Answer:

[tex]x^2 = 2y[/tex] --- equation

[tex](x,y) = (0,\frac{1}{2})[/tex] --- focus

[tex]y = -\frac{1}{2}[/tex] --- directrix

[tex]Width = 2[/tex] ---- focal width

Step-by-step explanation:

Given

[tex]depth = 2[/tex]

[tex]diameter = 4[/tex]

Required

The equation of parabola

The depth represents the y-axis. So:

[tex]y = 2[/tex]

The diameter represents how the parabola is evenly distributed across the x-axis.

We have:

[tex]diameter = 4[/tex]

-2 to 2 is 4 units.

So:

[tex]x = [-2,2][/tex]

So, the coordinates of the parabola is:

[tex](-2,2)\ and\ (2,2)[/tex]

The equation of the parabola is calculated using:

[tex]x^2 = 4py[/tex]

Substitute (-2,2) for (x,y)

[tex](-2)^2 = 4p*2[/tex]

[tex]4 = 8p[/tex]

Divide by 8

[tex]p = \frac{4}{8}[/tex]

[tex]p = \frac{1}{2}[/tex]

So, the equation is:

[tex]x^2 = 4py[/tex]

[tex]x^2 = 4 * \frac{1}{2} * y[/tex]

[tex]x^2 = 2y[/tex]

The defining features

(a) Focus

The focus is located at:

[tex](x,y) = (0,p)[/tex]

[tex](x,y) = (0,\frac{1}{2})[/tex]

(b) Directrix (y)

[tex]y = -p[/tex]

[tex]y = -\frac{1}{2}[/tex]

(c) Focal width

[tex]Width = 4p[/tex]

[tex]Width = 4*\frac{1}{2}[/tex]

[tex]Width = 2[/tex]

Explanation:

E = event space = {5,6}

The event space represents the set of all things we want to happen: namely rolling a 5 or a 6, since they are larger than 4.

S = sample space = {1,2,3,4,5,6}

The sample space is the set of all possible outcomes, whether we want them to happen or not. We have 6 possible outcomes.

Divide the number of items in each set

n(E) = 2

n(S) = 6

probability = n(E)/n(S) = 2/6 = 1/3

There's a 1 in 3 chance of rolling a number greater than 4.

Answer:

x = -5 ±4sqrt(2)

Step-by-step explanation:

(x+5)²=32

Take the square root of each side

Sqrt((x+5)²)=±sqrt(32)

x+5 = ±sqrt(16*2)

x+5 = ±4sqrt(2)

Subtract 5 from each side

x+5-5 = -5 ±4sqrt(2)

x = -5 ±4sqrt(2)

Answer:

-1049

Step-by-step explanation:

Let's assume it's a arithmetic sequence

a_1 = -26

d = a_2-a_1 = -11

==> a_94 = a_1+93*d = -1049

Answer:

-1071

Step-by-step explanation:

Let the common difference be 'd'.

d is 11

Find the difference from a (first term) and 11

Then use (n-1)

Answer:

angle KPN=95 degree

Step-by-step explanation:

angle KPN = angle JPO (because they are vertically opposite angles)

Now,

angle JPO+angle LOP=180 degree(being co interior angles)

angle JPO + 85 =180

angle JPO =180-85

angle JPO =95

since angle JPO is equal to KPN ,angle KPN is 95 degree

Answer:

Option 3 : ∠BAC = 60°

Step-by-step explanation:

Exterior angle = sum of interior opposite angles.

