Jessica has a circular birdbath in her backyard with a radius of 1.25 feet. She wants to place a decorated border around the cir

Alexxandr [17]

Answer:

The total cost is 28.26.

Step-by-step explanation:

The radius of the birdbath is 1.25 feet.

The cost per foot is 3.6 .

The formula for perimeter of circle is given by,

= 2πR , where R is the radius of circle.

Inserting the above value of radius in the equation above,

circumference = 2(π)(1.25) = 2(3.14)(1.25) = 7.85 $ft^{2}$

Thus the total cost is,

= (7.85)(3.6) = 28.26

Answer: .618033989 or 618033989/1000000000 or 61% (Not rounded)

Step-by-step explanation:

-1+ (the sign)5 = 1.236067977 and if you divide that by two you get .618033989 or 618033989/1000000000 or 61% (Not rounded)

At what angle does a diffraction grating produce a second-order maximum for light having a first-order maximum at 20.0 degrees?

hichkok12 [17]

Answer:

At 43.2°.

Step-by-step explanation:

To find the angle we need to use the following equation:

$d*sin(\theta) = m\lambda$

Where:

d: is the separation of the grating

m: is the order of the maximum

λ: is the wavelength

θ: is the angle

At the first-order maximum (m=1) at 20.0 degrees we have:

$\frac{\lambda}{d} = \frac{sin(\theta)}{m} = \frac{sin(20.0)}{1} = 0.342$

Now, to produce a second-order maximum (m=2) the angle must be:

$sin(\theta) = \frac{\lambda}{d}*m$

$\theta = arcsin(\frac{\lambda}{d}*m) = arcsin(0.342*2) = 43.2 ^{\circ}$

Therefore, the diffraction grating will produce a second-order maximum for the light at 43.2°.

I hope it helps you!
