The force of repulsion between two people, each with the charge calculated in part (a), separated by a distance of 100 m, is approximately 0.0152 N.

The Earth has a net electric charge that generates a field near its surface, which is equal to 150 N/C directed towards the center of the planet. Let's address the questions:

(a) To overcome the weight of a human with the force exerted by the Earth's electric field, we need to calculate the electric force required.

The electric force (Fe) is given by the equation:

Fe = q * E

Where:

Fe is the electric force,

q is the charge, and

E is the electric field strength.

The weight (W) of the human is given by the equation:

W = m * g

Where:

W is the weight,

m is the mass of the human, and

g is the acceleration due to gravity.

Since the electric force and weight should be equal to achieve equilibrium, we have:

Fe = W

Therefore:

q * E = m * g

Rearranging the equation, we can solve for q:

q = (m * g) / E

Substituting the given values:

q = (60 kg * 9.8 m/s²) / 150 N/C

Calculating the value:

q ≈ 3.92 × 10⁻³ C

The charge required for a human to overcome their weight with the Earth's electric field is approximately 3.92 milli Coulombs. The sign of the charge would depend on whether the charge is positive or negative.

(b) To calculate the force of repulsion between two people with the charges calculated in part (a), we can use Coulomb's Law. Coulomb's Law states that the force of repulsion between two charges is given by:

F = k * (|q1| * |q2|) / r²

Where:

F is the force of repulsion,

k is the electrostatic constant (9 × 10^9 N m²/C²),

q1 and q2 are the charges, and

r is the distance between the charges.

Substituting the values:

F = (9 × 10^9 N m²/C²) * (3.92 × 10⁻³ C)² / (100 m)²

Calculating the value:

F ≈ 1.52 × 10⁻² N

The force of repulsion between two people, each with the charge calculated in part (a), separated by a distance of 100 m, is approximately 0.0152 N.

As for the feasibility of using the Earth's electric field as a means of flying, it is not practical. The magnitude of the electric field near the Earth's surface is relatively weak, and the forces involved are insufficient to counteract the weight of a human. Additionally, the charges required for such an effect would be extremely large and potentially dangerous. The Earth's electric field cannot be effectively used as a medium for flying.

The Area of the shaded portion is: 72 square inches

The formula for the area of a triangle is given by the formula:

Area = ¹/₂ * base * height

Now, to get the area of the shaded portion, we will get the area of the larger triangle and subtract the area of the smaller one from it.

Thus:

Area of larger triangle = ¹/₂ *  17 * 13 = 110.5 square inches

Area of smaller triangle =  ¹/₂ * 11 * 7 = 38.5 square inches

Thus:

Area of shaded portion = 110.5 square inches - 38.5 square inches

Area of shaded portion = 72 square inches

Step-by-step explanation:

4(5 + x)

To simplify the expression, we must use the distributive property. We need to multiply 4 by the each of the two terms inside the parentheses.

4(5 + x) = 4 × 5 + 4 × x = 20 + 4x

20 + 4x is equivalent to 4(5 + x).

20 + x is not equivalent to 20 + 4x, so 20 + x is incorrect.

Answer:

$577

Step-by-step explanation:

Let y = amount of money in the account.

Let x = number of months.

The withdrawals are always the same amount and occur every month, so this is a linear relation.

We are given two points of the relation: (5, 442) and (13, 226).

y = mx + b

m = (442 - 226)/(5 - 13) = 216/(-8) = -27

The slope, -27, represents the amount she withdraws each month.

y = -27x + b

442 = -27(5) + b

442 = -135 + b

b = 577

y = -27x + 577

b = y-intercept = initial amount

As a mixed fraction, the expression yields -1 5/12.

A mixed fraction is one that is represented by its quotient and remainder. 2/3, for example, is a mixed fraction in which 2 is the quotient and 1 is the remainder. A mixed fraction is thus the product of a whole number and a proper fraction.

Step 1: Substitute an improper fraction for the mixed number.

Step 2: Rewrite the whole number as a fraction with the denominator 1 as the denominator.

Step 3: Multiply two fractions separately by multiplying the numerators and denominators. Step 4: If necessary, convert it to a simplified form.

Given the expression

1 ( 1/2) + (3/4) ÷ (-(1/3)) - (2/3)

Write as an improper fraction

(3/2) + (3/4) ÷  (-(1/3)) - (2/3)

Using the PEDMAS rule;

\(&=\frac{3}{2}+\left(\frac{3}{4} \div\left(-\frac{1}{3}\right)\right)-\frac{2}{3} \\\)

\(&=\frac{3}{2}+\left(\frac{3}{4} \times-3\right)-\frac{2}{3} \\\)

\(&=\frac{3}{2}-\left(\frac{9}{4}\right)-\frac{2}{3}\)

Find the LCM of the result

\(&=\frac{18-27-8}{12} \\\)

\(&=\frac{-17}{12} \\\)

\(&=-1 \frac{5}{12}\)

Hence, As a result, the expression as a mixed fraction yields -15 / 12.

The probability that the sample mean will be greater than M = 10 pounds is 0.9525.

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, with 0 indicating the event is impossible and 1 indicating it is certain. Probability is used in many fields, including mathematics, statistics, science, and finance.

