Answers

Answer 1

Answer:

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.

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

f(n) = 2• (-3)^n

complete the recursive formula of f(n).

f(1) = ____
f(n) = f(n - 1) • ____

Answers

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

Answers

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.

To prove this equation non-negative, you will have to convert the equation in terms of perfect square form containing a,b and c.

Now,
a²+b²+c²-ab-bc-ca
= ½ • ( 2a²+2b²+2c²-2ab-2bc -2ca )
= ½ • ( a² -2ab +b² +b² -2bc +c² +c² -2ac +a² )
= ½ • { (a-b)² + (b-c)² + (c-a)² }

For any value of a,b,c
(a-b)² ≥ 0,
(b-c)² ≥ 0,
(c-a)² ≥ 0,

So,
a²+b²+c²-ab-bc-ca = ½ • { (a-b)² + (b-c)² + (c-a)² } ≥ 0 i.e. Non-negative [ proved ]

Which is the best first step when solving the following system of equations?
5C+40= 10
3C+2d=16

Answers

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

-2 would be your answer
