Answer:

c on edge

Step-by-step explanation:

just took the quiz

The equation representing the circle A is (x – 4)² + (y + 5)² = 36.

A circle is a spherical shape without boundaries or edges. A circle is a closed, curved object with two dimensions in geometry.

The general equation of circle is given by equation

( x - h )² + ( y - k )² = r²

Where,  ( h, k ) is the centre and 'r' is the radius.

As, the circle has a shift of 4 units on the +x axis.

The circle has a shift of the 5 units on the -y axis.

As, the circle has a radius of 6 units from the graph.

So, (h,k) = (4, -5).

Substitute the values of (h,k) in the general equation of the circle.

( x - 4 )² + ( y - (-5) )² = 6²

( x - 4 )² + ( y + 5 )² = 36

Therefore, the equation of circle becomes ( x - 4 )² + ( y + 5 )² = 36.

Answer:

1/2

Step-by-step explanation:

12 out of 24 is 1/2

In math, the '!' sign are used in factorial. Factorial is multiplications on numbers itself and with another numbers that less than the number itself. Example :

5! =5x4x3x2x1 or nx(n-1)x(n-2)...2x1

The table be like

Mike age        kellie age

10                     14

15                     19

20                    24

25                    29

Since Mike's sister, Kellie, is 4 years older than he is

And, Let m be Mike's age and let k be Kellie's age.

So here the equation be like

k = m + 4

Based on this we can compute the ages and fill the table

Answer:

x=3

Step-by-step explanation:

The problem can be re-written as :

[tex] \sqrt{3^{x} } \div \sqrt{3} = 3[/tex]

This is because x to the power of 1/2 is the same as the square of x.

multiply both sides by sqrt3

[tex] \sqrt{3^{x} } = 3 \sqrt{3} [/tex]

square both sides

[tex]3 ^{x} = (3)^{2} ( \sqrt{3} )^{2} [/tex]

simplify

[tex]3 ^{x} = 9 \times 3[/tex]

3 to the power of x is equal to 27

3 cubed (to the power of 3) is 27

so x is equal to 3.

hope i helped, and good luck :)

Answer:

x = 20°

Step-by-step explanation:

3x - 10° + 5x + 30° = 180° { being co-interior angles }

8x + 20 ° = 180°

8x = 180° - 20°

8x = 160°

x = 160° / 8

x = 20°

9514 1404 393

Answer:

  x = 20°

Step-by-step explanation:

For questions like this, it is helpful to remember that an exterior angle is equal to the sum of the remote interior angles.

  110° = 2x + 70°

  40° = 2x

  20° = x

_____

Similarly, ...

  y = x + 70° = 20° +70°

  y = 90°

Answer:

Step-by-step explanation:

see the image below

Step-by-step explanation:

The side that is adjacent to 60 degree and 90 degree is the shortest side.

If u know the hypoutnese you can divide it by 2 to find the shortest side. for example if the hypotenuse is 10 then the shortest side is 5

If you know the other leg you can simply just remove the entire radical and just keep the whole number to find the length of the shortest side.

The side that his the adjacent to the 30 degree and 90 degree angle is the second longest side of the triangle.

If u know the shortest side, just multiply the radical

[tex] \sqrt{3} [/tex]

to the whole number.

If you know the hypotunese, divide the hypotenuse by 2 and then multiply the radical to find the length of the second shortest side

Finally, the hypotunese is the largest side. It is the slanted side length that is adjacent to the 30 and 60 triangle.

If you know the shortest side, just multiply the side length by 2 to get the hypotenuse.

If you know the other leg, remove the radical and keep the who the number and multiply the whole number by 2.

E.x if the second longest side length is

[tex]5 \sqrt{3} [/tex]

Remove the radical so it becomes

[tex]5[/tex]

then multiply it by two to find the hypotunese.

[tex]5 \times 2 = 10[/tex]