To solve this problem, we need to use the central limit theorem (CLT), which states that the distribution of sample means will be approximately normal, regardless of the shape of the population distribution, as long as the sample size is large enough.

Since the sample size is small (n = 4), we need to use the t-distribution instead of the normal distribution. However, since the population standard deviation is known, we can use the standard normal distribution with a z-score.

First, we need to calculate the standard error of the mean:

SE = σ / sqrt(n) = 6 / sqrt(4) = 3

Next, we can calculate the z-score:

z = (M - µ) / SE = (10 - 15) / 3 = -1.67

Finally, we can use a standard normal distribution table or calculator to find the probability of a z-score greater than -1.67:

p(M > 10) = P(z > -1.67) = 0.9525 (rounded to four decimals)

Therefore, the probability that the sample mean will be greater than M = 10 pounds is 0.9525.

Step-by-step explanation:

Let us identify which quadratic function is positive. Yeah, let's start.

Y = \({ \red{ \sf{2 {x}^{2} - 17x + 30}}}\)

By using factorisation method,

\({ \red{ \sf{2 {x}^{2} - 12x - 5x + 30}}}\)

Take common factors

\({ \red{ \sf{2x(x - 6) - 5(x - 6)}}}\)

\({ \red{ \sf{(2x - 5)}}} \: \: \: \: \: \: \: || \: \: \: \: \: { \red{ \sf{(x - 6)}}}\)

\({ \red{ \sf{2x - 5 = 0}}} \: \: || \: \: { \red{ \sf{x - 6 = 0}}}\)

\({ \red{ \sf{2x = 5}}} \: \: \: \: \: \: \: \: \: || \: \: \: \: { \red{ \boxed{ \green{ \sf{x = 6}}}}}\)

\({ \red{ \sf{{ \frac{ \cancel2}{ \cancel2}x}}}} = { \red{ \sf{ \frac{5}{2}}}}\)

\({ \red{ \boxed{ \green{ \sf{x = \frac{5}{2}}}}}} \)

____________________________________

Y = \({ \blue{ \sf {{ - x}^{2} - 6x - 8}}}\)

By using factorisation method,

\({ \blue{ \sf{ - {x}^{2} - 2x - 4x - 8}}}\)

Take common factors

\({ \blue{ \sf{ - x(x + 2) - 4(x + 2)}}}\)

\({ \blue{ \sf{( - x - 4)}}} \: \: \: \: \: || \: \: \: \: \: { \blue{ \sf{(x + 2)}}}\)

\({ \blue{ \sf{- x - 4 = 0}}} \: \: \: \: \: || \: \: \: \: \: { \blue{ \sf{x + 2 = 0}}}\)

\({ \blue{ \boxed{ \green{ \sf{x = -4}}}}} \: \: \: \: \: || \: \: \: \: \: { \blue{ \boxed{ \green{ \sf{x = -2}}}}}\)

Hence, the first quadratic function is positive and second quadratic function is negative.

Answer:

\(\textsf{$y = 2x^2 - 17x + 30$: \quad $\left(-\infty, \dfrac{5}{2}\right) \cup (6, \infty)$}\)

\(\textsf{$y = - x^2 - 6x - 8$: \quad $\left(-\infty, -4\right) \cup (-2, \infty)$}\)

Step-by-step explanation:

A function is positive when it is above the x-axis, and negative when it is below the x-axis.

---------------------------------------------------------------------------------

Given quadratic equation:

\(y = 2x^2 - 17x + 30\)

Factor the equation:

\(\implies y = 2x^2 - 17x + 30\)

\(\implies y = 2x^2 - 5x-12x + 30\)

\(\implies y=x(2x-5)-6(2x-5)\)

\(\implies y=(x-6)(2x-5)\)

The x-intercepts of the parabola are when y = 0.

To find the x-intercepts, set each factor equal to zero and solve for x:

\(\implies x-6=0 \implies x=6\)

\(\implies 2x-5=0 \implies x=\dfrac{5}{2}\)

Therefore, the x-intercepts are x = ⁵/₂ and x = 6.

The leading coefficient of the given function is positive, so the parabola opens upwards.  

The function is positive when it is above the x-axis.

Therefore, the function is positive for the values of x less than the smallest x-intercept and more than the largest x-intercept:

---------------------------------------------------------------------------------

Given quadratic equation:

\(y = - x^2 - 6x - 8\)

Factor the equation:

\(\implies y = - x^2 - 6x - 8\)

\(\implies y = -(x^2 +6x +8)\)

\(\implies y = -(x^2 +4x +2x+8)\)

\(\implies y = -((x(x+4)+2(x+4))\)

\(\implies y = -(x+4)(x+2)\)

The x-intercepts of the parabola are when y = 0.

To find the x-intercepts, set each factor equal to zero and solve for x:

\(\implies x+4=0 \implies x=-4\)

\(\implies x+2=0 \implies x=-2\)

Therefore, the x-intercepts are x = -4 and x = -2.

The leading coefficient of the given function is negative, so the parabola opens downwards.  

The function is negative when it is below the x-axis.

Therefore, the function is negative for the values of x less than the smallest x-intercept and more than the largest x-intercept:

5x + 80 - 80 = 180 - 80

5x = 100
