The way that increasing the amount of charge on an object affects the electric force it exerts on another charged object is; The electric force increases because the amount of charge has a direct relationship to the force

The amount of charge on an object due to the effect of the force that is exerted on it can be calculated by using the formula :

F = E × q

Where;

F is the electric force.

E is the energy.

q is the charge.

The electric force between charged particles at rest is known as electrostatic force.

The magnitude of the electric force between point charges is directly proportional to the multiplication of the charges and inversely proportional to the distance between them.

Therefore, we conclude that increasing the amount of charge on an object would increase the electric force because the amount of charge has a direct relationship with the force.

Answer:

Step-by-step explanation:

Let's call the number of rows "x". The number of plants in each row would be 2x - 10. We know that the total number of plants is 600, so we can set up an equation:

x * (2x - 10) = 600

Expanding the left side:

x^2 + 10x - 600 = 0

We can solve for x using the quadratic formula:

x = (-10 ± √(10^2 - 4 * 1 * -600)) / 2 * 1

x = (-10 ± √(100 + 2400)) / 2

x = (-10 ± 50) / 2

x = 20 or -5 (but x cannot be negative, as the number of rows must be a positive integer)

So, there are 20 rows with 10 plants in each row. The number of plants in each row is 2x - 10 = 2 * 20 - 10 = 30.

[tex]slope = - \frac{8}{5} [/tex]

Step-by-step explanation:

So it looks like on the line, we have two dots.

Let's find those points, starting from the left one.

The left point is: (-1, 4) --- (x1, y1)

The right point is: (4, -4) --- (x2, y2)

**These are in (X, Y) form**

Now to find the slope, you use this equation

[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

Now let's plug our numbers into this equation

[tex]m = \frac{ - 4 - 4}{4 - ( - 1)} = \frac{ - 8}{5} = - \frac{8}{5} [/tex]

Answer:

y = -3(x + 0.5)² - 45.25

Step-by-step explanation:

a = -3

b = -3

c = -47

h = -b/2a = -(-3)/2(-3) = -1/2

k = c - b²/(4(-3)) = -46 - (-3)²/(-12) = -45.25

f(x) = -3(x - (-1/2))² - 45.25

y = -3(x + 0.5)² - 45.25

The system of equations is x + y = 16 & 6x + 4y = 76, then  the amount x is 6 yards of regular quilting fabric and the amount y is 10yards of sateen fabric she purchased.

She bought 6 Sateen fabrics and 10 quilting fabrics.

She uses quilt to make two types of fabrics.

Let the amount of each sateen fabric = x

Let the amount of each quilting fabric = y

The Sateen fabrics cost $6 per yard.

Therefore, for x amount it will be as follows:

6x

The quilting fabrics cost $4 per yard.

Therefore, for y amount it will be as follows:

4y

A system of equations is a collection of two or more equations with a same set of unknowns.

According to the condition the amount of quilting is 'x' and the amount of sateen is 'y', then the price of the quilting fabric is 6x and the price of then sateen fabric is 4y;

The 76$ she spends can be written as 4x+6y=76;

Total of 16 yards can be written as x+y=16;

So the required system of Equations is:

⇒4x+6y=76

⇒x + y=16

Therefore,

⇒x + y = 16

⇒6x + 4y = 76

⇒6x + 6y = 96

⇒6x + 4y = 76

⇒2y = 20

⇒y = 20 / 2

⇒y = 10

⇒x + y = 16

⇒x + 10 = 16

⇒x = 16 - 10

⇒x = 6

Therefore, the system of equations is x + y = 16 & 6x + 4y = 76, then  the amount x is 6 yards of regular quilting fabric and the amount y is 10yards of sateen fabric she purchased.

Step-by-step explanation:

    height = h = 2. 1m

    diameter = 0.7m

            radius = diameter ÷2

                    r  = 0.7 ÷ 2 = 0.35 m

Substitute the values of r and h in the below mentioned formula and find the surface area of the tank.

[tex]\boxed{Area \ of \ cylindrical \ tank = 2\pi r((r + h)}[/tex]

                                            = 2 * 3.14 * 0.35 (0.35 + 2.1)

                                            = 2 * 3.14 * 0.35 * 2.45

The sum of the interior angles of polygon A is 1260°.

The sum of angles of the exterior angles of a polygon A is 360°

Polygon A

A polygon with 9 sides is called a nonagon. The sum of interior angles of a Nonagon is 1260°. This can be calculated using the formula (n -2) * 180, where n is the number of sides.

Thus, the sum of the interior angles of polygon A is 1260°.

The sum of the exterior angles of a polygon is 360°.Thus, the sum of angles of the exterior angles of a polygon A is 360°.

