Two in-phase sources of waves are separated by a distance of 4.00m. these sources produce identical waves that have a wave length of 5.00m. on the line between them, there are two places at which the same type of interference occurs. 3) which type of interference occurs twice? constructive destructive 4) at what location from one of the sources does this interference occur? 0.5m and 3.5m 0.75m and 3.25m 1.5m and 2.5m 5) at what location from one of the sources does the other type of interference occur? 0.5m 1.0m 1.5m 2.0m a slit of width 4.30x10-5m is located 1.32m from a flat screen. light of wavelength 635nm is shining on the slit. 6) what is the width of the central bright fringe? .025m .039m .053m .067m

step-by-step explanation:

let's add {f(x)=x+1}f(x)=x+1 and {g(x)=2x}g(x)=2x together to make a new function.

f(x)+g(x) =(x+1)+(2x)=x+1+2x=3x+1

let's call this new function hh. so we have:

{h(x)}={f(x)}+{g(x)}{=3x+1}h(x)=f(x)+g(x)=3x+1

we can also evaluate combined functions for particular inputs. let's evaluate function hh above for x=2x=2. below are two ways of doing this.

method 1: substitute x=2x=2 into the combined function hh.

h(x)

h(2)

​    

=3x+1

=3(2)+1

=7

​ since h(x)=f(x)+g(x)h(x)=f(x)+g(x), we can also find h(2)h(2) by finding f(2) +g(2)f(2)+g(2).

first, let's find f(2)f(2):

f(x)

f(2)

​    

=x+1

=2+1

=3

​  

now, let's find g(2)g(2):

g(x)

g(2)

​    

=2x

=2⋅2

=4

​  

so f(2)+g(2)=3+4=\greend7f(2)+g(2)=3+4=7.

notice that substituting x =2x=2 directly into function hh and finding f(2) + g(2)f(2)+g(2) gave us the same answer!

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
