Find the vertex, focus, directrix, and focal width of the parabola. x = 4y2.

Answers

- Vertex : ( 0, 0 ).
- Focus: ( p/2, 0 );
y² = 1/4 x
y² = 2 p x ⇒ 2 p = 1/4
p = 1/8
p/2 = 1/16
F ( 1/16, 0)
- Directrix:
x = - p/2 x
x = - 1/16 x
- The focal length:
2 p = 2 · 1/8 = 1/4

Answer:

The vertex is (0,0), focus of the parabola is $((1)/(16),0)$ , directrix of the parabola is $y=-(1)/(16)$ , focal width is $(1)/(4)$ .

Step-by-step explanation:

The given equation of parabola is

$x=4y^2$

It can be written as

$y^2=(1)/(4)x$ ....(1)

The general equation of parabola is

$(y-k)^2=4p(x-h)$ ... (2)

Where, (h,k) is vertex, (h+p,k) is focus, y=h-p is directrix and |4p| is focal width.

On comparing (1) and (2), we get

$h=0,k=0$

The vertex is (0,0).

$4p=(1)/(4)$

$p=(1)/(16)$

Focus of the parabola is

$(h+p,k)=(0+(1)/(16),0)=((1)/(16),0)$

Therefore focus of the parabola is $((1)/(16),0)$ .

Directrix of the parabola is

$y=h-p=0-(1)/(16)=-(1)/(16)$

Directrix of the parabola is $y=-(1)/(16)$ .

Focal width is

$|4p|=|4* (1)/(16)|=(1)/(4)$

Focal width is $(1)/(4)$ .

Answer:

an= n * (n+1)

Step-by-step explanation:

2,6,12,20,.....

6-2 =4

12-6 = 6

So there is no common difference because these numbers are not the same

It cannot be an arithmetic difference

6/2 =3

12/6 =2

So there is no common ratio because these numbers are not the same

It cannot be geometric

2, 6, 12, 20,...

+4 +6 +8 +10

a1 =2

a2 =2*3

a3 = 2*6=2*2*3=3*4

a4=2*10=2*2*5=4*5

.....

a5 = 5*6 = 30

an= n * (n+1)

3

Answers

Answer:

48 metres.

Step-by-step explanation:

How far does the cyclist travel in 3 seconds:

First, find how far the cyclist goes in 1 second:

320 metres = 20 seconds

? = 1 second

320 ÷ 20 = 16 metres

The cyclist travels 16 metres in 1 second.

How far does the cyclist travel in 3 seconds:

1 second = 16 metres

3 seconds = ?

16 × 3 = 48 metres.

The cyclist travels 48 metres in 3 seconds.

What equation is solved by the graphed systems of equations?a. 3x + 4 = 5x - 10
b. 3x - 4 = 5x - 10
c. 3x + 4 = 5x + 10
d. 3x - 4 = 5x + 10

Answers

The solution on the graph is (x,y)=(7,25), so x=7.

$a. \n3x+4=5x-10 \n3x-5x=-10-4 \n-2x=-14 \nx=(-14)/(-2) \nx=7 \n \nb. \n3x-4=5x-10 \n3x-5x=-10+4 \n-2x=-6 \nx=(-6)/(-2) \nx=3 \n \n c. \n3x+4=5x+10 \n3x-5x=10-4 \n-2x=6 \nx=(6)/(-2) \nx=-3 \n \nd. \n 3x-4=5x+10 \n3x-5x=10+4 \n-2x=14 \nx=(14)/(-2) \nx=-7$

x=7 in the equation a, so the answer is A.
