Recursive formula for the given sequence is \(a_{n}=a_{n-1}-4\)

A recursive formula is a formula that defines any term of a sequence in terms of its preceding term(s).

Consider

The first term \(a_{1} =11\)

second term \(a_{2}=7\)

Common difference = 7-11 = -4

Third term \(a_{3}=3\)

Common difference = 3-7 =- 4

Fourth term \(a_{4}=-1\)

Common difference = -1-3= -4

Then the formula for the sequence is \(a_{n}=a_{n-1}-4\)

Hence, the Recursive formula for the give sequence is \(a_{n}=a_{n-1}-4\)

Step-by-step explanation:

Given that:

Earnings per week for Amber = $200

Total increase in the salary as per Amber's hard work = 100%

To find:

Earnings of Amber now?

Solution:

We are given the initial salary and its percentage increase.

We have to find the increased value of salary.

Increase in the salary = 100% of $200

\(\Rightarrow \dfrac{100}{100}\times \$200\\\Rightarrow \bold{\$200}\)

Amber's Current salary = Initial salary + Increase in the salary

Putting the values of the initial salary and increase in the salary:

Amber's Current salary = $200 + $200 = $400

The ladder and the top of the building form a right triangle

The building is 20.8 feet tall

The given parameters are:

The height (h) of the building is calculated using the following Pythagoras theorem

L^2 = b^2 + h^2

So, we have:

39^2 = 33^2 + h^2

Evaluate the exponent

1521 = 1089 + h^2

Rewrite as:

h^2 = 1521 - 1089

h^2 = 432

Take the square root of both sides

h = 20.8

Hence, the building is 20.8 feet tall

(a) To determine the radius and height of a cone with a given surface area and maximal volume, we need to find the critical points by differentiating the volume formula with respect to the variables, setting the derivatives equal to zero, and solving the resulting equations.

(b) To find the ratio for a cone with a given volume and minimal surface area, we follow a similar approach.

(c) A cone with a given volume and maximal surface area does not exist. This is because the surface area and volume of a cone are inversely proportional to each other.

Let's denote the radius of the cone as r and the height as h. The surface area of a cone is given by: A = πr(r + l), where l represents the slant height.

The volume of a cone is given by: V = (1/3)πr²h.

To maximize the volume while keeping the surface area constant, we can use the method of Lagrange multipliers.

The equation to maximize is V subject to the constraint A = constant.

By setting up the Lagrange equation, we have:

(1/3)πr²h - λ(πr(r + l)) = 0

πr²h - λπr(r + l) = 0

Differentiating both equations with respect to r, h, and λ, and setting the derivatives equal to zero, we can solve for the critical values of r, h, and λ.

(b) To find the ratio for a cone with a given volume and minimal surface area, we follow a similar approach. We set up the Lagrange equation to minimize the surface area while keeping the volume constant. By differentiating and solving, we can determine the critical values and calculate the ratio.

(c) A cone with a given volume and maximal surface area does not exist. This is because the surface area and volume of a cone are inversely proportional to each other. When one is maximized, the other is minimized. So, if we maximize the surface area, the volume will be minimized, and vice versa. Therefore, it is not possible to have both the maximum surface area and maximum volume simultaneously for a cone with given values.

The surface area of the prism is S = 57.1 mm²

The surface area of the prism is calculated as

The formula for the surface area of a prism is SA=2B+ph, where B, is the area of the base, p represents the perimeter of the base, and h stands for the height of the prism

Surface Area of the prism = 2B + ph

The area of the triangular prism is A = ph + ( 1/2 ) bh

Given data ,

Let the area of the 2 triangles be T

Let the area of the 2 rectangles be R

Let the area of the third side be U

Now , the total surface area of the prism = T + R + U

where T = 2 x ( 1/2 ) ( 4 x 4 )

T = 16 mm²

R = 2 x ( 3 x 4 )

R = 24 mm²

And , U = 5.7 x 3

U = 17.1 mm²

Therefore , the total surface area of prism S = 16 mm² + 24 mm² + 17.1 mm²

S = 57.1 mm²

Hence , the surface area of prism is S = 57.1 mm²

The groups found in the maps correspond to logical terms in the Boolean functions, and the reduced Boolean functions are derived by combining and simplifying these terms using the information provided by the maps. The maps serve as a visual aid in identifying the groups and their relationships, facilitating the simplification process and enabling the construction of optimized Boolean expressions.

