a) What is a semi-regular tessellation? How many semi-regular tessellations are possible? Why aren’t there infinitely many semi-regular tessellations? (5 points)

Answer :

By using EDL

a=bq+r

where a is > b

so a =867 and b=255

867=255×3+102

here r≠0 so a=255 and b=102

255=102×2+51

here r≠0 so a=102 and b=51

102=51×2+0

here r=0

so, Hcf of (867,255) is =51

Step-by-step explanation:

Hope it works out!!

Answer:

[tex]51[/tex]

Step-by-step explanation:

[tex]a=bq+r[/tex]

Where [tex]a > b[/tex]

[tex]867=255 \times 3+102[/tex]

[tex]255=102 \times 2+51[/tex]

[tex]102=51 \times 2+0[/tex]

Hcf of 867,255 is 51

Answer:

[tex]a)365 \\ b)700 \\ c)76.5[/tex]

Step-by-step explanation:

[tex]a)360 + 5 \\ = 365[/tex]

Because each dash represent 10 and it's represent 5 in between of two dashes.

[tex]b)700[/tex]

Because each dash represent 100

[tex]c)76.5[/tex]

Because each dash represent 0.5

Answer:

Gradient = m = -2

Y-intercept = b = 0

Step-by-step explanation:

Compare the given equation with slope-intercept form of equation.

y = mx + b

y = -2x + 0

So، m = -2 and b = 0

Answer:

Angle 1 = 110 degrees

Angle 2 = 70 degrees

Angle 3 = 100 degrees

Angle 4 = 80 degrees

Step-by-step explanation:

We will first of all search for the pieces of information given in the question that can help us to solve the problem.

From the diagram, we can see that angle 3 and angle 4 are already given as

Angle 3 = 100 degrees

Angle 4 = 80 degrees

The value of angle 1 has already been supplied as 110 degrees. This leaves us with angle 2 to find.

Recall that the angles in a straight line all sum up to 180 degrees. angle 1 and 2 are on the same straight line, hence angle 2 can be found by solving 180 - 110 = 70 degrees

Angle 2 = 70 degrees

Answer:

B.

Step-by-step explanation:

Answer:

y = - 12x - 47

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 12x - 2 ← is in slope- intercept form

with slope m = - 12

Parallel lines have equal slopes, thus

y = - 12x + c ← is the partial equation

To find c substitute (- 4, 1 ) into the partial equation

1 = 48 + c ⇒ c = 1 - 48 = - 47

y = - 12x - 47 ← equation of parallel line

The required equation of the line is y = -12x - 47

"The equation of the line having slope m and passing through points (p, q) is (y - q) = m(x - p)"

"y = mx + c, where m is the slope and c is the Y-intercept of the line."

For given question,

We have been given a point (-4, 1)

The required line is parallel to the line y = -12x - 2

Comparing above equation with slop-intercept form of the line.

m = -12

Let m1 be the slope of the required line.

We know that the slope of parallel lines is equal.

⇒ m1 = m

⇒ m1 = -12

Now we find the equation of the required line by using slope-point form.

Let (p, q) = (-4, 1)

By using slope-point form,

⇒ (y - q) = m1(x - p)

⇒ (y - 1) = -12(x - (-4))

⇒ y - 1 = -12x - 48

⇒ y = -12x - 47

Therefore, the required equation of the line is y = -12x - 47

Answer:

-4

Step-by-step explanation:

Hello,

let say that [tex]x_1[/tex] and [tex]x_2[/tex] are two zeros of second order polynomial

it can be then be written

[tex](x-x_1)(x-x_2)=x^2-(x_1+x_2)x+x_1*x_2[/tex]

So when we check this expression

[tex]x^2+4x+7[/tex]

we can say that the sum of zeros is -4

and the the product of zeros is 7

to note that in this example there are no real root of this equation

[tex]x^2+4x+7=0[/tex]

here, the zeros are complex numbers not real ones

if I have to solve it in [tex]\mathbb{R}[/tex] I would say that there are no zeros so their sum is not defined

if I have to solve it in [tex]\mathbb{C}[/tex] I would say that there are two complex roots and their sum is -4

hope this helps

Answer:

x = -3, x = 0 is a extraneous solution

Step-by-step explanation:

Step 1: Cross-multiply

3x² = 4x² + 3x

Step 2: Isolate x's

0 = x² + 3x

Step 3: Factor

0 = x(x + 3)

Step 4: Find roots

x = 0, -3

Step 5: Double check work

Plug in both to see if they both work. Only x = 0 should be extraneous. We now have our answer!

Answer:

y -3 = -4(x+2)

Step-by-step explanation:

The point slope form of a line is

where m is the slope and (x1,y1) is a point on the line

y -3 = -4(x- -2)

y -3 = -4(x+2)
