The required volume of the earth in cubic kilometers as per given hectares of land and its depth is equal to 0.0261 km³.

Hectare of land consumed by an open -pit coal mine = 87 hectares

Convert hectare into square meters

1 hectares = 10⁴ square meter

87 hectares = 87 × 10⁴ square meter

Depth = 30 m

Area of land = 87 × 10⁴ square meter

Volume of earth = area of land × depth

⇒ Volume of earth = 87 × 10⁴ m² × 30 m

⇒ Volume of earth = 261 × 10⁵ m³

1 kilometer = 10³meters

⇒1m³ = 10⁻⁹ km³

Volume of the earth = 261 × 10⁵ × 10⁻⁹ km³

⇒Volume of the earth = 261 × 10⁻⁴ km³

                                     = 0.0261 km³

Therefore, the volume of the earth as per given area of land and depth is equal to 0.0261 km³.

The equation P(t) = A - Bexp(-ct) can be used to model a worker's productivity after t hours on the job, where A, B, and c are positive constants.

We can then define the change in productivity over a brief period of time dt as

where P(t) is the productivity at time t. We can assume that dP(t) is negative because productivity is assumed to decrease over time.

As a result, the equation can be written as dP(t)/dt = -cP(t), or it can be rewritten as P(t) = Aexp(-ct), where A is a constant. P(t) = A - Bexp(-ct) can be obtained by adding a constant B to the right side of the equation to account for the fact that productivity can never be negative.

Answer:The linear function f with the given points is: f(x) = 3.

The linear function is a straight line that passes through two points (0, 3) and (-6, 3). This means that the equation of the line is given by y = mx + c, where m is the gradient of the line and c is the y-intercept. In this case, the 0,3 and -6,3 points have the same y-value, so the y-intercept is equal to 3.

To find the gradient of the line, we must use the formula m = (y2-y1)/(x2-x1). Therefore, the gradient of the line is m = (3-3)/(-6-0) = 0, meaning that the equation of the line is y = 3.

Assuming a binomial distribution for the number of auto accidents. If 7 in 10 auto accidents involve a single vehicle, the probability, p =[tex]\frac{7}{10}[/tex] = 0.7

Then the probability that the accident involved multiple vehicles is

q = 1 - p = 1 - 7/10 = 3/10 = 0.3

The slopes are :- -5, 1/3, -1/5, undefined, 1/4, -2/3, -1, -1, -2/3 and -5/2

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Given are the equations of the lines, we need to find the slope of the equation,

The general equation of a line is given by,

y = mx + c, where m is the slope and c is the y-intercept of the line.

So, finding slope of given equations by comparing them with the general equation,

1) y = -5x-1

m = -5, slope = -5

2) y = x/3-4

m = 1/3, slope = 1/3

3) y = -x/5-4

m = -1/5, slope = -1/5

4) x = 1,

Since, x=1 is a vertical line, the slope is undefined.

5) y = x/4+1

m = 1/4, slope = 1/4

6) y = -2x/3-1

m = -2/3, slope = -2/3

7) y = -x+2

m = -1, slope = -1

8) y = -x-1

m = -1, slope = -1

9) 2x+3y = 9

Converting into slope-intercept form,

2x+3y = 9

3y = -2x+9

y = -2x/3+3

m = -2/3, slope = -2/3

10) 5x+2y = 6

Converting into slope-intercept form,

5x+2y = 6

2y = -5x+6

y = -5x/2+3

m = -5/2, slope = -5/2

Hence, the slopes are :- -5, 1/3, -1/5, undefined, 1/4, -2/3, -1, -1, -2/3 and -5/2

When converting any dry component, keep in mind that a dry quart is equivalent to 4.6546 cups. A quarter gallon is equal to one quart in English (symbol: qt).

Without the actual values of b0 and b1, it is not possible to determine the predicted explanatory value. The correlation coefficient alone does not give enough information to make this prediction.

To find the predicted explanatory value that gives an average response value of 150, you would need to use the regression equation.

The regression equation takes the form:

y = b0 + b1x

where y is the response variable, x is the explanatory variable, b0 is the y-intercept, and b1 is the slope.

To find the x value that gives you a y value of 150, you would rearrange the equation as follows:

x = (y - b0)/b1

Plug in 150 for y and the y-intercept and slope values from your regression analysis to find the predicted explanatory value.

The percentage of the race he finished first is 40%

A number or ratio that can be expressed as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

Glenn raced his motorcycle 30 times and he finished first 12 times.

So, 12/30 = 2/5 = x/40

by using cross multiplication we get,

⇒ 5 * x = 2 * 100

⇒ 5 * x = 200

divided both side by 5 we get,

⇒ 5 * x / 5 = 200 / 5

⇒ x = 40

This function satisfies the conditions given: it is an nth-degree polynomial with real coefficients, it has zeros at -1, 4, and 4 + 4i, and it has the value of -150 at x = 1.

A polynomial is a mathematical expression that is composed of variables and coefficients, which are combined using only addition, subtraction, and multiplication. The variables in a polynomial can be raised to whole number powers, and the highest degree of a polynomial (i.e., the highest power to which a variable is raised) is known as the degree of the polynomial. For example, the polynomial 3x^2 + 2x + 1 has a degree of 2. The terms in a polynomial are usually arranged in descending order of degree, so that the first term has the highest degree and the last term has a degree of zero. The sum or difference of two or more polynomials is also a polynomial.

To find an nth-degree polynomial function with real coefficients that satisfies the given conditions, we can use the following process:

1. Write the polynomial in factored form using the zeros:

p(x) = a(x-1)(x-4)(x-(4+4i))(x-(4-4i))

2. Use the value of f(1) to find the leading coefficient a:

f(1) = p(1) = a(0)(0)(0)(0) = -150

a = -150

3. Write the polynomial in expanded form:

p(x) = -150(x-1)(x-4)(x-(4+4i))(x-(4-4i))

The resulting polynomial function is:

p(x) = -150(x-1)(x-4)(x-(4+4i))(x-(4-4i))

This function satisfies the conditions given: it is an nth-degree polynomial with real coefficients, it has zeros at -1, 4, and 4 + 4i, and it has the value of -150 at x = 1.

To calculate this, we use the formula for the perimeter of a square: P = 4s, where P is the perimeter and s is the length of one side. Since the length of one side of a square mile is 5,280 feet, we can calculate the perimeter of a square mile in feet: P = 4(5280 ft) = 21,120 ft. Since one dollar bill is 6.14 inches long, we can convert this to feet by dividing by 12 (1 ft = 12 inches): 21,120 ft / 12 inches/ft = 1,760 ft. Finally, we can calculate the number of dollar bills needed by dividing the perimeter in feet by the length of the dollar bill in feet: 1,760 ft / 0.514 ft = 33,792,000 dollar bills.
