What is the first term of the fibonacci like sequence whose second term is 4 and whose fith term is 22?

Answers

Answer 1

Answer: -2

Step-by-step explanation:

The information in the question can be used to form an equation which goes thus:

2nd term = a + d = 4 ...... i

5th term = a + 4d = 22 ....... ii

From equation i

a = 4 - d ........ iii

Put equation iii into ii

a + 4d = 22

(4 - d) + 4d = 22

4 - d + 4d = 22

4 + 3d = 22

3d = 22 - 4

3d = 18

d = 18/3

d = 6

Commons difference is 6

Since a + d = 4

a + 6 = 4

a = 4 - 6

a = -2

The first term is -2

Answer 2

The first term of the fibonacci like sequence whose second term is 4 and whose fith term is 22 is -2

Given:

second term:

a + d = 4

fifth term:

a + 4d = 22

where

a = first be term

d = common difference

a + d = 4 (1)

a + d = 4 (1)a + 4d = 22 (2)

subtract (1) from (2)

4d - d = 22 - 4

3d = 18

d = 18 / 3

d = 6

substitute into (1)

a + d = 4 (1)

a + 6 = 4

a = 4 - 6

a = -2

Therefore, the first term of the sequence is -2

Martin and Isabelle go bowling. Each game costs $10, and they split that cost. Martin has his own bowling shoes, but Isabelle pays $3 to rent shoes.

Answers

Answer:

Martin's Bowling cost = $5x

Isabelle Bowling cost = $5x + 3

where x is the total games Martin and Isabelle played.

Step-by-step explanation:

As given,

There are 2 people - Martin and Isabelle

Each game costs = $10

Let they both play total games = x

⇒total game cost = $10x

As they split the cost , it means the cost is divided into half

⇒Martin game cost = $5x

Isabelle game cost = $5x

Also, given that Isabelle pays $3 to rent shoes.

⇒$3 is added to the Isabelle game cost

∴ we get

Isabelle game cost = $5x + 3

so, we get

Martin's Bowling cost = $5x

Isabelle Bowling cost = $5x + 3

Mason pulled his hamstring while at track practice and received an MRI. His medical bills totaled

$1,200. How much would he have to make in order to pay his bills if he did not use an FSA or HSA?

Answers

Answer:

a minimum of $1,200

Step-by-step explanation:

The flexible spending accounts (FSA) and health savings accounts (HSA) are basically accounts that help pay for your medical bills and therefore, drastically reduce the total amounts that you would have to pay out-of-pocket. Therefore, in this scenario, if Mason does not use an FSA or HSA then he would have to make a minimum of $1,200 to completely pay off his medical bill in full. Otherwise, he would still owe money.

Answer:

∠GJK is 22°

Step-by-step explanation:

Because the shape is a rectangle we know that GH is parallel to JI

This means that because of the alternate angle rule we know that

5x+8 = 7x-16

Then we solve for x

5x+8-5x = 7x-16-5x

8+16=2x-16+16

[tex]\frac{24}{2}[/tex]=[tex]\frac{2x}{2}[/tex]

x=16

So this means that ∠HJI is 68°

Because the shape is a rectangle we know that ∠GJI is a right angle

This means that ∠GJK is 90-∠HJI because of the angles on a right angle rule

90-68 =22

∴∠GJK is 22°

A rectangle with sides measuring x in. and 4x-1 in. has an area of 663in.^2. What are the dimensions of the rectangle?

Answers

9514 1404 393

Answer:

  13 in by 51 in

Step-by-step explanation:

The area is the product of the dimensions, so is ...

  663 = x(4x -1)

  4x^2 -x -663 = 0 . . . . . . subtract 663 to put in standard form

Using the quadratic formula, we can find the solutions.

  x = (-(-1) ±√((-1)^2 -4(4)(-663)))/(2(4))

  x = (1 ± √10609)/8 = (1 ±103)/8

Only the positive solution is of any use in this problem, so ...

  x = 104/8 = 13

  4x-1 = 4(13)-1 = 51

The dimensions of the rectangle are 13 inches by 51 inches.

Solve d=rt for r thanks!!!!

Answers

r = d/t :) Any questions? I got you.

Answer:

Step-by-step explanation:

So you know that distance = rate x time.

9 miles in 1.5 hours

In this case, you know the time (1.5 hours) and the distance (9 miles)

(You can ignore the rest of the chart since the question is just about running.)

What's missing is the rate (r) at which you ran. (Think of it as speed...)

If r x t = d, that means that d ÷ t = r

So plug in what you have: 9 ÷ 1.5 = your rate. And 9 ÷ 1.5 is...

6

So you ran 6 miles per hour. And you can check it: if you went 6 miles in one hour, you could go another 3 miles in another half an hour. That would be 9 miles in 1.5 hours. Check!

C. Overall, small dogs weigh more with less variation

D. Small dogs and housecats have the same median.

Answers

Answer:

B.

Step-by-step explanation:

For reference, the median for housecats is 11 and the median for small dogs is 9. So, by process of elimination, B is the correct answer.

The dot plot is solved and Overall, house cats weigh more with less variation.

What is a dot plot?

A dot plot, also known as a dot chart or dot graph, is a type of data visualization that displays the frequency of values in a dataset. It is a simple graphing technique that uses dots to represent data points on a horizontal or vertical axis.

Each data point in the dataset is represented by a dot placed above the corresponding value on the axis. If there are multiple data points with the same value, the dots are stacked vertically above that value. The resulting plot shows the distribution of data points along the axis, with the height of the stack of dots representing the frequency of each value.

Given data ,

Let the dot plot be represented as A and B

where the weights of house dogs and small dogs are plotted

Now , the median of house cats = 11

The median of small dogs = 9

Variation refers to the spread or dispersion of a set of data points. It measures how much the values in a dataset differ from the mean or from each other. There are several ways to calculate variation, including the range, variance, and standard deviation.

So , Overall, house cats weigh more with less variation.

Hence , the dot plot is solved

In these equations you solve it first.

Now to check your work you simply substitute it back in to see if the equation stands.

If the parent function is y = x², explain the transformation(s) that occur to get from
the parent function to y = 3x? – 2

Answers

The parent function is y = x²

If we vertically stretch it by a factor of 3, then we get to y = 3x²

So it's 3 times taller than it used to be. A point like (2,4) moves to (2,12) after applying this vertical stretch. Because it's stretched vertically, it becomes more narrow in the horizontal direction.

If we then shift that down by 2 units, then we arrive at the equation y = 3x²-2

So to summarize, we applied these two transformations:

Vertically stretch by a factor of 3Shift down 2 units

A farmer wants to fence a section of land for a horse pasture. Fencing costs $27 per yard. How much will it cost to fence the pasture?

Please help

Answers

Answer:

$16,875

Step-by-step explanation:

so we must take all of those to get how much fencing we need in total so we add all of those numbers leaving us with 1875 ft of fencing we need.

so if fencing costs $27 per yard we need to change the units

so there are 3 feet per yard so we divide 1875 by 3 leaving us with 625 yards of fencing

so now we multiply the 625 yards of fencing by the $27 per yard leaving us with $16,875 in total to spend for this farmer to fence his pasture for the horses
