The correct answer for the completion exercise shown above is the first option (Option a), which is:

 a. Subtract 3; -7, -10, -13

 The explanation is shown below:

 1. You have the following sequence  5, 2, -1, -4

 2. The first second number is the result of a substraction:

 5-3=2

 3. Then you have:

 2-3=-1
 -1-3=-4
 -4-3=-7
 -7-3=-10
 -10-3=-13

 Therefore, the answer is the optiones mentioned before.

Answer:

A.Subtract 3:-7,-10,-13

Step-by-step explanation:

We are given that a sequence

5,2,-1,-4,...

We have to identify  the pattern of the givens sequence and next three terms.

a_1=5,a_2=2,a_3=-1,a_4=-4

a_2-a_1=2-5=-3

a_3-a_2=-1-2=-3

a_4-a_3=-4-(-1)=-3

The difference between two consecutive terms are equal.When the difference between two consecutive terms are equal then the sequence is called arithmetic sequence.Hence, the sequence is arithmetic sequence.

a_5=a_4-3=-4-3=-7

a_6=a_5-3=-7-3=-10

a_7=a_6-3=-10-3=-13

Answer:A.Subtract 3:-7,-10,-13

Given that AB is a diameter of circle O, find the missing angle and arc measures. ITEMBANK: Move to Bottom 116°154°26°32°64° https://www.usatestprep.com/modules/gallery/files/75/7534/7534.png
Solution 1

Answer:

M arc CB=64°,M<AOC= 116° ,M arc AD=26°,M arc DFB=154°,M<CDB=32°.

Step-by-step explanation:

Measure of central angle is equal to the measure of intercepted arc .Given <COB= 64°.Hence M arc CB=64°.

<AOC= 180-64= 116°.( Angles made on a straight line is supplementary)

Measure of intercepted arc is twice the angle made on the circumference.

It is given <ABD= 13 °.Hence intercepted arc AD =2x13=26°.

Marc DFB=180-26=154°.Measure of arc of a semicircle is 180°.

M< CDB=64÷2=32°( angle made on circumference is half the angle made at the centre.)

Question
The simple formula for the nth term of an arithmetic sequence is an = 5n + 15. What is the explicit formula corresponding to the simple formula? A. an = 15 + 5n B. an = 15 + (n - 1)(5) C. an = 20 + (n)/(5) D. an = 20 + (n - 1)(5) E. an = 5 + (n - 1)(15)
Solution 1
Sequence will look like this:
Term 1: 20 --------- 20 + 5(0)
Term 2: 25 --------- 20 + 5(1)
Term 3: 30 --------- 20 + 5(2)
Term 4: 35 --------- 25 + 5(3)
ETC.

It cab noted that the numbers in the bracket (that is, 0, 1, 2, 3, 3, etc) = n-1

Then, the explicit formula will be;
an = 20 + 5(n-1).

The correct answer is D.
Question
I need help with math!!! time is running out!!! will mark brainliest!!! PLEASE TAKE A LOOK AT ALL PHOTOS, TO ANSWER THE QUESTION. 1ST PHOTO IS THE QUESTION THE OTHERS ARE THE ANSWER CHOICES!
Solution 1
I see the question last and the 4 choices first.
Look at the points you have in the table with the question.
(0, 0), (4, 2), (9, 3)
The only graph that contains those three points is the second option.

Question
Which sequence is modeled by the graph below? coordinate plane showing the points (1, 1) (2, 2) (3, 4) and (4, 8) a. an = 1(2)n − 1 b. an = 2(1)n − 1 c. an = 1 + (2)n − 1 d. an = (2)(n − 1)
Solution 1
The y-values of 1, 2, 4, 8 imply an exponential function of base 2. At n = 1, y = 1 = 2^0. We can substitute into the various choices to determine the correct equation, which turns out to be a_n = 2^(n-1).
Solution 2

Answer: The correct option is d.

Explanation:

From the given information it is noticed that the coordinate plane showing the points (1, 1) (2, 2) (3, 4) and (4, 8).

The coordinates are in the form of (x,y), it means the value of xth term of the sequence is y.

The point (1,1) represents that the first term is 1. Similarly from  (2, 2) (3, 4) and (4, 8) points we can say that the second term is 2, third term is 4 and fourth term is 8.

The sequence is 1,2,4,8.

It can be written as,

2^0,2^1,2^2,2^3

Since the base is common that is 2 and the power is one less than the position of term. So the sequence is in the form of,

a_n=2^{n-1}

Therefore, the correct option is d.

Question
Change 8/10 to hundredths
Solution 1
You can't really do this without changing the value of the number.

But to do this, just multiply the denominator, 10, by 10, because 10 x 10 = 100.
Do not multiply 8 by 10 or anything. So, now your fraction is 8/100, or 0.08, or 8 hundredths.

98 POINTS PLEASE HELP --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Determine the standard form of the equation for the circle With center (h,k)=(-5,1/2) and radius r=1 A) (x-5)^2 + (y + 1/2)^2 = 1 B) (x-5) + (y - 1/2) = 1 C) (x+5)^2 + (y - 1/2)^2 = 1 D) (x+5)^5 + (y- 1/2)^2 = 105/2
Solution 1
The standard form of a circle is (x-h)^2+(y-k)^2=r^2.  We will fill in our h, k and r accordingly.  (x-(-5))^2+(y- \frac{1}{2})^2=1^2   which simplifies down to  (x+5)^2+(y- \frac{1}{2})^2=1   choice C.  There you go!

Question
Which event is considered neither likely nor unlikely? A. rolling a number greater than one on a six-sided number cube B. rolling a 1 on a six-sided number cube C. getting heads when flipping a coin D. choosing a X, Y, or Z from a bag containing all letters in the alphabet
Solution 1
Hey there 

The answer is D.
choosing a X, Y, or Z from a bag containing all letters in the alphabet.

There are 46 different  alphabets.
You have 3/46 chances
6% out of 100 of picking those letters 


Solution 2
A.) it is possible to roll a number greater than 1 on a six sided number cube.  - So it is likely.

B) It is possible to roll a 1.  - So it is likely.

C) It is possible to get a heads when flipping a coin.  - So it is likely.

D) It is possible to choose a X, Y or Z from the alphabets. - So it is likely.


Am sorry did not see any one that is neither likely nor unlikely.

There is likelihood in each of the Event, but to some varying degree.

I hope this helps.
