Which equation is y = –6x2 + 3x + 2 rewritten in vertex form?
y = negative 6 (x minus 1) squared + 8
y = negative 6 (x + one-fourth) squared + thirteen-eighths
y = negative 6 (x minus one-fourth) squared + nineteen-eighths
y = negative 6 (x minus one-half) squared + seven-halves
Answer:
Step-by-step explanation:
y = negative 6 (x minus one-fourth) squared + nineteen-eighths
Step-by-step explanation:
y = –6x^2 + 3x + 2
Divide the first 2 terms of the right side by -6:
y = -6(x^2 - 1/2x) + 2
Now complete the square on the expression in the brackets:
y = -6[(x - 1/4)^2 - 1/16] + 2
y = -6(x - 1/4)^2 + 6/16 + 2
y = -6(x - 1/4)^2 + 38/16
y = -6(x - 1/4)^2 + 19/8

(sqrt2-i)^6Simplify the complex numbers and arrange them in increasing order of their absolute value (modulus).
The increasing order of the complex numbers is (√2 - i)⁶ < (√2 - √2i)⁸ = (√3 - i)⁶ = (-1 + √3i)¹² < (√3 - √3i)⁴.
Absolute values of the complex numbersThe absolute values of the complex numbers are determined as follows;

[tex]|z| = \sqrt{(\sqrt{3} )^2 + (\sqrt{3 }\times1 )^2} } \\\\|z| = \sqrt{6}[/tex]
(-1+sqrt3i)^12 = (-1 + √3i)¹²
[tex]|z| = \sqrt{(-1)^2 + (\sqrt{3)^2} } \\\\|z| = \sqrt{4} \\\\|z| = 2[/tex]
(sqrt 3-i)^6 = (√3 - i)⁶
[tex]|z| = \sqrt{(\sqrt{3})^2 + (-1)^2 } \\\\|z| = \sqrt{4} \\\\|z| = 2[/tex]
(sqrt2-sqrt2i)^8 = (√2 - √2i)⁸
[tex]|z| = \sqrt{(\sqrt{2} )^2 + (\sqrt{2})^2 } \\\\|z| = 2[/tex]
(sqrt2-i)^6 = (√2 - i)⁶
[tex]|z| = \sqrt{(\sqrt{2})^2 + (-1)^2} } \\\\|z| = \sqrt{3}[/tex]
Increasing order of the complex numbers;
(√2 - i)⁶ < (√2 - √2i)⁸ = (√3 - i)⁶ = (-1 + √3i)¹² < (√3 - √3i)⁴.

Which point on the number line could represent Negative 2 and one-fourth? A number line going from negative 5 to positive 5. Point A is between negative 4 and negative 3, point B is between negative 3 and negative 2, point C is between negative 2 and negative 1, point D is between negative 1 and 0. A B C Dm
Answer:
Point B
Step-by-step explanation:
Let's take your number line from -5 to +5
The point on the number line is -2 1/4
Point A is between -4 and -3, Point B is between -3 and -2, Point C is between -2 and -1, and Point D is between -1 and 0. Because -2 is not between -4 and -3 or -1 and 0, it has to be either Point B or C. Since -2 has a fraction of 1/4, it is between Point B. It would be Point C if it was -1 1/4 and not -2 1/4.

Surface area and volume of cone
The surface area and the volume of the cone is 816.4 km² and 7536 km³ respectively.
What is volume?Volume is the capacity of an object.
To calculate the surface area and volume of the cone shown above, we use equation 1 and equation 2 respectively.
Formula:
S = πr√(r²+h²)............. Equation 1V = πr²h.................. Equation 2Where:
S = Surface area of the coneV = Volume of the coner = Radius of the base of thye coneh = Vertical height of the cone.From the diagram,
Given:
r = 10 kmh = 24 kmπ = 3.14Substitute these values into equation 1 and equation 2 respectively.
S = 3.14×10[√(24²+10²)S = 31.4(√676)S = 31.4×26S = 816.4 km²Also for the volume of tyhe cone
V = 3.14×10²×24V = 7536 km³Hence, The surface area and the volume of the cone is 816.4 km² and 7536 km³ respectively.

A circle has a circumference of 6. It has an arc of length 1.
What is the central angle of the arc, in degrees?
========================================================
Explanation:
The circumference is the perimeter of the circle. It's the distance around the circle's edge. Think of it like a fence.
The full circle's perimeter is 6 units. The arc length is a piece of that and it's 1 unit.
1/6 of the full perimeter is the arc length
1/6 of a full 360 degree rotation is (1/6)*360 = 360/6 = 60
The central angle of the arc is 60 degrees.
------------
If you want to use a formula, it would be
[tex]A = \frac{L}{C}*360[/tex]
where,
A = central angle of the arc
L = arc length
C = circumference
You would plug in L = 1 and C = 6 to find that A = 60

Segment AB has point A located at (4,2). If the distance from A to B is 3 units, which of the following could be used to calculate the coordinates for point B?
3 = √(x - 2)²+(y - 4)^2
3= V(x-4)2 +(y-2)^2
3 = V(x + 2)2 + (y+4)^2
3=(x+4)^2+(y+2)^2
The equation to calculate the coordinates of point B is (b) 3 = √(x - 4)²+(y - 2)²
How to determine the equation?The given parameters are:
A = (4,2)
AB = 3
The distance formula is:
AB = √(x - x1)²+(y - y1)²
So, we have:
3 = √(x - 4)²+(y - 2)²
Hence, the equation to calculate the coordinates of point B is (b) 3 = √(x - 4)²+(y - 2)²

