<span>f(x)=5(x+4)^3/2,    let y = f(x).
</span>
<span>y =5(x+4)^3/2.  The y intercept is value of y when x = 0

y intercept =  </span><span>5(0+4)^3/2 =  5*  4^3.2 =  5*6 = 30.      Use your calculator.
 
y intercept  = 30

kati45 [8]
First, 
149,500 * .10 = 14,950
149,500 - 14,950 = 134,550

then,
134,550 * .05 = 6727.50
134,550 - 6727 = 127,822.55 
127,822.50 * .04 = 5112.90

trade discount = 14950 + 6727.50 + 5112.90 
26790.40

hope this help

Explain the geometric efect of z if you multiply z by ????????, where<br> ???????? = 1 + i
BartSMP [9]

Answer:

You will obtain a complex number rotated by an angle of 45 degrees (counterclockwise) with a modulus scaled by √2

Step-by-step explanation:

In order to see the effect of multiplying z by 1 + i, you can use the representation of complex numbers in the <em>Polar Form</em>. This representation gives you the angle formed by the complex number and the real axis and the distance from the origin to the point.

Let z=a+ib represent a complex number.<em> The Polar</em> Form is:

z = |z| (Cosα + iSinα)

Where |z| is the modulus of the complex number and α is the angle formed with the real axis.

|z| = √a²+b²

α= arctan (b/a)

The multiplication in<em> Polar Form</em> is:

Let Z0 and Z1 represent two complex numbers

Z0= |Z0| (Cosα + iSinα)

z1= |z1|(Cosβ + iSinβ)

The multiplication is:

Z0.Z1 =  |Z0||Z1| [Cos(α+β) + i Sin(α+β)]

Notice that when you multiply complex numbers, you are adding angles and multiplying modulus. The addition of angles can be seen as a rotation of the complex number on the plane and the multiplication of modulus can be seen as changing the modulus of the complex number.

The given number 1+i in the Polar Form is:

z = |z| (Cosα + i Sinα)

|z| = √1²+1² = √2

α = arctan(1/1) = 45°

Therefore, you will obtain a complex number rotated by an angle of 45 degrees with a modulus scaled by √2
