The function that represents a parabola with vertex at (2,1) and y-intercept (0,3) is f(x) = - x² + 4x - 3.

What is general equations of parabola?

The general equation of a parabola is given by

⇒ y = a(x – h)² + k

A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line which is known as the directrix.

According to the question,

⇒ y = a(x – h)² + k

⇒ (h,k) = (2,1)

⇒  y = a(x – 2)² + 1

T find the value of a,

⇒ - 3 = 4a + 1

⇒ a =-1

⇒  y = -1(x – 2)² + 1

⇒ y = -(x² + 4 - 4x) + 1

⇒ y = -x² + 4x - 3

Hence the required function is y = -x² + 4x - 3.

Answer:

-4x  = 7

3x+5y = -9

Step-by-step explanation:

This is an augmented matrix which means the solution to the equations are on the right hand side

-4x +0y = 7

3x+5y = -9

We can remove the 0 term

-4x  = 7

3x+5y = -9

Answer:

A.

3x + 3y = 0

7x − y = 8

Step-by-step explanation:

Given

3x + 3y = 0

-4x + 4y = -8

Required

Find the equivalent

To solve for the equivalent we simply solve for x and y in the given equation.

Subtract 3x from both sides in 3x + 3y = 0

3x - 3x + 3y = 0 - 3x

3y = -3x

Multiply both sides by ⅓

⅓ * 3y = -3x * ⅓

y = -x

Substitute -x for y in -4x + 4y = -8

-4x + 4(-x) = -8

-4x -4x = -8

-8x = -8

Multiply both sides by -⅛

-⅛ * -8x = -⅛ * -8

x = 1

Recall that y = -x

y = -1

So, we have that x = 1 and y = -1

We'll substitute these values in the list of options;

A.

3x + 3y = 0

7x − y = 8

7(1) - -(1) = 8

7 + 1 = 8 ----- This is equivalent

B.

3x + 3y = 0

−7x − y = 8

-7(1) - (-1) = 8

-7 + 1 = 8

-6 ≠ 8 .... This is not an equivalent expression

C.

3x + 3y = 0

−7x + 7y = 8

-7(1) + 7(-1) = 8

-7 -7 = 8

-14 ≠ 8 .... This is also not an equivalent expression

D.

3x + 3y = 0

-4x + 7y = 8

-4(1) + 7(-1) = 8

-4 -7 = 8

-11 ≠ 8 -_- This is also not an equivalent expression

Answer:

x=56 degrees interior angle of regular hexagon is 60 degrees

Step-by-step explanation:

The sum of the angles in a hexagon is 720.  So the size of an angle in a regular hexagon is 120 degrees.

angle BCA + angle x + angle DCE are equal to 180 degrees when added together.

We can use base angles theorem to find angle DCE : 180-32 = 148 148/2 = 74

Now we know that angle BCA + angle x = 180-74= 106 degrees. Since ABC is equilateral we alread know angle BCA is 60 degrees.  Now we can find x from doing 106-60 which equals 56 degrees.

x=56

Answer:

C.

Step-by-step explanation:

Explicit Formula: an = a1(r)^(n-1)

Our r = 1/4 because to get 64 down to 16 you need to divide by 4 or multiply by 1/4

Our a1 is the 1st term of the sequence, which is 64.

Plug it in: an = 64(1/4)^(n-1)

So our only viable option is C.

Answer:

Option C

Step-by-step explanation:

=> [tex]a_{n} = a_{1} * r^{(n-1)[/tex]

Where a1 = 64, r = 1/4

So,

=> [tex]a_{n} = 64 * (\frac{1}{4}) ^{n-1}[/tex]

Answer:

D

Step-by-step explanation:

Answer:

Let humans be x and horses be y

Both have one head each,so x+y=74 (1)

Humans have 2 legs each and horses 4 legs each…… so 2x+4y=196 (2)

In first equation x+y=74 then y=74~x (3) ……… .By solving both equations we have as under… x+3y=122 x=122-3y (4)…. Now in equation 4 we put the value of y taken from equation 3 so it will be x=122~3(74-x)…. x=122-222+3x…………. bringing x on one side x-3x=122~222 therefore -2x=~100….. x=50… put the value of x in first equation… x+y=74… 50+y=74… y=74~50…..… y=24… Now it is concluded that Humans are 50 and Horses are 24.. Now you put the values of x & y in 1st and 2nd equation … you will get x+y=74.. 50+24=74………..2x+4y=196…2×50+4×24=196.. it is proved thru equation.

Answer:

2.92%

3.85%

Step-by-step explanation:

The population in 2000 is 282,194,308.  The population in 2003 is 290,447,644.  This is an increase of 8,253,336.

290,447,644 - 282,194,308 = 8,253,336

To find the percentage in increase, divide the difference by the original number and multiply by 100%.  The population increased by 2.92%.

8,253,336/282,194,308 = 0.0292 × 100% = 2.92%

The population in 2003 is 290,447,644.  The population in 2007 is 301,621,157.  This is an increase of 11,173,513.

301,621,157 - 290,447,644 = 11,173,513

Divide the difference by the original number and multiply by 100%.  The population increased by 3.85%.

11,173,513/290,447,644 = 0.0385 × 100% = 3.85%

I think its 57.17 or about 52.2cubic inch

Answer: 22.4

Step-by-step explanation:

The distance formula can be used to solve this problem.

[tex]D=\sqrt{(x_{2}-x_{1} )^2+(y_{2}-y_{1} )^2}[/tex]

We can plug in our x and y values to find the distance.

[tex]D=\sqrt{(14-4)^2+(-11-9)^2}[/tex]

[tex]D=\sqrt{10^2+(-20)^2}[/tex]

[tex]D=\sqrt{100+400}[/tex]

[tex]D=\sqrt{500}[/tex]

[tex]D=22.4[/tex]

Our distance between the points is 22.4.

Quadrant 2

Step-by-step explanation:

The answer is quadrant two because the answer is in the form of -x,y. When the x is negative and the y is positive, it is always going to be in quadrant 2. As you can see in the image below, quadrant 1 is going to be all positive, quadrant two is going to be negative then positive, quadrant three is going to be all negative, and quadrant 4 is going to be positive then negative.
