Which sequence is modeled by the graph below?

Maru [420]

We have

a2 = 4

a3 = 2

a4 = 1

calculate the difference

a3 - a2 = -2

a4 - a3 = -1

The differences are not equal---------- >the sequence is not arithmetic.

Getting the ratio:

a3/a2 = 0.5

a4/a3 = 0.5

The common ratio is 0.5. Using the general form for a geometric series:

an = a1 r^(n-1)

for n = 2---------------- > a2=4

4 = a1 (0.5)^(2-1)

a1 = 8

therefore

an = 8 (1/2)^(n-1)

the answer is an = 8 (1/2)^(n-1)

the answer is none of those indicated in the question

Ben wants to get a 94 in math class. His grade will be the average of two test scores. He scored an 89 on the first test. What g

In-s [12.5K]

Answer:

Ben needs to get a 99% on his second test

Step-by-step explanation:

The average is the sum of both test scores, divided by the total number of test scores (2).

Let x by the grade Ben must receive on his second test.

(89 + x)/2 = 94

Multiply by 2 on both sides

89 + x = 188

Subtract 89 on both sides

x = 99

Check work:

(89 + 99)/2 = 188/2 = 99

80 points! Look at pic attached. I will mark brainiest if you explain your reasoning good. Random answers will be reported.

gregori [183]

Answer: No, your friend is not correct. You cannot use a similarity transformation to turn a square into a rectangle. Here's why:

1) If you used a similarity transformation, the size and position of the shape would change, but the shape itself remains the same.

2) Squares and rectangles are NOT similar.* Referring to the first point I listed, if the shapes are not similar, then a similarity transformation cannot be used to turn one shape into another.

<em>*Similar means that the edges are proportional to one another, such as a square with sides of 4 meters vs a square with sides of 2 meters: the sides are different lengths, but the shape is the same.</em>

I hope this helps! Please feel free to comment below if you need any clarification. Have a good day, and good luck on your assignment. :)
