Answer:
Step-by-step explanation:
y = arctan(x+pi/2) use that tan y = x is y= arctan x
tan y = x+pi/2; change x with y and find y
tan x= y +pi/2; subtract pi/2 from both sides
-pi/2 + tan x = y
y= tan x -(pi/2) is the inverse function
you can also write it as
y = 1/2(2 tan x -pi)
We can conclude that the function evaluated in x = 5 is equal to 2.3150
<h3>How to evaluate the function?</h3>
Here we have the function:
And we want to evaluate in x = 5, this just means to replace the x by a 5 in the given function:
We can evaluate this with a calculator (as doing it by hand is kinda hard), we will get:
So we can conclude that the function evaluated in x = 5 is equal to 2.3150.

Answer:
The difference in the medians is about 1.5 hours.
The interquartile range for middle school students is 5, and the interquartile range for elementary school students is 3
Both sets of data have the same maximum and minimum values.

Answer:
Step-by-step explanation:
A direct variation suggest that the value of x in the equation would greatly affect the value of y such that when x is increasing, y also increases and the other way around. The equation for a direct variation is that,
y = kx
Substituting the given values in the ordered pair,
5 = k(4) ; k = 5/4
