Answer:
The pantograph is spring-loaded and pushes a contact shoe up against the underside of the contact wire to draw the current needed to run the train. As the train moves, the contact shoe slides along the wire and can set up standing waves in the wires which break the contact and degrade current collection.

*How much money was in Caroline's account when it was opened? Explain.
*After 2 years, how much money would Caroline have saved? (Hint - convert years to months before solving). To earn full credit, show your work using a method explained in the Orientation.
Answers
Answer:
A) $3100
B) $6700
Step-by-step explanation:
A)The first table entry is the value of the opening balance of Caroline's account.
$3100 was in Caroline's account when it was opened.
__
B)After 1 month, the balance in Caroline's account increased by $3250 -3100 = $150. There are 12 months in a year, so after 2 years, Caroline will have made 12×2 = 24 additional deposits of $150. Her account value will be ...
24 × monthly deposit + initial balance
= 24 × $150 + $3100 = $3600 +3100 = $6700
Caroline would have saved $6700 after 2 years.

objectivity in the interpretation of data is referred to as
Answers
In philosophy, objectivity is a central concept that generally denotes an objective and impartial approach to something. The opposite is subjectivity.
That something is objectively true, an objective truth, means that it is true regardless of subjectivity. Objectivity is usually an ideal in connection with research, as the result is expected to be as independent of the researcher's opinions or ideas as possible.
Objectivity is often also emphasized as a basic ideal in journalistic work. An important question in philosophy is whether it is possible to experience something objectively.

1. Find the x and y intercept for the function 3x-4y=12
Answers
Step-by-step explanation:
To easily solve this problem we need to know two facts:
the y-intercept is 'c' when a line is in the slope-intercept form (y = mx + c)the x-intercept occurs when y = 0Slope-intercept form
Since 3x - 4y = 12
3x - 12 = 4y
y = ³/₄ x - 3
∴ y-intercept is (0, -3)
Solve for x when y = 0
Since 3x - 4y = 12
3x - 4(0) = 12
x = 4
∴ x-intercept is (4, 0)
We can check our answer by graphing the line and seeing if it passes through the intercepts we calculated. Since it does (see graph below), then the answers we calculated are correct.

After the first hour, it would cost 3 dollars to rent children’s skates. After the second, it would cost 6. This would make the slope 3, so the formula would be C=3h. It costs $3 per hour to rent children’s skates.
If the question is referring to the grey points, it would cost more to rent children’s skates for the first hour. After the first hour, it would cost more to rent adults skates.
The starting value (the y-intercept/the point at zero on the y axis, which is the vertical center line) is 6, and the slope is still 3 for the children’s skates.
For the first hour, it would cost $9 for children’s skates and $8 for adults skates. For two hours, it would cost $12 for the children’s skates and $16 for adults skates.

Lucy can type 300 words in 5 minutes. How many words can Lucy type in 27 minutes?
Answers
Answer:
1620 wordsStep-by-step explanation:
Given,
Number of words Lucy can type in 5 minutes
= 300 words
So,
Number of words Lucy can type in 1 minute
[tex] = \frac{300}{5} \: words[/tex]
= 60 words
Therefore,
Number of words Lucy can type in 27 minutes
= (60 × 27) words
= 1,620 words
Hence, Lucy can type 1620 words in 27 minutes.

Answer:

variable
Step-by-step explanation:
1st Rate of change is 18 - 0 / 0.5 - 0 = 18/0.5 = 36
2nd rate of change is 32 - 18 / 1.5 -0.5 = 14 / 1 = 14
3rd rate of change is 26 - 32 / 2 - 1.5 = -6/0.5 = -12
so the rates of change are variable

Answers
Answer:
10 m.
Step-by-step explanation:
We have a triangle with hypotenuse h m (the rope's length) and one leg 16 - 8 = 8 m and the other 6 m.
So h^2 = 8*2 + 6^2 = 100
h = 10 m.

Answer:
$55
Step-by-step explanation:
Since we are not given much information in this problem, we know this must be a pretty simple sequence. If we make a sequence of Natural Numbers and match it up to the prices we've been given, we get
1,2,3,4...
5,10,15...
The price is increasing by five dollars for every "n", so our sequence is just 5n. Extrapolating this out gives us $55 for n=11
