Answer:

First graph (see below)

Step-by-step explanation:

The graph of the arctan(x) is the first graph attached, see below. This is because if you were to plug in the equation in any TI calculator, you would get this graph.

In a data set with a range of 55.4 to 105.4 and 400 observations, there are 176 observations with values less than 86. Find the
IrinaVladis [17]

<u>ANSWER: </u>

In a data set with a range of 55.4 to 105.4 and 400 observations.86 lies in the 49th percentile.

<u>SOLUTION: </u>

Given, in a data set with a range of 55.4 to 105.4 and 400 observations.

There are 176 observations below the value of 86, and we need to find the percentile for 86.

We know that, percentile formula = \frac{\text {number of observations below the required number}}{\text {total number of observations}} \times 100

Percentile of 86 = \frac{176}{400} \times 100

Since, we cancelled 400 with 100 we get 4 , hence above expression becomes,

=\frac{176}{4} = 49

So, percentile of 86 = 49

Hence, 86 lies in the 49th percentile.

A roller coaster car is going over the top of a 13-mm-radius circular rise. At the top of the hill, the passengers "feel light,"
aalyn [17]

Answer:

<em>0.253 m/s</em>

<em></em>

Step-by-step explanation:

radius r of the circular rise = 13 mm = 0.013 m

apparent weight loss = 50%

acceleration of the new weight = 0.5 x 9.81 = 4.905 m/s^2

centripetal acceleration = 9.81 -  4.905 =  4.905 m/s^2

centripetal acceleration = \frac{v^{2} }{r}

where v is the acceleration at the rise and r is the radius of the rise

centripetal force = \frac{v^{2} }{r}  = \frac{v^{2} }{0.013}

4.905 = \frac{v^{2} }{0.013}

v^{2} = 0.063765

v = \sqrt{0.063765} = <em>0.253 m/s</em>

We can use algebraic operations to rewrite expressions, including polynomial expressions. When we rewrite polynomial expressions
Salsk061 [2.6K]

Similar transformations to the application of algebraic operations to rewrite expressions that form representations that appear different from their parent expressions, can be seen in the following fields;

Geometry; Rigid transformations such as rotation, can transform a rectangle to appear to look like a kite

Physics; The heating of a liquid, can transform its physical state from liquid to gas, however, the gas formed by heating the liquid represent the same material chemically
