The steps for using a compass and straightedge to construct the bisector will be:

1. Place the point of the compass on point G and draw an arc that intersects the sides of ∠G.

2.Label the points of intersection as points H and J.

3. Place the point of the compass on point H and draw an arc in the interior of the angle.

4. Without changing the opening of the compass, place the point of the compass on point J and draw another arc in the interior of the angle.

5.Label the intersection of the arcs in the interior of the angle as point K.

6. Use the straightedge to draw GK.

Bisection in geometry is the division of something into two equal or congruent portions, usually by a line, which is then known as a bisector. The segment bisector and the angle bisector are the most commonly used forms of bisectors.

To bisect anything implies to divide it into two equal sections. A bisector is a line that divides anything into two equal pieces. Bisectors include segment bisectors, angle bisectors, and shape bisectors. A segment bisector is a line that runs across the center of a particular segment.

The area of Rachel's bedroom is 72 square feet. The bedroom area that is eight times of Rachel's closet. The length of the closet if it is 3 feet wide is 3.

Given that,

The area of Rachel's bedroom is 72 square feet. The bedroom has an area that is eight times that of Rachel's closet.

We have to find what is the length of the closet if it is 3 feet wide.

First we divide the area of Rachel's bedroom is 72 square feet and eight times that of Rachel's closet.

72/8=9

Now, we multiply 3 and the length as l is equal to 9 feet wide

3×l=9

l=9/3

l=3

The food is available for all snow geese for 11.5 days before the research and rescue center runs out.

According to the question,

We have the following details:

Number of snow geese in the research and rescue center = 9

Number of ounces of seeds eaten by each goose = 16 ounces

So, number of ounces of seeds eaten by 9 snow geese = (16*9) ounces

Number of ounces of seeds eaten by 9 snow geese = 144 ounces

Now, there are 1,656 ounces of seeds.

So, the number of days before the center runs out of the food = Total number of ounces of seeds/Number of ounces of seeds eaten by 9 snow geese

Number of days before the center runs out of the food = 1656/144

Number of days before the center runs out of the food = 11.5 days

Hence, the number of days for which food is available for all snow geese before the center runs out is 11.5 days.

Answer: 1.001 x 10^3

Step-by-step explanation:

    Lines that are parallel to one another on a plane do not intersect or meet at any point. They are always equidistant from one another and parallel. Non-intersecting lines are parallel lines. Parallel lines can also be said to meet at infinity.

The slope of parallel lines is the same. By converting the line 2x -4y = 8 to slope intercept form, first determine its slope.

4y = 8-2x y = 1/2x - 4 2x + 4y = 8

Here, the slope is 1/4

Fill in the point slope form with (-2, -4) and m = 1/4 After that, simplify to obtain the standard form and slope intercept form.

The slope intercept form is y = 1/4x + 6, while the point slope form is y - (-4) = 1/4(x+4).

Now, by rearranging the terms into the formula Ax + By = C, the standard form may be discovered.

6 becomes -1/4x + y = 6 when y= 1/4x + 6. Since fractions for A or B cannot be expressed in standard form, the equation is multiplied by 4 to get x + 4 y = 24.

The linear equation in the slope-point form is:

(y - 4) = 2*(x - 3)

For a line with a slope M that passes through a point (a, b), the point-slope form is:

(y - b) = M*(x - a)

And if the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope is:

M = (y₂ - y₁)/(x₂ - x₁)

In this case the line passes through (3,4) and (6,10) is:

M = (10 - 4)/(6 - 3) = 6/3 = 2

And using the point (3, 4), we can write:

(y - 4) = 2*(x - 3)

Angle x =  90°, y = 5 and angle z =  75°.

Here, we are given two figures as shown in the figure above.

Figure 1 is a kite. The diagonals of a kite bisect each other at right angles.

Thus, here, the angle made by the intersection point of diagonals BD and AC will be 90°.

