The main span of a suspension bridge is the roadway between the bridges towers. The main span of the Walt Whitman Bridge in Philadelphia is 2000 feet long. This is 600 feet longer than two-fifths of the length of the main span of the George Washington Bridge in New York City. Write an equation to represent the given problem and solve it to find the length of the main span of the George Washington Bridge

Answers

The length of the main span of the George Washington Bridge is 3500 feet.

Let x be the length of the main span of the George Washington Bridge.

We know that the main span of the Walt Whitman Bridge is 600 feet longer than two-fifths of the length of the main span of the George Washington Bridge, so we can write the equation:

2000 = (2/5)x + 600

To solve for x, we can start by isolating the term with x on one side of the equation:

(2/5)x = 2000 - 600

(2/5)x = 1400

Then, we can solve for x by multiplying both sides by the reciprocal of (2/5):

x = 1400 / (2/5)

x = 3500

Therefore, the length of the main span of the George Washington Bridge is 3500 feet.

A police unit has deployed a tracking system on a highway with a speed limit of 65 mph. A driver passes through one radar detector at 2pm and is traveling 60 mph at that moment. Then, the driver passes through a second radar detector 159 miles away at 4pm, again traveling 60 mph at that moment. However, a speeding ticket is being issued for this driver. When he asked for an explanation, the response was "Mean Value Theorem. " Explain. Your report should include:
i- Detailed explanation about the mean value theorem.
ii- Detailed calculation steps. ​

Answers

The Mean-Value-Theorem is being used to explain why the driver received a speeding ticket even though they were traveling at exactly 60 mph at both radar-detectors. It suggests that there must have been a moment during the trip where the driver's speed was above the speed limit.

The Mean-Value Theorem is a theorem from calculus that states that for a continuous function on a closed interval, there exists at least one point in the interval where the instantaneous rate of change (the derivative) of the function is equal to the average rate of change of the function over the interval.

In this case, the police unit used the two radar detectors to determine the average-speed of the driver between the two points. The distance between the two detectors is 159 miles, and the time it took for the driver to travel that distance was 2 hours (from 2pm to 4pm), so the average speed of the driver was 159/2 = 79.5 mph.

However, the speed-limit on the highway is 65 mph, so the driver was exceeding the speed limit and received a speeding-ticket.

how many minutes are required for 175 gpm to pass the entire 1500-foot length of a 12-inch diameter pipeline

Answers

To calculate the time required for 175 gallons per minute (gpm) to pass through a 1500-foot length of a pipeline with a 12-inch diameter, we can follow these steps:

Convert the diameter from inches to feet:

12 inches = 12/12 = 1 foot

Calculate the cross-sectional area of the pipeline using the formula for the area of a circle:

Area = π *[tex](radius)^2[/tex]

Radius = diameter/2 = 1/2 = 0.5 feet

Area = π *[tex](0.5)^2[/tex] = 0.785 square feet

Convert the flow rate from gallons per minute (gpm) to gallons per second (gps):

175 gpm = 175/60 gps

Calculate the velocity of the flow using the formula:

Velocity = Flow rate / Cross-sectional area

Velocity = (175/60) / 0.785 = 3.56 feet per second (rounded to two decimal places)

Calculate the time required to pass the entire 1500-foot length of the pipeline using the formula:

Time = Distance / Velocity

Time = 1500 / 3.56 = 421.35 seconds (rounded to two decimal places)

Convert the time from seconds to minutes:

421.35 seconds = 421.35/60 minutes = 7.02 minutes (rounded to two decimal places)

So, it would take approximately 7.02 minutes for a flow rate of 175 gpm to pass through the entire 1500-foot length of a 12-inch diameter pipeline.

Given PQR with angle P = 42°, angle R = 26°, and PQ = 19, solve the triangle. Round all answers to the nearest tenth.

Angle Q =__
QR =__
PR =__

Answers

The solutions to the triangle PQR are:

Angle Q ≈ 112°

Side QR ≈ 8.98

Side PR ≈ 13.71

To solve the triangle PQR, we can use the fact that the sum of the angles in a triangle is always 180°. So we can find angle Q by subtracting the measures of angles P and R from 180°:

angle Q = 180° - angle P - angle R

angle Q = 180° - 42° - 26°

angle Q = 112°

Now, we can use the law of sines to find the lengths of the sides QR and PR.

