We are asked to give the exact value of cos(arcsin(one fourth)). In this case, we shift first the setting to degrees since this involves angles. we determine first arc sin of one fourth equal to 14.48 degrees. then we take the cos of 14.48 degrees equal to 0.9682. Answer is 0.9682.

Answer:

687

Step-by-step explanation:

Let f(x) = 8x^3 − 22x^2 − 4 and g(x) = 4x − 3. Find f(x) over g(x).

Alenkasestr [34]

You would use the long division technique..

Here it looks like:

 --------------------
4x − 3 | 8x^3 − 22x^2 − 4
---------
 |
 |
 |

and like that,,,

after you do this, you will get

$2x^2-4x-3-\frac{13}{4x-3}$

hope that helps

If m(x) = x+5/x-1 and n(x) = x — 3, have the same domain as (m • n) (x)

Yuri [45]

For this case we have the following functions:

$m (x) = \frac {x + 5} {x-1}\\n (x) = x-3$
