Answer:
Step-by-step explanation:
(-5 - 4i)(-5 + 4i)
25 - 20i + 20i - 16 i^2
25 + 16
41 + 0i
Given complex number is (-5 - 4i).
Therefore, conjugate of this number will be (-5 + 4i)
[Conjugate of a complex number (a + bi) is (a - bi)]
Multiplication of the number and the conjugate of this number will be,
(-5 - 4i)(-5 + 4i) = (-5)² - (4i)²
= 25 - (16i²)
= 25 - (16)(-1) [Since, i² = (-1)]
= 25 + 16
= 41
It can be written in the form a complex form → (41 + 0.i)
Therefore, a = 41 and b = 0.

Answer:
Area = 10
Step-by-step explanation:
Here is how to solve:
(x1y2+x2y3+x3y1-y1x2-y2x3-y3x1) / 2
In your case
A(2,2) is x1=2, y1=2
B(6,2) is x2=6, y2=2
C(6,7) is x3=6, y3=7
So
((2x2)+(6x7)+(6x2)-(2x6)-(2x6)-(7x2)) divided by 2 = 10
Area = 10

Step-by-step explanation:
28/16 = 1.75
1.75 is the constant of proportionality
63/1.75 = 36
therefore, 2x+8 should be equal to 36
2x+8 = 36 >> subtract 8 from both sides
2x = 28 >> divide both side by 2 to get x alone
x = 14

Is 1 + 4(3x - 10) - 12x equivalent to -9? EXPLAIN and show your work.
Answer:
Since you have to distribute the 4 to both terms in parentheses, the equation is simplified like this:
1 + 12x - 40 -12x
= 1 - 40
= -39
Step-by-step explanation:
Answer: No
Step-by-step explanation:
1 + 4(3x - 10) - 12x = 9
simplifies to
1+12x - 40 -12x =9
combine like terms to get
-39 = 9
This is not possible so the answer is no.
the insructions for a model car show a scale of 1 inch to 48 inches. How long is the actual car if the drawing is 4 inches
Answer:
192
Step-by-step explanation:
Answer:
192
Step-by-step explanation:
The ratio of inches to inches is 1:48
To get 4:x
You have to multiply, 4/1 = 4, 4 by 48.
4*1 = 4
4*48 = 192
4:192 = 1:48 * 4

Prove that the triangle with vertices A(0,1), B(3,3), and C(3,-1) is an isosceles triangle. Select the two sides that are congruent.
Answer:
AB and AC are congruent
Step-by-step explanation:
To show that the triangle is isosceles, we need to show that two of the sides of the triangle are equal.
Get AB
Using the formula for calculating the distance between two points
AB = √(x2-x1)²+(y2-y1)²
A(0,1), B(3,3)
AB = √(3-0)²+(3-1)²
AB = √3²+2²
AB = √9+4
AB = √13
Get BC
B(3,3), and C(3,-1)
BC = √(3-3)²+(-1-3)²
BC = √0²+-4²
BC= √0+16
BC = √16
BC = 4
Get AC
A(0,1), and C(3,-1)
AC = √(3-0)²+(-1-1)²
AC = √3²+(-2)²
AC = √9+4
AC= √13
Since AB = AC, this shows that the triangle ABC is an isosceles triangle.
The two sides that are congruent are AB and AC
