

We have to find all the other 5 trigonometric values.

sinx = $\sqrt{1-cos^{2}x }$ = $\sqrt{1-(\frac{5}{8})^{2} }$

= $\sqrt{\frac{39}{64}} = \frac{\sqrt{39}}{8}$

tanx = $\frac{sinx}{cosx}$ = $\frac{\sqrt{39} }{5}$

cosecx = $\frac{8}{\sqrt{39} }$

secx = $\frac{8}{5}$

cotx = $\frac{1}{tanx}$ = $\frac{5}{\sqrt{39} }$

These are the values of the trigonometric functions.

cosx = $\frac{5}{8}$

x = $cos^{-1} \frac{5}{8}$

x = 51.32°

The other acute angle = 90 - 51.32 = 38.68°

Using the distributive property of multiplication for 12:(8+7) we get

gizmo_the_mogwai [7]

Answer: 180

Step-by-step Explanation:
The first thing you need to do is know what order to go in, for example ‘pemdas’. (Parentheses, exponents, multiplication, division, additions, and subtraction.)
The first step is going to be the parenthesis so, 8 + 7 = 15. The second step is going to be to distribute, which is multiplication so,
12 x 15 = 180. The last step is to make sure you went through ‘pemdas’ all of the way.

All things being equal; demand decreases, as price increases.

The quantity supplied when price is $4 is 28

From table 4.4 (see attachment).

When price = $4, we have the following supplies:
