Tìm căn bậc hai của số phức z=1+i√3
Anni [7]

Write <em>z</em> in polar form:

<em>z</em> = 1 + √3 <em>i</em> = 2 exp(<em>i</em> <em>π</em>/3)

Taking the square root gives two possible complex numbers,

√<em>z</em> = √2 exp(<em>i</em> (<em>π</em>/3 + 2<em>kπ</em>)/2)

with <em>k</em> = 0 and <em>k</em> = 1, so that

√<em>z</em> = √2 exp(<em>i</em> <em>π</em>/6) = √(3/2) + √(1/2) <em>i</em>

and

√<em>z</em> = √2 exp(<em>i</em> 7<em>π</em>/6) = -√(3/2) - √(1/2) <em>i</em>

En un día de febrero, una ciudad de Estados Unidos registró una temperatura mínima de 9° bajo cero y una temperatura máxima de 1
____ [38]

Answer:

La cantidad de grados del intervalo de temperaturas registradas en el día de febrero mencionado es de:

  • <u>5</u>

Step-by-step explanation:

En estadística, cuando se utilizan intervalos como valores para identificar datos cuantitativos, como en este caso temperaturas registradas, deben tomarse todos los valores, en este caso enteros, desde el límite inferior (temperatura mínima) hasta el límite superior (temperatura máxima), por lo cual no se puede restar el valor máximo al valor mínimo, sino que debes identificar todos los valores y después contarlos. En el caso del ejercicio dado, los grados en el intervalo mencionado son:

  1. 9°C
  2. 10°C
  3. 11°C
  4. 12°C
  5. 13°C

Como puedes ver, los grados en el intervalo de temperaturas registradas serían 5.

OKIE I NEED HELP WITH MY MATH CUZ THE INTERNET IS S T U P I D
Rom4ik [11]
When reflecting a point across the x-axis, you multiply the y coordinate by -1 (you flip the sign), so (-8,-3) would turn into (-8,3).

When reflecting a point across the y-axis, you multiply the x coordinate by -1 (flip the sign), so (-8, -3) becomes (8, -3)

Without multiplying, tell which is greater: 4/5 x 45 or 2/3 x 45. Explain.
Aloiza [94]

Answer: It is 4/5 x 45

Step-by-step explanation: Hope i helped please mark brainliest!

I know there is suppose to be no multiplying but if you mulitply in your head 4/5 x 45 is 36 and 2/3 x 45 is 30

therefore, 4/5 x 45 is greater!

also, if not multiplying 0.8(5/4) is greater than 0.667(2/3). Therefore, 4/5 is greater than 2/3.
