Answer:
When a complex number z is written in its polar form,z = r(cos theta + i sin theta), the nonnegative number r is called the magnitude, or modulus, of z.
In mathematics, magnitude is the size of a mathematical object, a property by which the object can be compared as larger as or smaller than other objects of the same kind. More formally, an object's magnitude is an ordering (or ranking) of the class of objects to which it belongs.

Solve for L:
P=2L+2W
Answer:
[tex]L=\frac{1}{2}P-W[/tex]
Step-by-step explanation:
Let's solve for L.
[tex]P=2L+2W[/tex]
Step 1: Flip the equation.
[tex]2L+2W=P[/tex]
Step 2: Add [tex]-2W[/tex] to both sides.
[tex]2L+2W+-2W=P+-2W[/tex]
[tex]2L=P-2W[/tex]
Step 3: Divide both sides by [tex]2[/tex].
[tex]\frac{2L}{2}=\frac{P-2W}{2}[/tex]
[tex]L=\frac{1}{2}P-W[/tex]
Answer:
[tex]L=\frac{1}{2}P-W[/tex]

Find f(g(2)).
f(x) = 2x + 1
g(x) = 5x
10
12
21
-14
Answer:
21
Step-by-step explanation:
First, we have to find g(2)
Plug in 2 in the g(x) equation
g(2) = 5(2) = 10
Now, we have f(10)
Pug in 10 in the f(x) equation
f(10) = 2(10) + 1
f(10) = 20 + 1 = 21

Thanksgiving Meal Challenge
Considering the final price of the meal, would you rather have a $25 gift
card to apply toward to total price or a 35% off coupon? Show your work
and explain.
If the price of the meal is less than $71, then the $25 gift card would be better than the 35% off coupon.
Let y represent the price of the meal.
For a $25 gift card to be applied, the final price is:
Final price = y - 25
For a 35% off coupon, the final price is:
Final price = y - 0.35y = 0.65y
y - 25 < 0.65y
0.35y < 25
y < 71.42
If the price of the meal is less than $71, then the $25 gift card would be better than the 35% off coupon.

Liam had $250. Then, he and his classmates bought a present for their teacher, evenly splitting the $p cost
among the 24 of them.
How much money does Liam have left?
Write your answer as an expression.
$=
Answer:
250 - [tex]\frac{p}{24}[/tex]
Step-by-step explanation:
Since we have given that
Amount that Liam has = $250
Amount that he and his classmates spent on present for their teacher =$p
Number of students in which $p will split = 24
According to question,
Amount that left to Liam is given by
250 - [tex]\frac{p}{24}[/tex]
Hence, the required expression will be

Answer:
a. Zachary is correct
b. (-1)(-3) = 3 (Scott & Tina are wrong); (5)(-2) = -10 (Aaron is wrong); (1)(3) = 3
Step-by-step explanation:
a. An even number of minus signs in a product will mean the product is positive; an odd number will mean the product is negative. Zachary's observation is consistent with this rule. Zachary is correct.
We can show the others are incorrect using a counter-example.
(-1)(-3) = 3 . . . . shows Scott, Aaron, and Tina are incorrect
Tina's rule is not consistent with the commutative property of multiplication.
Aaron's rule applies to addition, but not to multiplication.
__
b. The example used above is one example. Here are two more.
(-1)(-3) = 3 . . . . . shows Zachary correct; Scott, Aaron, Tina incorrect
(5)(-2) = -10 . . . . Aaron's own example shows him incorrect
(1)(3) = 3 . . . . . . agrees with all students' observations

Starting at sea level, a submarine descended at a constant rate to a depth of −3/4 mile relative to sea level in 5/8 minutes.
The submarine continues to descend at the same rate. What is the submarine's depth relative to sea level after the first minute?
Answer:
Step-by-step explanation:
Let r be the rate of descent in miles per minute
-3/4 miles / 5/8 minutes
-3/4 • 8/5 = -24 / 20 = -1.2 mi/min
so in one minute
-1.2 mi/min (1 min) = -1.2 miles

x = 10
Step-by-step explanation:
RO and OQ are congruent
Since RO = 50, and RQ = 12x - 20,
OQ = 12x - 20 - 50 = RO
50 = 12x - 70
120 = 12x

The sum of a number nd its opposite will always add up to
absolute value?
Answer:
On the number line, a number and its opposite are, predictably, opposite each other. In other words, they are the same distance from zero, but on opposite sides of the number line. The opposite of zero is defined to be simply zero. The sum of a number and its opposite is always zero, as shown in the following example.
Five kittens are sharing 6 cups of milk equally. How much milk does each kitten get?
Answer:
1 1/5
Step-by-step explanation:
We know that there is 5 kittens that have to eat six bowls of milk
Each cat would get 1 whole bowl of milk. All the kittens have to share 1/5 of the sixth bowl of milk.
Five kittens are sharing 6 cups of milk equally so 1 1/5 cup of milk is given to each kitten.
What is meant by Mathematical expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows: Expression: (Math Operator, Number/Variable, Math Operator)
Expressions in writing are made using mathematical operators such addition, subtraction, multiplication, and division.. For instance, the mathematical equation for "4 added to 2" will be 2+4.
Arithmetic operations are the most fundamental type of mathematical expression. Any combination of numbers and a mathematical operation, such as multiplication, addition, subtraction, or division, are considered arithmetic operations. For instance, the arithmetic operation 9 + 14/2 - 6*(5 + 3) results in -32.
Given,
6 cup of milk so there are 5 kitten
To give 6 cup of milk to 5 kitten is=6/5
= 6/5
=1 1/5
Therefore Five kittens are sharing 6 cups of milk equally so 1 1/5 cup of milk is given to each kitten.

Use the graph to determine the
solution (solutions) of the equation
f(x) = 0.
Please help, with explanation
Answer:
-3, 1
Step-by-step explanation:
The vertical scale of the graph is f(x). So, f(x) = 0 is the x-axis. Where the graph crosses the x-axis, the value of f(x) is 0.
The x-axis is labeled on alternate lines. Those labels are sufficient to tell you that each grid line represents one unit. The curve intersects the x-axis 3 units to the left of the vertical axis, at x = -3, at 1 unit to the right of the vertical axis, at x = 1.
The values of x where f(x) = 0 are -3 and 1.
