What is the slope of this line?​

Answer:

The correct answer would be: "Maximum height 9 feet; horizontal distance 9 feet".

Step-by-step explanation:

I know this not only because I already took the test, BUT by graphing the equation (you can use graphing apps) it'll give you the answer.

Her maximum height is 9 feet & she is horizontally 9 feet from the end of the ramp when she lands.

The path of the skateboarder can be modelled by the equation,

(x-3)² = -4(y-9)

Now, from the equation, solving y,

(x-3)² = -4(y-9)

⇒ y-9 = -[tex]\frac{1}{4}[/tex](x-3)²

⇒ y = -[tex]\frac{1}{4}[/tex](x-3)² + 9

∴ Maximum height is 9 feet.

We have to take y = 0,

Now, -[tex]\frac{1}{4}[/tex](x-3)² + 9 = 0

        ⇒ -(x²-6x+9)+36 = 0

        ⇒ -x²+6x-9+36 = 0

        ⇒  x²-6x-27 = 0

        ⇒ x²-9x+3x-27 = 0

        ⇒ (x-9)(x+3) = 0

        ⇒ x = 9 or x = -3

Neglecting the negative value we get, x = 9

So, Her horizontal distance from end of the ramp is 9 feet.

Answer:

  non-linear

Step-by-step explanation:

The degree of this polynomial equation is the highest power of x: 3. When the degree is not 0 or 1, the relation is non-linear.

Answer:

48

Step-by-step explanation:

N₁ = 6

N(n+1) = 6*(Nn  -4 )

N₍₁₊₁₎= 6* (N₁ - 4)

N₂ = 6 *(6-4)  = 6*2

N₂ = 12

     N₍₂₊₁₎ = 6*(N₂ - 4)

      N₃ = 6*(12 -4) = 6* 8

     N₃ = 48

Yep! It is an integer!

Any negative, positive number or 0 is an integer.

Hope it helps!

0 is an integer

an integer is simply any number that does not have a decimal point and is not a fraction.

even of it has a negative sign or positive sign, it is still an integer

it can also be called a whole number

A   = 981.3 ft^2

Step-by-step explanation:

Here we're calculating the area of a semicircle of radius 25 ft.

The area of a circle is A = (pi)(r)^2, and that of a semicircle of the same radius is A = (1/2)(pi)(r)^2.

Here pi = 3.14 and r = 25 ft, and so the area/space in question is

A = (1/2)(3.14)(25)^2

A   = 981.3 ft^2

The space does Snoopy have to roam is 490.625 square feet.

Given that, Snoopy the dog is on a 25-ft long chain that is attached to the back of a barn.

The area of a sector is the space inside the section of the circle created by two radii and an arc. It is a fraction of the area of the entire circle.

The formula for the area of the sector of a circle is /360° (r²) where r is the radius of the circle and is the angle of the sector.

From the attached image, we see that snoopy is at the edge of a circle with the garage taking up a quarter of that circle.

Now, the area of space Snoopy was roaming

= 90°/360° × (3.14 × 25²)

= 1/4 × (3.14 × 625)

= 0.25 × 1,962.5

= 490.625 square feet

Therefore, the space does Snoopy have to roam is 490.625 square feet.

y  =2/3x  +  1/3

slope 2/3

y-intercept:   (0  ,1/  3)

Answer:

Step-by-step explanation:

- 2x + 3y = -1​ is the equation of a line

Pick any values for x then find y or for y and then find x;

if you have two points you can draw a line trough those two points.

For example,

pick x= -1 then find y

- 2*(-1) + 3y = -1​

         2+ 3y = -1

              3y = -1-2

                y= -3/3

                y= -1

First point has the coordinates (-1, -1)

pick y = 1 then find x

- 2x + 3*1  = -1​

      -2x +3 = -1

           -2x = -1-3

            -2x = -4

                x= -4/-2

                x= 2

Second point has the coordinate (2, 1)

Draw a line trough the points (-1, -1) and (2,1) to sketch the graph of -2x+3y = -1

Answer:

The function has a negative leading coefficient and a maximum vertex point

Explanation:

This function's leading coefficient is determined by whether it is concave up or concave down, meaning it has an Up and Up end behavior for a positive leading coefficient and a Down and Down end behavior for a negative coefficient.

This function's end behavior is Down and Down, so it must have a negative leading coefficient.

The function has a minimum vertex when the function has a positive leading coefficient and a maximum vertex point when the function has a negative leading coefficient.

This means that the functions vertex is the highest or lowest possible value of the function (the rest of the function continues forever in whichever direction.

This particular function has a maximum vertex as there is no point above the vertex here and the function has a negative leading coefficient.

Answer:

Leading coefficient: negative
