Answer:
11.53 degrees.
Step-by-step explanation:
ok so we know the hyp and opp sides. this means that it is sin. according to SOHCAHTOA we do sin^-1(2/10). you should get 11.53
Answer:
Also 10
Step-by-step explanation:
This type of triangle has two sides of equal length
$728.00 I’m assuming. Because the equation should be A(t)= P(1+i) ^t right? Telling us that P= principal, i= interest & t= time.
I’m assuming from MY financial mathematics class.

Answer:
Light is moving at the speed = 77.78 km/min
Step-by-step explanation:
Given:
Distance between island and point P = 5 km
Moving along the the shoreline when it is 1 km from P.
So, x = 1
From the above statement light makes seven revolutions per minute.
Therefore,
Solution:
From the given figure.

Substitute x = 1
-------------------(1)
Now, first we differentiate both side with respect to t.

Using chain rule.



Substitute
from equation 1.


Substitute 

Applying cross multiplication rule.


Therefore, light is moving along the shore at the speed of 77.78 km/min
