Answer:

1237t - 289

Step-by-step explanation:

Answer:

[tex]y = (x - 3)^2 - 12[/tex]

[tex](3,-12)[/tex]

Step-by-step explanation:

Given

[tex]y = x^2 - 6x - 3[/tex]

Solving (a): In vertex form

The vertex form of an equation is:

[tex]y = a(x - h)^2 + k[/tex]

To do this, we make use of completing the square method.

We have:

[tex]y = x^2 - 6x - 3[/tex]

------------------------------------------------------------------

Take the coefficient of x (i.e. -6)

Divide by 2; -6/2 = -3

Square it: (-3)^2 = 9

Add and subtract the result to the equation

------------------------------------------------------------------

[tex]y = x^2 - 6x - 3[/tex]

[tex]y = x^2 - 6x + 9 - 9 - 3[/tex]

[tex]y = x^2 - 6x + 9 - 12[/tex]

Factorize [tex]x^2 - 6x + 9[/tex]

[tex]y = x^2 - 3x-3x + 9 - 12[/tex]

[tex]y = x(x - 3)-3(x - 3) - 12[/tex]

Factor out x - 3

[tex]y = (x - 3)(x - 3) - 12[/tex]

Express as squares

[tex]y = (x - 3)^2 - 12[/tex]

Hence, the vertex form of [tex]y = x^2 - 6x - 3[/tex] is: [tex]y = (x - 3)^2 - 12[/tex]

Solving (b): State the coordinates of the vertex.

In [tex]y = a(x - h)^2 + k[/tex]; the vertex is: (h,k)

The vertex of [tex]y = (x - 3)^2 - 12[/tex] will be [tex](3,-12)[/tex]

Answer:

B

Step-by-step explanation:

It is linear and increasing.

If it is linear, it is increasing at a constant rate with a straight line.

Exponential means it is a curved line and would have an equation like f(x)=5^x

If it was decreasing, it would have a negative slope, such as -2x +10

Answer:

531.167 ft²

Step-by-step explanation:

Given data

Dimension of pool

Diameter =24ft

Radius =12ft

If the cover must hang by 1ft around, then the diameter is 26ft

Radius =13ft

Area of cover = πr²

Substitute

Area = 3.142*13²

Area =3.143*169

Area =531.167 ft²

Hence the minimum area is 531.167 ft²

Answer:

The 3rd choice.

Step-by-step explanation:

The third choice has what it takes to be a scientific notation.

Answer:

domain = 0 < x < infinity / range = y < 4

Step-by-step explanation:

Answer:

x =180-(90+46)

=180-136

=44

Answer:

44°

Step-by-step explanation:

180-90-46=44

Answer:

a= 45

Step-by-step explanation:

all angles equal 180 degrees so you take the angle given which is 45 and the other which is a right angle, or 90 degrees and subtract 45 from 90 and you get 45 so a = 45 and you add up 45 + 45 + 90 thats 180!  

Answer:

64

Step-by-step explanation:

Okay, here it goes:

Where there is a g you insert -2 and where there is an h you insert 5

(2(-2)+9(5)-5)-(6(-2)-4(5)+2)

If two numbers are side-by-side with no other sign between them, you multiply

(-4+45-5)-(6(-2)-4(5)+2)

(-4+45-5)-(-12-20+4)

There is a subtraction sign between these equations. That means you must distribute the negative sign to the equation on the right.

Remember:

-4+45-5+12+20-4

Now just add them together. I recommend going left to right.

-4+45=41

41-5=36

36+12=48

48+20=68

68-4=64

Fill the 3L jug, then pour its contents into the 5L jug.

Fill the 3L jug again, then pour as much of it (2L) as you can into the 5L jug.

Now the 5L jug is full, and the 3L jug is carrying 1L of water.

Empty the 5L jug.

Pour the 1L of water from the 3L jug to the 5L jug.

Finally, fill up the 3L jug, then transfer its water into the 5L jug. It now has 4L of water.

Answer:

32

Step-by-step explanation:

Answer:

62

Step-by-step explanation:

The sum of the angles in a triangle add to 180

L + M + N= 180

38+ 80 + N = 180

118+ N = 180

N = 180-118

N = 62

Answer:

1100000000

Step-by-step explanation:

Answer:

r = 5

Step-by-step explanation:

12 - 1/5r = 2r + 1

12 - 0.2r = 2r + 1

12 - 0.2r + 0.2r = 2r + 0.2r + 1

12 = 2.2r + 1

12 - 1 = 2.2r + 1 - 1

2.2r = 11

2.2r ÷ 2.2 = 11 ÷ 2.2

r = 5

Answer:

r = 5

Step-by-step explanation:

12- 1/5r = 2r + 1

12 = 11/5r + 1

5(11) = (11/5r)5

55 = 11r

r = 5

Answer:

???

Step-by-step explanation:

Where's the image?

Answer:

r = 0.2

Step-by-step explanation:

Given

y = rx ( divide both sides by x )

[tex]\frac{y}{x}[/tex] = r

Use any of the ordered pairs from the table and substitute

Using (8, 1. 6 ) , then

r = [tex]\frac{1.6}{8}[/tex] = 0.2

Answer:

(x+4)² + (y-k) ² = 16

Step-by-step explanation:

The equation of the circumference is expressed as;  

(x-h) ² + (y-k) ² = r²

(h,k) is the centre

r is the radius

Given that diameter = 8

radius = 8/2

radius = 4units

Given that h = -4 and k = 2

(x-h) ² + (y-k) ² = r²

(x-(-4)) ² + (y-2) ² = 4²

(x+4)² + (y-k) ² = 16

This gives the required equation

The last one

Step-by-step explanation:

[tex]x^3+1=0[/tex]

Subtract 1 from both sides

[tex]x^3+1-1=0-1[/tex]

simplify

[tex]x^3=-1[/tex]
