What is the radian value of arccos(-3/sqrt(2))?
Ksju [112]

Answer:

Not defined over the real numbers

Step-by-step explanation:

Let

x = arc \cos( \frac{ - 3}{ \sqrt{2} })

This implies that:

\cos(x)  =  \frac{ - 3}{ \sqrt{2} }

This implies that:

\cos(x) =  - 2.12

The range of the cosine function is -1≤y≤1

Therefore

arc \cos( \frac{ - 3}{ \sqrt{2} })

is not defined for over the real numbers.

I need help work out 15% of 24
aleksandr82 [10.1K]

Hey!

-------------------------------------------------

Steps To Solve:

15% of 24

~Turn into decimal

15% = 0.15

~Multiply

0.15 * 24 = 3.6

~Check

3.6 / 24 = 0.15 * 100 = 15%

-------------------------------------------------

Hence, 15% of 24 is 3.6!

-------------------------------------------------

Hope This Helped! Good Luck!
