Using the conversion factors, we find that 3 cubic miles is approximately equal to 1.2504543 × 10^10 cubic meters. 5 cubic feet per second is equal to 2244.156 gallons per minute. 9.50 centimeters is equal to 9.50 * 10^7 nanometers per second squared.

1.1. One mile is equal to 1609.34 meters. Since we're dealing with cubic units, we cube the conversion factor.

1 mile = 1609.34 meters

1 mile³ = (1609.34 meters)³ = 4.168181 × 10^9 cubic meters

Therefore, 3 cubic miles is equal to 3 * 4.168181 × 10^9 cubic meters, which is approximately 1.2504543 × 10^10 cubic meters.

1.2. To convert from cubic feet per second (ft³/s) to gallons per minute (gal/min), we use the appropriate conversion factors.

Here are the conversion factors:

1 cubic foot = 7.48052 gallons

1 minute = 60 seconds

So, we set up the conversion as follows:

5 ft³/s * 7.48052 gal/ft³ * 60 s/min = 2244.156 gal/min

Therefore, 5 cubic feet per second is equal to 2244.156 gallons per minute.

1.3. To convert centimeters (cm) to nanometers per second squared (nm/sec²), we use the appropriate conversion factors. Here are the conversion factors:

1 centimeter = 10^7 nanometers

1 second = 1 second

So, we set up the conversion as follows:

9.50 cm * (10^7 nm/cm) / (1 sec)² = 9.50 * 10^7 nm/sec²

Therefore, 9.50 centimeters is equal to 9.50 * 10^7 nanometers per second squared.

Answer:

the answer 6.5

........

The distance between the points R(0, 1) and S(6, 3.5) is 6.5 units after using the distance formula.

It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.

The distance formula can be given as:

\(\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

It is given that:

Two points are:

R(0, 1) and S(6, 3.5)

To find the distance between points R and S we can use the distance formula.

\(\rm d=\sqrt{(6-0)^2+(3.5-1)^2}\\\)

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

d = √(36 + 6.25)

d = √42.25

d = 6.5 units

Thus, the distance between the points R(0, 1) and S(6, 3.5) is 6.5 units after using the distance formula.

After considering the given data we conclude that the distance between stone and ground level \(h(t) = -4.9t^2 + 900\), time taken for the stone to reach the ground 18.22 seconds,the velocity with which it strikes the ground 178.76 m/s, if thrown with a down ward speed of 3m/s then the duration needed is 18.47 seconds.

A stone is dropped from the upper observation deck of a tower, 900 m above the ground. We can use the kinematic equations of motion to answer the following questions:
a) The distance of the stone above ground level at time t can be found using the equation:
\(h(t) = -1/2gt^2 + v_0t + h_0\)
where g is the acceleration due to gravity (9.8 m/s²), v0 is the initial velocity (0 m/s), h0 is the initial height (900 m), and t is the time elapsed. Plugging in the values, we get:
\(h(t) = -4.9t^2 + 900\)
b) To find how long it takes for the stone to reach the ground, we need to find the time when h(t) = 0:
\(-4.9t^2 + 900 = 0\)
Solving for t, we get:
\(t = \sqrt(900/4.9) = 18.22 seconds\)
Therefore, it takes the stone 18.22 seconds to reach the ground.
c) To find the velocity with which the stone strikes the ground, we can use the equation:
\(v(t) = -gt + v_0\)
where v(t) is the velocity at time t. Plugging in the values, we get:
\(v(t) = -9.8(18.22) + 0 = -178.76 m/s\)
Therefore, the stone strikes the ground with a velocity of 178.76 m/s.
d) If the stone is thrown downward with a speed of 3 m/s, we can use the same equation \(v(t) = -9.8(18.22) + 0 = -178.76 m/s\) to find how long it takes to reach the ground. This time, \(v_0\) is -3 m/s (since it is thrown downward) and \(h_0\) is still 900 m. Plugging in the values, we get:
\(-4.9t^2 - 3t + 900 = 0\)
Solving for t, we get:
t = 18.47 seconds
Therefore, it takes the stone 18.47 seconds to reach the ground when thrown downward with a speed of 3 m/s.

