What is displacement?
Displacement is defined as a change in an object's position. An object's displacement is defined as how far it has moved from its starting point. The dependent variable in the displacement time graph is displacement, which is represented on the y-axis, and the independent variable is time, which is represented on the x-axis. Position-time graphs are another name for displacement time graphs.
The displacement curve is given for 0 ≤ t ≤ 18.
We need to find the total distance of the curve, it will be the positive sum of all displacements.
So, total distance = (7-0) + (3-0) + (2+3) + (2+4) + (7-4)
= 7 + 3 + 5 + 6 + 3
= 24
Hence, the total distance is 24 units.

Fill in the blank with an appropriate word, phrase, or symbol(s). The number of regions created when constructing a Venn diagram with three overlapping sets is The number of regions created when constructing a Venn diagram with three overlapping sets is 8 3 6
The number of regions created when constructing a Venn diagram with three overlapping sets is 8.
In a Venn diagram, each set is represented by a circle, and the overlapping regions represent the elements that belong to multiple sets.
When three sets overlap, there are different combinations of elements that can be present in each region.
For three sets, the number of regions can be calculated using the formula:
Number of Regions = 2^(Number of Sets)
In this case, since we have three sets, the formula becomes:
Number of Regions = 2^3 = 8
So, when constructing a Venn diagram with three overlapping sets, there will be a total of 8 regions formed.
Each region represents a unique combination of elements belonging to different sets.
These regions help visualize the relationships and intersections between the sets, providing a graphical representation of set theory concepts and aiding in analyzing data that falls into multiple categories.
Therefore, the correct answer is 8.

Given m//n find the value of x and y (9x-1)° (y-20)° (5x-15)°
Looking at the given diagram,
angle 9x - 1 and angle y - 20 are linear pairs. they lie on a straight line. The sum of the angles on a straight line is 180 degrees. It means that
9x - 1 + y - 20 = 180
y = 180 + 1 + 20 - 9x
y = 201 - 9x equation 1
Also, angle 5x - 15 and angle y - 20 are vertically opposite angles. Vertically opposite angles are equal. It means that
5x - 15 = y - 20 equation 2
Substituting equation 1 into equation 2, it becomes
5x - 15 = 201 - 9x - 20
Collecting like terms, it becomes
5x + 9x = 201 - 20 + 15
14x = 196
x = 196/14
x = 14
y = 201 - 9x = 201 - 9 * 14
y = 201 - 126
y = 75+

The idea of Manifest Destiny arose in response to the prospect of U.S. annexation of Texas and to a dispute with Britain over the Oregon Country, which became part of the union.
Answer:
D. Annexation of Texas.
Step-by-step explanation:
Remember from the previous answer, the Manifest Destiny was the "justifiable source" in the expansion of the US westward. What is not known as Texas, was part of the Manifest Destiny. During this time, the Mexican Government allowed for US citizens to populate the lands that stretch from Texas to parts of California. However, it is important to note that they did not allow slavery, which is a large factor in the Texas Independence. With the independence of Texas, and the annexation of Texas from the Republic of Texas to the state of Texas, the US added a large sizable chunk to it's borders, further expanding the US in the southwest sector.

A custom made football field is 200 yards long and 80 yards wide. What is the area of this field in square meters (m^2)? 1 yd 3 ft - 1 m = 3.28 ft 13385 O11343 8922 O 9011
Given : A custom made football field is 200 yards long and 80 yards wide.
To find the area of the football field in square meters, we need to convert the measurements from yards to meters and then calculate the area.
Length of the field = 200 yards Width of the field = 80 yards
1 yard is equal to 0.9144 meters. So, we can convert the measurements as follows:
Length in meters = 200 yards * 0.9144 meters/yard Width in meters = 80 yards * 0.9144 meters/yard
Now, we can calculate the area of the field in square meters:
Area in square meters = Length in meters * Width in meters
Substituting the values:
Area = (200 yards * 0.9144 meters/yard) * (80 yards * 0.9144 meters/yard)
Simplifying the expression:
Area = (200 * 0.9144 * 80 * 0.9144) square meters
Calculating the result:
Area ≈ 11839.68 square meters
Therefore, the area of the custom made football field is 200 yards long and 80 yards wide. is approximately 11839.68 square meters.

Options are listed at the bottom
Looking at the triangles, the information needed to prove that ABC∼△DEF is AC = 10
What are similar triangles?This is a term used in geometry to mean that the respective sides of the triangles are proportional and the corresponding angles of the triangles are congruent
Hence assuming the corresponding angles of the triangle are congruent then the side should be in proportions
Examining the figure shows that pair of equivalent sides are
AB and DE, BC and FE, then AC and DF
The solution is worked out using sides BC and FE, then AC and DF
BC / AC = FE / DF
8 / AC = 16 / 20
reducing the fraction 16/20 gives
8 / AC = 8 / 10

Independent samples t-tests are limited to situations in which there are only treatments being compared. This chapter looks at tests where or more means are involved.
ANOVA is used to determine whether differences between groups are due to chance or whether they are genuine and can be attributed to the treatments or variables being investigated.
Independent samples t-tests are limited to situations in which there are only treatments being compared. However, when we have two or more means involved, we use one-way analysis of variance (ANOVA) or factorial ANOVA to compare groups and establish whether there are significant differences between them.
The fundamental principle of ANOVA is to compare the variance within groups to the variance between groups, with the F-test being used to determine the significance of the differences. While the independent samples t-test is employed to compare the means of two independent samples, ANOVA, on the other hand, is utilized to determine if there is a difference in the mean values of two or more groups.
ANOVA partitions the total variation among the group's observations into two categories, one due to differences between the means of the groups and the other due to variability within each group.
In conclusion, ANOVA is used to determine whether differences between groups are due to chance or whether they are genuine and can be attributed to the treatments or variables being investigated.
