Answer:

Circle

Step-by-step explanation:

because a hyper bole is (y-k) 2b2 -(x-h) 2a2=1

ellipse is = (x-h) 2a2 + (y-k) 2b2 = 1

parabola is y= a (x-h) 2+ k

that's why circle is the answer

Equation- 8x(12+7-9)-(4+10)

Answer- 80x−14

Answer:

  C.  (1, 3)

Step-by-step explanation:

The x-coordinate of a point is the measure of the horizontal distance a point is to the right of the y-axis. When the point is translated 4 units to the left, its x-coordinate is reduced by 4: x ⇒ x-4.

The y-coordinate of a point is the measure of the vertical distance a point is above the x-axis. When the point is translated 2 units up, its y-coordinate is increased by 2: y ⇒ y+2.

__

The translation 4 units left and 2 units up can be summarized by ...

  (x, y) ⇒ (x -4, y +2)

Then the translated vertices are ...

  Q(1, 3) ⇒ Q'(1 -4, 3 +2) = Q'(-3, 5)

  R(5, 1) ⇒ R'(5 -4, 1 +2) = R'(1, 3) . . . . . . . matches choice C

  S(3, 5) ⇒ S'(3 -4, 5 +2) = S'(-1, 7)

Of the points listed, the point (1, 3) matches a translated vertex.

(1/2) *  14 * 9 = 63

Answer: 63 in²

Step-by-step explanation:

      The problem gives us the formula to use. We will simplify plug in the correct values and solve.

b = base

h = height

[tex]\displaystyle \frac{b*h}{2}[/tex]

[tex]\displaystyle \frac{14*9}{2}[/tex]

z + 38° = 180°

(L.P)

z = 142°

y = 32° (alternative angle of angle FCA)

x = 142° (alternative angle of angle z)

x + 65 = 180

(l.p)

x = 180 - 65

x = 115°

y = x (alternative angle of x)

y = 115°

z = y (V.O.A)

z = 115°

Answer:

Step-by-step explanation:

2)  Linear pair: Two angles are called linear when they are adjacent angles and the non common arms form a straight line. They add uo to 180

 z + 32 = 180     {linear pair}

         z = 180 - 32

When parellel lines are cut by a transversal alternate interior angles are equal.

          y = 32°        {Alternate interior angles}

           x = z           {Alternate interior anlges}

           x = 148°

3) x +65 = 180  {linear pair}

          x = 180 - 65

     y = x          {Alternate interior angles}

z = y      {Verically opposite angles}

z = 115°

Step-by-step explanation:

old population- 120,000

new population- 133,200

increase - 133200-120000

=13200

percentage increase:

(13200*100)/120000

=11%

Answer:

B

Step-by-step explanation:

a+2d=0

a+3d=6

d=6

a=6-3(6)

a=6-18

a= -12

a+(n-1)d

= -12+(n-1)6

= -12+6n-6

= -18+6n

Answer:

Radius is half the diamiter of a circle, basically the whole length from one point of the circle to the middle.

Answer:

Radius is how far the middle of the circle is from the edge of the circle.  For example, we know that a circle has a middle point and we know that we have a line around it in the shape of a circle.  The radius would be the distance from the middle point to the outer line of the circle.

The probability of both being a waiter is,

P(Both Waiter) = (3/9)×(4/12) = 1/9

The probability of both being chefs,

P(Both Chef) = (2/9)×(4/12) = 2/27

The probability of both being a Dishwashers,

P(Both Dishwasher) = (4/9)×(4/12) = 4/27

Thus, the probability that the woman shared the same profession is,

Probability = P(Both Waiter) + P(Both Chef) + P(Both Dishwasher) = 0.33

Hence, the probability that the woman shared the same profession is 0.334.

The perimeter of the larger hexagon, where the smaller hexagon is increased by a factor of 5:7 is: 84 units.

If two shapes are similar, the ratio of their perimeter equals the ratio of their respective sides.

Since the smaller hexagon is increased by a factor of 5:7, therefore:

Length of the larger hexagon = 7/5 × 10 = 14 units.

Perimeter of the larger hexagon = 6(14) = 84 units.

Two possible lengths of ribbon (In inches) are 25 and 133  3/4

Step-by-step explanation

Okay, so- First, You need to find out how much ribbon is there before the two additional ones are added. Like this:

12 + 14  2/4 + 14  3/4 = 41  1/4

Next, subtract that amount from 200 to get the number of inches of ribbon that are needed to get 200 inches of ribbon. Like this:

(I changed it to a decimal to make it easier, so don't mind that)

200 - 41.25 = 158.75

So, 158.75 inches of ribbon are needed to get 200 inches. You can subtract any number less than 158.75 from that to get two seperate ribbon measurements.

(This might sound confusing so here)

For example:

158.75 - 25 = 133.75 (The bolded numbers are the two measurements)

158.75 - 65 = 93.75

So, Two possible lengths (in inches) of ribbon that kelly could have added are "25" and "133.75 "

Two possible lengths (in inches) of ribbon that kelly could have added are also "65" and "93.75"

The area of the equilateral triangle with the given perimeter is 24.2cm².

Hence, option D)24.2cm² is the correct answer.

This question is incomplete, the complete question is:

An equilateral triangle has an apothem measuring 2.16 cm and a perimeter of 22.45 cm. What is the area of the equilateral triangle, rounded to the nearest tenth?

A triangle is simply a two-dimensional polygon with 3 sides and 3 interior angles.

An equilateral triangle is a triangle with all its three sides having the same length

The area of an equilateral triangle is expressed as;

A = ((√3)/4)a²

Where a is the length of the side

Perimeter of an equilateral triangle is expressed as;

P = 3a

Where a is the length of the side

Given that the perimeter of the equilateral triangle is 22.45 cm, the sides of the triangle will be;

P = 3a

22.45cm = 3a

a = 22.45cm / 3

a = 7.48cm

Now, the area of the equilateral triangle will be;

A = ((√3)/4)a²

A = ((√3)/4) × (7.48cm)²

A = 0.433 × 55.9504cm²

A = 24.2cm²

The area of the equilateral triangle with the given perimeter is 24.2cm².

Hence, option D)24.2cm² is the correct answer.

Answer:

1: 81 is the overall angle, so to find the 2nd angle that makes up the overall angle, just subtract the 1st angle from the overall angle. it would be 81 - 44 = 37. so your answer is 37°.

2: this one is solved the same as number 1, just different numbers. it would be 98 - 59 = 39. your answer is 39°.

3. we know this is angle is a right angle because of the square indicating it. a right angle is 90°, so we would take 90 - 63 = 27. so your answer is 27°.