Then, you find the slope(m).
So, m = y2 - y1

if y2 is 4 and y1 is 0
x2 is -3 and y1 is 0
now you subtract to get -4

What is the Volume of a Triangular Prism?Volume = base area × height of prism = 1/2(bh) × H
A. Volume = 1/2(bh) × H = 1/2(6)(8) × 5 = 120 units³
B. Volume = 1/2(bh) × H = 1/2(6)(14) × 17 = 714 units³
C. Volume = 1/2(bh) × H = 1/2(12)(8) × x = 2,688 units³
48x = 2,688
x = 2,688/48
x = 56 units (height of the prism)
D. Volume = base area × height of prism
Plug in the given values
27.36 = base area × 2.88
27.36/2.88 = area of triangular base
area of triangular base = 9.5 units².
E. Volume = 1/2(bh) × H = 1/2(8)(15) × x = 3,360 units³

The cost of 3 rackets and 2 squash balls is £26.57.
The cost of 5 rackets and 7 squash balls is £52.90.
Work out the cost of
a) a squash ball.
b) a racket
Taking into account the definition of a system of linear equations:
the cost of a squash ball and a racket are £2.35 and £7.29 respectively.the cost of 1 kg of radishes and 1 kg of carrots are £3.1 and £1.6 respectively.System of linear equationsA system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.
Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. That is to say, the values of the unknowns must be sought, with which when replacing, they must give the solution proposed in both equations.
Cost of a squash ball and a racketIn this case, a system of linear equations must be proposed taking into account that:
"x" represents the cost of a squash ball."y" represents the cost of a racket.The cost of 3 rackets and 2 squash balls is £26.57.
The cost of 5 rackets and 7 squash balls is £52.90.
So, the system of equations to be solved is
[tex]\left \{ {{2x+3y=26.57} \atop {7x+5y=52.90}} \right.[/tex]
There are several methods to solve a system of equations, it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.
In this case, isolating the variable x from the first equation:
[tex]x=\frac{26.57 - 3y}{2}[/tex]
Substituting the expression in the second you get:
[tex]7\frac{26.57 - 3y}{2}+5y=52.90[/tex]
Solving:
[tex]\frac{7}{2}(26.57 - 3y)+5y=52.90[/tex]
[tex]\frac{7}{2}x26.57 - \frac{7}{2}x3y+5y=52.90[/tex]
92.995 - 10.5y +5y= 52.90
92.995 - 5.5y= 52.90
- 5.5y= 52.90 -92.995
- 5.5y= -40.095
y= (-40.095)÷ (-5.5)
y= 7.29
So: [tex]x=\frac{26.57 - 3y}{2}=\frac{26.57 - 3x7.29}{2}[/tex]
x= 2.35
Finally, the cost of a squash ball and a racket are £2.35 and £7.29 respectively.
Cost of 1 kg of radishes and 1 kg of carrotsIn this case, a system of linear equations must be proposed taking into account that:
"x" represents the cost of 1 kg of radishes."y" represents the cost of 1 kg of carrots.The cost of 4 kg of radishes and 1.5 kg of carrots is £14.80.
The cost of 3 kg of radishes and 2 kg of carrots is £12.50.
So, the system of equations to be solved is
[tex]\left \{ {{4x+1.5y=14.80} \atop {3x+2y=12.50}} \right.[/tex]
You can solve this system using the substitution method. Isolating the variable x from the first equation:
[tex]x=\frac{14.80 - 1.5y}{4}[/tex]
Substituting the expression in the second you get:
[tex]3\frac{14.80 - 1.5y}{4}+2y=12.50[/tex]
Solving:
[tex]\frac{3}{4}(14.80 - 1.5y)+2y=12.50[/tex]
[tex]\frac{3}{4}x14.80 - \frac{3}{4}x1.5y+2y=12.50[/tex]
11.1 - 1.125y +2y= 12.50
- 1.125y +2y= 12.50 - 11.1
0.875y= 1.4
y= 1.4 ÷0.875
y=1.6
So: [tex]x=\frac{14.80 - 1.5y}{4}=\frac{14.80 - 1.5x1.6}{4}[/tex]
x= 3.1
Finally, the cost of 1 kg of radishes and 1 kg of carrots are £3.1 and £1.6 respectively.

h(x) = -5|x| + 10 -> f(0) = 10 -> Greater than g(x).
j(x) = -4(x + 2)² + 8 = f(0) = -8.
k(x) = 0.25(x - 4)² + 4 -> f(0) = 8 -> Greater than g(x).

Answer:
The surface area of the regular triangular pyramid is 108 square centimetres.
Step-by-step explanation:
What is a regular triangular pyramid?
A triangular pyramid is a three-dimensional shape that has a triangular base and three triangular faces.
The lateral surface area is the area of all the sides of a 3-dimensional object excluding its base and top.
The surface area of a triangular pyramid is the sum of the areas of the four faces of the pyramid.
What is the surface area?
The area of one face = lateral surface area / 3
81 / 3 = 27
The surface area = 27 x 4 = 108