The law of sines states that in any triangle ABC, the following equation holds:

a/sin(A) = b/sin(B) = c/sin(C)

where a, b, and c are the side lengths of the triangle, and A, B, and C are the opposite angles, respectively.

Applying this formula to triangle PQR, we can write:

QR/sin(R) = PQ/sin(Q)

QR/sin(26°) = 19/sin(112°)

Solving for QR, we get:

QR = (19 × sin(26°))/sin(112°)

QR ≈ 8.98

Similarly, we can find PR by applying the law of sines to triangle PQR as follows:

PR/sin(P) = PQ/sin(Q)

PR/sin(42°) = 19/sin(112°)

Solving for PR, we get:

PR = (19 × sin(42°))/sin(112°)

PR ≈ 13.71

Fill in the table by converting from 12 hour clock to 24 hour clock and vice versa ​

Answers

Converting time from the 12-hour clock format to the 24-hour clock format, and vice versa, can be a bit confusing at times, but it's not that difficult once you know how to do it.

To convert from the 12-hour clock format to the 24-hour clock format, simply add 12 hours to any time after 12:00 p.m. For example, if it's 3:00 p.m., you add 12 hours to get 15:00 (3:00 p.m. in 24-hour format). If it's 11:00 p.m., you add 12 hours to get 23:00 (11:00 p.m. in 24-hour format).

Conversely, to convert from the 24-hour clock format to the 12-hour clock format, simply subtract 12 hours from any time after 12:00 p.m. For example, if it's 16:00 (4:00 p.m.) in 24-hour format, you subtract 12 hours to get 4:00 a.m. in the 12-hour format. If it's 22:00 (10:00 p.m.) in 24-hour format, you subtract 12 hours to get 10:00 a.m. in the 12-hour format.

To help you with these conversions, here is a table with some examples:

Calculate d²y/dx² y= 0.5x‐⁰.² d²y/dx²=

Answers

To calculate d²y/dx², we first need to find the first derivative of y, which is dy/dx. For y = 0.5x^-0.2, we can use the power rule of differentiation, which states that the derivative of x^n is n*x^(n-1). Therefore,

dy/dx = -0.1x^-1.2

To find the second derivative, d²y/dx², we need to differentiate dy/dx again. Using the power rule again, we get:

d²y/dx² = 0.12x^-2.2

This is the second derivative of y with respect to x.

In calculus, a derivative is a measure of how a function changes as its input changes. The second derivative is a measure of how the rate of change of the function itself changes as its input changes. It tells us about the curvature of the function at any given point.

In this case, we have calculated the second derivative of y, which gives us information about the rate of change of the slope of the function. If the second derivative is positive, the function is concave up (curving upward), and if it is negative, the function is concave down (curving downward). If the second derivative is zero, the function has an inflection point (a point where the curvature changes direction).

Overall, the second derivative is a powerful tool in calculus that helps us understand the behavior of functions in more detail.

Answers

The critical points are (t, y) = (t, 0) and (t, -4c/5).

To find the partial derivatives, we need to differentiate f(t, y) with respect to each variable separately.

f1(t, y) = ∂f/∂t = 0 (since there is no t term in the function)

fy(t, y) = ∂f/∂y = -12cy^3 + 15y^4

fz(t, y) = ∂^2f/∂t∂z = 0 (since there is no z term in the function)

fy(t, y) = ∂^2f/∂y∂z = 0 (since there is no z term in the function)

So, 2. - f1(,y) fy(x, y) = = frz(, y) = fry(x, y) = 0 - 12cy^3 + 15y^4 = 0  (since f1(,y) and frz(, y) and fry(x, y) are all 0)

Therefore, -12cy^3 + 15y^4 = 0

Factor out y^3:

y^3(-12c + 15y) = 0

A business award is in the shape of a regular hexagonal pyramid. the height of the award is 95 millimeters and the base edge is 44 millimeters.



what is the surface area of the pyramid to the nearest square millimeter?

Answers

The surface area of the hexagonal pyramid is 75240 square millimeters to the nearest square millimeter.

