Answer:

The green would take 4 and the blue would take 16 times respectivly. I did it by finding the volumes of the cups in terms of pi, then dividing it by the volume of the sink.

Step-by-step explanation:

So the volume of the whole half sphere is 512pi.

Now we have to find the volumes of the cup.

Equation: $\pi r^2h$

Blue cup:

$\pi 2^2(8)\\\pi 4(8)\\\pi 32$

It would take 16 times to drain it completly.

Green cup:

$\pi 4^2(8)\\\pi 16(8)\\\pi 128$

It would take 4 times to drain it completly.

Determine whether the sequence converges or diverges. If it converges, find the limit. (If an answer does not exist, enter DNE.)

In-s [12.5K]

Answer:

The sequence diverges.

Step-by-step explanation:

A sequence $a_{n}$ converges when $\lim_{n \rightarrow \infty} a_{n}$ is a real number.

In this question, the sequence given is:

$a_{n} = 4n\cos{(7n\pi)}$

The cosine is always going to be between -1 and 1, so for the convergence of the sequence, we look it as: $a_{n} = 4n$ . So

$\lim_{n \rightarrow \infty} a_{n} = \lim_{n \rightarrow \infty} 4n = \infty$

Since the limit is not a real number, the sequence diverges.

4. (07.04 MC)

timofeeve [1]

Answer:

11779 ft

Step-by-step explanation:

We are given that

$\theta=23^{\circ}$

Distance between tower and plane,d=5000 ft

We have to find the distance between the plane and bird.

Let x be the distance between bird and plane

We know that

$tan\theta=\frac{perpendicular\;side}{Base}$

Using the formula

$tan23=\frac{5000}{x}$

$x=\frac{5000}{tan23}=11779.3 \approx 11779ft$

Hence, the distance between the plane and bird=11779 ft
