Answer: First question for the slope that passes through (-7, -2) and (6,-2) is m = 0. For the line that passes through (5, 3) and 5, -7) is m = 1/0.

I hope this helps!

Step-by-step explanation:

(−7,−2) and (6,−2)

(x₁,y₁) = (−7,−2)

(x₂,y₂) = (6,−2)

y₂ − y₁ / x₂−x₁

= −2 − −2 / 6 − −7

= 0/13

m = 0

m = y₂ − y₁ / x₂ − x₁

= −7 − 3 / 5 - 5

= −100

m = 1/0

A set of reflections that would carry hexagon ABCDEF onto itself would be "x-axis, y=x, x-axis" or "y=x, x-axis, y-axis".

What is a combination of reflections?

Combination of Two Reflections. A point or object once reflected can further be reflected to form a new image. The axes of these reflections may be parallel to each other or they intersect each other at a point.

Given the coordinates of hexagon ABCDEF, it can be determined that a set of reflections that would carry the hexagon onto itself would be a combination of reflections over the x-axis and y-axis.

One possibility would be to reflect over the x-axis, then reflect over the y=x line, and finally reflect over the x-axis again.

This would take the hexagon from its original position to itself.

Another possibility would be to reflect over the y = x line, then reflect over the x-axis, and finally reflect over the y-axis.

This would also take the hexagon from its original position to itself.

Hence, a set of reflections that would carry hexagon ABCDEF onto itself would be "x-axis, y=x, x-axis" or "y=x, x-axis, y-axis".

The solution to the system of equations is (0, -5) or (4, 3).

What is the system of equations?

A system of equations is a set of two or more equations with the same variables. A solution to a system of equations is a set of values for the variable that satisfy all the equations simultaneously.

To solve the system of equations, we'll substitute the second equation into the first:

x^2 + (2x - 5)^2 = 25

Expanding the square in the second equation:

x^2 + 4x^2 - 20x + 25 = 25

5x^2 - 20x = 0

5x(x - 4) = 0

So x = 0 or x = 4.

For x = 0:

y = 2x - 5 = -5

For x = 4:

y = 2x - 5 = 3

Hence, the solution to the system of equations is (0, -5) or (4, 3).

The maximum number of interior angles of a convex polygon would be 7.

Imagine operating a small vehicle on a track with a polygonal shape. Your compass is handy (directional, not one for drawing circles). The automobile concludes the lap in the same direction as it began. If there was a compass, it has completed one full rotation.

180 - 131 = 49°

360/49 = 7.346938775510204

So 7 interior angles max

A convex polygon's outside angles add up to 360 degrees.

The volume of the largest right circular cylinder (in cubic units) that fits in a sphere of radius 4 units is 154.7 cubic units.

First, draw a diagram. The diagram shows the cylinder inscribed in the sphere. Given that in the diagram the height, h, we can find the radius of the cylinder in terms of r using the Pythagorean Theorem.

h represents half of the total height of the cylinder. choose h instead of h² to simplify things better.

To find the volume of the cylinder, we need to multiply the area of the top by the total height of the cylinder. In other words;

V = π(radius of cylinder)²(height of cylinder)

V = π(√r²−h²)²(2h)

V = 2πh(r²−h²)

V = 2π(r²h−h³)

d/dxV(h) = 2π(r²−3h²) = 0

The 2π divides out and we are left with;

r²−3h² = 0

After some rearranging;

h² = r²/3

Take the square root of both sides.

h = r/√3

To find the volume, we need to put this into the volume equation.

V = 2πh(r²−h²) = 2π(r/√3){r²−(r/√3)²}

V = (2πr/√3)(r²−r²/3)

V = (2πr/√3){(3r²−r²)/3}

V = (2πr/√3)(2r²/3)

V = 4πr³/3√3

V = 4√3πr³/9

Now, put the value of r in the above equation, and we get

V = 4√3π(4)³/9

V = 256√3π/9

V = 154.7 cubic units

Step-by-step explanation:

Answer:

Step-by-step explanation:

The sum of a geometric sequence can be found using the formula

Sn = a₁ (1 - rⁿ⁻¹)/ (1 - r)

where a₁ is the first term, r is the common ratio, and n is the number of terms.

In this case, a₁ = -8, r = -3, and n = 10.

Plugging these values into the formula, we get

Sn = -8 (1 - (-3)⁹⁻¹) / (1 - (-3))

Sn = -8 (1 + 3⁹) / 4

Sn = -8 (1 + 19683) / 4

Sn = -8 × 19684 / 4

Sn = -4920

Subtraction is one of the four arithmetic operation along with addition, multiplication and division. Subtraction is an operation that represents removal of objects from a collection. For example, in the adjacent picture, there are 5 minus 2 peaches, this means that 5 peaches with 2 taken away, resulting in a total of 3 peaches.

Ellen's pencils length = 2x+15

Tom's pencil length = 5x+25

Tom's pencil will be longer than Ellen's with;

Answer:the final answer is 7

Step-by-step explanation:

The distance between the tips of the hands is changing at a rate of 55 inches per minute at 9 o'clock.

To find the distance between the tips of the hands, we can use the Pythagorean theorem:

distance = $\sqrt{8^2 + 6^2} = \sqrt{64 + 36} = \sqrt{100} = 10$

As the clock moves, the minute hand will rotate 360 degrees in 60 minutes, or 6 degrees per minute, and the hour hand will rotate 360 degrees in 12 hours or 0.5 degrees per minute.

To find the rate at which the distance between the tips of the hands is changing, we need to find the rate at which the angle between the hands is changing.

We can use the fact that the angle between the hands is equal to the difference in the angular velocities of the hands.

Angular velocity of the minute hand = 6 degrees/minute

Angular velocity of the hour hand = 0.5 degrees/minute

Angular velocity of the distance between the tips of the hands = 6 - 0.5 = 5.5 degrees/minute

To convert this to distance per minute, we can use the fact that the distance between the tips of the hands is equal to the length of the hour and minute hand multiplied by the sine of the angle between them.

Distance per minute = 10 * 5.5 degrees/minute = 55 inches/minute

So, the distance between the tips of the hands is changing at a rate of 55 inches per minute at 9 o'clock.

The cost of painting the room walls with two coats of paint would be $84.38

To determine the cost of painting the room walls with two coats of paint, you would need to know the total square footage of the walls you are planning to paint. Once you have that information, you can calculate the total cost by multiplying the number of gallons of paint required by the cost per gallon. For example, if the room has 800 square feet of walls, you would need 2.28 gallons of paint (800/350 = 2.28) and the total cost would be $84.38 (2.28 x $36.50). If you want to know the cost of one coat, you will need to divide that number by 2.

The measure of angle R, in degrees, is 150°.

A parallelogram is a quadrilateral or four-sided shape, that has opposite sides that are parallel to each other. The opposite sides of a parallelogram are equal in length, and the opposite angles are also equal in measure.

In a parallelogram, opposite angles are equal, so if the measure of angle P is five times the measure of angle Q, then the measure of angle R must also be five times the measure of angle Q.

Let's call the measure of angle Q "x". Then the measure of angle P is 5x, and the measure of angle R is 5x.

Therefore, the measure of angle R in degrees is 5x degrees.

We know,

All of the angles added together = 360°

∠5Q +∠Q+∠5Q+∠Q = 360    Solve for Q

∠12Q = 360  

⇒  ∠Q = 30°

then ∠P = ∠5Q = 5(30) = 150°    

and,

 ∠P = ∠R    

⇒ ∠R = 150°
