Find the are of each figure

Mathematics
1 answer:
Umnica [9.8K]2 years ago
8 0

Answer:

I think the figure of N and E of 48in is 2304. The figure of I and E and N and A of 32in is 1024. The figure of L and I and L and A is 144.

Step-by-step explanation:

To find the area, you have to multiply of each side in each figure. For example, Figure A and B and C and D of 16in is 16 × 16 which is 256.

A = Area

a = Side

A = 2304, A = a^2 = 48^2 = 2304.

A = 1024, A = a^2 = 32^2 = 1024.

A = 144, A = a^2 = 12^2 = 144.

I hope this answers your question!

What is the inverse and restricted domain of the equation 8x^2-3
kari74 [83]

Answer:  \bold{y=\pm \dfrac{\sqrt{2(x+3)}}{4},\qquad x\neq -3}

<u>Step-by-step explanation:</u>

y = 8x² - 3            (Restriction: none -  x is All Real Numbers)

The inverse is when you swap the x's and y's and then solve for y

x = 8y² - 3            <em>swapped the x and y</em>

x + 3 = 8y²           <em>added 3 to both sides</em>

\dfrac{x+3}{8}=y^2           <em>divided both sides by 8</em>

\sqrt{\dfrac{x+3}{8}}=\sqrt{y^2}           <em>square rooted both sides</em>

\pm \sqrt{\dfrac{x+3}{8}}=y           <em>simplified</em>

\pm \sqrt{\dfrac{x+3}{8}\bigg(\dfrac{2}{2}\bigg)}=y           rationalized the denominator

\pm \sqrt{\dfrac{2(x+3)}{16}}=y           <em>simplified</em>

\pm \dfrac{\sqrt{2(x+3)}}{4}=y           <em>simplified</em>

<u>Restriction:</u>

The radical <em>(inside the square root sign)</em> cannot be negative

→  2(x + 3) ≥ 0

      x + 3 ≥ 0         <em>divided both sides by 2</em>

      x       ≥ -3         <em>subtracted 3 from both sides</em>

15 points. Would the rules for interference work the same for light waves as they do for sound waves? Explain why or why not.
Vilka [71]

Answer:

Yes, because when waves are at the same place at the same time, the amplitudes of the waves simply add together and this is really all we need to know!

Step-by-step explanation:

The sum of two waves can be less than either wave, alone, and can even be zero. This is called destructive interference.

If we place the waves side-by-side, point them in the same direction and play the same frequency, we will have  constructive interference.
