Let ? be x
Now ,
Now by means and extremes ,
=> 6x = 13 × 11
=> x = 143 ÷ 6
=> x = 23.833 ≈ 23
So option C is your answer
Step-by-step explanation:
z

z^3=2^3(\cos(6^3)^\circ+i\sin(6^3)^\circ)z

\implies z=8^{1/3}\left(\cos\left(\dfrac{216+360k}3\right)^\circ+i\sin\left(\dfrac{216+360k}3\right)^\circ\right)⟹z=8
1/3
(cos(

∘
+isin(

)
where k=0,1,2k=0,1,2 . So the third roots are
\begin{gathered}z=\begin{cases}2(\cos72^\circ+i\sin72^\circ)\\2(\cos192^\circ+i\sin192^\circ)\\2(\cos312^\circ+i\sin312^\circ)\end{cases}\end{gathered}

an algebraic expression for three fourths the square of b
=> Algebraic expression is the expression that shows both integers,
variables, symbols and operations like addition, subtraction, division, and
multiplication.
=> three fourth is a fraction which is equals to 3/4
=> square of b is an exponent which is equals to b<span>2
</span>=> thus, the algebraic expression of three fourths the square of b is
equals to:
=> ¾ x b2 or 3b2 / 4</span>
Answer:
There is a 1/8 chance.
If there are 4 cards in the deck, and one three card, it makes it a 1/4 chance of picking the card the first time.
The probability stays the second time you pull out a card.
So, you would do the equation 1/4 * 1/4, which is 1/8. That is the answer.
Answer:
Literally divide by 7 and you get -5
