Answer: 4 pairs

Step-by-step explanation:

Given

Profit on selling 'x' pairs of shoes is P(x)=-4x^2+32x-39

Find the derivative of the function to find out the critical points

\Rightarrow -8x+32=0\\\Rightarrow x=4

Thus, for 4 pair of shoes profit is maximize.

Eigh has a piece of rope that is 6 2/3 feet long. How do you write 6 2/3 as a fraction greater than 1.
Vlad [161]

Answer: 20/3

Step-by-step explanation:

To write 6 2/3 as a fraction greater than 1, we simply have to convert it from a mixed fraction to an improper fraction. This will be:

6 2/3 = [(6 × 3) + 2]/3

= (18 + 2)/3

= 20/3

Therefore, the answer is 20/3.

Can sum one help and pls show work I don’t understand
makkiz [27]

Answer:

well the to find slope you do y_2-y_1/x_2-x_1

Step-by-step explanation:

so you pick 2 sets of points I'm going to do (1,3) and (2,6) so that will be 6-3/2-1 which leaves you with 3/1x which is going to be 3x and that as a line will be y=3x+0 or y=3x because the y intercept is 0 and the slope is 3x so to graph that you all you have to do is plot the points in the table on to the graph or you go to (0,0) and go up 3 and to the right 1 and down 3 and left 1 but id rather plot the points. and that's all you have to do.

Help please? ill appreciate it a lot!

2 supplementary angles equal 180 degrees.

Let the asupplementary angle = X

Then from the problem the other angle = 3X-8 ( 3 times the supplementary angle minus 8)


So now you have X + 3X-8 = 180 degrees.

Combine the like terms:

4X -8 = 180

Add 8 to both sides:

4X = 188

Divide both sides by 4:

X = 188 / 4


X = 47 ( Supplementary angle).


The angle you want is 8 less than 3 times that:


3 *47 = 141 - 8 = 133 degrees

The function h(x) is a transformation of the square root parent function,
Contact [7]

Answer:

The equation of the transformed function is:

h\left(x\right)\:=\:\sqrt{x-3}

Step-by-step explanation:

We know that horizontal translation is of the form

  • f(x-h)

where h is a constant

  • When 'h' is positive, the function is shifted to the right.
  • When 'h' is negative, the function is shifted to the left.

From the given function, it is clear that h(x) is the horizontal translation. In other words, h(x) is the result of the horizontal shift of 3 units to the right.

Thus, the equation of the transformed function is:

h\left(x\right)\:=\:\sqrt{x-3}
