Let z = 19 + i and w = 4 + 10i.
What is the first step in determining zw?
Replace i2 with –1.
Multiply z by the conjugate of w.
Apply the distributive property or FOIL.
Combine the corresponding real and imaginary parts.
EDGE
In the first step apply the distributive property or FOIL to find zw. Option C is correct.
Given that,
Let z = 19 + i and w = 4 + 10i.
The first step is to be determined.
The number that constitute of real and imaginary numbers are called a complex numbers. Complex number is represents as z = a + ib, where a = real number and bi = imaginary number
z = 19 + i and w = 4 + 10i
in order to find the product of complex numbers z and w following are the steps,
z.w = ( 19 + i )( 4 + 10i )
Step ⇒ 1
Applying distributive law,
z.w = 19 * ( 4 + 10i ) + i * ( 4 + 10i )
Step ⇒ 2
opening the parenthesis,
z.w = 19 * 4 + 19*10i + i * 4 + i * 10i
similarly, further steps are
z.w = 76 + 190i +4i + 10i²
since i² = -1
z.w = 76 + 194i - 10
z.w = 66 + 194i
Thus, in the first step apply the distributive property or FOIL to find zw. Option C is correct.

are there instances that rational algebraic equation can be transformed into quadratic equation
Answer:
yeah
Step-by-step explanation:
hmm
Answer:
yes you can
Step-by-step explanation:
for example you have a second order algebraic equation, which have the general form ax^2 + bx + c = 0, for any constants a, b, and c, you can use the quadratic equation to find the values of x. However, sometimes it is easier to simply factor the expression into (fx+g)(hx+i) = 0, for any constants f, g, h, and i, and then solve the two resulting equations fx+g = 0 and hx+i=0 for the values of x.

laura spent 2/5 of her money now she has $18 left how much money did she have origanily
Answer:
Money Laura had originally = $30
Step-by-step explanation:
Let the money Laura had = x
Money spent = 2/5 of x = [tex]\frac{2}{5}x[/tex]
Remaining money = $ 18
[tex]x - \frac{2}{5}x = 18\\\\\frac{x*5}{1*5}-\frac{2}{5}x = 18\\\\\frac{5x}{5} - \frac{2x}{5} = 18\\\\\frac{3x}{5}=18\\\\ 3x = 18*5\\\\3x = 90\\\\x = \frac{90}{3}\\\\x = 30[/tex]
Money Laura had originally = $30

1. un numar se mareste cu 4 iar rezultatul se mareste de 4 ori. noul rezultat micsorat cu 4 se imparte la 4 si se obtine 4.aflati numarul
Răspuns:
1
Explicație pas cu pas:
Fie numărul = x
x + 4 = e - - (1)
e * 4 = f - - - (2)
Ecuația 2 - 4 împărțită la 4 = 4
(f - 4) / 4 = 4
Crucea se înmulțește
f - 4 = 16
f = 16 + 4
f = 20
Rezultatul 1 împărțit la 4 este egal cu 4
Prin urmare,
e = f / 4
f = 20
e = 20/4
e = 5
De la (1)
x + 4 = e
x + 4 = 5
x = 5 - 4
x = 1

If on a scale drawing 75 feet are represented by 45 inches, then a scale of 1/5 represents how many feet
Answer:
1/3 feet
Step-by-step explanation:
We are given that
On a scale drawing
45 inches represented =75 feet
We have to find a scale of 1/5 inch how many feet represents.
To find the value in feet represented by a scale of 1/5 inch we will use unitary method.
Using unitary method
45 inches represents =75 feet
1 inch represents = feet
1/5 inch represents = feet
1/5 inch represents= feet
Hence, a scale of 1/5 inch represents 1/3 feet