The surface area of the hexagonal pyramid can be calculated by finding the sum of the areas of its faces. The hexagonal pyramid has a base with six equal sides of length 44 millimeters, and six identical triangular faces with a height of 95 millimeters.

Each triangular face is an isosceles triangle, with two sides of length 44 millimeters and a base of length equal to the perimeter of the hexagonal base, which is 6 times 44 millimeters, or 264 millimeters.

To calculate the area of each triangular face, we can use the formula for the area of an isosceles triangle, which is (base x height) / 2. Substituting the values we have, we get: Area of each triangular face = (264 x 95) / 2 = 12540 square millimeters

Since the hexagonal pyramid has six identical triangular faces, we can multiply the area of one triangular face by 6 to get the total surface area of the pyramid: Total surface area = 6 x 12540 = 75240 square millimeters.

From the pre-image point, calculate the image. The listed pre-image point is (x , y). Change the x and y coordinates, then multiply this same previous y coordinate by -1 to get a 90 degree anticlockwise rotation. Use the guidelines mentioned below to calculate each rotation.

Clockwise :

90 degree rotation: (x , y) ----> (y , -x)180 degree rotation: (x , y) ----> (-x , -y)270 degree rotation: (x , y) ----> (-y , x)

Given :

F(2, 4), I(5, 4) and G(3, 2)

After 90 degree rotation: (x , y) ----> (y , -x)

F'(4,-2), I'(4,-5) and G'(2,-3).

Thus, the coordinates of ΔF'I'G' after a rotation of 90° clockwise about the origin. are - F'(4,-2), I'(4,-5) and G'(2,-3).

Graphs for the both triangles are obtained.

What is the horizontal distance between (16, -24) to (-3, -24)
-13 units
-19 units
13 units
19 units

Answers

The horizontal distance between (16, -24) and (-3, -24) is 19 units.

Explanation:

We can calculate the horizontal distance by finding the difference between the x-coordinates of the two points.

Horizontal distance = difference in x-coordinates = (-3) - 16 = -19

However, the distance is negative, which doesn't make sense as distance is always positive. So we take the absolute value of the difference to get the actual distance.

|Horizontal distance| = |-19| = 19

Therefore, the horizontal distance between the two points is 19 units.

3. The table below shows the relationship between the amount of electricity used by a customer in different months and the cost shown on the customer's electric bill. Month 1 2 3 4 Monthly Electric Bills for a Customer Amount of Electricity Used (kilowatt-hours) A 0.095x < 65.00 B. 0.095x> 65.00 C. 0.92x < 65.00 D. 0.92x> 65.00 290 350 460 500 Cost of Electricity Used ($) 27.55 33.25 43.70 47.50 Based on the information shown in the table, which inequality could be used to determine all the numbers of kilowatt-hours (x) of electricity a customer could use in a month for the cost to be less than $65.00?

Answers

The correct inequality is:

A. 0.095x < 65.00.

To determine the inequality that represents the numbers of kilowatt-hours a customer could use in a month for the cost to be less than $65.00, we need to look for the rate at which the cost of electricity changes with the amount of electricity used.

From the table, we can see that the cost of electricity increases as the amount of electricity used increases.

We can also see that the cost per kilowatt-hour (the rate) is not constant. For example, the cost per kilowatt-hour for the first month is:

27.55 / 290 ≈ 0.095

But for the fourth month, it is:

47.50 / 500 ≈ 0.095

This means that the rate is not constant, and we cannot simply use a proportion to determine the numbers of kilowatt-hours that will result in a cost of less than $65.00.

However, we can use the data to create an inequality that represents the numbers of kilowatt-hours that will result in a cost less than $65.00. We can start by finding the highest cost per kilowatt-hour:

43.70 / 460 ≈ 0.095

This means that the cost per kilowatt-hour is always less than or equal to 0.095.

Next, we can set up the inequality:

0.095x < 65.00

This inequality represents the numbers of kilowatt-hours that will result in a cost less than $65.00, because if the cost per kilowatt-hour is always less than or equal to 0.095, then the total cost will be less than $65.00 if and only if the number of kilowatt-hours used is less than 684.21 (which is the result of dividing $65.00 by 0.095).

How to solve the system of equations?

The system of equations in the context of this problem is defined as follows:

3y - 6x = 24.8 + 2x = y.

