Answer: SECOND OPTION

Step-by-step explanation:

Substitute any value of <em>n</em> shown in the table attached into each function given in the options, and observe if you obtain the value of a_n shown in the table.

Let's substitute n=1 (According to the table, you need to obtain a_n=3):

<u>For the first option:</u>

f(1)=1+3=4

<u>For the second option:</u>

f(1)=7(1)-4=3  THIS IS THE FUNCTION

<u>For the third option:</u>

f(1)=3(1)+7=10

 <u>For the fourth option:</u>

f(1)=1+7=8

Therefore, the answer is the second option.

ANSWER

f(n) = 7n - 4

EXPLANATION

The terms of the sequence are;

3,10,17,24,31,...

This implies that,

a_1=3

The constant difference is

d = 10 - 3 = 7

The nth term of the sequence is;

a_n=a_1+d(n-1)

a_n=3+7(n-1)

a_n=3+7n - 7

a_n=7n-4

Or

f(n) = 7n - 4

The correct choice is B.

Find the perimeter of the figure to the nearest hundredth.
Kryger [21]

Hello!

Your answer should be 26.85.

We can use the formula of pi d or 2 pi r for the circumference.

You would get 5 pi.

But since its not a full circle you would divide it in half and get 2.5 pi.

2.5 pi is equal to 7.85.

Now we can use the equation 7.85 + 7 + 7 + 5

That would equal our answer... 26.85!

Hope this helps!

Consider the two triangles. Triangles A B C and H G I are shown. Angles A C B and H I G are right angles. The length of side A C
zheka24 [161]

Answer:

Both are similar by SAS similarity.

This SAS similarity is equivalent to the congruence.

Step-by-step explanation:

Step 1:

To prove that ACB and HIG as similar triangles.

We have to look upon the corresponding sides.

SAS= Side angle sides , there the angle must be in between two sides.

\angle ACB = \angle HIG

Lets work on the corresponding sides.

IG/AC = IH/AC

\frac{9}{15} = \frac{12}{20}

Reducing each to lowest form, we divide numerator and denominator by 3 for the 1st fraction and by 4 for the 2nd fraction.

We have

\frac{3}{5} = \frac{3}{5}

Both sides are equal.

So its proved that both are similar with SAS similarity theorem.

In a test (+5) marks are given for every correct answer and (-2) marks are given for every incorrect answer . Roy answered all t
katovenus [111]

Answer:

20 questions

Step-by-step explanation:

Given

Correct \Marks= +5

Incorrect\ Marks= -2

Score\ Obtained = 30

Number\ of\ correct\ answers = 10

Required

Number of questions answered

First, we need to get the total correct marks obtained by Roy

This is calculated by multiplying the correct marks by number of correct answers

Total = +5 * 10

Total = +50\ marks

Subtract this from the total scores obtained; This gives the total incorrect answer obtained by Roy

Incorrect = Scores\ Obtained - Total

Incorrect = 30 - (+50)

Open bracket

Incorrect = 30 - 50

Incorrect = -20

Divide this by -2 to get the number of incorrect answers

Incorrect\ Answers = \frac{-20}{-2}

Incorrect\ Answers = 10

Add this to the number of correct answers to give the total number of question answered

Total = Correct\ Answers + Incorrect\ Answers

Total = 10 + 10

Total = 20

<em>Hence, Roy answered a total of 20 questions</em>
