What is the polar form of -9-9i√3?
Answer:
18(cos(4pi/3) + i sin(4pi/3))
Step-by-step explanation:
step 1: find the modulus (|z|=√(a^2 + b^2)
|z|=√((-9)^2+(-9√3)^2)= 81+243= 324 => √324=18
step 2: find the argument using theta =tan^-1 (y/x)
theta=tan^-1((-9√3)/-9) = √3
the tangent value of √3 in the third quadrant has the degree measure of 240 and the radian measure of 4pi/3.

The ratio of the measure of the sides of the triangle is 1/6: 1/3: 1/4 if the perimeter of the triangle is 13.5 inches. find the shortest side
Answer:
BRAINLIEST PLZZZZZ
Step-by-step explanation:
The shortest side of the triangle is 3 inches.
Given:
The ratio of the measure of the sides of the triangle is 1/6: 1/3: 1/4.
The perimeter = 13.5 inches.
Now, to find the shortest side.
Let the one side be = 1/6x
And the second side be = 1/3x
And the third side be = 1/4x
According to question:
1/6x + 1/3x + 1/4x = 13.5
x/6 = x/3 = x/4 = 13.5
Adding all the variables by taking common denominator we get:
⇒ 9x/12 = 13.5
Multiplying both sides by 12 we get:
⇒ 9x = 162
Dividing both sides by 9 we get:
⇒ x = 18
Thus, the sides of the triangle are:
1/6×18=3 inches.
1/3×18=6 inches.
1/4×18=9/2=4.5 inches.
Therefore, the shortest side of the triangle is 3 inches.

What is the domain of the following function?
What are the y values for the equation : y=0X-4 if x=-3
Note: Your equation expression seems a little unclear. So, I am assuming that your expression is
y = x - 4
The solution steps would anyway still clear your concept so that no matter what you can solve whatever the expression it is because the procedure remains the same.
Answer:
The value of y = -7 if x = -3
Step-by-step explanation:
Assuming the given the expression
[tex]y = x - 4[/tex]
Given that we have to find the value of y if x = -3.
so substituting x = -3 in the equation
[tex]y = x - 4[/tex]
[tex]y = (-3) - 4[/tex]
[tex]y = -3-4[/tex]
[tex]y = -7[/tex]
Therefore, the value of y = -7 if x = -3
The graph of the equation y = x- 4 is also attached below.

Answer:
SAS
Step-by-step explanation:
the lines in the middle of a segment mean that they are equal in length.
So OE = EB and AE = EC.
Now, since angle AEB and angle DEC are vertical angles, they are equal.
Therefore the triangles are equal by SAS
What is 365 divide by 3
Answer:
121.666667
Step-by-step explanation:
When 365 is divided by 3 the result or quotient is 121.66.
To calculate 365 divided by 3, we can perform long division:
Set up the division problem.
Determine how many times 3 can fit into the first digit of the dividend (3). The answer is 1.
Bring down the next digit (6) to the right of 3.
Determine how many times 3 can fit into the new number (36). The answer is 12.
Now, bring down the next digit (5) to the right of 12.
Determine how many times 3 can fit into the new number (53). The answer is 17.
Since there are no more digits to bring down, the division is complete.
The final result is: 365 ÷ 3
= 121.666...
Hence, 365 is divided by 3 to get 121.66.

What mistake did Brianna make? On Line 1, Brianna should have subtracted 3 instead of adding -3. On Line 1, Brianna violated the addition property of equality. On Line 3, Brianna should have divided by 0.1 instead of subtracting 0.1. On Line 3, Brianna violated the addition property of equality.
Question:
Brianna solved a two-step equation, but she made a mistake along the way.
[tex]0.1x + 3 = 1.7[/tex]
Line 1 : [tex](-3) + 0.1x + 3 = 1.7 + (-3)[/tex]
Line 2 : [tex]0.1x = -1.3[/tex]
Line 3 : [tex](-0.1) + 0.1x = -1.3 + (-0.1)[/tex]
Line 4: [tex]x = -1.4[/tex]
Answer:
On Line 3, Brianna should have divided by 0.1 instead of subtracting 0.1.
Step-by-step explanation:
Required
Where did she make a mistake?
To do this, we simply analyse her workings one step at a time
Equation: [tex]0.1x + 3 = 1.7[/tex]
Line 1 : [tex](-3) + 0.1x + 3 = 1.7 + (-3)[/tex]
This is correct because she subtracted 0.3 from both sides
Line 2 : [tex]0.1x = -1.3[/tex]
This is also correct because she performed the arithmetic correctly
Line 3 : [tex](-0.1) + 0.1x = -1.3 + (-0.1)[/tex]
This is incorrect.
Division by 0.1 is expected not subtraction

Step-by-step explanation:
The amount of water (in liters) in tank 1 after t minutes is 30t + 25. The amount of water (in liters) in tank 2 after t minutes is −20t + 1000. Find the time when the amount of water will be equal.
Answer:
The water amount will be equal at 19.5 minutes
Step-by-step explanation:
Here, we want to find the value of t when the water level in both tanks will be equal
We simply proceed to equate both ;
That will be;
30t + 25 = -20t + 1000
30t + 20t = 1000-25
50t = 975
t = 975/50
t = 19.5 minutes

Write an equation for each representation of a quadratic function given below.
Let, us assume that quadratic equation is :
[tex]y = ax^2 + bx + c[/tex]
Now, putting x = 0 and y = -4 :
[tex]c = -4[/tex]
Also, putting x = 1 and y = -3 :
[tex]ax^2 + bx + c =y\\\\a + b - 4 = -3 \\\\a + b = 1[/tex] ....2)
Also, putting x = 2 and y = 0 :
[tex]ax^2 + bx + c =y\\\\4a + 2b + c = 0\\\\4a + 2b = 4\\\\2a - b = 2[/tex]....3)
Solving equation 2 and 3, we get :
a = 1 and b = 0
Therefore, the quadratic equation is given by [tex]y = x^2- 4[/tex] .
