Answer 1

Answer: The center is 0,4

Step-by-step explanation:

Use this form to determine the center and radius of the circle:

(

x-h)^2+(y-k)^2=r^2

Match the values in this circle to those of the standard form. The variable  r  represents the radius of the circle,  h  represents the x-offset from the origin, and  k  represents the y-offset from origin:

r=8

h=0

k=4

The center of the cirle is found at (h,k): (0,4)

The radius is 8

What is the surface area of the square pyramid?
340 square feet
420 square feet
480 square feet
580 square feet

Answers

Square Pyramid

Hence , the surface area of the square pyramid is 340 square feet

Step-by-step explanation:

The square pyramid has a square base

Given that the base side is 10 ft and the slant height of the pyramid is 12 ft.

The surface area of a square pyramid is SA, then

SA = Area of the base + [tex]\frac{1}{2}[/tex] × P × Sh

where P is the perimeter of the base and Sh is the slant height of the pyramid

P = 4 × 10

SA = [tex]10^{2} + \frac{1}{2}[/tex]× 40 × 12

SA = 100 + 240

SA= 340 square feet

Hence , the surface area of the square pyramid is 340 square feet

Jamie paid the rent well past the due date for the months of April, May and June. As a result, he had been charged a total of $75 as late fee. How much did he pay as late fee per month?

Answers

He paid $225 as a late fee per month
Final answer:

Jamie paid $25 as a late fee per month. Hence, the final answer is $25 per month.

Explanation:

To find out how much Jamie paid as a late fee per month, we first need to determine how many months he was charged for and then divide the total late fee by that number.

In this case, he was charged for the three months of April, May, and June, so there were 3 months.

The total late fee was $75, so to find out how much he paid per month, we divide the total late fee by the number of months: $75 / 3 = $25 per month.

The surface area of a triangular prism is 78 square inches. What is the surface area of a similar prism that is three times as large?

Answers

Answer:

234 inches

Step-by-step explanation:

The prism is 3× larger so you would multiply 78 by 3

Final answer:

To find the surface area of a similar prism three times as large, you need to square the scaling factor and multiply it by the original surface area.

Explanation:

The surface area of a triangular prism is 78 square inches. Given that the area scales in proportion to the square of the linear dimensions, if a similar prism is three times as large, the surface area of the larger prism would be 3² = 9 times the original surface area. Therefore, the surface area of the similar prism that is three times as large would be 78 square inches x 9 = 702 square inches.

A scientist studies a pod of humpback whales to determine the
migration of humpback whales. What is the population?

A. all whales
B. a pod of humpback whales
C. killer whales
D. all humpback whales

Answers

Answer is D !! Hope this helpsss

Final answer:

In biology, the population refers to all individuals of a species in an area. For the humpback whale study, the population is the specific pod of whales being studied, not all whales or humpback whales in general. This aligns with population ecology principles.

Explanation:

The population in a biology context refers to all the members of a single species living in a particular area. In the given scenario where a scientist studies a pod of humpback whales to determine the migration of humpback whales, the correct answer would be B. a pod of humpback whales. This is because the scientist is studying a specific group of humpback whales, which constitutes a population within the larger population ecology context of all humpback whales.

Population ecology is a field that focuses on the number of individuals of one species in an area and how and why that number changes over time. It helps in understanding different aspects of species like their migration patterns, social structures, and interaction with the environment. A pod of humpback whales would be considered a distinct population if they are living together in the same space and are interbreeding, as per the definition of a population in this biological field.

d.
32; yes


Please select the best answer from the choices provided

A
B
C
D

Answers

The inner product of vectors (8,4) and (2,4) is 32, and since the dot product is not zero, the vectors are not perpendicular.

The inner product (also known as the dot product) of two vectors can be calculated by multiplying the corresponding components of the vectors and then summing those products. For the vectors (8,4) and (2,4), the inner product is calculated as (8 × 2) + (4 × 4), which equals 16 + 16, and thus the inner product is 32.

To determine if the vectors are perpendicular, we need to check if their dot product is zero. In this case, since the dot product is 32, not zero, the vectors are not perpendicular to each other.

Therefore, the correct answer is C: 32; no.

Add x to both sides:

x=8

Solving for Y:

Bivariate data is data for two, usually related, variables. Each value of one variable is paired with a value of the other, for example, the height and shoe size of each student in a high school class. Bivariate data can be plotted on a coordinate plane called a scatter plot. A scatter plot’s x-axis represents one variable, and its y-axis represents the other. By plotting each data pair on a scatter plot, we can visualize the relationship between variables. Scatter plots help us understand whether or not something like height and shoe size are related. Scatter plots also help us identify outliers and clustering in a set of bivariate data. Outliers are values that are much larger or smaller than most other values in a data set. On a scatter plot, outliers are easy to spot since they appear well above or below most other plotted points. Clustering becomes apparent when points are bunched close together. This tells us something about how common a particular range of values is.

Final answer:

Bivariate data consists of pairs of related variables and is visualized using a scatter plot. Scatter plots help identify relationships between variables, as well as outliers and clusters within the data.

Explanation:

Bivariate data refers to data that consists of pairs of variables, for example, the height and shoe size of students. Each pair of data is connected, which represents a specific point in the data set. When presented on a scatter plot, bivariate data gives a visual representation of the relationship between these two variables. The x-axis of a scatter plot indicates one variable and the y-axis represents the other.

Scatter plots give us the ability to identify both the existence of relationships between variables and the presence of outliers, which are values significantly larger or smaller than the other values in the data set. These outliers are easy to spot on a scatter plot as they are often far removed from the other plotted points. Scatter plots also help to identify clusters, which is when data points are grouped closely together, indicating a common range of values for the variables.
