can someone help me plz

After transforming f (x) = 2x2 + 4x + 3 into vertex form, the vertex is easily identifiable. Which ordered pair is the vertex ?

A. (0,3)

B. (1,1)

C. (-1,1)

OD. (-3,0)

Step-by-step explanation:

C.(-1,1)

Answer:

[tex]\sqrt{29} ,6,2\pi ,3\sqrt{8}[/tex]

Step-by-step explanation:

Hello there!

First lets find the value of each irrational number

[tex]6 = 6\\\\\sqrt{29} =5.385164807\\\\2\pi =6.283185307\\\\3\sqrt{8} =8.485281374[/tex]

now we can easily put them in order from least to greatest

5.3,  6,   6.2,  8.4

then we change it to its irrational form

so the correct order would be

[tex]\sqrt{29} ,6,2\pi ,3\sqrt{8}[/tex]

Answer:

  C.  12 m wide

Step-by-step explanation:

We note that the difference in dimensions is 4 m. This difference will remain the same when both sides are increased by the same amount. If x represents the short side, then the larger area is ...

  x(x +4) = 192

  x^2 +4x + 4 = 196 . . . . add 4 to complete the square

  (x +2)² = 14²

  x = 14 -2 = 12 . . . . . . . . positive square root

The new garden will be 12 m wide.

Answer:

10²

Step-by-step explanation:

Another way of phrasing "10 sets of 10 sit-ups" is "10 sit-ups, 10 times," or mathematically, 10 x 10. Another way of writing repeated multiplication is through exponents. Since we have 2 10's multiplied together, we can rewrite our expression as 10².

Answer:

10 to the power of 2

Step-by-step explanation:

10 to the power of 2 is 100 because you multiply 10x10 2 times  Hope this helps

Answer:

15 ft

Step-by-step explanation:

This is another classic case of Pythagoras theorem. To start with, let's assume that the length of the ladder we're looking for is x

We're told that the height of the building the ladder is leaning on is, x - 3

Also we're told that the distance at an adjacent from the ladder is 9 ft.

If we use Pythagoras theorem, we have

x² = (x - 3)² + 9²

x² = x² - 6x + 9 + 81

On rearranging, we have

x² - x² = -6x + 90

6x = 90

x = 90 / 6

x = 15 ft

Therefore, the length of the ladder is found to be 15 ft

Answer:

B. {–3, 5.9, 8.3}

Step-by-step explanation:

The domain is the set of all the values of  

x .The range is the set of all the values of  y .

Domain: { 3.2 , 7.6 , 1.4 , − 9.1 }

Range: { − 3 , 5.9 , 8.3 }

Answer:

range is -3, 5.9 , 8.3

Step-by-step explanation:

{(3.2, –3), (7.6, 5.9), (1.4, –3), (–9.1, 8.3)}

We are given with set of ordered pairs (x,y)

In each ordered pair, x is the domain and y is the range

for domain , take all the x  values (first number) from the ordered pairs

for range, take all the y value (second number) from the ordered pairs

y values of the ordered pairs are -3, 5.9, -3, 8.3

So range is -3, 5.9 , 8.3

Answer:

19.6375 mm^2

Step-by-step explanation:

Given data

Diameter = 5mm

Radius= 5/2= 2.5mm

The expression for the area

A=πr^2

Substitute

A=3.142*2.5^2

A=3.142*6.25

A=19.6375 mm^2

Answer:

Graph B

Step-by-step explanation:

I typed the equation into Desmo and added a negative and that was the result.

Answer:

a)

The point that is equidistant to all sides of a triangle is called the incenter.

The incenter is located at the intersection of bisectors of the interior angles of a triangle.

b)

The point that is equidistant to all vertices of a triangle is called the circumcenter.  

The circumcenter is located at the intersection of perpendicular bisectors of the sides of a triangle.

c)

See the attachment

The blue lines and their intersection shows the incenter.

The red lines and their intersection shows the circumcenter.

As we see the red point- the circumcenter is closer to vertex B.

Answer:

b=47

47+a=180

a=180-47

a=133

c+b=180(but b is equal to 47)

c+47=180

c=180-47

c=133
