The area of the face of a clock with a circumference of 14 inches is approximately 15.6 square inches. This is calculated using the formula for the area of a circle, which is πr², where r is the radius of the circle.

To find the area of the face of the clock, we need to use the formula for the area of a circle, which is

A = πr²

where A is the area of the circle, π (pi) is a constant approximately equal to 3.14, and r is the radius of the circle.

Since the circumference of the clock is 14 inches, we can use the formula for the circumference of a circle to find the radius

C = 2πr

14 = 2πr

r = 14 / (2π)

r = 2.227 in (approx)

Now that we know the radius, we can use the formula for the area of a circle

A = πr²

A = 3.14 x (2.227)²

A = 15.6 sq in (approx)

Therefore, the area of the face of the clock is approximately 15.6 square inches.

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°.

The coordinates of the vertices for the image if the preimage is translated 3 units up is : A′(−3, 6), B′(0, 10), C′(−3, 3).

The correct option is (B)

If we are given the translated image of something, we need to work backwards given the translation rules. For example, if we have a general translation of (x +a, y +b), then to find pre-translation coordinates, we do: (x−a, y−b).

We have the Triangle ABC has vertices at A(−3, 3), B(0, 7), and C(−3, 0).

Now, let's consider the translation that moves the triangle 3 units up. This means that we need to add 3 to the y-coordinate of each vertex to get the coordinates of the image.

So, the coordinates of the vertices of the image triangle, let's call it A'B'C', will be:

A' = (-3, 3+3) = (-3, 6)

B' = (0, 7+3) = (0, 10)

C' = (-3, 0+3) = (-3, 3)

The coordinates of the vertices for the image if the preimage is translated 3 units up is : A′(−3, 6), B′(0, 10), C′(−3, 3)

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.

Lol i am learning this to.

Answer:

Step-by-step explanation:

The triangles are not congruent.

Given that, two triangles, EFG and HIJ are similar,

So,

Since, the triangles are similar, but according to the definition of similarity, two objects that are similar are not necessarily congruent,

so the Δ EFG is not congruent to Δ HIJ.

Cos 30° = HI / HJ

√3/2 = 3/HI

HI = 3.5

Therefore, the scale factor Δ EFG to Δ HIJ = EF / HI = 10/3.5 = 2/0.7

The ratio of perimeter of similar objects are same as the scale factor,

so, the ratio of their perimeters = 2/0.7

The ratio of the areas of the similar objects are the ratios of the squares of the scale factor.

So, the ratio of their areas = 4/0.49

A, B, and D are the correct choices.

The similarity ratio between the two octagons is 1:2 (Option b).

To begin, we need to know that similar figures have the same shape, but they may differ in size. For instance, we can have two octagons with different areas but the same shape. In this case, we are given that the two octagons are similar, and we are given the areas of the two octagons.

Let the similarity ratio between the two octagons be "x". For areas, we know that the ratio of the areas of two similar figures is the square of their similarity ratio. Therefore, we can set up the following equation:

x² = (Area of smaller octagon) / (Area of larger octagon)

Substituting the given areas, we get:

x² = 4 / 16    

x² = 0.25

Taking the square root of both sides, we get:

x = √0.25

x = 0.5

Therefore, the similarity ratio between the two octagons is 1:2 (Option b).

The number of minutes of local landline calls is 132 min.

We are given that;

Now,

To find the number of minutes of local landline calls, we need to rearrange the tariff structure formula to solve for n in terms of Total and m. We also need to substitute the given values of Total and m.

Total = nx 12c/min +mX R1,10/min + R75,75

n = (Total - m x R1,10/min - R75,75) / (12c/min)

Total = R131.19

m = number of minutes of calls to cellphones = 36 min

n = (131.19 - 36 x 1.10 - 75.75) / 0.12

= (131.19 - 39.60 - 75.75) / 0.12

The entire area is under the standard normal distribution curve, which is 1 by definition.

In other words, a typical normal random variable has a 100% chance of landing anywhere within its range of potential values (-∞ to +∞).

This makes sense since the area under the standard normal distribution curve, which is a continuous probability distribution, shows the likelihood that the random variable will take on any value within its range. Since the entire area under the curve is 1, the likelihood that any potential value for the random variable will occur is 1, or 100%.

Step-by-step explanation:

You want the volume of Prism B similar to Prism A, where the volume of Prism A is 216 cm³, its height is 9 cm, and the height of Prism B is 3 cm.

The ratio of volumes is the cube of the ratio of heights:

  (Prism B volume)/(Prism A volume) = ((Prism B height)/(Prism A height))³

  (Prism B volume)/(216 cm³) = ((3 cm/(9 cm))³ = 1/27

  Prism B volume = (216 cm³)·(1/27) = 8 cm³

The volume is 8 cubic centimeters.

y = 7⁰ = 1, when x = 1

y = 7¹ = 7, when x = 2

y = 7² = 49, when x = 3

y = 7³ = 343, when x = 4

y = 7⁴ = 2401, when x = 5

30-60-90 triangle, which means that the base is 10. 1/2(10)(10 rt 3). Simplify answer as needed :)

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

where C is the constant of integration.

The three sides of the triangle are a, b, P - (a + b)

The length of the missing side, and the lengths of all three sides of a triangular corner shelf.

Given that one side of the triangular shelf measures "a" units and another side measures "b" units, we can find the total of two sides by adding them together:

a + b = total of two sides

If the perimeter of the triangle measures "P" units, we know that the perimeter is the sum of all three sides, so:

a + b + c = P

where "c" is the length of the missing side. We can rearrange this equation to solve for "c":

c = P - a - b

To find the lengths of all three sides of the triangle, we can substitute the value of "c" that we just found into the Triangle Inequality:

a + b > P - a - b

Simplifying this inequality, we get:

2a + 2b > P

Dividing both sides by 2, we get:

a + b > P/2

So, if "a + b > P/2", then the triangle can exist, and we can use the value of "c" that we found earlier to get the lengths of all three sides:

a + b + c = P

a + b + (P - a - b) = P

Step-by-step explanation:

If AOC and BOD are diameters of a circle, centre O, we can prove that triangle ABD and triangle DCA are congruent by RHS.

First, we can observe that angle AOB and angle COD are both right angles since they are angles subtended by diameters of the circle.

Since AO and BO are equal radii of the circle, they have the same length. Similarly, CO and DO are equal radii of the circle and have the same length. Thus, we have:

AO = BO = CO = DO

Now, consider triangle ABD and triangle DCA. We have:

AB = DC (both are diameters of the circle, hence have the same length)

AD = AD (common side)

∠ADB = ∠CDA = 90° (both are right angles)

Therefore, by the RHS (Right Angle-Hypotenuse-Side) congruence criterion, we can conclude that triangle ABD and triangle DCA are congruent.
