Given:

The objective is to find the area of triangle ABC

Explanation:

The general formula to find the area of a triangle is,

A = 1/2 *b*h

To find the area of triangle ABC:

The height of the triangle DC can be calculated using the Pythagorean theorem of triangle ADC.

DC  = √ 9 - 6.25

      =1.65

On plugging the given values in equation

Thus, the height of triangle ABC is 2.5

So the base of the triangle CB = 6 + 1.65 = 7.65.

Now, substitute the obtained values in equation

area = 1/2 * 7.65 * 2.5

        = 9.56

Hence, the area of triangle ABC is 9.56 square units .

The three consecutive even integers are 6, 8, and 10, which satisfy the Pythagorean Theorem.

We have,

The Pythagorean Theorem in a right-angled triangle,

a² + b² = c²

To find three consecutive even integers that satisfy this theorem, we can start by assuming that one of the even integers is x.

Then, the next two consecutive even integers would be x+2 and x+4.

We can then use the Pythagorean Theorem to set up an equation and solve for x:

x² + (x+2)² = (x+4)²

Expanding and simplifying:

x² + x² + 4x + 4 = x² + 8x + 16

Simplifying further:

x² - 4x - 12 = 0

Now we can use the quadratic formula to solve for x:

x = [4 ± √(4² - 4(1)(-12))] / (2 x 1)

x = [4 ± √64] / 2

x = [4 ± 8] / 2

x = 6 or x = -2

Since we are looking for three consecutive even integers, we can discard the negative solution and choose x = 6.

This gives us the three consecutive even integers: 6, 8, and 10, which satisfy the Pythagorean Theorem:

6² + 8 = 10²

36 + 64 = 100

100 = 100

Thus,

The three consecutive even integers are 6, 8, and 10, which satisfy the Pythagorean Theorem.

Answer:

The sum of the interior angle measures of a regular hexagon is 720°.

Step-by-step explanation:

To find the sum of the interior angle measures of a regular hexagon, we can use the fact that any polygon can be divided into triangles. The formula to find the sum of the interior angles of any polygon with n sides is:

Sum of interior angles = (n - 2) × 180°

In the case of a hexagon, n = 6. So, we can plug this value into the formula:

Sum of interior angles = (6 - 2) × 180° = 4 × 180° = 720°

The sum of the interior angle measures of a regular hexagon is 720°.

To explain this using triangles, let's divide the hexagon into triangles. A hexagon can be divided into four triangles by drawing three diagonals from one vertex to the three non-adjacent vertices. Since the sum of the interior angles of each triangle is 180°, and we have four triangles:

Sum of interior angles of hexagon = 4 × 180° = 720°

The sum of the interior angle measures of a regular hexagon is 720°.

Answer:

It’s 2.07 pounds/in 3

Step-by-step explanation:

1 kilogram = 2.2 × pounds, so,2.07 × 1 kilogram = 2.07 × 2.2 pounds (rounded), or2.07 kilograms = 4.554 pounds.Step 2: Convert the decimal part in pounds to ouncesAn answer like "4.554 pounds" might not mean much to you because you may want to express the decimal part, which is in pounds, in ounces which is a smaller unit.So, take everything after the decimal point (0.55), then multiply that by 16 to turn it into ounces. This works because one pound equals 16 ounces. Thus,4.55 pounds = 4 + 0.55 pounds = 4 pounds + 0.55 × 16 ounces = 4 pounds + 8.8 ounces. So, 4.55 pounds = 4 pounds and 8 ounces (when rounded). Obviously, this is equivalent to 2.07 kilograms. Step 3: Convert from decimal ounces to a usable fraction of ounceThe previous step gave you the answer in decimal ounces (8.8), but how to express it as a fraction? See below a procedure, which can also be made using a calculator, to convert the decimal ounces to the nearest usable fraction: a) Subtract 8, the number of whole ounces, from 8.8:8.8 - 8 = 0.8. This is the fractional part of the value in ounces.b) Multiply 0.8 times 16 (it could be 2, 4, 8, 16, 32, 64, ... depending on the exactness you want) to get the number of 16th's ounces:0.8 × 16 = 12.8.c) Take the integer part int(12.8) = 13. This is the number of 16th's of a pound and also the numerator of the fraction.Finalmente, 2.07 quilogramas = 4 pounds 8 3/4 ounces.A fração 12/16 não está simplificada, e ainda pode ser reduzida para 3/4 para que possamos expressar como a fração mais simples possível.In short:2.07 kg = 4 pounds 8 3/4 ounces

Step-by-step explanation:

1) A system of equations has no solution if the graphs of the equations do not intersect.  2) A system of equations has exactly one solution if the graphs of the equations intersect at exactly one point.  3) A system of equations has exactly two solutions if the graphs of the equations intersect at exactly two points.

