The spacecraft would take approximately 7 hours to reach the moon from Earth.

The moon is 2.4 x 10 5 miles from earth.

Assume the speed of the fastest spacecraft is 3.6 x 10 4 miles per hour.

How many hours would it take this spacecraft to fly to the moon from earth:

The question is asking how many hours it would take a spacecraft that is traveling at a speed of 3.6 x 10 4 miles per hour to fly from Earth to the Moon, which is 2.4 x 10 5 miles away.

This problem can be solved using the formula:  

distance = rate x time.

To find the time it would take to travel to the moon,

we need to rearrange the formula to solve for time.

time = distance / rate.

Plugging in the given values:

distance = 2.4 x 10 5 milesrate.

= 3.6 x 10 4 miles per hour

time = (2.4 x 10 5) / (3.6 x 10 4)

time = 6.67 hours

Rounding to the nearest hour, the spacecraft would take 7 hours to fly to the moon from Earth.

The smallest p-value is always associated with the z-score that is furthest away from the mean. This is because the tails of the normal distribution curve have less area and thus represent smaller p-values. The correct answer is option (d) z = -3.24.

In a hypothesis test, there are two hypotheses: the null hypothesis (H0) and the alternative hypothesis (H1).

The null hypothesis is the one we're testing, while the alternative hypothesis is the one we're trying to support or prove.

A two-tailed alternative hypothesis is one in which we are interested in whether a parameter is not equal to a certain value, as opposed to one-tailed alternative hypotheses, in which we are interested in whether the parameter is greater than or less than a certain value.

The second approximation to the root of the equation x³ - 9 = 0 using Newton's method with the initial approximation x₁ = -2 is approximately x₂ = -0.5833.

To apply Newton's method to find the second approximation, x₂, to the root of the equation x³ - 9 = 0, we follow these steps:

Determine the function and its derivative.

Let f(x) = x³ - 9 be the given equation. The derivative of f(x) is f'(x) = 3x².

Choose an initial approximation.

In this case, the given initial approximation is x₁ = -2.

Apply Newton's method formula.

The formula for Newton's method is:

xₙ₊₁ = xₙ - f(xₙ) / f'(xₙ)

We start with x₁ = -2 and substitute it into the formula to find x₂:

x₂ = x₁ - f(x₁) / f'(x₁)

Calculate x₂.

Substituting the values into the formula:

x₂ = -2 - ( (-2)³ - 9 ) / (3(-2)²)

= -2 - ( -8 - 9 ) / (3 * 4)

= -2 - ( -17 ) / 12

= -2 + 17 / 12

= -2 + 1.4167

= -0.5833

-6a² + 4a² + 3 is the quotient of the given expression: (36a⁴- 24a⁴ - 18a²) ÷ (-6a²).

It is known as the quotient to divide two integers. The dividend is the quantity being divided, and the divisor is the quantity being divided. The quotient is the outcome of the division.

The sum is the result of multiplying two or more numbers together. The difference is determined by the result of subtracting the two values. The result of multiplying two or more integers is what is known as the product. The quotient is what remains after dividing two numbers.

Given that,

= (36a⁴- 24a⁴ - 18a²) ÷ (-6a²)

= - 6a² + 4a² + 3

thus, -6a² + 4a² + 3 is the quotient of the above expression.

Answer:

2k

Step-by-step explanation:

-k is the same as -1k so you can just solve it like that. Also, when adding terms with variables you just add the number in front (if they have the same variable). So -1k + 3k = 2k. Pretty much the same as -1 + 3, you just add a variable..

Answer:

each book saves $295.6875

Step-by-step explanation:

Let the number of book be n

Total cost = 750 + (n-1)*25

For 100 books

cost = 750 + 99*25 = $3225

each book costs = $322.5

For 400 books

cost = 750 + 399*25 = $10725

each book costs = $26.8125

each book saves $295.6875

there are two values of x in the interval where the instantaneous rate of change of is equal to the average rate of change of over the interval.

To find the average rate of change of over the interval , we need to calculate the slope of the line passing through the two endpoints of the interval.

The slope of the line passing through the points and is given by:

( - )/( - ) = ( -3 - 3)/(1 - (-1)) = -6/2 = -3

Therefore, the average rate of change of over the interval is -3.

To find how many values of in the interval have instantaneous rate of change equal to the average rate of change, we need to find the derivative of :

f'(x) = 3x^2 - 3x - 3

Setting f'(x) equal to the average rate of change, we get:

3x^2 - 3x - 3 = -3

Simplifying the equation, we get:

3x^2 - 3x = 0

Factoring out 3x, we get:

3x(x - 1) = 0

Therefore, the solutions are x = 0 and x = 1.

Answer:

Steps to find the equation of a line from two points:

Find the slope using the slope formula

Use the slope and one of the points to solve for the y-intercept (b).

One of your points can replace the x and y, and the slope you just calculated replaces the m of your equation y = mx + b. Then b is the only variable left. Use the tools you know for solving for a variable to solve for b.

Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line.
