Answer:

π + 2

Step-by-step explanation:

x² + y² - 4x - 4y + 4 = 0

(x² - 4x + 4) + (y² - 4y + 4) + 4 - 4 - 4 = 0

(x - 2)² + (y - 2)² = 4

So the radius of the circle = 2, center C(2, 2)

Are a of AMNB = area of semi-circle  - area of segment AB

= area of semi-circle - (area of quarter circle ABC - area of triangle ABC)

= area of quarter circle ABC + area of triangle ABC

= π(2)²/4 + 2*2/2

= π + 2

Answer:

[tex]135^\circ[/tex]

Step-by-step explanation:

Given that, a regular octagon is to be constructed.

To find:

Each angle in the octagon = ?

Solution:

We know that a regular triangle (polygon with 3 sides) has an interior angle of [tex]60^\circ[/tex].

And a regular quadrilateral (square) has an interior angle of [tex]90^\circ[/tex].

Therefore, formula for interior angle of a regular polygon with [tex]n[/tex] number of sides can be given as:

[tex]\dfrac{n-2}{n}\times 180^\circ[/tex]

For an octagon, we have [tex]n=8[/tex].

Value of Interior angle in a regular octagon:

[tex]\dfrac{8-2}{8}\times 180^\circ=\dfrac{6}{8}\times 180^\circ=\bold{135^\circ}[/tex]

Kindly refer to the attached image for the angle of [tex]135^\circ[/tex]

Answer:

no

Step-by-step explanation:

the sum of all 3 angles does not add up to 180 degrees, so no

Answer:

True

Step-by-step explanation:

y = -2x + 9 is already in slope-intercept form, so we can leave it be. 8x + 4y = 28, however, is not, so we have to convert it to find the answer.

To do this we have to separate the variable 4y from the rest.

We get 4y = -8x + 28.

But, y must equal zero, so to achieve this, we divide the entire equation by 4.

Then we get y = -2x + 7

Since the slopes are the same (-2x = -2x) the lines are parallel.

Answer:

(6,9)

Step-by-step explanation:

Answer:

Consider the sequence

12,4,14,7,18 ,10,⋯. Calculate the sum of the first 50 y terms of that sequence

Answer: 4x + 30

Steps: x + (x + 30) + 2x​

Remove the parentheses: x + x + 30 + 2x

Group like terms: x + x + 2x + 30

Add similar elements: 4x + 30

Answer: x=35 and y=72.5

Step-by-step explanation:

Everything os 360, so x is 35 because it los like it has the same measure as the another 35, so if you substract 70 360=290 and 290/4 = 72.5

Answer:

78.75 ft^2

Step-by-step explanation:

right triangle area

(6 X 20) ÷ 2 = 60 ft^2

left triangle area

do Pythagoras with 6 and 15:

√(15^2 - 6^2) ≈ 13.75

20 - 13.75 = 6.25

(6 X 6.25) ÷ 2 = 18.75 ft^2

total = 60 + 18.75

Answer: x=0, 13/2......

Solution:

[tex]\rightarrow \frac{4^{-3} \times 3^{4} \times 4^{2} }{3^{5} \times 4^{-2} }[/tex]

[tex]\rightarrow 4^{-3 + 2} \times 3^{4 - 5} \times 4^{2} }[/tex]

[tex]\rightarrow 4^{-1} \times 3^{-1} \times 16}[/tex]

[tex]\rightarrow \frac{1}{4} \times \frac{1}{3} \times 16}[/tex]

[tex]\rightarrow \frac{1}{12} \times 16}[/tex]

[tex]\rightarrow \frac{16}{12}[/tex]

[tex]\rightarrow \boxed{\bold{\frac{4}{3} \tex\text{ (Option B)}}}[/tex]

Answer:

[tex]\dfrac43[/tex]

Step-by-step explanation:

      [tex]\dfrac{4^{-3}\cdot3^4\cdot4^2}{3^5\cdot4^{-2}}[/tex]

Separate like terms:

[tex]\implies \dfrac{4^{-3}\cdot4^2}{4^{-2}}\cdot \dfrac{3^4}{3^5}[/tex]

Use exponent rule [tex]a^b \cdot a^c=a^{(b+c)}[/tex] :

[tex]\implies \dfrac{4^{(-3+2)}}{4^{-2}}\cdot \dfrac{3^4}{3^5}[/tex]

[tex]\implies \dfrac{4^{-1}}{4^{-2}}\cdot \dfrac{3^4}{3^5}[/tex]

Use exponent rule   [tex]\dfrac{a^b}{a^c}=a^{(b-c)}[/tex]

[tex]\implies 4^{(-1--2)}\cdot {3^{(4-5)}[/tex]

[tex]\implies 4^{1}\cdot {3^{-1}[/tex]

Use exponent rule  [tex]a^{-1}=\dfrac{1}{a}[/tex]

[tex]\implies 4\cdot \dfrac13[/tex]

[tex]\implies \dfrac43[/tex]

Answer:

b) y = - 1/4 x

Step-by-step explanation:

You can find the slope by using rise over run. And sense this is a negative line the slope must be negative as well.

Answer:

The equation of the line is y=-1/4x

Answer:

○ [tex]\displaystyle (2x + 1)(2x - 5) = 0[/tex]

Step-by-step explanation:

Find two quantities that when differed to 8, they also multiply to 20. Those will be 2 and 10. The TINIER quantity gets the plus symbol because the B-value is −8, therefore 10 gets the minus symbol, leaving 2 with the plus symbol. In extension, sinse we have a leading coefficient greater than one, we need to take extra procedures. Here is how it is done:

[tex]\displaystyle y = 4x^2 - 8x - 5 \\ \\ y = [4x^2 - 10x] + [2x - 5] \\ \:\:\:\:\:\:\:\:\:\:\:2x[2x - 5]+ 1[2x - 5] \\ \\ \boxed{[2x - 5][2x + 1] = 0}[/tex]
