What complex number is represented by the polar coordinates (4, -pi/4)

nexus9112 [7]

Answer:

$\displaystyle \large{z=2\sqrt{2} -2 \sqrt{2}i}$

Step-by-step explanation:

A complex number is defined as z = a + bi. Since the complex number also represents right triangle whenever forms a vector at (a,b). Hence, a = rcosθ and b = rsinθ where r is radius (sometimes is written as <em>|z|).</em>

Substitute a = rcosθ and b = rsinθ in which the equation be z = rcosθ + irsinθ.

Factor r-term and we finally have z = r(cosθ + isinθ). How fortunately, the polar coordinate is defined as (r, θ) coordinate and therefore we can say that r = 4 and θ = -π/4. Substitute the values in the equation.

$\displaystyle \large{z=4[\cos (-\frac{\pi}{4}) + i\sin (-\frac{\pi}{4})]}$

Evaluate the values. Keep in mind that both cos(-π/4) is cos(-45°) which is √2/2 and sin(-π/4) is sin(-45°) which is -√2/2 as accorded to unit circle.

$\displaystyle \large{z=4\left(\frac{\sqrt{2}}{2} - \frac{\sqrt{2}}{2}i \right)}\\\\\displaystyle \large{z=2\sqrt{2} -2 \sqrt{2}i}$

Hence, the complex number that has polar coordinate of (4,-45°) is $\displaystyle \large{z=2\sqrt{2} -2 \sqrt{2}i}$

Step-by-step explanation:

$\tt{ 1. \: \: 4 \frac{1}{9} + 1 \frac{1}{2}}$

⇢ $\tt{ \frac{37}{9} + \frac{3}{2} }$

⇢ $\tt{ \frac{37 \times 2 + 3 \times 9}{18} }$

⇢ $\tt{ \frac{74 + 27}{18} }$

⇢ $\tt{ \frac{101}{18}}$

⇢ $\boxed{ \tt{5 \frac{11}{18}} }$

---------------------------------------------------------

$\tt{ \: 2. \: \: 4 \frac{1}{2} \div \frac{3}{5}}$

⇢ $\tt{ \frac{9}{2} \times \frac{5}{3}}$

⇢ $\tt{ \frac{9 \times 5}{2 \times 3}}$

⇢ $\tt{ \frac{45}{6}}$

⇢ $\boxed{ \tt{7 \frac{3}{6}} }$

Suppose f(x) = x². Find the graph of<br> f(x+3).<br> ???

alexdok [17]

Answer: x^2+3

Step-by-step explanation:

If regular f(x) is equal to x^2, then if you just add 3 to the original, you add 3 to the same x^2. The three becomes a shift upwards on the graph. You put your vertex point up 3 on the vertical line then make your parabola
