Draw a line segment between each vertex of ABCD and the corresponding vertex of AEFBEFCEFDEF.
There are four line segments in all. Then move polygon ABCD around the coordinate plane. What do
you observe about the angle formed between the line segments you drew and the line of reflection,
EF? Use the tools available in GeoGebra to confirm your hypothesis.
Answer:
Each line segment joining a vertex of ABCD to the corresponding vertex in the image is perpendicular to the line of reflection, EF. That is, the lines intersect at a 90 degree angle.

Leticia invests $200 at 5% interest. If y represents the amount of money after x time periods, which describes the graph of the exponential function relating time and money? The initial value of the graph is 200. The graph increases by a factor of 1.05 per 1 unit increase in time. The initial value of the graph is 200. The graph increases by a factor of 5 per 1 unit increase in time. The initial value of the graph is 500. The graph increases by a factor of 2 per 1 unit increase in time. The initial value of the graph is 500. The graph increases by a factor of 1.02 per 1 unit increase in time.
Answer:
A. The initial value of the graph is 200. The graph increases by a factor of 1.05 per 1 unit increase in time.
Hope this helps!
Step-by-step explanation:
The initial value of the graph is 200. The graph increases by a factor of 1.05 per 1 unit increase in time the graph of the exponential function relate to time and money.
Given that,
Leticia invests $200 at 5% interest.
If y represents the amount of money after x time periods.
We have to determine,
Which describes the graph of the exponential function relating time and money?
According to the question,
The graph represents the exponential function relating time and money.
Where y represents the amount of money after x time periods.
After 1 period the amount of money is,
[tex]\rm f(x) = 200 + 200\left(\dfrac{5}{100}\right)\\\\f(x) = 200(1+0.5)\\\\f(x)= 200(1.5)\\\\[/tex]
After 2 periods the amount is,
[tex]\rm f(x) = 200(1.5) \times (1.5)\\\\f(x) = 200. (1.5)^2[/tex]
After 3 periods the amount is,
[tex]\rm f(x) = 200(1.5)^2 \times (1.5)\\\\f(x) = 200. (1.5)^3[/tex]
Therefore,
The amount after x period is,
[tex]\rm f(x) = 200(1.5)^x[/tex]
The initial value is when x = 0,
[tex]\rm y = 200 (1.05)^0 \\\\y = 200\times 1\\\\y = 200[/tex]
And the increasing factor is 1.05 because any value is the previous one times 1.05.
Hence, The initial value of the graph is 200. The graph increases by a factor of 1.05 per 1 unit increase in time the graph of the exponential function relate to time and money.

What do you think is going to be the most challenging part of Alg.1 and why?
Answer:
I think Factoring is going to be the most challenging part of Alg.1 because it seems like there are a lot of steps before finding the answers.
Explanation:
When I took algebra I, the most difficult part for me was inequalities.
I had been used to linear equations and even quadratic equations, where the operative rule is "keep the equal sign sacred" (whatever you do to one side must also be done to the other side). Once I figured out that multiplying or dividing inequalities by a negative number reverses the comparison, I was good to go.
__
These days, algebra I also includes a good dose of statistics. That seems to trip up a number of people, including me. The main thing, I think, is to stay clear on the definitions, and whether you're talking about a population or a sample. A lot of the math is easily handled by a graphing calculator or spreadsheet, so familiarity with the use of those is a great bonus (almost required).
__
You will be better equipped to go into algebra I if you have memorized multiplication tables, rules of divisibility, some mental math procedures, and squares and cubes of small integers (square ≤ 20^2, cubes ≤ 10^3). This will help immensely when it comes to factoring. Similarly, you need to be familiar with arithmetic involving decimals, fractions, and mixed numbers. Numbers in one form should offer you no more challenge than numbers in any other form.
__
A big challenge for many people is the fact that math builds on previous learning. If you don't learn the early stuff well, and practice it a lot, then you will find you have difficulty drawing on that knowledge to make the later stuff easier. It's NOT a "test and forget" sort of deal. It's a "remember this forever" sort of deal.
The 5 staring members of the basketball team are lining up for a picture.How many different ways can the players be lined up for the picture?
Answer:
120 different waysStep-by-step explanation:
If 5 staring members of the basketball team are lining up for a picture, the number of different ways the players can be lined up is expressed as 5!.
5! = 5*4*3*2*1
5! = 20 * 6
5! = 120
Hence the number of different ways that the players can be lined up for the picture is 120 different ways

Jamal borrowed 4000 to buy a used car he borrowed some of the money from a bank that charged 9.2% simple interest and the rest from a friend who charged 12% simple interest. If the total interest for a one year loan was 424.00 how much did jamal borrow at each rate
Answer:
2000 ; 2000
Step-by-step explanation:
Given the following :
Total amount borrowed = 4000
Total interést paid = 424
Simple interést = (principal * rate * time)
Rate 1 = 9.2% = 0.092
Rate 2 = 12% = 0.12
Let amount borrowed at 9.2% = x
Amount borrowed at 12% = y
x + y = 4000 - - - - (1)
x * 0.092 + y * 0.12 = 424
0.092x + 0.12y = 424 - - - - (2)
from (1):
x = 4000 - y
0.092(4000 - y) + 0.12y = 424
368 - 0.092y + 0.12y = 424
368 + 0.028y = 424
0.028y = 424 - 368
0.028y = 56
y = 56/0.028
y = 2000
x + y = 4000
x = 4000 - 2000
x = 2000

The statement “1cm represents 2m” is the scale of the drawing. It can also be expressed as “1cm to 2m” or “1cm for every 2m.” What do you think the scale tells us?
Answer:
A scale is a way to resize drawings or figures to make them fit into a particular size.
Step-by-step explanation:
In 2D drawing or diagrams, a scale factor greater than 1 enlarges the object, while a scale factor between 0 and 1 shrinks the objects, also using a scale factor of 1 changes nothing or leaves the drawing the way it is.
Furthermore, scales are represented in ratio form 1:2, telling us that say 1cm in the virtual environment or paper represents 2km in reality