Replacing the second equation into the first, the value of x is obtained as follows:

3(8 + 2x) - 6x = 24

24 + 6x - 6x = 24

24 = 24.

24 = 24 is a statement that is always true, hence the system has an infinite number of solutions, and thus option B is the correct option for this problem.

A. angle CXD = 140 degrees

Angle XCD and Angle XDC are congruent since the triangle is isosceles. Remember that the sum of the interior angles of a triangle is 180 degrees.

20 + 20 + x = 180

x = 140

B. 18 sides

To find the number of sides of the polygon, we need to know the measure of one interior angle. One interior angle is angle BCD. We can easily find the measure of this angle because it is on a straight angle of which we are given part of (angle XCD).

Angle XCD + Angle BCD = 180

20 + BCD = 180

BCD = 160

Now that we know the measure of an interior angle, we can use the formula to find the measure of an interior angle and algebraically solve for the number of sides.

[ (n - 2) x 180 ] / n = 160

(n - 2) x 180 = 160n

180n - 360 = 160n

-360 = -20n

n = 18 sides

C. 2880 degrees

The formula for the sum of the interior angles of a regular polygon is (n - 2) x 180, where n is the number of sides.

(18 - 2) x 180

16 x 180

2880

D. 140 degrees

If angle XCD is 20 degrees, then angle BED is also 20 degrees. Angle BED and Angle BEF make up one of the interior angles of the regular polygon. We know that one interior angle is equal to 160 degrees.

Angle BED + Angle BEF = 160

20 + BEF = 160

BEF = 140

Hope this helps!

1. Use integration in cylindrical coordinates in order to compute the vol- ume of: U = {(x,y,z):05:36 - 12 - y}

Answers

The  volume of the region U is 16π cubic units.

To find the volume of the region U, we can use cylindrical coordinates. In cylindrical coordinates, a point in space is represented by the coordinates (r, θ, z), where r is the distance from the z-axis, θ is the angle between the x-axis and the projection of the point onto the xy-plane, and z is the height above the xy-plane.

In this case, the region U is defined by 0 ≤ r ≤ 2, 0 ≤ θ ≤ 2π, and 0 ≤ z ≤ 12 - r sin(θ).

To find the volume of U, we can integrate over the cylindrical coordinates. The volume of U is given by the integral:

V = ∫∫∫_U dV

where dV = r dz dr dθ is the volume element in cylindrical coordinates.

Substituting in the limits of integration, we have:

V = ∫₀²π ∫₀² ∫₀^(12-rsinθ) r dz dr dθ

Integrating with respect to z, we get:

V = ∫₀²π ∫₀² r(12-rsinθ) dr dθ

Integrating with respect to r, we get:

V = ∫₀²π [(6r² - (1/3)r³sinθ)] from r=0 to r=2 dθ

Simplifying, we get:

V = ∫₀²π [(24 - 16/3 sinθ)] dθ

Integrating, we get:

V = [24θ + 16/3 cosθ] from θ=0 to θ=2π

Simplifying, we get:

V = 48π/3 = 16π

Therefore, the volume of the region U is 16π cubic units.

A tree’s cross sectional area is called its basal area and is measured in square inches. Tree growth can be measured by the growth of the tree’s basal area. The initial base area of tree observed by a biologist is 154 square inches and annual growth rate is 6%. What will be the basal area after 10 years of growth?

Answers

The basal area of the tree after 10 years of growth would be approximately 279.7 square inches.

Given the initial basal area of a tree, which is 154 square inches, and the annual growth rate, which is 6%. To find out what the basal area of the tree will be after 10 years of growth.

By using the formula for compound interest, which can be applied to the growth of the basal area over time. The formula is:

A = P(1 + r)ⁿ

where:

A is the final amount

P is the initial amount

r is the annual growth rate

n is the number of years

To find A, the final basal area of the tree after 10 years of growth. We know that P is 154 square inches, r is 6% or 0.06 and n is 10.

By applying these values in the formula, we get:

A = 154(1 + 0.06)¹⁰

A = 154(1.06)¹⁰

A = ≈ 279.7

Therefore, the basal area of the tree after 10 years of growth would be approximately 279.7 square inches.