Systems with no solution

A system of equations has no solution if the graphs of the equations do not intersect. This can happen if the graphs are parallel, or if one graph is completely contained within the other graph.

For example, the graph of a linear equation is a line, and the graph of a quadratic equation is a parabola. If the line and the parabola are parallel, then they will never intersect, and the system will have no solution.

Another way for a system to have no solution is if one graph is completely contained within the other graph. For example, the graph of the equation y = x is completely contained within the graph of the equation y = [tex]x^2[/tex]. This means that there are no points that satisfy both equations, and the system will have no solution.

Systems with exactly one solution

A system of equations has exactly one solution if the graphs of the equations intersect at exactly one point. This can happen if the graphs are intersecting lines, or if the graphs are intersecting parabolas.

For example, the graph of the equations y = x and y = [tex]x^2[/tex] intersect at exactly one point, which is the point (0,0). This is because the two graphs intersect when x = 0, and there is no other point where they intersect.

Systems with exactly two solutions

A system of equations has exactly two solutions if the graphs of the equations intersect at exactly two points. This can happen if the graphs are intersecting parabolas that have different slopes.

For example, the graph of the equations y = [tex]x^2[/tex] and y = 2[tex]x^2[/tex] intersect at exactly two points, which are the points (0,0) and (1,1). This is because the two graphs intersect when x = 0 and when x = 1, and there are no other points where they intersect.

Answer:

The amount of money the painter earns, in dollars, depends on the number of rooms he paints.

For each room painted, the painter charges $25. Therefore, the amount of money earned, y, is given by the equation:

y = 25x + 100

where x is the number of rooms painted and 100 is the cost of supplies.

To graph this equation, we can plot a point on the y-axis where x=0 (the fixed cost of supplies) at (0, 100), and then use the slope of 25 to find additional points. For example, when x=1, y=125; when x=2, y=150; and so on.

With this information, we can eliminate options (b) and (d) because they both show negative slopes, which would mean the painter loses money as he paints more rooms.

Option (c) shows a positive slope, but the line goes through the point (0,100) and (4,200), which means the painter earns $200 after painting 4 rooms, but this contradicts the given information that the painter charges $25 per room. Therefore, option (c) is also incorrect.

Option (a) correctly shows the slope of 25 and goes through the point (0, 100), and the line reaches the x-axis when x=4, indicating that the painter earns $0 after painting 4 rooms. This matches the given information that the painter charges $25 per room. Therefore, the correct answer is option (a).

Therefore, the graph that shows the relationship between the amount of money the painter earns, in dollars, and the number of rooms he paints is:

a coordinate grid with the x axis labeled rooms painted and the y axis labeled amount of money earned and a line going from the point 0 comma 100 through the point 4 comma 0

Answer:

The correct answer is a C. coordinate grid with the x axis labeled rooms painted and the y axis labeled amount of money earned and a line going from the point 0 comma 100 through the point 4 comma 200.

The painter pays $100 for supplies, so he will only earn money for the rooms he paints after he has recouped that cost. The first room he paints will earn him $25, the second will earn him $50, and so on. After he has painted 4 rooms, he will have earned $200.

The graph of this relationship would be a line that starts at the point (0, 100) and goes up to the point (4, 200).

