Two unit squares share the same center. the overlapping region of the two squares is an octagon with perimeter 10/3. The area of the octagon is 0.833 square unit.

Let the octagon's eight successive vertices be A, B, C, D, E, F, G, and H.

Connect the squares' vertices to the shared center O by drawing the segments OA, OB, OC, OD, OE, OF, OG, and OH.

The octagon is divided into 8 triangles by the segments.

The bases of these triangles are AB, BC, CD, DE, EF, FG, GH, and HA; each triangle's height equals 1/2 of a unit.

Consequently, the octagon's surface area is

Area = (1/2) × (1/2) × (AB + BC + CD + DE + EF + FG + GH + HA)

Area = (1/4) × Perimeter of the octagon

Perimeter of the octagon = 10/3

Area = (1/4) × (10/3)

Area = 10/12

Area = 0.833 square unit.

The investment earned a rate of interest of approximately 22.7%, indicating a positive growth of the investment over the two-year period.

The rate of interest earned can be calculated using the formula for compound interest:

Rate of Interest = [(Final Value - Initial Value) / Initial Value] * 100

Using the given information:

Initial Value = $3,300

Final Value = $4,050

Substituting these values into the formula:

Rate of Interest = [($4,050 - $3,300) / $3,300] * 100

Calculating the numerator:

$4,050 - $3,300 = $750

Substituting the numerator into the formula:

Rate of Interest = [$750 / $3,300] * 100

Simplifying the expression:

Rate of Interest = (750 / 3300) * 100

Dividing the numerator by the denominator:

Rate of Interest ≈ 0.227 * 100

Rate of Interest ≈ 22.7%

Therefore, the rate of interest earned on the investment is approximately 22.7%. The formula for calculating the rate of interest is derived from the concept of compound interest. It measures the percentage increase in the initial investment that results in the final value.

To calculate the interest earned, subtract the initial value from the final value. In this case, the initial value is $3,300 and the final value is $4,050, resulting in an increase of $750. Divide this increase by the initial value to get the fraction gained, then multiply by 100 to express the rate of interest as a percentage.

In the given scenario, the investment earned a rate of interest of approximately 22.7%, indicating a positive growth of the investment over the two-year period.

Step-by-step explanation:

Given

\(y = 3x + 1.25\)

Required

What does the slope represent?

First, we need to determine the slope

A general equation is of the form

\(y = mx + b\)

Where

\(Slope = m\)

By comparing:

\(y = mx + b\) to \(y = 3x + 1.25\)

\(m = 3\)

Hence, the slope is 3

From the question we understands that a certain amount is paid per games.

This amount is represented by the rate or slope.

So:

The slope is the cost per game

The degree of the polynomial h(x) is 2.

The degree of a polynomial is determined by the highest power of the variable present in the polynomial.

Let's analyze the given expression:\(f(g(x)) \times g(h(x)) \times h(f(x)).\)

Since f(x) has a degree of 6, g(x) has a degree of 3, and h(x) is a polynomial, we can determine the degree of h(x) by examining the degree of the resulting polynomial.

When we substitute g(x) into f(x), the resulting polynomial will have a degree of\(6 \times 3 = 18,\) since we are effectively raising the degree of f(x) to the power of 3.

Similarly, when we substitute h(x) into g(x), the resulting polynomial will have a degree of \(3 \times h,\) since we are effectively raising the degree of g(x) to the power of h.

Lastly, when we substitute f(x) into h(x), the resulting polynomial will have a degree of h \(\times\) 6 since we are effectively raising the degree of h(x) to the power of 6.

Since the overall polynomial expression has a degree of 36, we can set up the equation:

\(18 + 3 \times h + 6 \times h = 36\)  

Simplifying the equation, we get:

9h + 18 = 36

9h = 18

h = 2

Step-by-step explanation:

The equation of the quadratic function is (c) f(x) = 3(x - 1)² - 2

From the question, we have the table of values that can be used in our computation:

A quadratic equation is represented as

f(x) = a(x - h)² + k

Where

Vertex = (h, k)

From the graph, we have the vertex to be

(h, k) = (1, -2)

Substitute (h, k) = (1, -2) in f(x) = a(x - h)² + k

So, we have

f(x) = a(x - 1)² - 2

Also, from the graph, we have the point (0, 1)

This means that

a(0 - 1)² - 2 = 1

So, we have

a(1) = 3

Divide both sides by 1

a = 3

Substitute a = 3 in f(x) = a(x - 1)² - 2

f(x) = 3(x - 1)² - 2

Hence, the equation is f(x) = 3(x - 1)² - 2

To calculate the speed of a racehorse in furlongs per fortnight, we need to convert the given speed from yards per second to furlongs per fortnight/ The horse's speed would be 0.001694 furlongs per fortnight.

