What are sets and subsets?A set is a collection of well-defined objects.
A subset contains all the elements or a few elements of the given set.
The improper subset is when it contains all the elements of the given set and the proper subset is when it doesn't contain all the elements of the given set
Complex numbers (a + ib)
Real numbers Imaginary numbers.
(a + i0) (0 + ib)

Find the slope of the line graphed.
My Answer:
Answer:
The slope is (2/5) or 0.40
Step-by-step explanation:
Slope is the rise of the line (y axis) over run (x axis). Take any two points. I picked (0,-2) and (5,0). The run is the change in x, which is (5 - 1) or 5. The rise for this change in x is (0 -(-2)) = 2. Rise/Run = 2/5 or 0.40.

To isolate the variable in 1/4x multiply by _ or divide by _
Answer: To isolate the variable in ¹/₄ x multiply by 4 or divide by 1
Step-by-step explanation:
Let ¹/₄ x = a
multiply by 4: 4 (¹/₄) x = 4 a
1 x = 4 a
divide by 1: ¹/₁ x = ⁴/₁ a
x = 4a [x is now isolated]
To isolate the variable in 1/4x multiply by 4 or divide by 1/4
How to isolate the variable in 1/4xFrom the question, we have the following parameters that can be used in our computation:
Expression = 1/4x
To isolate the variable in 1/4x, we multiply by 4
So, we have
Expression = 1/4x * 4
Expression = x
OR
To isolate the variable in 1/4x, we divide by 1/4
Expression = 1/4x / 1/4
Expression = x

Answer:
4.) Cost of cordless phone = $55
cost of each additional handset = $25
Therefore, the overall cost of the cordless phone, including the 3 extra handsets is:
$55 + 3($25) = $55 + $75 = $130
5.) Given the function, f(d ) = .20d + 14, where:
f(d) = global temperature (in Celsius)
d = number of decades
To evaluate the value of f (d ) at f(10), you'll have to substitute the value of d = 10 as input into the function:
f(10) = .20(10) + 14
f(10) = 2 + 14
f(10) = 16
6.) Value of f(10):
In 10 decades, the predicted global temperature will be 16° Celsius.
7.) The correct answer is B. The global temperature f(d) depends on the number of decades, d.
Explanation: the independent variable is d → it is the input of the function. The output primarily depends on the given value of input.
8.) Given the function, f(t ) = 0.2t
where t = represents number of days elapsed since the planting of the seed.
Evaluate f(40):
f(40) = 0.2(40)
f(40) = 8
Context of f(40): The value of the function, f(40) = 8 represents the 8 centimeter height of the habanero plant after 40 days of planting its seeds.

D.) 256
Step-by-step explanation:
The first week she made 4 hats, the next week she made 4 times as much which is 16( 4x4=16). The third week she made 64 (16x4=64). The fourth week she made 256 (64x4)
Answer:
256 hats.
Step-by-step explanation:
You can see that every week, the number of hats knitted increases times 4;
1st week: 4 hats knitted.
1st week: 4 hats knitted in total.
2nd week: 4 times as many hats knitted the first week; (4 x 4 = 16).
2nd week: 16 hats knitted in total.
3rd week: 4 times as many hats knitted the second week; (16 x 4 = 64).
3rd week: 64 hats knitted in total.
4th week: 4 times as many hats knitted the third week; (64 x 4 = 256).
4th week: 256 hats knitted in total.

Select the correct line. Which line is perpendicular to AB
Answer:
line 1
Step-by-step explanation:
perpendicular is the opposite so therefore line 1 is the answer
From the given figure, line AB perpendicular to line 1.
We need to check which line is perpendicular to AB.
What are perpendicular lines?In elementary geometry, two geometric objects are perpendicular if they intersect at a right angle. The condition of perpendicularity may be represented graphically using the perpendicular symbol, ⟂. It can be defined between two lines, between a line and a plane, and between two planes.
From the given figure we can see that line AB perpendicular to line 1.
The line AB perpendicular to line 1, intersect each other and made an angles 90°.
Therefore, from the given figure, line AB perpendicular to line 1.

A garden is in the shape of a trapezium whose parallel sides are 40m and 22m and the perpendicular distance between them is 12m. Find the area of the garden
Answer:
A = 372 m²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₁ the parallel bases
Here h = 12, b₁ = 40 and b₂ = 22 , then
A = [tex]\frac{1}{2}[/tex] × 12 × (40 + 22) = 6 × 62 = 372 m²
Determine if (0,-5) is a
solution to the equation
y = -5x
Plug (0,-5) into the equation -
-5 = -5(0)
-5 times 0 is 0
-5 = 0
(0,-5) is NOT a solution to the equation.
Good luck!
Answer:
No, it is not the solution to the equation.
Step-by-step explanation:
(0, -5)
y = -5x
So we have to plug in the values for x and y. 0 is our x value and -5 is our y value.
-5 = -5(0)
-5 = 0
Therefore, (0, -5) is not a solution to the equation

Step-by-step explanation:
(1 - cos²A)(1 + tan²A) = tan²A
1 + tan²A - cos²A - cos²A · tan²A = tan²A
1 + tan²A(1 - cos²A) - cos²A = tan²A
1 - cos²A + tan²A(sin²A) = tan²A
sin²A + tan²A(sin²A) = tan²A
sin²A (1 + tan²A) = tan²A
sin²A (sec²A) = tan²A
sin²A (1/cos²A) = tan²A
