Answer:

There's a treasure hunt called The amazing race this year I'll be participating with one other person. Her name is Fransterla as a result I will be the team leader. With this I will try my best to lead us to victory. The first task will be that they give us clues and a map, to find information for the journey that is up a head.

There's a seasonal show called the Amazing Race. I am chosen to participate in it, my partner is Fransteria. I am the leader of our team. In this game, we have to chose the best path, we have to calculate the fastest way to victory. A map full of triangles will be given to us for the first path. We will get to know about more details later.

when the temperature is 68 F, the speed of sound in air is approximately 343 meters per second. Approximately how many kilometer

Digiron [165]

Hello!

Since we are given that the speed of sound in the air travels about 343 meters per second, we can multiply 343 meters per second by 5, and then we convert the meters to kilometers.

343 · 5 = 1715 meters per 5 seconds.

1000 meters are equal to 1 kilometer. So, we can divide 1715 by 1000 to convert meters to kilometers.

1715 / 1000 = 1.715

Therefore, the speed of sound in air is about 1.715 kilometers per 5 seconds.

Write an equivalent series with the index of summation beginning at n = 1. ∞ (−1)n + 1(n + 1)xn n = 0

kkurt [141]

Looks like the starting series is

$\displaystyle\sum_{n=0}^\infty\left((-1)^n+1\right)(n+1)x^n$

Note the degree of the first few terms in the series, for $n=0,1,2$ , are $x^0,x^1,x^2$ , and so on.

So if the series were to start at $n=1$ , we would need to preserve that pattern, and we do that by replacing $n$ with $n-1$ :

$\displaystyle\sum_{n=1}^\infty\left((-1)^{n-1}+1\right)(n-1+1)x^{n-1}$

Simplifying a bit, we end up with

$\displaystyle\sum_{n=1}^\infty\left(1-(-1)^n\right)nx^{n-1}$

Part A: Sam rented a boat at $225 for 2 days. If he rents the same boat for 5 days, he has to pay a total rent of $480.

miss Akunina [59]

Answer:

Here's what I get.

Step-by-step explanation:

Part A. Equation in standard form

The question is asking you to find the equation of a straight line that passes through two points

Let x = the number of days

and y = the cost

Then the coordinates of the two points are (2,225) and (5,480).

(i) Calculate the slope of the line

$\begin{array}{rcl}m & = & \dfrac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\& = & \dfrac{480 - 225}{5 - 2}\\\\& = & \dfrac{255}{3}\\\\& = & 85\\\end{array}$

In other words, the daily rental is $85/day.

(ii) Calculate the y-intercept

$\begin{array}{rcl}y & = & mx + b\\480 & = & 85 \times 5 + b\\480 & = & 425 + b\\b & = & 55\\\end{array}$

(iii) Write the equation for the line

y = 85x + 55

That is, the cost is $55 plus $85/day

Part B. Equation in function notation

Replace y with ƒ(x)

ƒ(x) = 85x + 55

Part C. Graphing

Let's say you want to plot a graph of the rental cost for up to ten days.

(i) Calculate two points on the graph.

When x = 0, y = 85; when x = 10, y = 905.

(ii) Scale your axes

A good number of intervals is about ten.

Your x-axis should have tick marks at 1-day intervals.

Your largest y-value is 905. Ten intervals would make about $90/interval. However, you should round that up to $100/interval for easy interpolation.

Your y-axis will run from 0 to $1000 in $100 intervals.

Plot your two points and draw a straight line through them.

(iii) Axis labels

x represents the number of days, so the label on the x-axis could be "No. of days."

y represents the cost of renting the boat, so the label on the y-axis could be "Rental cost."

Your graph should resemble the one below.
