Step-by-step explanation:

The number of feet the shoreline is eroding per year is 1 ⅓ feet.

How many feet are eroding per year?

Rate of shoreline eroding per 3 months = 1/3 foot

Number of 3 months in a year = 12 months / 3 months

= 4

Number of feets of the shoreline eroding per year = Rate of shoreline eroding per 3 months × Number of 3 months in a year

= 1/3 × 4

= 4/3 feet per year

Therefore, the shoreline erodes 1⅓ feet per year

The mean weight of the containers on the ship is found by adding the total weight of all the containers (270 tons) and dividing by the total number of containers (60), giving a mean of 4.5 tons per container.

In this problem, we are asked to find the mean weight of the containers on a ship. The mean is the average value of a set of numbers, found by adding all the numbers together and then dividing by the quantity of numbers.

First, let's compute the total weight of all the containers. The weight of the 30 small containers are 30 containers * 3 tons each = 90 tons. The weight of the 20 medium containers are 20 containers * 5 tons each =  100 tons. The weight of the 10 large containers are 10 containers * 8 tons each = 80 tons.

So, the total weight of all the containers is 90 tons + 100 tons + 80 tons = 270 tons. And the total number of containers is 30 + 20 + 10 = 60 containers.

So, the mean weight of the containers is 270 tons Total Weight / 60 = 4.5 tons/container. So, the mean weight of the containers on the ship is 4.5 tons.

Answer:

it is D (-1 + or - 2i square root of 2)

Step-by-step explanation:

just took test

The value of x obtained after solving the equation  x² + 2x + 9 = 0 will be x = -1 ±2i √(2)(x equals negative 1 plus or minus 2 I square root of 2).Option D is correct.

Any equation of the form ax²+bx+c=0  where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

As we know, the formula for the roots of the quadratic equation is given by:

[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]

it is given that,

x² + 2x + 9 = 0

Rearrange the equation as

x² + 2x  = - 9

Add 1 on both sides of the equation,

x² + 2x +1 = - 9 +1

x² + 2x +1 = - 8

(x+1)² = -8

Taking square root,

(x+1) = √ -8

Subtract 1 from both sides,

x+1-1 = -1 ±√(-8)

x = -1 ±√(-8)

√(-8) can be written as,

√(-8) = 2i√2

Substitute the values,

x = -1 ±2i sqrt(2)

Thus, the value of x obtained after solving the equation  x² + 2x + 9 = 0 will be x = -1 ±2i √(2)(x equals negative 1 plus or minus 2 I square root of 2).Option D is correct.

Answer:

B.(2,4)

Step-by-step explanation:

The equation for a circle is written as

(x-h)^2 +(y-k)^2 = r^2

where (h,k) is the center and r is the radius

(x-2)^2+(y-4)^2=9.

Rewriting this equation

(x-2)^2+(y-4)^2=3^2

The center is at (2,4)

Final answer:

To find the minimum value of C given the constraints, one must plot these constraints, find the feasible region's vertices, evaluate C at each vertex, and select the minimum value obtained. The minimum value of C = 4x + 3y, given the constraints and the corrected understanding of them, is 29.

Explanation:

To find the minimum value of C = 4x + 3y subject to the given constraints, we need to first correct the constraints provided, as it seems there might be a misunderstanding in how they were presented. Assuming the constraints meant to be:

1. [tex]\(x \geq 0\)[/tex]

2. [tex]\(y \geq 0\)[/tex]

3. [tex]\(2x + 3y \geq 6\)[/tex]

4.[tex]\(3x - 2y = 9\)[/tex]

5.[tex]\(x + 5y = 20\)[/tex]

We will solve the system of equations (4) and (5) to find the values of x and y that satisfy these conditions, and then we will check if these values satisfy all other constraints including (3). If they do, we'll use these values to find C.

