If cos(t) = <br> −<br> 1<br> 2<br> and tan(t) < 0, find sin(t) and cos(-t)

morpeh [17]

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

Water leaks from a vertical cylindrical tank through a small hole in its base at a rate proportional to the square root of the v

Cloud [144]

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 $\frac{dV}{dt} = k\sqrt{v}$

where k represents the constant of proportionality

We separate the variables and integrate

$\frac{dV}{\sqrt{v} } =kdt\\2\sqrt{V} =kt +C\\$

Use the fact when t =0, V =300

$2\sqrt{300} =C\\$

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

$2\sqrt{277} =k+2\sqrt{300} \\k = 2(-0.67719) = -1.3544$

k is negative because there is leak

So equation is

$2\sqrt{V} =-1.3544t+2\sqrt{300} \\V= (-0.6772t+\sqrt{300} )^2$

Using this

A) when half empty V = 150

t = $\frac{2\sqrt{150} -2\sqrt{300}}{-1.3544} \\=3.75$

so it takes 3.75 days

B) When t =3

V = 233.7515

Give the “best” big-oh notation to describe the complexity of the algorithm that prints all bit strings of length n.

artcher [175]

It is correct to state that a bit can be in one of 2 states, either 1 or 0.

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)

Pls help me with this problem!!!!

kolbaska11 [484]

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°

Hope that helped!
