Consider we need to find the equation of the parabola.

Given:

Parabola with focus (2, 1) and directrix x=-8.

To find:

The equation of the parabola.

Solution:

We have directrix x=-8. so, it is a horizontal parabola.

The equation of a horizontal parabola is

[tex](y-k)^2=4p(x-h)[/tex]           ...(i)

where, (h,k) is center, (h+p,k) is focus and x=h-p is directrix.

On comparing focus, we get

[tex](h+p,k)=(2,1)[/tex]

[tex]h+p=2[/tex]          ...(ii)

[tex]k=1[/tex]

On comparing directrix, we get

[tex]h-p=-8[/tex]         ...(iii)

Adding (ii) and (iii), we get

[tex]2h=2+(-8)[/tex]

[tex]2h=-6[/tex]

Divide both sides by 2.

[tex]h=-3[/tex]

Putting h=-3 in (ii), we get

[tex]-3+p=2[/tex]

[tex]p=2+3[/tex]

[tex]p=5[/tex]

Putting h=-3, k=1 and p=5 in (i), we get

[tex](y-1)^2=4(5)(x-(-3))[/tex]

[tex](y-1)^2=20(x+3)[/tex]

Therefore, the equation of the parabola is [tex](y-1)^2=20(x+3)[/tex].

Answer:

The value of x = 20

Step-by-step explanation:

Given the expression

[tex]\frac{4}{5}x\:-\:\frac{1}{4}x\:=\:11[/tex]

The L.C.M of 5,4: 20

Multiply by LCM = 20

[tex]\frac{4}{5}x\cdot \:20-\frac{1}{4}x\cdot \:20=11\cdot \:20[/tex]

Simplify

[tex]16x-5x=220[/tex]

[tex]11x=220[/tex]

Divide both sides by 11

[tex]\frac{11x}{11}=\frac{220}{11}[/tex]

[tex]x=20[/tex]

Therefore, the value of x = 20

Answer:

the answer is A, connect the point with a line through the center of the circle

Step-by-step explanation:

Create another circle with the same radius as the original. Technology doesn't require this step. Lines, intersections, and circles with the centre and provided point are the steps.

When building an inscribed hexagon with technology, this step is skipped: Make a circle with the same radius as the first.

The following steps are used to build an inscribed hexagon: Create a circle using the centre with a point tool to illustrate the circumscribed circle.

Connect the point with a line through the circle's centre to create its diameter.

Mark the intersections of the two circles (the hexagon's vertices).

Form the inscribed hexagon by connecting the marked spots.

The typical method for building an inscribed hexagon does not involve making a circle with the same radius.

Step-by-step explanation:

Simple as it is, -7 is 7 degrees below 0 which means its far more negative than -4. On a number line -7 would be the farthest dot from 0 on the left which you'd want to choose.

Answer:

Approximately 3 grams left.

Step-by-step explanation:

We will utilize the standard form of an exponential function, given by:

[tex]f(t)=a(r)^t[/tex]

In the case of half-life, our rate r will be 1/2. This is because 1/2 or 50% will be left after t half-lives.

Our initial amount a is 185 grams.

So, by substitution, we have:

[tex]\displaystyle f(t)=185\big(\frac{1}{2}\big)^t[/tex]

Where f(t) denotes the amount of grams left after t half-lives.

We want to find the amount left after 6 half-lives. Therefore, t = 6. Then using our function, we acquire:

[tex]\displaystyle f(6)=185\big(\frac{1}{2}\big)^6[/tex]

Evaluate:

[tex]\displaystyle f(6)=185\big(\frac{1}{64}\big)\approx2.89\approx 3[/tex]

So, after six half-lives, there will be approximately 3 grams left.

Answer:

28

Step-by-step explanation:

44/100×x=22

x=50

x=total goals scored

50-22=28

Dimitri and his partner scored a total of points will be are 50. So, his part scored points will be 28.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

Dimitri scored 44% of the places in a two-man b-ball game against another group. His accomplice scored the other focuses. On the off chance that Dimitri scored 22 focuses the number of focuses that did his accomplice score.

Let 'x' be the total scored. Then the equation is given as,

44% of x = 22

0.44x = 22

x = 50

The points scored by his partner will be given as,

⇒ 50 - 22

⇒ 28

Dimitri and his accomplice scored a sum of focuses will be 50. In this way, his part scored focus will be 28.

Answer:

The width  of the rectangle is 14'8",  and the length is 33'4"

Step-by-step explanation:

We're given two pieces of information:

The length is eight more than twice the width:

[tex]l = 2w + 4[/tex]

The perimeter is 96 feet:

[tex]p = 96[/tex]

We also need to apply one more piece of information that is not provided here, and that is the relationship between the perimeter of a rectangle, and it's length and width:

[tex]p = 2l + 2w[/tex]

We can solve for w by plugging the other two values into the last:

[tex]p = 2w + 2l\\96 = 2w + 2(2w + 4)\\96 = 2w + 4w + 8\\88 = 6w\\3w = 44\\w = \frac{44}{3}\\w = 14\frac{2}{3}[/tex]

Now we can find the length by plugging w into the first equation:

[tex]l = 2w + 4\\l = 2(14\frac{2}{3}) + 4\\l = 29\frac{1}{3} + 4\\l = 33\frac{1}{3}[/tex]

One third of  a foot is four inches, so the width is 14'8" and the length is 33'4"

To make sure our answer is correct, we should plug those numbers back into the area equation and see if we're right:

[tex]p = 2l + 2w\\p = 2(33\frac{1}{3}) + 2(14\frac{2}{3})\\p = 66\frac{2}{3} + 29\frac{1}{3}\\p = 96[/tex]

So we know our answer's correct

Answer:

16 seconds

Step-by-step explanation:

You basically have to do all numbers times 2

The required time the electric clock would take to sound 6 times is 16 seconds at 6:00.

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

Here,
It takes 8 seconds for an electric clock to sound 3 times, so it takes,
= 8 / 3 = 2.67 seconds to sound once.

Therefore, the time it would take
= 2.67 × 6
= 16 seconds

Thus, the required time the electric clock would take to sound 6 times is 16 seconds at 6:00.
