Answer:
cos theta=-1/2
theta=cos-¹(-1/2)=120
tan theta=tan 120=-√3
sin theta=sin120=√3/2
cos(- theta)=cos theta=cos 120=-1/2
Answer:
Step-by-step explanation:
Given that water leaks from a vertical cylindrical tank through a small hole in its base at a rate proportional to the square root of the volume of the water remaining. The tank intitially contains 300 liters and 23 liters leak out during the first day
Let V represent the volume at time t.
Rate of change of V is 
where k represents the constant of proportionality
We separate the variables and integrate

Use the fact when t =0, V =300

Now use the fact when t =1 V= 300-23 = 277

k is negative because there is leak
So equation is

Using this
A) when half empty V = 150
t = 
so it takes 3.75 days
B) When t =3
V = 233.7515

Step-by-step explanation:
It is correct to state that a bit can be in one of 2 states, either 1 or 0.
<h3>What is a bit?</h3>
A bit is is a single binary digit. A bit can either be "1" or "0".
<h3>What is the explanation to the above answer?</h3>
We stated that It is correct to indicate that a bit can be in one of 2 states, either 1 or 0. This indicates that 2ⁿ strings must be created in total. The string must then be processed twice.
- The first time, for generation and
- The second for reading.
Hence, Our time is now O(2ⁿ⁺¹) = O(2ⁿ)

Answer: 55°
Step-by-step explanation:
∠YAZ + ∠YAX = 180° because they are linear pairs
∠YAZ + ∠YAX = 180°
∠YAZ + 125 = 180
Subtract both sides by 125
∠YAZ = 55°
