Answer:
5/6 minutes x 60 = 50
1/3 minutes x 60 = 20
I got my answer by multiplying by 60 since there are 60 min in one hour.
Using the keyword 'of" it means to multiply so multiply your two given numbers.
Answer:

Step-by-step explanation:
By the Pythagorean theorem, triangle BCD has

and triangle ABD has
.
Substituting the first equation into the second equation for
gives the equation

Now triangle ABC has

Expanding out the left side,
.
Now substitute the equation from before,
, into the new equation.


We work to isolate
by adding
to both sides of equation and subtracting
from both sides.

Divide both sides by 2 and you get 
Assume that x is positive and square root both sides to get the final result of

To find

, we find the first few derivatives and observe the pattern that occurs.

As can be seen above, it can be seen that the continuos derivative of sin (x) is a sequence which repeats after every four terms.
Thus,

Therefore,

.
I think it would be (-y) to the power of -4. The exponents would add together to equal -4 while the y would just stay the same.