Solving the equations simultaneously:

From equation (4): 3x - 2y = 9

From equation (5): x + 5y = 20

Multiplying equation (5) by 3 to eliminate x, we get:

3(x + 5y) = 3(20)

3x + 15y = 60

Now, subtract equation (4) from this result to eliminate x:

3x + 15y - (3x - 2y) = 60 - 9

3x + 15y - 3x + 2y = 51

17y = 51

y = 3

Substitute y = 3 into equation (5) to find x:

x + 5(3) = 20

x + 15 = 20

x = 5

Now, check if [tex]\(x = 5\) and \(y = 3\) satisfy the constraint \(2x + 3y \geq 6\):[/tex]

[tex]\[2(5) + 3(3) \geq 6\][/tex]

[tex]\[10 + 9 \geq 6\][/tex]

[tex]\[19 \geq 6\] - This is true.[/tex]

Since x = 5 and y = 3 satisfy all the constraints, we can calculate \(C\):

C = 4x + 3y

C = 4(5) + 3(3)

C = 20 + 9

C = 29

Therefore, the minimum value of C = 4x + 3y, given the constraints and the corrected understanding of them, is 29.

Solution:

The decreasing function is given as:

[tex]y = a(1-r)^t[/tex]

Where,

y is future value

a is initial value

r is decreasing rate

t is number of years

From given,

a = 4800

t = 5

[tex]r = 8.25 \% = \frac{8.25}{100} = 0.0825[/tex]

Therefore,

[tex]y = 4800(1 - 0.0825)^5\\\\y = 4800 \times 0.9175^5\\\\y = 4800 \times 0.6501\\\\y = 3120.841[/tex]

Thus the area after 5 years is 3120.841 square kilometer

Step-by-step explanation:

Answer:

As the value of x increases, the value of f(x) will eventually exceed the value of g(x) is the correct option.

Step-by-step explanation:

A function, f, passes through the points (1,1), (2,7) and (3,25).

The equation of the function 'f' can be written as:

The f(x) is obtained by:

                                      [tex]f\left(x\right)=3f\left(x-1_\right)+4[/tex]

                                      [tex]f\left(4\right)=3f\left(3\right)+4=\left(25\times 3\right)+4=75+4=79[/tex]

A function, g, passes through the points (1,36), (2,43) and (3,50).

The g(x) is obtained by:

                                       [tex]g\left(x\right)=g\left(x-1\right)+7[/tex]

                                  [tex]g\left(4\right)=g\left(4-1\right)+7=g\left(3\right)+7=50+7=57[/tex]

So, value of f(x) at x = 4 exceeds the value of g(x) at x = 4.

Therefore, as the value of x increases, the value of f(x) will eventually exceed the value of g(x) is the correct option.                                                                                                                                                          

Answer:

Step-by-step explanation:

The sum to n terms of an arithmetic sequence is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

Here a₁ = - 27 and d = 6, thus

[tex]S_{30}[/tex] = [tex]\frac{30}{2}[/tex] [ (2 × - 27) + (29 × 6) ]

     = 15( - 54 + 174)

     = 15(120)

     = 1800

The sum of the first 30 terms of the arithmetic sequence, is 1800.

In an arithmetic sequence, the sum of the first n terms can be calculated using the formula:

Sum = n/2 × (2a + (n-1)d), where:

Given:

Plugging in these values, we get:

Sum = 30/2 × (2(-27) + (30-1) × 6)

Calculating step-by-step:

Therefore, the sum of the first 30 terms of the arithmetic sequence is 1800.

Step-by-step explanation:

If (B) represents Bob's time, six minutes less than Bob's time is B-6=T where (T) represents the time six minutes less than Bob's time.

The phrase 'six minutes less than Bob's time' can be translated into the algebraic expression 'B - 6', where 'B' represents Bob's time.

The given phrase 'six minutes less than Bob's time' can be written as an algebraic expression. Algebraic expressions are mathematical phrases containing numbers, variables (like 'Bob's time'), and operations.  In this case, we can symbolize 'Bob’s time' as a variable, let’s choose 'B'. Then 'six minutes less than Bob's time' translates to 'B - 6' in an algebraic expression. That’s because 'less than' implies subtraction and it always means you subtract from the number or variable stated after the expression, in this case, 'Bob's time' or 'B'.
