Step-by-step explanation:
To construct the parallelogram WXYZ using a ruler and a pair of compasses, follow these steps:
Step 1: Draw a line segment XY of length 6.4 cm.
Step 2: From point X, draw an angle of 120 degrees.
Step 3: Set the compasses to a radius of 4.7 cm and draw an arc intersecting the line XY at point Y.
Step 4: From the intersection point on the arc, draw another arc intersecting the line XY at point Z.
Step 5: Draw a line segment connecting points Y and Z.
Step 6: Draw a line segment parallel to YZ, passing through point X.
Step 7: Draw a line segment parallel to XY, passing through point Z.
The resulting shape is the parallelogram WXYZ.
Now, let's address the remaining questions:
(b) Constructing the loci:
(i) Locus l1: To construct the locus of points equidistant from line XR and line XY within the parallelogram, draw perpendicular bisectors of line segments XR and XY. The intersection of these perpendicular bisectors will give you the locus l1.
(ii) Locus l2: To construct the locus of points at a distance of 4 cm from point Y, draw arcs with a radius of 4 cm centered at point Y. The locus l2 will be the arc formed.
(iii) Locus l3: To construct the locus of points equidistant from points R and Z, draw the perpendicular bisector of line segment RZ. The intersection of the perpendicular bisector with the interior of the parallelogram will give you the locus l3.
(c) Finding the intersections:
To find the intersections of locus l2 and locus l3, as well as locus c and locus D, you need to provide additional information or loci equations. Without specific instructions or equations, it is not possible to determine the precise points of intersection.
Please provide more information or equations if you need assistance with finding the intersections.

Answer:
83
Step-by-step explanation:
The sum of the interior angles of any closed figure will always equal 360º, so what you need to do is add:
109+90+78=?
This will in turn give you 277.
Subtract 277 from 360, and boom, 83 degrees.
write the fraction in ascending order.

QUESTION 1 :
find the LCM of 3,6,2,4
LCM = 12
THEREFORE,
2/3*4/4 = 8/12
5/6*2/2 = 10/12
1/2*6/6 = 6/12
3/4*3/3 = 9/12
8/12 , 10/12 , 6/12 , 9/12
Ascending order of ( 8/12 , 10/12 , 6/12 , 9/12)
= 6/12 , 8/12 , 9/12 , 10/12
So, 6/12 = 1/2
8/12 = 2/3
9/12 = 3/4
10/12 = 5/6
THEREFORE
Ascending order = 1/2 , 2/3 , 3/4 , 5/6

Frankie started cleaning her house at 1:30 p.M and finished cleaning at 6;30 p.M how long did Frankie clean
Answer:
5 hours
Step-by-step explanation:
Start time = 1:30 p.m
Finishing time = 6:30 p.m
Time taken :
Finishing time - start time
6:30 p.m - 1.30 p.m

Find the length of the third side. If necessary, write in simplest radical form. 1 2
Answer:
√3
Step-by-step explanation:
Using the pythagorean theorem, we know that a^2 + b^2 = c^2
In this case, c = 2, which means that a^2 + b^2 = 4
Since we know that a = 1, this means that a^2 is also 1. So, we know that b^2 = 4 - 1
Therefore, b^2 = 3
So, the answer is square root 3

Which is the best first step when solving the following system of equations?
5C+40= 10
3C+2d=16
Answer:
multiply the second equation by - 2
Step-by-step explanation:
Given the 2 equations
5c + 4d = 10 → (1)
3c + 2d = 16 → (2)
Multiplying (2) by - 2 and adding to (1) will eliminate d
- 6c - 4d = - 32 → (3)
Add (1) and (3) term by term to eliminate d
- c + 0 = - 22
- c = - 22 ( multiply both sides by - 1 )
c = 22
Substitute c = 22 into either of the 2 equations and solve for d
Substituting into (2)
3(22) + 2d = 16
66 + 2d = 16 ( subtract 66 from both sides )
2d = - 50 ( divide both sides by 2 )
d = - 25
solution is c = 22, d = - 25

f(n) = 2• (-3)^n
complete the recursive formula of f(n).
f(1) = ____
f(n) = f(n - 1) • ____
Answer:
[tex]f(1)=-6[/tex]
[tex]f(n)=f(n-1)(-3)[/tex]
Step-by-step explanation:
We are given that
[tex]f(n)=2\cdot (-3)^n[/tex]
We have to complete the recursive formula of f(n).
Substitute n=1
[tex]f(1)=2\cdot (-3)[/tex]
[tex]f(1)=-6[/tex]
[tex]f(2)=2\cdot (-3)^2=18[/tex]
[tex]f(3)=2\cdot (-3)^3=-54[/tex]
[tex]\frac{f(2)}{f(1)}=\frac{18}{-6}=-3[/tex]
[tex]\frac{f(3)}{f(2)}=\frac{-54}{18}=-3[/tex]
It forms geometric sequence because the ratio of two consecutive terms are equal.
Therefore, the recursive formula
[tex]f(n)=f(n-1)r[/tex]
[tex]f(n)=f(n-1)(-3)[/tex]
Answer:
f(1) = -6
f(n)= f(n−1)⋅ -3

prove that the polynomials are nonnegative a^2-2ab+b^2+c^2
Answer:
a2 + b2 + c2 - ab - bc - ca
= (1/2)(2a2 + 2b2 + 2c2 - 2ab - 2bc - 2ca)
= (1/2)(a2 - 2ab + b2 + b2 - 2bc + c2 + c2 - 2ca + a2)
= (1/2)[(a-b)2 + (b-c)2 + (c-a)2]
Now we know that, the square of a number is always greater than or equal to zero.
Hence, (1/2)[(a-b)2 + (b-c)2 + (c-a)2] ≥ 0 => it is always non-negative.