The direct and Inverse variation relationship,x = 2 and z = 1, the value of y is 12.

the direct and inverse variation relationship:

y = k * (x^2) / z

where k is the constant of variation.

Given that y = 4 when x = 4 and z = 12, we can substitute these values into the equation:

4 = k * (4^2) / 12

Simplifying, we have:

4 = k * 16 / 12

To solve for k, we can cross-multiply and divide:

4 * 12 = k * 16

48 = 16k

Dividing both sides by 16:

48 / 16 = k

k = 3

Now that we have determined the value of k, we can use it to find y when x = 2 and z = 1.

Substituting these values into the equation, we have:

y = 3 * (2^2) / 1

Simplifying further

y = 3 * 4 / 1

y = 12

Therefore, when x = 2 and z = 1, the value of y is 12.

By solving the equation. y-y_(1)=m(x-x_(1)) y-(-3)=-4(x-2) y+3=-4x+8 y=-4x+5 using the point-slope equation and substituting -4 for m and using point (2,-3) we get y = -4x + 5 equation of line.

Given that the slope of the perpendicular line is the negative reciprocal of (1)/(4), or -4. So, the slope of the line passing through the point (2, -3)  is perpendicular to the given line is -4.

Now use the point-slope equation of a line which is given by y - y1 = m(x - x1)

To solve the formula A=9R/I for I, we need to rearrange the equation to isolate the variable I.  By plugging in the values for A and R into the equation, we can determine the number of innings pitched.

Starting with the formula A=9R/I, we want to solve for I. To do this, we can begin by multiplying both sides of the equation by I to eliminate the fraction. This gives us AI = 9R.

Next, we want to isolate the variable I. To do so, we can divide both sides of the equation by A. This gives us AI/A = 9R/A, which simplifies to I = 9R/A.

Therefore, the solution to the formula A=9R/I for I is I = 9R/A. This equation allows us to calculate the number of innings pitched (I) when given the earned run average (A) and the runs allowed (R).By plugging in the values for A and R into the equation, we can determine the number of innings pitched.

The equation used in writing a partial fraction decomposition is given as:

Negative 15 x + 10 / (5 x - 2) = a / (5 x - 2) + b / (5 x - 2).

To determine the values of a and b, we can use a system of equations. This system of equations consists of two equations, one for a and one for b. The equation for a is: Negative 15 x + 10 = a * (5 x - 2). The equation for b is: 0 = b * (5 x - 2). We can solve these equations simultaneously to get the values of a and b.

For example, if x = 1, then the equation for a becomes: Negative 15 + 10 = a * (5 - 2), which simplifies to -5 = a * 9. Therefore, a = -5/9. The equation for b becomes: 0 = b * (5 - 2), which simplifies to 0 = b * 3. Therefore, b = 0.

In summary, the system of equations used to determine the values of a and b is:

Negative 15 x + 10 = a * (5 x - 2) and 0 = b * (5 x - 2). By solving these equations simultaneously, we can get the values of a and b.

We can be 97% confident that the true proportion of college graduates in Ohio who voted for George Bush in the 2004 presidential election lies between 0.59 and 0.69.

To construct the confidence interval, we first need to calculate the sample proportion of college graduates in Ohio who voted for George Bush:

P = 480/750 = 0.64

Next, we need to calculate the standard error of the sample proportion:

SE = \(\sqrt{}\)((P(1-P))/n) = \(\sqrt{}\)((0.64 x 0.36)/750) = 0.025

To construct a two-sided confidence interval with a confidence level of 97%, we need to find the critical values from the t-distribution with degrees of freedom equal to the sample size minus 1:

t* = t(0.015, 749) ≈ 2.356

where t(0.015, 749) represents the 0.015th percentile of the t-distribution with 749 degrees of freedom. We use the 0.015th percentile instead of the 0.025th percentile because we are constructing a two-sided confidence interval.

Finally, we can construct the confidence interval using the formula:

P ± t*SE

Substituting the values, we get:

0.64 ± 2.356 x 0.025

Simplifying, we get:

(0.59, 0.69)

Therefore, we can be 97% confident that the true proportion of college graduates in Ohio who voted for George Bush in the 2004 presidential election lies between 0.59 and 0.69.