Given that the horse is running at a speed of 6.00 yards per second, we can convert this speed to furlongs per fortnight. First, we need to convert yards to furlongs by dividing by the conversion factor of 220 yards per furlong:

6.00 yards/s / 220 yards/furlong = 0.02727 furlongs per second

Next, we need to convert seconds to fortnights. Since there are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 14 days in a fortnight, we can perform the necessary conversions:

0.02727 furlongs/s * 60 s/min * 60 min/hour * 24 hours/day * 14 days/fortnight = 334.84 furlongs per fortnight

Rounding to the appropriate decimal places, the horse's speed is approximately 0.001694 furlongs per fortnight.

Adam is 4 years old.

It will take 50 seconds for 50 printers to print out 50 pages of paper.

Given that the ages of Mark and Adam add up to 28 years in total, and Mark is 20 years older than Adam.

We are supposed to find Adam's age.

Age of Adam = A
Age of Mark = A + 20
Sum of their ages = 28A + (A + 20) = 28
Therefore, 2A + 20 = 28
Therefore, 2A = 8
Therefore, A = 4

Therefore, Adam is 4 years old.

Now let's move to the second question.
Let the time taken to print 50 pages be T seconds. Number of printers = 50
Time taken to print 50 pages = T
Therefore, time taken to print 1 page = T/50
Number of printers = 10
Time taken to print 10 pages = 10
Time taken to print 1 page = 1

T/50 = 1

Therefore, T = 50

Hence, it will take 50 seconds for 50 printers to print out 50 pages of paper.

Answer:

\(2\frac{1}{3}\)

Step-by-step explanation:

The improper fraction was 7/3 put that into a mixed number it it 2 1/3.

The value of the line integral ∫C F⋅dr = 1.193.

To evaluate the line integral ∫C F⋅dr, we first need to calculate F⋅dr, where F= 〈−4sinx, 4cosy, 10xz〉 and dr is the differential of the vector function r(t)= (2t^3,-3t^2,3t) for 0 ≤ t ≤ 1.

We have dr= 〈6t^2,-6t,3〉dt.

Thus, F⋅dr= 〈−4sinx, 4cosy, 10xz〉⋅ 〈6t^2,-6t,3〉dt

= (-24t^2sin(2t^3))dt + (-24t^3cos(3t))dt + (30t^3x)dt

Now we integrate this expression over the limits 0 to 1 to get the value of the line integral:

∫C F⋅dr = ∫0^1 (-24t^2sin(2t^3))dt + ∫0^1 (-24t^3cos(3t))dt + ∫0^1 (30t^3x)dt

The first two integrals can be evaluated using substitution, while the third integral can be directly integrated.

After performing the integration, we get:

∫C F⋅dr = 2/3 - 1/9 + 3/5 = 1.193

Therefore, the value of the line integral ∫C F⋅dr is 1.193.

In conclusion, we evaluated the line integral by calculating the dot product of the vector function F and the differential of the given path r(t), and then integrating the resulting expression over the given limits.

80% of ? = 150 x (80%/50%)
80/50 = 1.6

%/% = 1

1.6 x 1 = 1.6

80% of 300 = 150 x 1.6

150 x 1.6 = 240

80% of 300 = 240.

\(0.875x = 28\)

Solving for \(x\), we get:

\(\boxed{\begin{minipage}{4 cm}\text{\LARGE 0.875x = 28 } \\\\\\ \large $\Rightarrow$ $\frac{0.875x}{0.875}$ = $\frac{28}{0.875}$\\\\$\Rightarrow$x = 32\end{minipage}}\)

Answer:

slope = $50

Step-by-step explanation:

Given the linear equation, y = mx + b:

The slope (m) is the rate of change for every x number of labor hours. What this implies is that whenever the input (x-value) or the number of labor hours increases or decreases, the value of y (total cost) will increase by the given slope value.

Slope: The painting company charges $50 for every 1 hour of labor.

The y-intercept (b) represents the flat rate or initial value. In the given problem, it states that the company charges $500 for supplies. This means that regardless of whether the company finishes working on the painting job, they will charge their customers the flat rate.

Combined, the linear equation will be:
