If f(1)=1 and f(n)=4f(n-1) what is the value of f(4)?

Answers

Answer 1

Answer:

  64

Step-by-step explanation:

You have the recursive formula f(1)=1; f(n)=4f(n-1) and you want f(4).

Recursion

The value of f(4) can be found a couple of ways. Perhaps the simplest is to compute the first 4 terms of the sequence using the recursive formula.

  f(1) = 1

  f(2) = 4·1 = 4

  f(3) = 4·4 = 16

  f(4) = 4·16 = 64

The value of f(4) is 64.

Explicit formula

The multiplying factor of 4 on the previous term tells you this is a geometric sequence with a common ratio of 4. The explicit formula is then ...

  f(n) = f(1)·r^(n-1) . . . . . n-th term of sequence with common ratio r

  f(n) = 1·4^(n-1) . . . . . . formula for f(1)=1 and r=4

For n=4, this is ...

  f(4) = 1·4^(4-1) = 4^3

  f(4) = 64

In a square, all the four side lengths have the same length, hence the value of x is obtained as follows:

6x - 1 = 4x + 6

2x = 7

x = 3.5 cm.

Explain why the probability of rolling a sum from 2 to 12 is 100%. [C:2]

Answers

The probability of rolling a sum from 2 to 12 on 2 dices is 100%

Given the data,

The two dice should be rolled.

Now, there are 36 possibilities that might occur while rolling two normal six-sided dice. The reason for this is that when rolling two dice, the total number of outcomes is the product of the numbers of outcomes for each die, and each die has six potential outcomes (numbers 1 through 6).

The resultant 36 results are as follows:

1-1, 1-2, 1-3, 1-4, 1-5, 1-6

2-1, 2-2, 2-3, 2-4, 2-5, 2-6

3-1, 3-2, 3-3, 3-4, 3-5, 3-6

4-1, 4-2, 4-3, 4-4, 4-5, 4-6

5-1, 5-2, 5-3, 5-4, 5-5, 5-6

6-1, 6-2, 6-3, 6-4, 6-5, 6-6

When using two dice, there are a total of 36 possibilities that might occur.

As a result, the results' total ranges from 2 to 12.

a family has a flower garden in the shape of a parallelogram in their backyard. they planted grass in the rest of the yard. fill in the boxes to complete each statement

Answers

The backyard is 9000 square feet, the flower garden is 60 square feet, and the grass space is 8940 square feet.

What exactly is a parallelogram?

A parallelogram is a special type of quadrilateral made up of parallel lines. As long as the opposite sides of a parallelogram are parallel, it can have any angle between its neighbouring sides. A parallelogram is formed when two opposite sides of a quadrilateral are parallel and congruent. As a result, a parallelogram is a quadrilateral with both pairs of opposite sides parallel and equal.

In their backyard, a family has a parallelogram-shaped flower garden.

A rectangle's area is equal to its length, width, and height, which total 9000 square feet.

The backyard is 9000 square feet in size.

The flower garden is shaped like a parallelogram with a 12-foot base and a 5-foot height.

A parallelogram's area is base height=125=60 square feet.

The flower garden is 60 square feet in size.

The remaining area is completely covered in grass. As a result, the area of the grassy area in the backyard is equal to the sum of the backyard's area and the size of the flower garden.

So the backyard is 9000 square feet, the flower garden is 60 square feet, and the grass space is 8940 square feet.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The total number of days worked in a week = 5 days.

Total number of hours in a week = 40

This means,

So,

In a week,

Answer:

\(m = 10\)

Step-by-step explanation:

Looking at the angles, we can see that this is a 30-60-90 triangle.

The side that is with the 30° angle and the 90° angle is represented by \(x\sqrt{3}\).

So let's find x.

\(x\sqrt{3} = 5\sqrt{3}\)

Divide both sides by \(\sqrt{3}\):

\(x = 5\).

Now the hypotenuse is always \(2x\) (the leg with the 90° and 60° is just x.) So,

\(2x = 2\cdot5 = 10\).

create a spider plot showing the effect on profit of varying the availability of resources (one at a time) between 90% and 110% of their base-case value in 2% increments.

Answers

To create a spider plot showing the effect on profit of varying the availability of resources, follow these steps:

1. Start by setting up your base-case values for each resource. This will be the starting point for your spider plot.

2. Next, create a series of data points for each resource by varying its availability between 90% and 110% of the base-case value in 2% increments. For example, if the base-case value for a resource is 100, you would create data points at 90, 92, 94, 96, 98, 100, 102, 104, 106, 108, and 110.

3. Plot these data points on a spider plot, with the base-case value at the center and the varying values radiating outwards. Each resource should have its own line or "spider leg" on the plot.

4. Finally, add labels and a legend to your spider plot to make it easy to understand which resource is represented by each line and what the varying values mean.

By following these steps, you can create a spider plot that clearly shows the effect on profit of varying the availability of resources.

Celeste is planting a rectangular flower garden in which the width will be 4 feet less than its length. She has decided to put a birdbath within the garden that will occupy a space 3feet by 4 feet how many feet are now left for planting? Express your answer on factored form

Answers

Answer:

(L-6)(L+2)

Step-by-step explanation:

Let L be the length of the flower garden.

Then the width will be L-4.

The area of the flower garden = L*(L-4) =L²-4L

The area of the birdbath is 3*4 = 12 ft²

The area of the remaining space for planting is

= Area of flower garden - area of birdbath

L² - 4L - 12

We can factor the expression as follows:

L² - 4L - 12 L²-(6-2)L-12L²-6x+2x-12

taking common frome each two terms

L(L-6)+2(L-6)(L-6)(L+2)

Therefore, the number of feet left for planting is (L-6)(L+2) in factored form.

snow falling per hour=2.5

trying to find how much snow has fallen after 5 hours.

First, lets put this into an equation, variables will go as follows

total amount of snow=S

hours=H

snow at beginning=B

Rate of snow fall=T

Now, we make an equation

S=T(H)+B

Now, substitute the variables out

S=2.5(5)+2

Then, solve

S=12.5+2

S=14.5