Thus, angle x =  90°.

Now, figure 2 is an isosceles trapezoid. In an isosceles trapezoid the two non-parallel sides are equal and the angles opposite to them are also equal.

Thus, here the two non-parallel sides- FE and GH will be equal.

⇒ y = 5

Further, the angle opposite to GH is 75° and that opposite to FE is z.

Thus, z =  75°

If Cora uses the 15% off coupon first then the new total is $92.65. After using the $10 off coupon, the total is $82.65.

If Cora uses the $10 off coupon first, the total goes to $99. Taking 15% off of $99 leaves her with a total of $84.15.

2. P = 4500(1.04)^t is exponential growth.

3.A = 7000(1.0575)^t is exponential growth.

4.P = 50(1/2)^t is exponential decay.

5.P = 45(2)^t is exponential growth.

6.A = 9000(0.9)^t is exponential decay.

Given that,

We have to find which equation is exponential growth and exponential decay.

Knowing that an exponential function takes the form where a represents the function's y=a.bˣ initial value a and b represents its exponential growth or exponential decay, B should be more than 1 for exponential growth and less than 1 for exponential decay.

b>1= exponential growth.

b<1= exponential decay.

Let's now examine each equation in turn to see which one represents exponential growth and which exponential decay.

1. [tex]V=18000(0.78)^{t}[/tex]

The initial values a and b in this option are 18000 and 0.78 respectively. Since 0.78 is smaller than 1, this equation describes exponential decay.

2.[tex]P=44500(1.04)^{t}[/tex]

Since 1.04 is obviously more than 1, and we can see that a = 4,500 and b equals 1, we may conclude that this equation represents exponential growth.

3.[tex]A=7000(1.0575)^{t}[/tex]

Since 1.0575 is clearly more than 1 and since a equals 7000 and b equals 1.0575, this equation clearly represents exponential growth.

4.[tex]P=50(1/2)^{t}[/tex]

Given that a = 50 and b equals 1, and that 0.5 is unmistakably less than 1, it is evident that this equation describes exponential decay.

5. [tex]P=45(2)^{t}[/tex]

Since a and b are equal to 45 and 2, respectively, and 2 is obviously greater than 1, this equation represents exponential growth.

6.[tex]A=9000(0.9)^{t}[/tex]

Since 0.9 is obviously less than 1 and that an equals 9000 and b equals 0.9, this equation represents exponential decay.

What is ratio of triangle ?

 The definition of the tangent (tan) of the angle is the ratio of the opposing to the neighbouring in any right triangle. The tangent's value for the red triangle is given by: tan(c) = 1 / 2 =.5. We maintain the same angle c for the blue triangle, but we have doubled the sizes of the adjacent and opposite sides.

It always helps to draw a diagram and find the right triangle.  

In this case, the triangle has the loading dock as one leg, the ramp as the hypotenuse, and the distance of the ramp from the loading dock as the other leg.

Call that distance x.  Use the tangent of 25° to find x.

=> tan(25°) = [tex]\frac{opposite }{adjacent}[/tex]

=> tan(25°) = [tex]\frac{5}{x}[/tex]

x int = (5,0)

y int = (0,-2)

Step-by-step explanation:

To solve for x int set y as zero

4x - 10(0) = 20

4x - 0 = 20

4x = 20 divide by 4 to get x alone

x = 5

To solve for y set x as zero

0 - 10y = 20

- 10y = 20 divide by -10 to get y alone

yes, its parallel

Step-by-step explanation:

Choices:

a. 3x+y=18

b. 3x+y=-8

c. 3x+y=8

d. 3x+y=-10

1. if we plug in (6, -10) to 3x+y=8 we get:

3(6) + (-10) = 8

18 - 10 = 8

8 = 8, this is true

2. if we simplify 6x+2y=12 we get:

2y = -6x + 12

y = -3x + 6

if we simplify 3x+y = 8 we get

y = -3x + 8
