Answer:

C. $30

Step-by-step explanation:

According to the first part of the equation, hourly pay is $25, up to 38 hours.

Overtime is paid over 38 hours.

Find the hourly pay for overtime, taking x = 39 and finding the difference with the total at x = 39 and x = 38, then we have the payment for one hour.

30(39 - 38) + 950 - 38*25 = 30 + 950 - 950 = 30

Given N1 = 6 and Nn+1 = 6(Nn - 4) ). Find N3.​

Answers

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

Sketch the graphs. - 2x + 3y = -1​

Answers

Answer:

Step-by-step explanation:

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

Snoopy the dog is on a 25-ft long chain that is attached to the back of a barn (see the
picture below). If the chain does not allow him to go past either of the adjacent sides
of the barn, how much space does Snoopy have to roam?
Use pi = 3.14 and round your answer to the nearest tenth.

Answers

Answer:

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.

What is the area of a sector?

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.

You want to buy a shirt that is $11.99 and the store is having a 25% off sale what do u pay for the shirt

Answers

It is 25% off so it is 75% of the price. 75/100*11.9 = 8.9925

It rounds to about $8.99

You would pay 8.99 for the shirt. You would do this because you first multiply 11.99 by 0.75 because 1.00-0.25=0.75, when you do this you end up with 8.9925 and because this is money you round to the nearest hundred, giving you the answer, 8.99.

The path of a skateboarder can be modeled by the equation (x – 3)2 = –4(y – 9), where distance is in feet and air resistance is insignificant. If the skateboarder makes a jump from a ramp at x = 0, what is her maximum height and how far is she horizontally from the end of the ramp when she lands?

Answers

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.

What is skateboarders maximum height ?

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.

How far is she horizontally from end of ramp ?

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.

Determine if the leading coefficient of the following function is positive or negative and whether the function has a minimum or maximum vertex point.

Answers

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

Maximum vertex point
