An arithmetic sequence has this recursive formula:
a1=9
an=an-1 -3
What is the explicit formula for this sequence?
A. an=9+(n-1)(-3)
B. an=-3+(n-1)9
C. an=9+(n-3)(-1)
D. an=-1+(n-9)(-3)

Answers

Answer:

The correct answer is:

Option A. a_n=9+(n-1)(-3)

Step-by-step explanation:

Given that

a1 = 9

[tex]a_n = a_{n-1}-3[/tex]

We can see that in recursive formula the next term is being obtained by subtracting 3 from previous term

That means that the common difference is -3

We also know the first term

The general form of explicit formula for an arithmetic sequence is:

[tex]a_n = a_1 + (n-1)(d)[/tex]

We know that a1 = 9 and d = -3

Putting the values we get

[tex]a_n = 9+(n-1)(-3)[/tex]

Hence the correct answer is:

Option A. a_n=9+(n-1)(-3)

Answers

Answer: 2x7=14 present so

6x7=42

Step-by-step explanation:

2 presents=14 centimeters
6 presents= x centimeters
Cross multiply
2x=14x6
2x=84
Divide both sides by 2
X= 42
So he uses 42 centimeters of tape to wrap 6 presents

A five sided figure, the sum of all the angles must add up to 540 degrees.

In order to find x we are gonna add all the present angles and then minus the sum from 540 degrees.

76 + 144 + 112 + 125 = 457 degrees

540 - 457 = 83 degrees

Therefore x is equal to 83 degrees.

In the scale used on a blueprint .1\4 inch represents 2 feet,on the blueprint what is the length of a room with an actual length of 20 feet?

Answers

Answer: The length of the room on blueprint = 10 feet.

Step-by-step explanation:

Given: On blueprint,

[tex]\dfrac14[/tex] inch = 2 feet

i.e. 1 actual feet = [tex]2\times\dfrac 14 =\dfrac12\text{ inch}[/tex]

If the actual length of 20 feet, the length of a room on blueprint = [tex]20\times\dfrac12\text{ feet}[/tex]

= 10 feet.

Hence, the length of the room on blueprint = 10 feet.

1 1/2 m and 5/8 meter need to have the same denominator in order to subtract.

1 1/2 is equivalent to 12/8
Now 5/8 and 12/8 have the same denominator so you can subtract.
12/8-5/8= 7/8

Each of three friends—Lin, Jada, and Andre—had the goal of raising $40. How much money did each person raise?

Lin raised 100% of her goal.

Jada raised 50% of her goal.

Andre raised 150% of his goal.

Answers

Answer:

Down Below

Step-by-step explanation:

Lin: 100% of 40 = $40

Jada: 50% of 40 = $20

Andre: 150% of 40 = $60

The money raised by three friends is given below,

Lin raised 100% of her goal = $40

Jada raised 50% of her goal = $20

Andre raised 150% of his goal = $60

What is the percentage?

The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that Each of the three friends—Lin, Jada, and Andre—had the goal of raising $40.

The amount raised by all three friends will be calculated as,

Lin: 100% of 40 =40 x 1 = $40

Jada: 50% of 40 = 40 x 0.5 = $20

Andre: 150% of 40 =40 x 1.5 = $60

Therefore, Lin raised 100% of her goal which is $40 Jada raised 50% of her goal which is $20 and Andre raised 150% of his goal which is $60.

The Boy Who Cried Wolf There was once a young Shepherd Boy who tended his sheep at the foot of a mountain near a dark forest. It was rather lonely for him all day, so he thought upon a plan by which he could get a little company and some excitement. He rushed down towards the village calling out "Wolf, Wolf." The villagers came out to meet him, and some of them stopped with him for a considerable time. This pleased the boy so much that a few days afterwards he tried the same trick, and again the villagers came to his help. But shortly after this a Wolf actually did come out from the forest, and began to worry the sheep, and the boy of course cried out "Wolf, Wolf," still louder than before. But this time the villagers, who had been fooled twice before, thought the boy was again deceiving them, and nobody stirred to come to his help. So the Wolf made a good meal off the boy's flock, and when the boy complained, the wise man of the village said: "A liar will not be believed, even when he speaks the truth."