Polygon B

Polygon B has 7 sides i.e. n = 7

sum of angles of the interior angles of polygon B = (7-4) * 180 = 900°

Thus, y = 900- 135 - 140 - 150 - 120 - 135 - 120 = 100°

x = 180 - 100 = 80°  (sum of angles on a straight line is 180°)

Answer:

Let x be the number of red M&Ms.

Then the number of blue M&Ms is x + 5, the number of yellow M&Ms is x - 9, and the number of brown M&Ms is (1/2)x + 13.

The total number of M&Ms is 135, so we can write an equation:

x + (x + 5) + (x - 9) + (1/2)x + 13 = 135

Simplifying this equation, we get:

3.5x + 9 = 135

Subtracting 9 from both sides, we get:

3.5x = 126

Dividing both sides by 3.5, we get:

x = 36

So there are 36 red M&Ms, 41 blue M&Ms (36 + 5), 27 yellow M&Ms (36 - 9), and 31 brown M&Ms (1/2 * 36 + 13).

Answer:

Step-by-step explanation:

r: the number of red M&Ms

b: the number of blue M&Ms

y: the number of yellow M&Ms

br: the number of brown M&Ms

We can translate the given information into equations:

r + b + y + br = 135 (the total number of M&Ms is 135)

b = r + 5 (there are five more blue M&Ms than red ones)

y = r - 9 (there are nine less yellow M&Ms than red ones)

br = 13 + (1/2)r (there are thirteen more brown M&Ms than half the number of red ones)

We can use equations 2, 3, and 4 to substitute for b, y, and br in equation 1:

r + (r + 5) + (r - 9) + (13 + (1/2)r) = 135

Simplifying this equation, we get:

3.5r + 9 = 135

Subtracting 9 from both sides, we get:

3.5r = 126

Dividing both sides by 3.5, we get:

r = 36

Now that we know the value of r, we can use equations 2, 3, and 4 to find the values of b, y, and br:

b = r + 5 = 36 + 5 = 41

y = r - 9 = 36 - 9 = 27

br = 13 + (1/2)r = 13 + (1/2)(36) = 31

Therefore, the number of red, blue, yellow, and brown M&Ms in the mixture are 36, 41, 27, and 31, respectively.

7.8 cm

Step-by-step explanation:

One tenth of a centimeter = [tex]\frac{1}{10} (1 cm)[/tex] = 0.1 cm . This means the answer has to be rounded to 1 decimal place.

Length of BE = Length of ED = [tex]\frac{6}{2}[/tex] = 3 cm

Focus on the triangles AED and CED. These two are right-angled triangles.

In both triangles, sides AE and CE are perpendicular sides, whose lengths will be calculated using Pythagorean Theorem:

Triangle AED:

[tex]AD^{2} = AE^{2} + ED^{2}[/tex]

[tex]AD^{2} - ED^{2} = AE^{2}[/tex]

[tex]AE^{2} = 6^{2} - 3^{2}[/tex]

Taking square root on both sides of the equation to get rid of the square:

[tex]AE = \sqrt{6^{2} -3^{2} }[/tex]

[tex]AE = \sqrt{36 - 9}[/tex]

[tex]AE = \sqrt{27}[/tex] cm

Triangle CED:

[tex]CD^{2} = CE^{2} + ED^{2}[/tex]

[tex]CE^{2} = CD^{2} - ED^{2}[/tex]

[tex]CE^{2} = 4^{2} - 3^{2}[/tex]

Taking square root on both sides of the equation to get rid of the square:

[tex]CE = \sqrt{4^{2} -3^{2} }[/tex]

[tex]CE = \sqrt{16 - 9}[/tex]

[tex]CE = \sqrt{7}[/tex] cm

Length of AC = Length of AE + Length of EC

∴ Length of AC = [tex](\sqrt{27} + \sqrt{7})[/tex] cm

You are able to simplify both of the 2/8ths and it comes to be 2/8 + 2/8 = 4/8

The value of t is 8 and the value of r is 8√2. The solution has been obtained by using trigonometry.

What is trigonometry?

The study of triangle sides, angles, and relationships is the focus of the mathematical field of trigonometry.

We are given a right angled triangle with an angle 45° and the perpendicular measuring 8.

Using trigonometry,

We know that tan theta = opposite side/ adjacent side

So,

⇒tan 45° = 8/t

⇒1 = 8/t (tan 45° = 1)

⇒t = 8

Similarly,

We know that cos theta = adjacent side/hypotenuse

So,

⇒cos 45° = 8/r

⇒1/√2 = 8/r (cos 45° = 1/√2)

⇒r = 8√2

Hence, the value of t is 8 and the value of r is 8√2.
