Heres 1. Use the table and the graph to answer the questions.
(a) What is the rate of change for each function? Show your work.
(b) Which function has the greater rate of change?
can you help me do these things
heres 1. Use the table and the graph to answer - 1

Answers

Answer 1
Answer: For the rate of change of Function 1, it is 2 because when I did delta y over delta x (3/-1)-(5/-2) i got negative 2 over negative 1. Two negatives equal a positive. For the rate of change of Function 2, it is 4. I picked two points that can even meet. Then I use the formula of rise over run to comes out as 4/1 simplified to 4. So Function 2 has the greater rate of change.
Answer 2
Answer:

Answer:

The rate of change of first function is -2.

The rate of change of second function is 4.

Function 2 has greater rate of change.

Step-by-step explanation:

If a line passes through two points (x_1,y_1) and (x_2,y_2), then the formula for rate of change is

m=(y_2-y_1)/(x_2-x_1)

From the table and graph consider any two points to find the rate of change of each function.

From the table, let as consider two point (-1,3) and (-2,5). The rate of change of first function is

m=(5-3)/(-2-(-1))

m=(2)/(-2+1)

m=-2

The rate of change of first function is -2.

From the graph, let as consider two point (-1,0) and (0,4). The rate of change of second function is

m=(4-0)/(0-(-1))

m=(4)/(1)

m=4

The rate of change of second function is 4.

Since -2<4, therefore function 2 has greater rate of change.

Harvey bought a. Frame in which he put his family picture in what is the area of the frame not covered by the picture

Answers

Answer:

Area of the frame not covered with photo is equal to 129 square inches

Step-by-step explanation:

Given: Image of a frame

To find: Area of the frame not covered by the picture

Solution:

Area of rectangle = length of the rectangle × breadth of rectangle

Area of the frame = length of frame × breadth of frame = 23 × 15 = 345 square inches

Area of the frame covered with photo = 18 × 12 = 216 square inches

Area of the frame not covered with photo = Area of the frame - Area of the frame covered with photo = 345 - 216 = 129 square inches