1) The groups found in the maps are clusters of adjacent 1s or 0s in the truth table or Karnaugh map. These groups represent logical terms in the Boolean functions. In a Karnaugh map, the groups can be formed by combining adjacent cells horizontally or vertically, forming rectangles or squares. Each group corresponds to a term in the Boolean function.

2) The reduced Boolean functions derived from the maps are simplified expressions that represent the logical relationships between the input variables and the output. These reduced functions are obtained by combining and eliminating terms in the original Boolean functions. The maps help in identifying the groups and their corresponding terms, which can then be simplified using Boolean algebra rules such as absorption, simplification, and consensus.

The Karnaugh map is a graphical representation of a truth table that allows for visual analysis and simplification of Boolean functions. The map consists of cells representing all possible combinations of input variables, with the output values placed inside the cells. By examining the adjacent cells, groups of 1s or 0s can be identified. These groups represent logical terms in the Boolean functions.

To obtain the reduced Boolean functions, the identified groups are combined using Boolean algebra rules. Adjacent groups that differ by only one variable are merged to form larger groups. The resulting groups are then used to construct simplified Boolean expressions that represent the original functions. The simplification process involves eliminating redundant terms and applying Boolean algebraic rules such as absorption, simplification, and consensus.

Step-by-step explanation:

3.

the sum of all internal angles in a quadrilateral is always 360°.

so, the internal angle at x is given by

360 = 40 + 80 + 110 + inner angle

inner angle = 360 - 40 - 80 - 110 = 130°

an inner and an outer angle combined are together always 180°.

so,

130 + x = 180

x = 50°

4.

first, again, the sum of all inner angles is 360°.

this is a parallelogram. that means the diagonally opposing angles are equal.

so, the angle opposite of the 38° angle is also 38°.

that leaves

360 - 38 - 38 = 284°

for the 2 (again equal) remaining angles :

284 = 2 × angle

each of these remaining angles is then

284/2 = 142°

the angle JML is one of them.

so,

angle JML = 142°

Answer:

$850

Step-by-step explanation:

washer + dryer = $950

if washer cost=>$100

Therefore; the value of the dryer should be x

$100+x=$950

x=$850

The dryer cost is =>$850

Answer:

The dryer is $425.

Step-by-step explanation:

Washer = 100 + Dryer

Set up an equation:

Variable x = dryer

x + x + 100 = 950

x + x = 850

2x = 850

x = 425

Dryer = 425

Bonus answer:

Washer = 100 + x

Washer = 100 + 425

Washer = 525

Check your work:

Washer + Dryer = 950

525 + 425 = 950

950 = 950

The interest earned in 9 months is $25.45284

Step-by-step explanation:

The interest rate given by the bank = 4%

The rate at which the interest is applied = Quarterly

The amount of money deposited = $840

The formula for compound interest is given as follows;

\(Compound \ interest = P \times \left [ \left(1 + \dfrac{r}{n} \right )^{t \times n} - 1\right ]\)

Where;

P = The principal = $840

r = The rate = 4% = 0.04

n = The number of times the interest is compounded per period  = quarterly = 4

t = The time duration in period = 9 months = 3/4 × 1 year

Substituting the values gives the Compound interest C.I. as follows;

\(C.I. = 840 \times \left [ \left(1 + \dfrac{0.04}{4} \right )^{\dfrac{3}{4} \times 3} - 1\right ] = 840 \times \left [ \left(1 + \dfrac{0.04}{4} \right )^{ 3} - 1\right ] = \$ 25.45284\)

The interest earned in 9 months = $25.45284.