Area of Rectangle = Length x Width

Given data ,

Let the area of the rectangle be A

Now , the length of the rectangle be L

Let the width of the rectangle be W

Let's assume that the length of the rectangular plot of land is L meters and the width is W meters. Since Jamal has only 44 meters of fencing available, the perimeter of the enclosure will be 44 meters:

Perimeter = 2L + W = 44

W = 44 - 2L

The area of the rectangular plot of land is given as 192 square meters

Area = L x W = L x (44 - 2L) = 192

2L² - 44L + 192 = 0

Solving for L using the quadratic formula, we get:

L = (44 ± √(44² - 4 x 2 x 192)) / (2 x 2)

L = (44 ± √(1600)) / 4

L = (44 ± 40) / 4

So, the possible values of L are 11 and 8

If L = 11, then W = 44 - 2L = 22, and the dimensions of the rectangular plot of land are 11 m x 22 m

Answer:   The simple interest on a sum of money invested at 3% per annum for 2 1/2 years is N9.225, and the principal is N3,000.

Step-by-step explanation:

We can use the formula for simple interest:

I = P * r * t

where I is the interest, P is the principal, r is the interest rate, and t is the time in years.

Given that the interest is N123, the interest rate is 3% per annum, and the time is 2 1/2 years, we can plug these values into the formula and solve for the principal:

123 = P * 0.03 * 2.5

Simplifying, we get:

123 = 0.075P

P = 123 / 0.075

P ≈ 1,640

Therefore, the principal is approximately N1,640.

However, this principal value does not correspond to the given interest amount of N9.225. To obtain the correct principal, we need to use the correct interest amount:

We can convert the time of 2 1/2 years to 5/2 years, and use the formula for simple interest:

I = P * r * t

where I is the interest, P is the principal, r is the interest rate, and t is the time in years.

Given that the interest is N9.225, the interest rate is 3% per annum, and the time is 5/2 years, we can plug these values into the formula and solve for the principal:

9.225 = P * 0.03 * 5/2

Simplifying, we get:

9.225 = 0.0375P

P = 9.225 / 0.0375

P = 246

Therefore, the principal is N246.

The integral of 1/(2+4x²+25x²) using partial integration is (1/2) arctan(10x) + C, where C is the constant of integration.

To solve this integral, we will use the technique of partial integration. This technique is also known as integration by parts and is used to find the integral of a product of two functions. The formula for integration by parts is as follows:

∫u dv = uv - ∫v du

where u and v are functions, and du/dx is the derivative of u with respect to x, and dv/dx is the derivative of v with respect to x.

Let's apply this formula to our integral:

∫1/(2+4x²+25x²) dx

We need to choose two functions, u and dv, such that when we differentiate u, we get a simpler function, and when we integrate dv, we get a simpler function. In this case, we can choose:

u = 1, and dv = 1/(2+4x²+25x²) dx

Now, let's find du/dx and v:

du/dx = 0 (since u is a constant)

To find v, we need to integrate dv. We can use the substitution method to evaluate the integral:

Let u = 5x

du/dx = 5

dv = 1/(2+4x²+25x²) dx

Substituting u and dv:

v = ∫ dv/dx du = ∫1/(2+4u²) du

v = (1/2) arctan(2u)

v = (1/2) arctan(2(5x))

v = (1/2) arctan(10x)

Now, we can apply the formula for integration by parts:

∫1/(2+4x²+25x²) dx = uv - ∫vdu

∫1/(2+4x²+25x²) dx = (1) x (1/2) arctan(10x) - ∫(1/2) arctan(10x) x 0 dx

∫1/(2+4x²+25x²) dx = (1/2) arctan(10x) + C

To divide 18 by 5.5, we can use long division method as follows:

       _________

   5.5 | 18.0000

       -16.5

       ------

        1.5

We first divide 5.5 into the first digit of 18, which is 1. This gives us 0 as the whole number part of the quotient. We then multiply 0 by 5.5 to get 0, and subtract it from 1, which gives us 1.

We then bring down the next digit 0 and get 10. We then divide 5.5 into 15, which gives us 2 as the whole number part of the quotient. We then multiply 2 by 5.5 to get 11, and subtract it from 15, which gives us 4.

We then bring down the next digit 0 and get 40. We then divide 5.5 into 40, which gives us 7 as the whole number part of the quotient. We then multiply 7 by 5.5 to get 38.5, and subtract it from 40, which gives us 1.5.

Since there are no more digits to bring down and the remainder is less than the divisor 5.5, we can stop here. Therefore, the result of 18 divided by 5.5 is approximately 3.27, which we get from the quotient of 0.327 rounded to two decimal places.

So 18 divided by 5.5 is approximately 3.27 or 3.27 to two decimal places.
