Answer:

Step-by-step explanation:

30x 2 = 60

4 students = £60

60/4 = 15

Answer:

The answer to the question is 122.5

I assume you meant to write

x² + y² - 3xy - 6x + 5y + 2 = 0

Taking y = y(x) and differentiating both sides with respect to x with the power, product, and chain rules gives

2x + 2y dy/dx - 3y - 3x dy/dx - 6 + 5 dy/dx = 0

Solve for dy/dx :

2x - 3y - 6 + (2y - 3x + 5) dy/dx = 0

(2y - 3x + 5) dy/dx = 6 - 2x + 3y

dy/dx = (6 - 2x + 3y) / (2y - 3x + 5)

Now differentiate both sides again. Using the quotient and chain rules,

d²y/dx² = ((2y - 3x + 5) (-2 + 3 dy/dx) - (6 - 2x + 3y) (2 dy/dx - 3)) / (2y - 3x + 5)²

Expand and simplify the numerator:

d²y/dx² = (5y + 8 + (3 - 5x) dy/dx) / (2y - 3x + 5)²

Substitute dy/dx and simplify d²y/dx² :

d²y/dx² = (5y + 8 + (3 - 5x) (6 - 2x + 3y) / (2y - 3x + 5)) / (2y - 3x + 5)²

d²y/dx² = ((5y + 8) (2y - 3x + 5) + (3 - 5x) (6 - 2x + 3y)) / (2y - 3x + 5)³

d²y/dx² = (10y² + 50y - 30xy + 10x²  - 60x + 58) / (2y - 3x + 5)³

Hello there! (:

12y-32=4y

12y-4y=32

8y=32

Divide both sides by 8 in order to get y on its own:

y=4

Hope it helps!

Step-by-step explanation:

The square root of 36 and 361 are 6 and 19 respectively.

A number when taken square root gives an integer is a perfect square number.

Given, we have to find the square root of 26 and 361.

Now by prime factorization,

36 = 2×18 = 2×3×6 = 2×3×2×3 = 2×2×3×3 = 2²×3².

Now the square root of 2²×3² = √2²×√3² = 2×3 = 6.

The square root of 361 can be found by knowing the square root of 400 which is 20.

Now we'll check if 19² = 361 indeed 19×19 = 361 so, the square root of 361 is 19.

Answer:

The slope is -8/5

Step-by-step explanation:

Slope is the change of y over the change of x.

Two x and y values for example are -7, -2, 9, and 1.

You would set up the expression where you put 9-1 in the numerator and -7-(-2) in the denominator. The answer would be 8/-5.

Thus, the slope is -8/5.

Answer:

204 ounces or it is 24 ounces

Step-by-step explanation:

Sorry if it is wrong

Step-by-step explanation:

y = 2x + 1

4y - 5x = 13

4(2x + 1) - 5x = 13

8x + 4 - 5x = 13

8x - 5x = 13 - 4

3x = 9

x = 9/3

x = 3

y = 2x + 1

y = 2.3 + 1

y = 6 + 1

y = 7

(x,y) = (3,7)

What Julius did wrong is that, he added the partial products incorrectly

Julius product is given as:

2 5

1  8

-----

250

200

-----

550

The above product can be represented as (as given on Julius solution):

[tex]25 \times 18 = 250 + 200[/tex]

[tex]25 \times 18 = 550[/tex]

The actual solution using partial products

We have:

[tex]25 \times 18 = 25 \times (10 + 8)[/tex]

Expand

[tex]25 \times 18 = 250 + 200[/tex]

[tex]25 \times 18 = 450[/tex]

By comparing, we can conclude that:

Julius multiplied 25 by 10 and 25 by 8 correctly, but he added the partial products incorrectly

Answer:

Thus the center of the circle is at (3, 2)

Step-by-step explanation:

The center of the circle is also the midpoint of the diameter.  Thus we can use the midpoint formulas, as follows:

         sum of x coordinates                        sum of y coordinates

xm = ----------------------------------  and  ym = -----------------------------------

                          2                                                          2

In this case, xm = (2 + 4)/2 = 3 and ym = (7 - 3)/2 = 2

Thus the center of the circle is at (3, 2)

Directrix

Step-by-step explanation:

The directrix of a parabola is the line, along with a point not on the line (which is the focus), which is used to generate a parabola.  The directrix is parallel either to the x- or y-axis, and is perpedicular to the parabola's axis of symmetry (at x = h).      

Therefore, the correct answer is "directrix."
