Solids or three-dimensional forms are shapes or figures that have three (or more) dimensions. The solid could be a Triangular prism or a pyramid.
What is a solid?Solids or three-dimensional forms are shapes or figures that have three (or more) dimensions. Solid Geometry is the study of the characteristics, volume, and surface area of three-dimensional forms.
Given a solid is cut by a plane that is perpendicular to its base, forming a two-dimensional cross-section in the shape of a triangle. Therefore, the solid could be a Triangular prism or a pyramid.

During her holiday, Hannah rents a bike. She pays a fixed cost of $8 and then a cost of $4.50 per day.
Hannah pays with a $50 note and receives $10.50 change.
Calculate for how many days Hannah rents the bike.
fixed cost= $8
cost= $4.50
payed= $50
recieved= $10.50
to find:how many days Hannah rented the bike.
solution:let the unknown be ( x )
[tex]x = 50 - (10.50 + 8)[/tex]
[tex]x = 50 - 18.50[/tex]
[tex]x = 13.50[/tex]
[tex]x = \frac{13.50}{4.50} [/tex]
[tex]x = 7[/tex]
hence, Hannah rented the bike for 7 days.

Answer:
See below ~
Step-by-step explanation:
Solving :
(a) Coordinates of P and Q
⇒ Equate the lines' equations
⇒ 2x² - 6x - 8 = 2x - 14
⇒ 2x² - 8x + 6 = 0
⇒ x² - 4x + 3 = 0
⇒ (x - 3)(x - 1) = 0
⇒ x = 3 and x = 1
Substitute each x-value in the any of the 2 equations :
⇒ y = 2(3) - 14
⇒ y = 6 - 14
⇒ y = -8
⇒ P = (3, -8)
⇒ y = 2(1) - 14
⇒ y = 2 - 14
⇒ y = -12
⇒ Q = (1, -12)
(b)
(i) 2x² - 6x - 8 = 0
⇒ x² - 3x - 4 = 0
⇒ (x - 4)(x + 1) = 0
⇒ x = 4 and x = -1
(ii) 2x² - 6x = -4
⇒ 2x² - 6x + 4 = 0
⇒ x² - 3x + 2 = 0
⇒ (x - 1)(x - 2) = 0
⇒ x = 1 and x = 2
(c) Line of symmetry
Finding the vertex :
⇒ Vertex = (h, k)
⇒ h = -b/2a
⇒ h = -(-6)/2(2)
⇒ h = 6/4
⇒ h = 1.5
⇒ The axis of symmetry's equation is : x = 1.5
(d)
⇒ As the mentioned function is a quadratic function, irrational values such as √2, √3, √6, etc. cannot be taken into consideration

Answer: hii
real :)
Step-by-step explanation:
"While it is not a real number — that is, it cannot be quantified on the number line — imaginary numbers are "real" in the sense that they exist and are used in math. Imaginary numbers, also called complex numbers, are used in real-life applications, such as electricity, as well as quadratic equations."

Which statement could be used to prove AB || CE?
Answer:
B
Step-by-step explanation:
Let's take a look at each statement.
A: ∠1 ≅ ∠8
Angle 1 is congruent to angle 8.
If lines are parallel then angle 1 and angle 8 would be same side (consecutive) exterior angles which are supplementary and not congruent.
Therefore this statement would prove that the lines are not parallel.
B: ∠1 ≅ ∠7
Angle 1 is congruent to angle 7.
If lines are parallel then angle 1 and angle 7 would be alternate exterior angles which are congruent.
This statement proves that the lines are parallel. We have angle 1 that is at line AB and angle 7 which is at line CD. It's important that one angle is at one line and the second angle at the other line, otherwise we cannot prove that the lines are parallel.
C: ∠6 ≅ ∠8
Angle 6 is congruent to angle 8.
Angles 6 and 8 are vertical angles and they are congruent.
This statement is correct but it doesn't tell us anything about the relationship of angles at the other line, therefore it proves nothing.
D: ∠1 and ∠2 are supplementary.
Angles 1 and 2 create a linear pair, therefore they are supplementary.
This statement is also correct but again it tells us nothing about the angles at the other line so it again proves nothing.
Use the graph of the function to find its domain and range. Write the domain and range in interval notation
Answers:
Domain: [tex](-\infty, 5)[/tex]
Range: [tex][-3, \infty)[/tex]
Both are in interval notation. There's a square bracket next to the -3, and everything else is a curved parenthesis.
===========================================================
Explanation:
The domain is the set of allowed x input values of a function. We have a hole at x = 5, so this value is not allowed in the domain. But we can use anything smaller than this. The domain as an inequality is [tex]x < 5[/tex] which is the same as writing [tex]-\infty < x < 5[/tex] and that directly translates to the interval notation of [tex](-\infty, 5)[/tex]
The curved parenthesis say "exclude this endpoint". The domain is anything between negative infinity to 5, excluding both endpoints.
----------------------
The range is the set of possible y outputs of a function.
The lowest the function goes is at y = -3. The arrow indicates it goes up forever, meaning that the range as an inequality is [tex]y \ge -3[/tex] which is the same as [tex]-3 \le y[/tex] and the same as [tex]-3 \le y < \infty[/tex]
Then that directly turns into the interval notation of [tex][-3, \infty)[/tex]
We have a square bracket at -3 to include this endpoint. We can't ever reach infinity, so we of course can't include this endpoint. Always use parenthesis for either infinity.

The nth term of the Sequence: 40, 33, 26, .... is 47 - 7n.
What is Arithmetic Progression?An arithmetic progression (AP) is a sequence where the differences between every two consecutive terms are the same.
Here, we know nth term of the Arithmetic Sequence is
Aₙ = A + (n - 1)D
where, A is first term and D is common difference
A = 40 and D = 33 - 40 = -7
Now, Aₙ = 40 + (n - 1) (-7)
Aₙ = 40 - 7n + 7
Aₙ = 47 - 7n
Thus, the nth term of the Sequence: 40, 33, 26, .... is 47 - 7n.