That is ,

            2x + 3x = 150°

              5x = 150°

                  x = 30

∠BAC = 2x = 2 × 30 = 60°

Answer:

The measure of <BAC is 60

Answer:

y = 2x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2 , then

y = 2x + c ← is the partial equation

To find c substitute (3, 5) into the partial equation

5 = 6 + c ⇒ c = 5 - 6 = - 1

y = 2x - 1 ← equation of line

Answer:

[tex] {x}^{2} + 2x + 1 = 17 \\ {x}^{2} + 2x - 16 = 0 \\ x = \frac{ - b± \sqrt{ {b}^{2} - 4ac} }{2a} \\ x = \frac{ - 2± \sqrt{68} }{2} \\ x = \frac{ - 2±2 \sqrt{17} }{2 } \\ x = - 1± \sqrt{17} [/tex]

Step-by-step explanation:

Given

Two lines are [tex]4x+3y=6[/tex] and [tex]6x+2y=10[/tex]

Two lines [tex]a_1x+b_1y=c_1[/tex] and [tex]a_2x+b_2y=c_2[/tex] will intersect when

[tex]\dfrac{a_1}{a_2}\neq \dfrac{b_1}{b_2}[/tex]

for the given lines

[tex]a_1=4,a_2=6,b_1=3,b_2=2[/tex]

[tex]\therefore \dfrac{4}{6}\neq \dfrac{3}{2}\\\\\dfrac{2}{3}\neq\dfrac{3}{2}[/tex]

Hence, lines are intersecting

Step-by-step explanation:

Answer: [tex]\dfrac{49}{50}[/tex]

Step-by-step explanation:

Given

Length of the stick is [tex]2y\ m[/tex]

A piece of [tex]4y\ cm[/tex] is cut

We know, 1 m=100 cm

So, [tex]2y\ m[/tex] in cm is [tex]200y\ cm[/tex]

Remaining length after cut is

[tex]\Rightarrow 200y-4y=196y[/tex]

Fraction of length that is left after the cut is

[tex]\Rightarrow \dfrac{196y}{200y}\\\\\Rightarrow \dfrac{49}{50}[/tex]

Thus, [tex]\frac{49}{50}[/tex] fraction of original stick remains after cut

Step-by-step explanation:

Answer:

Base = 7

Height = 10

Area = 35

Step-by-step explanation:

Area is 35.

7 * 10 = 70

70/2 = 35

Base = 7 (Given)

Height = 10 (Given)

Answer:

base: 7 (yd)

height: 10 (yd)

area: 35 (yd²)

Step-by-step explanation:

To find the area of a triangle, multiply the base and height, then, divide the product by 2. The quotient is the area of the triangle.

[tex]7*10=70.[/tex]

[tex]70/2=35.[/tex]

I, therefore, believe the area of this triangle is 35 yd.

Answer:

[tex]secA = \frac{65}{63}[/tex]

Step-by-step explanation:

[tex]cosec A = \frac{65}{16}\\\\sin A = \frac{1}{cosecA} = \frac{16}{65}\\\\cos^2 A = 1 - sin^2 A[/tex]

        [tex]= 1 - (\frac{16}{65})^2\\\\=\frac{4225-256}{4225}\\\\=\frac{3969}{4225}\\[/tex]

[tex]cos A = \sqrt{\frac{3696}{4225}} = \frac{63}{65}[/tex]

[tex]secA = \frac{1}{cosA} = \frac{65}{63}[/tex]

Answer:

Peter needs to get 36 problems correct to get 12 stars

Step-by-step explanation:

for every 3 correct answers, Peter gets 1 star

1/3

if he wants 12 stars he will have to get 'x' amount of questions correctly

considering this is constant, 1/3 will have to equal 12/x

[tex]\frac{1}{3} = \frac{12}{x} \\\\1x = 36\\[/tex]

1x = x, so you don't need to do anything to 36

therefore the answer is that you need to get 36 problems correct to get 12 stars

Answer:

Step-by-step explanation:

The area of 1 face is s^2

The area of 6 faces is 6s^2

6s^2 = 433.5                 Divide by 6

s^2 = 433.5 / 6

s^2 = 72.25                   Take the square root of both sides

sqrt(s^2) = sqrt(72.25)

s = 8.5

Normally you would find the volume of parallelepiped by using L * W * H

Since L W and H are all equal in a cube, the volume = s^3

S^3 = 8.5^3 = 614.125
