Wittaler [7]3 years ago
7 0

Step-by-step explanation:

angle ADC = angle ABC / 2

= 135/2 = 67.5°

AC = 2r * sin (62.5)

AC = 1.84r

r is the radius of circle

Do the values in the table represent a proportional relationship?
Ostrovityanka [42]

We can conclude that: All of the y-values in the table of values are not a constant multiple of the corresponding x-values, so the relationship is not proportional.

<h3>How tp Determine if a Table Represents a Proportional Relationship?</h3>

A given table of values that represents a proportional relationship will have all of its y-values as a constant multiple (k) of its corresponding x-values. Thus, the constant of proportionality, k, = y/x.

Given the table of values above, find the constant multiple, k, between each pair of values:

k = 2.4/2 = 1.2, [for (2, 2.4)]

k = 5.6/4 = 1.4, [for (4, 5.6)]

k = 9.6/6 = 1.6, [for (6, 9.6)]

k = 14.4/8 = 1.8, [for (8, 14.4)]

Thus, we can see that the pair of values in the given table of values each has different ratio of y to x.

There is no constant multiple or constant of proportionality. This means, the table of values given does not represent a proportional relationship.

In conclusion, we can state that: All of the y-values in the table of values are not a constant multiple of the corresponding x-values, so the relationship is not proportional.

Two points are 10 units apart on the coordinate plane. If
galina1969 [7]

Answer:

The vertical distance the ant have to walk is 8 units

Step-by-step explanation:

∵ The ant must be walk vertically and horizontally

∴ The distance from start point to end point will be as

   a hypotenuse of a right angle triangle

∵ The ant would have to walk 6 units horizontally that

   means one side of the right angle is 6 units

∵ The two points are apart by 10 units that means

   the length of the hypotenuse is 10 units

∴ The vertical distance the ant would have to walk is

   the length of the second side of the right angle

* By using Pythagoras Theorem:

∵ (hypotenuse)² = (horizontal leg)² + (vertical leg)²

∴ 10² = 6² + (vertical leg)²

∵ (vertical leg)² = 100 - 36 = 64

∴ Vertical leg  = √64 = 8 units

∴ The vertical distance the ant have to walk is 8 units

a school science fair has 24 projects about Earth Science in 36 projects about physical science the projects will be displayed i
Dafna1 [17]
24 =
{2}^{3}  \times 3
36 =
{2}^{2}  \times  {3}^{2}
The greatest common factor of 24 and 36 is
{2}^{2}  \times 3
Thus 12 is the greatest number of projects that can be in a row.
