2. When Deema begins her drive, she is 400 mi from home. She drives at an average rate of 50 mph until she gets

home. Draw a graph to represent this situation?

Answers

Answer: I can give coordinates (0,400) (1,350) (2,300) (3,250) (4,200) (5,150) (6,100) (7,50) (8,0)

Step-by-step explanation:

Deema starts at 400 which is y-intercept and goes down on a slope of -50 cause we are decreasing 50 mi for every hour she drives.

Hope this helped :) !!!!!!!

The coordinates of the graph representing the given situation are listed below

A (0 ,400)

B ( 1 ,350 )

C (2,300)

D(3,250)

E(4, 200)

F(5, 150)

G(6, 100)

H(7, 50)

I (8, 0)

The graph attached shows the nature of the graph.

Total distance traveled by Deema = 400 miles

The average speed of Deema = 50 mph

In each 1 hour, 50 miles of distance will be covered

So by the rate of 50 miles per hour the coordinates in this situation are given as follows

Time (X axis) Distance (Y axis)

0 400

1 350

2 300

3 250

4 200

5 150

6 100

7 50

8 0

The coordinates of the graph are listed above and the nature of graph is shown in the figure attached in the solution.

The graph of this situation has a constant negative slope.

Consider the sequence 100, 95, 90, 85, 80, 75 ...
What is the value of f(8)?

Answers

Answer:

f(8) = 65

Step-by-step explanation:

Find a pattern in the sequence. It might be an arithmetic sequence (always adds or subtract by a certain number), or a geometric sequence (always multiplies or divides by a certain number).

To find a pattern in this decreasing sequence, we find either the common difference or the common divisor of each pair of consecutive numbers.

• 100 - 95 = 5

• 95 - 90 = 5

• 90 - 85 = 5

• 85 - 80 = 5

• 80 - 75 = 5

Now, we know that this is an arithmetic sequence, and the common difference is 5.

To calculate f(8), we find the 8th term in the sequence. We can do that by counting the terms in the sequence and using the common difference, 5, that we found, to continue the sequence.

• f(1) = 100

• f(2) = 95

• f(3) = 90

......

• f(7) = 70

• f(8) = 65

This is a proof question. Please show step by step.

Answers

Step-by-step explanation:

= (5⁹⁹ * 2⁹⁸) * (5⁷² * 4³⁸)

= 2⁹⁸ * 2⁷⁶ * 5⁹⁹ * 5⁷²

= 2¹⁷⁴ * 5¹⁷¹

= 2³ * (2¹⁷¹ * 5¹⁷¹).

The 2¹⁷¹ * 5¹⁷¹ will give 171 ending zeroes as 2 * 5 = 10.

And there is a 8 infront as 2³ = 8.

Hence altogether there are 171 + 1 = 172 digits.

Does the point (-3,-1) lie on the line with the equation y = 10 - 3x ? Be sure to show your work.

Answers

Replace x in the equation with the x value from the point and solve. If the equation equals the y value from the point the point lies in the line, if it doesn’t equal the y value then it doesn’t lie on the line.

Y = 10 -3(-3) = 10 + 9 = 19

19 doesn’t equal -1 so the point does not lie on the line.
