Help Please Solve For X:

Answers

Answer 1

Answer:

7

Step-by-step explanation:

This shape is Kite.

Properties of Kite : -

In Kite, any 1 adjacent side is equal.

So,

5x + 5 = 40

5x = 40 - 5

5x = 35

x = 35 / 5

x = 7

Answer 2

Answer:

x = 7

Step-by-step explanation:

In kite, adjacent sides are congruent.

5x + 5 = 40

Subtract 5 from both sides

5x = 40 - 5

5x = 35

Divide both sides by 5

x = 35/5

x = 7

Answers

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

find <ABC =2x and <CBD=3x-10​

Answers

Answer:

x = 20

Step-by-step explanation:

m<ABC and m<CBA are complementary angles which means their sum is 90 degrees:

2x + 3x - 10 = 90 add like terms

5x - 10 = 90 add 10 to both sides

5x = 100 divide both sides by 5

x = 20 to find the angles replace x with 20

m<ABC = 40 and

m<CBA = 50

The ___ of a parabola is the line, along with a point not on the line, which is used to generate a parabola.

Answers

Answer:

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."

The diameter of a circle has endpoints S(2, 7) and U(4, -3). What are the coordinates of the center of the circle?

Answers

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)

Find d²y / dx², dy / dx for the curve whose equation is x² + y²_3xy_6x + 5y + 2 = 0 at the point (2,3)​

Answers

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
