17. Observe the figure and name the following
a) Vertices of the polygon
b) Two pairs of adjacent sides
c) Two diagonals
d) Sides of the polygon
By using the image of the polygon and the definition for the parts, we can see that:
a) A, B, C, D, and E.b) DC and CB, AE and ED.c) AD, BEd) AB, BC, CD, DE, and EA.How to identify the parts of the figure?a) The vertices are the points where two sides connect, in this case, each letter represents a different vertex, so the vertices of the polygon are A, B, C, D, and E.
b) Adjacent sides are any pair of sides that are connected by a vertex.
For example, DC and CB are connected through vertex C, so these are adjacent sides.
Another pair can be BA and AE.
c) Diagonals are the segments between two non-consecutive vertices.
For example, E and D are consecutive vertices (because there are next to each other). And A and D are non-consecutive vertices.
Then AD is a diagonal. Another example can be EB.
d) The sides of the polygon are the segments between consecutive vertices, in this case, the sides are:
AB, BC, CD, DE, EA.

Answer:
Solutions: (0,11) ; (1,15) ; (2, 19)
Step-by-step explanation:
y - 3 = 4(x +2)
y - 3 = 4x + 8
y = 4x + 8 + 3
y = 4x + 11
When x = 0 , y = 11 (0,11)
When x = 1 ; y = 4 +11 = 15 (1, 15)

Which interval notation represents the set of all numbers less than or equal to -6 or greater than or equal to -2
Answer: 1≤x<12
Step-by-step explanation:
The values that are greater than or equal 1 but less than 12 are values ranging from 1 to 11 i.e {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11}. Note that 1 is included because the number is greater than or equal to 1 (1 included) and less than 12(12 not included).
x≥1 and x< 12
if x≥1, it means 1≤x
combining both inequality
1≤x and x<12

Exercise 3.5. For each of the following functions determine the inverse image of T = {x ∈ R : 0 ≤ [x^2 − 25}.
1. f : R → R defined by f(x) = 3x^3
2. g : R+ → R defined by g(x) = ln(x).
3. h : R → R defined by h(x) = x − 9
a. The inverse image of f(x) is f⁻¹(x) = ∛(x/3)
b. The inverse image of g(x) is [tex]g^{-1}(x) = e^{x}[/tex]
c. The inverse image of h(x) is h⁻¹(x) = x + 9
The domain of TSince T = {x ∈ R : 0 ≤ [x^2 − 25} ⇒ x² - 25 ≥ 0
⇒ x² ≥ 25
⇒ x ≥ ±5
⇒ -5 ≤ x ≤ 5.
Inverse image of f(x)
The inverse image of f(x) is f⁻¹(x) = ∛(x/3)
f : R → R defined by f(x) = 3x³
Let f(x) = y.
So, y = 3x³
Dividing through by 3, we have
y/3 = x³
Taking cube root of both sides, we have
x = ∛(y/3)
Replacing y with x we have
y = ∛(x/3)
Replacing y with f⁻¹(x), we have
So, the inverse image of f(x) is f⁻¹(x) = ∛(x/3)
Inverse image of g(x)
The inverse image of g(x) is [tex]g^{-1}(x) = e^{x}[/tex]
g : R+ → R defined by g(x) = ln(x).
Let g(x) = y
y = ln(x)
Taking exponents of both sides, we have
[tex]e^{y} = e^{lnx} \\e^{y} = x[/tex]
Replacing x with y, we have
[tex]y = e^{x}[/tex]
Replacing y with g⁻¹(x), we have
So, the inverse image of g(x) is [tex]g^{-1}(x) = e^{x}[/tex]
Inverse image of h(x)The inverse image of h(x) is h⁻¹(x) = x + 9
h : R → R defined by h(x) = x − 9
Let y = h(x)
y = x - 9
Adding 9 to both sides, we have
y + 9 = x
Replacing x with y, we have
x + 9 = y
Replacing y with h⁻¹(x), we have
So, the inverse image of h(x) is h⁻¹(x) = x + 9

theatre members, and 30 members of science club. The researchers want to get 20
respondents out of these organizations. Identify the samples to be taken in each
organization.
⚘Refer to the attachment for solution!!~
The sample to be taken in each organization such as 2.6 in the taekwondo club, 5.3 in the math club, 8 in the drama club, and 4 in the science club.
Total members of taekwondo club = 20
Total members of math club = 40
Total members of drama club = 60
Total members of science club = 30
The researchers want to get 20 respondents out of these organizations.
What is the stratified sampling method?The stratified sampling method is the process of dividing members of data into homogenous subgroups before sampling.
The total number of members = 150
For taekwondo club
= Total members of taekwondo club /total number of members × 20
= 20/150 × 20
= 2.6
For math club
= Total members of math club/total number of members×20
= 40/150 × 20
= 5.3
For drama club
= Total members of drama club/total number of members × 20
= 60/150 × 20
= 8
For science club
= Total members of the science club/total number of members × 20
= 30/150 × 20
= 4

In ΔUVW, the measure of ∠W=90°, VU = 41, UW = 9, and WV = 40. What is the value of the cosine of ∠V to the nearest hundredth?
Answer:
∠V = 12.68°
Step-by-step explanation:
In this question, we are tasked with calculating the value of the sine of ∠V to the nearest hundredth
Kindly note that since one of the angles in the triangle equals 90°, then we are dealing with a right-angled triangle.
PLEASE VIEW ATTACHMENT TO SEE THE DIAGRAM OF THE SHAPE
Mathematically, to calculate the sine of an angle in a triangle, the ratio to use is
Sine of an angle = length of side facing angle/length of hypotenuse = opposite/Hypotenuse
From the diagram, we can see that the length of the opposite is 9 while the length of the hypotenuse is 41
Sine V = 9/41
V = arcsin (9/41)
V = arcsin (0.2195)
V = 12.68° to the nearest hundredth
The value of the cosine of ∠V is 0.98
How to determine the value of the cosine of ∠V?The given parameters are:
∠W=90°, VU = 41, UW = 9,WV = 40The cosine of V is calculated using:
cos(V) = WV/VU
So, the equation becomes
cos(V) = 40/41
Evaluate
cos(V) = 0.98
Hence, the value of the cosine of ∠V is 0.98
