The first five terms in a pattern are shown below.

-0.5, -0.25, 0, 0.25, 0.5, …

If the pattern continues, which expression can be used to find the nth term?

0.75n − 1.25
−0.25n − 0.25
0.25n − 0.75
−0.5n + 0.25

Answers

Answer 1

Answer:

I think this answer is A.

Step-by-step explanation:

I think this because when you subtract 0.5-0.25 you get 0.25. So you would add it to whatever comes next until you get to the 9th term. Then you would be somewhere around the ones place. :)

Answer 2

In the given pattern, the expression that can be used to find the nth term of the sequence is T(n)=0.25n-0.75. The correct option is C.

What is an Arithmetic Sequence?

An arithmetic sequence is a sequence in which the difference between any two consecutive terms of the sequence is equal.

Tₙ = a₁ + (n-1)r

where,

Tₙ is the nth term of the sequence,

a₁ is the first term of the sequence,

r is a common difference between every two terms.

Since the given sequence is in an arithmetic progression, therefore, the common difference between any two consecutive terms in the sequence are,

Difference, d = -0.25 - (-0.5)

                      = -0.25 + 0.5

                      = 0.25

Also, the first term of the sequence is -0.5. Therefore, using the formula of nth for an arithmetic sequence, we can write,

nth term = a₁ + (n - 1)d

              = -0.5 + (n - 1)0.25

              = -0.5 + 0.25n - 0.25

              = 0.25n - 0.5 - 0.25

              = 0.25n - 0.75

Hence, in the given pattern, the expression that can be used to find the nth term of the sequence is T(n)=0.25n-0.75.

Step-by-step explanation:

Okay so the 4(2t +2) and 4t + 8 + 4t go under 8t + 8, because when you distribute and add like terms, you get 8t+ 8 for both

(8*t)+(8*8) and 8t + 64 go under 8(t+8) because similar to the other, when you distribute and add like terms you get 8(t+8) for both

The last two options 8t+16 and (8+t) +(8+8) go under neither because when distributed and added, they don't match up to either or

42 can only go into 88 two times, so 42 x 2 = 84. So then 2 is your answer. BUT you have 4 left, so it's 2 remainder 4. If you want to round to the tenths, hundredths, ect, here is the original decimated number: 2.09523809524

16 laps 1 hour

How many laps did she walk in 2 hours?
Answer choices
48

32

Answers

the answer would be 32 laps in 2 hours. This is because if you walk 48 laps in 3 hours then you would have to figure out how many laps Mrs. banet walks in 1 hour. To do that you divide 48 by 3 and get 16 laps so 16 multiplied by 2 equals 32 which is how much you walk in 2 hours. Hope this helps :)

Find the equation of the line that contains the points (-5, 0) and (-3, 4)

Answers

Answer:

y = -1/2x - 5/2

Step-by-step explanation:

With points (-5,0) and (-3,4), we need to find the slope first.

[Find slope of points]

Using slope formula m = (Y2 - Y1) / (X2 - X1)

Using points: m = (4 - 0) / (-3 - 5) = 4/-8 = -1/2

[Use point-slope formula]

(y-y0) = m(x-x0)

Using points: (y - 0) = -1/2(x - -5)

Finally: y = -1/2x -5/2

Roland wants to buy a jacket that is discounted 20% off the regular price. Which of the following is NOT a valid way to determine the amount of the discount?

A
Move the decimal point of the original price one place to the left and then double it.

C
Multiply the original price times 0.2.

D
Divide the original price by 5.

C would be the answer because if you multiply 10 x 0.2 you will get 2 but if it is 20% off you would’ve gotten 5
