On khan academy the answer is right

The required shape of cross section when  slicing the cone diagonal to its base is ellipse and hyperbola.

Cross section of cone to be determine when slicing it toward diagonal to its base.

A object which is extruded and tapers from a circular base to a point.

When slicing the cone to its base its give two type of shapes depending upon the angle of inclination of slicing . The two shapes obtained is ellipse and hyperbola when cut it through diagonal to its base.

Thus, the required shape of cross section when  slicing the cone diagonal to its base is ellipse and hyperbola.

Step-by-step explanation:

To draw the graph, follow these steps:

The three inequalities given form a triangle.

The first equation, y ≤ 2x + 5, has a y-intercept at (0, 5) and a point at (-2, 1).

The second equation, y < -3x + 10, has points at (3, 1) and (2, 4).

Use two points to draw the lines.

After the lines are drawn, determine which side of the line the inequality works on. You can do this by testing points that are not on the line.

I will test each inequality using (0, 1):

y ≤ 2x + 5

0 ≤ 2 + 5

This is correct, so the inequality for y ≤ 2x + 5 will be shaded towards (0, 1).

y < -3x + 10

0 < -3 + 10

This is correct, so the inequality for y < -3x + 10 will be shaded towards (0, 1).

0 ≤ 1

This is correct, so the inequality for 0 ≤ y will be shaded upwards towards (0, 1).

The end result of this graph is all three inequalities being shaded (inwards).

The solution is a triangle with points at (1, 7), (3.33333, 0), and (-2.5, 0).

Answer:

Two solutions were found :

x =(6-√40)/2=3-√ 10 = -0.162

x =(6+√40)/2=3+√ 10 = 6.162

Step-by-step explanation:

Trying to factor by splitting the middle term

1.1     Factoring  x2-6x-1

The first term is,  x2  its coefficient is  1 .

The middle term is,  -6x  its coefficient is  -6 .

The last term, "the constant", is  -1

Step-1 : Multiply the coefficient of the first term by the constant   1 • -1 = -1

Step-2 : Find two factors of  -1  whose sum equals the coefficient of the middle term, which is   -6 .

     -1    +    1    =    0

The solutions to the equation x² + 6x + 1 = 0 are -0.177 and -5.823.

Given:

quadratic equation x² + 6x + 1 = 0

The quadratic formula states that for an equation of the form ax² + bx + c = 0, the solutions for x can be found using the following formula:

[tex]x = \dfrac{-b \pm \sqrt {(b^2 - 4ac)}}{2a}[/tex]

In our equation, a = 1, b = 6, and c = 1.

Now, let's plug these values into the quadratic formula:

[tex]x = \dfrac{-6 \pm \sqrt {(6^2 - 4(1)(1))}}{2(1)}[/tex]

x = (-6 ± √(36 - 4)) / 2

x = (-6 ± √32) / 2

Now, the two solutions for x:

1. x = (-6 + √32) / 2

      = (-6 + 5.66) / 2

      = -0.177

2. x = (-6 - √32) / 2

      = (-6 - 5.66) / 2

       -5.823

So, the solutions are -0.177 and -5.823.

Answer:

g(u) = -3/2 u + 1/4

Step-by-step explanation:

Solve for v

-12u +3 = 8v +1

Subtract 1 from each side

-12u +3-1 = 8v +1-1

-12u +2 = 8v

Divide each side by 8

-12u/8 +2/8 = 8v/8

-3/2 u + 1/4 = v

v = -3/2 u + 1/4

g(u) = -3/2 u + 1/4

Answer:

Step-by-step explanation:

Discount =5% of x = 0.05x

Price after discount = x - 0.05x  = 0.95x

Tax = 5% of 0.95x = 0.05*0.95x

Price including tax = 0.95x + 0.475x = 0.9975x

Answer:

(y²- 2y + 3) will be the answer.

Step-by-step explanation:

The given expression is (y³ - y² + y + 3) ÷ (y + 1)

By using long division method,

y + 1) y³ - y² + y + 3 (y²- 2y + 3

        y³ + y²

            - 2y² + y

            -2y² - 2y

                      3y + 3

                      3y + 3

                             0

Here the quotient is (y² - 2y + 3) and the remainder is 0.

(20, -12)

Step-by-step explanation:

it is (20, -12)

-(3/4)x+3=-12

x=20

-3/4(20)+3=-12

Answer: The slope is 4 and the y-intercept is 12.

Step-by-step explanation:

(-3,0)  and (-2,4)

find the difference in the Y values  0-4=-4

find the difference in the v- values   -3-(-2) =-1

Divide the y difference by the x difference   -4/-1 = 4 so 4 is the slope

Now to find the y intercept, use the formula y=mx + b and plot in coordinates and slope to find the y- intercept

4= 4(-2) + b

4 = -8 + b

+8    +8

b= 12  so the y intercept is 12

now the equation will be like y = 4x + 12

(-3,0)  and (-2,4)

find the difference in the Y values  0-4=-4

find the difference in the v- values   -3-(-2) =-1

Divide the y difference by the x difference   -4/-1 = 4 so 4 is the slope

Now to find the y intercept, use the formula y=mx + b and plot in coordinates and slope to find the y- intercept

4= 4(-2) + b

4 = -8 + b

+8    +8

b= 12  so the y intercept is 12

now the equation will be like y = 4x + 12
