D= 11/5(p-15)

solve for p.

Answers

Answer:  The required solution for p isp=(11+75D)/(5D).

Step-by-step explanation:  We are given to solve the following equation for the unknown variable p :

D=(11)/(5(p-15))~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

To solve the given equation for p, we must find the value of p in terms of D.

From equation (i), we have

D=(11)/(5(p-15))\n\n\n\Rightarrow D=(11)/(5p-75)\n\n\n\Rightarrow D(5p-75)=11\n\n\Rightarrow 5Dp-75D=11\n\n\Rightarrow 5Dp=11+75D\n\n\Rightarrow p=(11+75D)/(5D).

Thus, the required solution for p isp=(11+75D)/(5D).
D=11/5p-33
11/5p=D+33
p=5/11D+15

A sine function can be used to model light waves. Green light has a wave length, or period of about 520 nm. Which equation best models green light?A.) y=sin 260/pi theta

B.) y= sin pi/520 theta

C.) y= sin 520/pi theta

D.) y= sin pi/260 theta


Please help

Answers

Answer:

y = A sin (kx \pm wt)

Where k represent the number of wave k =(2\pi)/(\lambda) and w =(2\pi)/(T) represent the angular frequency with T the period.

For this case we know tha T = 520 nm

And the angular frequency would be given by:

w = (2\pi)/(520)= (pi)/(260)

So then the possible anwer for this case would be:

D.) y= sin pi/260 theta

Since is the only option with satisfy the general equation of a wave.

Step-by-step explanation:

Since the sine function can be used to model light waves we can use the following general expression:

y = A sin (kx \pm wt)

Where k represent the number of wave k =(2\pi)/(\lambda) and w =(2\pi)/(T) represent the angular frequency with T the period.

For this case we know tha T = 520 nm

And the angular frequency would be given by:

w = (2\pi)/(520)= (pi)/(260)

So then the possible anwer for this case would be:

D.) y= sin pi/260 theta

Since is the only option with satisfy the general equation of a wave.
