In a theater, there are 15 chairs in the first row, each row has 3 more chairs than the previous row, and there are 15 rows. how

Nimfa-mama [501]

The 1st row has 15 chairs.

The 2nd row has 15 + 3 = 18 chairs.

The 3rd row has 18 + 3 = 15 + 2•3 = 21 chairs.

The 4th row has 21 + 3 = 15 + 3•3 = 24 chairs.

The pattern continues, so that the n-th row has 15 + (n - 1)•3 = 3n + 12 chairs.

If there are 15 rows, then the total number of chairs is

$\displaystyle \sum_{n=1}^{15} (3n + 12) = 3 \sum_{n=1}^{15} n + 12 \sum_{n=1}^{15} 1 = 3\cdot\frac{15\cdot16}2 + 12\cdot15 = \boxed{540}$

where we use the formulas

$\displaystyle \sum_{n=1}^N 1 = N$

$\displaystyle \sum_{n=1}^N n = \frac{N(N+1)}2$

How does the structure of these poems differ? "digging" attempts to capture a moment in the distant past, while bashō's haiku sp

Dennis_Churaev [7]

While Digging goes from the present to the past, the haiku captures a specific moment.

<h3>What is the focus of Digging?</h3>

This is about family history and the way this affects the author as he compares his job as a writer to the job as a farmer his father used to have. In the fragment presented, the author is both describing the past and present in Where he was digging, because he goes from the action he is doing, which is writing to the one his father was doing many years ago, which is digging.

<h3>What is the focus of the Haiku?</h3>

This haiku or short poem focuses on describing a landscape by mentioning elements such as the moonflowers. This means there is not a change in time but the author focuses only on capturing a specific moment.

Note: This question is incomplete; here is the missing excerpt:

"Digging"

Till his straining rump among the flowerbeds

Bends low, comes up twenty years away

Stooping in rhythm through potato drills

Where he was digging.

Haiku by Bashō.

On the way to the outhouse—

the white of the moonflower

by torchlight.

Agata [3.3K]

Answer:

Many other power plants like coal-fired power plants have cooling towers or these large bodies of water as well. This similarity exists because the process of turning heat into electricity is almost identical between nuclear power plants and coal-fired power plants.

How can i graph the equation using the slope and the y intercept y=7/4x+2

Lelu [443]

Since you already have the equation, all you need to do is pick two values of x.

For example, when x = 0, you get y = 7/4(0) + 2 = 2. So the line passes through the point (0, 2). When x = 4 (picked to cancel the 4 in the fraction), you get y = 7/4(4) + 2 = 9, so the line also passes through the point (4, 9).

You can describe an entire line by any two points that it contains. So plot these two points, then connect the dots with a line passing through them both.

How can a parasite utilize multiple hosts

erica [24]

Parasites that use only a single host species in their life are called monoxenic; those with multiple hosts are called heteroxenic. ... intermediate hosts are all the others. Paratenic hosts are hosts that are used only for transport; no life cycle stages are completed within the host.
