The Doppler effect allows finding the answer for the blue shift of some stars is:
The star closing in on us
The Doppler effect is the change in the frequency perceived by the relative movement of the emission and the receiver, in the case of light we must use relativistic relations and the expression is
[tex]f = f_o \sqrt{\frac{1- \frac{v}{c} }{1+ \frac{v}{c} } }[/tex]
Where f and fo are the observed and emitted frequencies, respectively, c the speed of light and v the relative speed between the source and the observer, this speed is positive if they move away and negative if they approach.
The speed light is related to frequency and wavelength
c = λ f
[tex]f = \frac{c}{ \lambda}[/tex]
we substitute
[tex]\frac{1}{\lambda } = \frac{1}{lam_o } \ \sqrt{\frac{1- \frac{v}{c} }{1+ \frac{v}{c} } }[/tex]
[tex]\lambda = \lambda_o \ \sqrt{ \frac{1+ \beta }{1- \beta } }[/tex]
with [tex]\beta = \frac{v}{c}[/tex]
The magnitude of β is always less than 1
Let's analyze the effect of the speed between the observer and the emitter on the perceived wavelength, we have two:
The two bodies are moving away, in this case the velocity is positive, let's substitute[tex]\lambda_1 = \lambda_0 \ \sqrt{\frac{1+| \beta|}{1- |\beta|} }[/tex]
We can see that the numbering of the root increases and the dominated decreases, so the root increases its value, consequently
[tex]\lambda_1 > \lambda_o[/tex]
This process is called redshift.
The two bodies are approaching, in this case the velocity is negative, we substitute
[tex]\lambda_2 = \lambda_o \ \sqrt{\frac{1- |\beta| }{1+ |\beta| } }[/tex]
We see that the root decreases its value, consequently
[tex]\lambda_2 < \lambda_o[/tex]
This is called the blueshift.
In this exercise, indicate that we have a blueshift, which is why the star is approaching us.
In conclusion, using the Doppler effect we can find the answer for the blue shift of some stars is:
The star closing in on us

The average rate of change of the function y = cos(2x) over the interval (0, π/2) is [tex] \frac{-4}{\pi}[/tex]
The average rate of change over a given interval is defined thus :
[tex] R = \frac{f(b) - f(a)}{b - a}[/tex] Where a and b are the interval valuesAt a = 0 :

let f be the function defined above, where c and d are constants. if f is differentiable at x = 2 what is the value of c + d?
Answer: The values for the constants are c=2, and d=-4.
explanation: We have the function f, defined as:
and
where c and d are constants.
So, if f is differentiable at x=2, then it must be continuos at x=2, therefore
Let's call this, equation 1.
On the other hand, we have that f is differentiable, therefore
and
so, we calculate
which, replacing in equation 1, gives us
Finally, the answer is that c=2, and d=-4.
The constants have the values c=2 and d=-4.
What is constants?A constant is an identifier (name) for a simple value. As the name suggests, that value cannot change during the execution of the script (except for magic constants, which aren't actually constants). Constants are case-sensitive.
A constant in computer programming is a value that should not be changed by the program while it is running normally, i.e., the value is constant.
Although the phrases "constant" and "named constant" are frequently used interchangeably, a constant is said to be "named" when it is connected to an identifier.
Therefore, The constants have the values c=2 and d=-4.
